How to Write a Research Paper Introduction (with Examples)

The research paper introduction section, along with the Title and Abstract, can be considered the face of any research paper. The following article is intended to guide you in organizing and writing the research paper introduction for a quality academic article or dissertation.

The research paper introduction aims to present the topic to the reader. A study will only be accepted for publishing if you can ascertain that the available literature cannot answer your research question. So it is important to ensure that you have read important studies on that particular topic, especially those within the last five to ten years, and that they are properly referenced in this section. 1 What should be included in the research paper introduction is decided by what you want to tell readers about the reason behind the research and how you plan to fill the knowledge gap. The best research paper introduction provides a systemic review of existing work and demonstrates additional work that needs to be done. It needs to be brief, captivating, and well-referenced; a well-drafted research paper introduction will help the researcher win half the battle.

The introduction for a research paper is where you set up your topic and approach for the reader. It has several key goals:

  • Present your research topic
  • Capture reader interest
  • Summarize existing research
  • Position your own approach
  • Define your specific research problem and problem statement
  • Highlight the novelty and contributions of the study
  • Give an overview of the paper’s structure

The research paper introduction can vary in size and structure depending on whether your paper presents the results of original empirical research or is a review paper. Some research paper introduction examples are only half a page while others are a few pages long. In many cases, the introduction will be shorter than all of the other sections of your paper; its length depends on the size of your paper as a whole.

The introduction in a research paper is placed at the beginning to guide the reader from a broad subject area to the specific topic that your research addresses. They present the following information to the reader

  • Scope: The topic covered in the research paper
  • Context: Background of your topic
  • Importance: Why your research matters in that particular area of research and the industry problem that can be targeted

The research paper introduction conveys a lot of information and can be considered an essential roadmap for the rest of your paper. A good introduction for a research paper is important for the following reasons:

  • It stimulates your reader’s interest: A good introduction section can make your readers want to read your paper by capturing their interest. It informs the reader what they are going to learn and helps determine if the topic is of interest to them.
  • It helps the reader understand the research background: Without a clear introduction, your readers may feel confused and even struggle when reading your paper. A good research paper introduction will prepare them for the in-depth research to come. It provides you the opportunity to engage with the readers and demonstrate your knowledge and authority on the specific topic.
  • It explains why your research paper is worth reading: Your introduction can convey a lot of information to your readers. It introduces the topic, why the topic is important, and how you plan to proceed with your research.
  • It helps guide the reader through the rest of the paper: The research paper introduction gives the reader a sense of the nature of the information that will support your arguments and the general organization of the paragraphs that will follow. It offers an overview of what to expect when reading the main body of your paper.

What are the parts of introduction in the research?

A good research paper introduction section should comprise three main elements: 2

  • What is known: This sets the stage for your research. It informs the readers of what is known on the subject.
  • What is lacking: This is aimed at justifying the reason for carrying out your research. This could involve investigating a new concept or method or building upon previous research.
  • What you aim to do: This part briefly states the objectives of your research and its major contributions. Your detailed hypothesis will also form a part of this section.

How to write a research paper introduction?

The first step in writing the research paper introduction is to inform the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening statement. The second step involves establishing the kinds of research that have been done and ending with limitations or gaps in the research that you intend to address. Finally, the research paper introduction clarifies how your own research fits in and what problem it addresses. If your research involved testing hypotheses, these should be stated along with your research question. The hypothesis should be presented in the past tense since it will have been tested by the time you are writing the research paper introduction.

The following key points, with examples, can guide you when writing the research paper introduction section:

  • Highlight the importance of the research field or topic
  • Describe the background of the topic
  • Present an overview of current research on the topic

Example: The inclusion of experiential and competency-based learning has benefitted electronics engineering education. Industry partnerships provide an excellent alternative for students wanting to engage in solving real-world challenges. Industry-academia participation has grown in recent years due to the need for skilled engineers with practical training and specialized expertise. However, from the educational perspective, many activities are needed to incorporate sustainable development goals into the university curricula and consolidate learning innovation in universities.

  • Reveal a gap in existing research or oppose an existing assumption
  • Formulate the research question

Example: There have been plausible efforts to integrate educational activities in higher education electronics engineering programs. However, very few studies have considered using educational research methods for performance evaluation of competency-based higher engineering education, with a focus on technical and or transversal skills. To remedy the current need for evaluating competencies in STEM fields and providing sustainable development goals in engineering education, in this study, a comparison was drawn between study groups without and with industry partners.

  • State the purpose of your study
  • Highlight the key characteristics of your study
  • Describe important results
  • Highlight the novelty of the study.
  • Offer a brief overview of the structure of the paper.

Example: The study evaluates the main competency needed in the applied electronics course, which is a fundamental core subject for many electronics engineering undergraduate programs. We compared two groups, without and with an industrial partner, that offered real-world projects to solve during the semester. This comparison can help determine significant differences in both groups in terms of developing subject competency and achieving sustainable development goals.

The purpose of the research paper introduction is to introduce the reader to the problem definition, justify the need for the study, and describe the main theme of the study. The aim is to gain the reader’s attention by providing them with necessary background information and establishing the main purpose and direction of the research.

The length of the research paper introduction can vary across journals and disciplines. While there are no strict word limits for writing the research paper introduction, an ideal length would be one page, with a maximum of 400 words over 1-4 paragraphs. Generally, it is one of the shorter sections of the paper as the reader is assumed to have at least a reasonable knowledge about the topic. 2 For example, for a study evaluating the role of building design in ensuring fire safety, there is no need to discuss definitions and nature of fire in the introduction; you could start by commenting upon the existing practices for fire safety and how your study will add to the existing knowledge and practice.

When deciding what to include in the research paper introduction, the rest of the paper should also be considered. The aim is to introduce the reader smoothly to the topic and facilitate an easy read without much dependency on external sources. 3 Below is a list of elements you can include to prepare a research paper introduction outline and follow it when you are writing the research paper introduction. Topic introduction: This can include key definitions and a brief history of the topic. Research context and background: Offer the readers some general information and then narrow it down to specific aspects. Details of the research you conducted: A brief literature review can be included to support your arguments or line of thought. Rationale for the study: This establishes the relevance of your study and establishes its importance. Importance of your research: The main contributions are highlighted to help establish the novelty of your study Research hypothesis: Introduce your research question and propose an expected outcome. Organization of the paper: Include a short paragraph of 3-4 sentences that highlights your plan for the entire paper

Cite only works that are most relevant to your topic; as a general rule, you can include one to three. Note that readers want to see evidence of original thinking. So it is better to avoid using too many references as it does not leave much room for your personal standpoint to shine through. Citations in your research paper introduction support the key points, and the number of citations depend on the subject matter and the point discussed. If the research paper introduction is too long or overflowing with citations, it is better to cite a few review articles rather than the individual articles summarized in the review. A good point to remember when citing research papers in the introduction section is to include at least one-third of the references in the introduction.

The literature review plays a significant role in the research paper introduction section. A good literature review accomplishes the following: Introduces the topic – Establishes the study’s significance – Provides an overview of the relevant literature – Provides context for the study using literature – Identifies knowledge gaps However, remember to avoid making the following mistakes when writing a research paper introduction: Do not use studies from the literature review to aggressively support your research Avoid direct quoting Do not allow literature review to be the focus of this section. Instead, the literature review should only aid in setting a foundation for the manuscript.

Remember the following key points for writing a good research paper introduction: 4

  • Avoid stuffing too much general information: Avoid including what an average reader would know and include only that information related to the problem being addressed in the research paper introduction. For example, when describing a comparative study of non-traditional methods for mechanical design optimization, information related to the traditional methods and differences between traditional and non-traditional methods would not be relevant. In this case, the introduction for the research paper should begin with the state-of-the-art non-traditional methods and methods to evaluate the efficiency of newly developed algorithms.
  • Avoid packing too many references: Cite only the required works in your research paper introduction. The other works can be included in the discussion section to strengthen your findings.
  • Avoid extensive criticism of previous studies: Avoid being overly critical of earlier studies while setting the rationale for your study. A better place for this would be the Discussion section, where you can highlight the advantages of your method.
  • Avoid describing conclusions of the study: When writing a research paper introduction remember not to include the findings of your study. The aim is to let the readers know what question is being answered. The actual answer should only be given in the Results and Discussion section.

To summarize, the research paper introduction section should be brief yet informative. It should convince the reader the need to conduct the study and motivate him to read further.

Research Paper Introduction

Research Paper Introduction

Research paper introduction is the first section of a research paper that provides an overview of the study, its purpose, and the research question (s) or hypothesis (es) being investigated. It typically includes background information about the topic, a review of previous research in the field, and a statement of the research objectives. The introduction is intended to provide the reader with a clear understanding of the research problem, why it is important, and how the study will contribute to existing knowledge in the field. It also sets the tone for the rest of the paper and helps to establish the author’s credibility and expertise on the subject.

How to Write Research Paper Introduction

Writing an introduction for a research paper can be challenging because it sets the tone for the entire paper. Here are some steps to follow to help you write an effective research paper introduction:

  • Start with a hook : Begin your introduction with an attention-grabbing statement, a question, or a surprising fact that will make the reader interested in reading further.
  • Provide background information: After the hook, provide background information on the topic. This information should give the reader a general idea of what the topic is about and why it is important.
  • State the research problem: Clearly state the research problem or question that the paper addresses. This should be done in a concise and straightforward manner.
  • State the research objectives: After stating the research problem, clearly state the research objectives. This will give the reader an idea of what the paper aims to achieve.
  • Provide a brief overview of the paper: At the end of the introduction, provide a brief overview of the paper. This should include a summary of the main points that will be discussed in the paper.
  • Revise and refine: Finally, revise and refine your introduction to ensure that it is clear, concise, and engaging.

Structure of Research Paper Introduction

The following is a typical structure for a research paper introduction:

  • Background Information: This section provides an overview of the topic of the research paper, including relevant background information and any previous research that has been done on the topic. It helps to give the reader a sense of the context for the study.
  • Problem Statement: This section identifies the specific problem or issue that the research paper is addressing. It should be clear and concise, and it should articulate the gap in knowledge that the study aims to fill.
  • Research Question/Hypothesis : This section states the research question or hypothesis that the study aims to answer. It should be specific and focused, and it should clearly connect to the problem statement.
  • Significance of the Study: This section explains why the research is important and what the potential implications of the study are. It should highlight the contribution that the research makes to the field.
  • Methodology: This section describes the research methods that were used to conduct the study. It should be detailed enough to allow the reader to understand how the study was conducted and to evaluate the validity of the results.
  • Organization of the Paper : This section provides a brief overview of the structure of the research paper. It should give the reader a sense of what to expect in each section of the paper.

Research Paper Introduction Examples

Research Paper Introduction Examples could be:

Example 1: In recent years, the use of artificial intelligence (AI) has become increasingly prevalent in various industries, including healthcare. AI algorithms are being developed to assist with medical diagnoses, treatment recommendations, and patient monitoring. However, as the use of AI in healthcare grows, ethical concerns regarding privacy, bias, and accountability have emerged. This paper aims to explore the ethical implications of AI in healthcare and propose recommendations for addressing these concerns.

Example 2: Climate change is one of the most pressing issues facing our planet today. The increasing concentration of greenhouse gases in the atmosphere has resulted in rising temperatures, changing weather patterns, and other environmental impacts. In this paper, we will review the scientific evidence on climate change, discuss the potential consequences of inaction, and propose solutions for mitigating its effects.

Example 3: The rise of social media has transformed the way we communicate and interact with each other. While social media platforms offer many benefits, including increased connectivity and access to information, they also present numerous challenges. In this paper, we will examine the impact of social media on mental health, privacy, and democracy, and propose solutions for addressing these issues.

Example 4: The use of renewable energy sources has become increasingly important in the face of climate change and environmental degradation. While renewable energy technologies offer many benefits, including reduced greenhouse gas emissions and energy independence, they also present numerous challenges. In this paper, we will assess the current state of renewable energy technology, discuss the economic and political barriers to its adoption, and propose solutions for promoting the widespread use of renewable energy.

Purpose of Research Paper Introduction

The introduction section of a research paper serves several important purposes, including:

  • Providing context: The introduction should give readers a general understanding of the topic, including its background, significance, and relevance to the field.
  • Presenting the research question or problem: The introduction should clearly state the research question or problem that the paper aims to address. This helps readers understand the purpose of the study and what the author hopes to accomplish.
  • Reviewing the literature: The introduction should summarize the current state of knowledge on the topic, highlighting the gaps and limitations in existing research. This shows readers why the study is important and necessary.
  • Outlining the scope and objectives of the study: The introduction should describe the scope and objectives of the study, including what aspects of the topic will be covered, what data will be collected, and what methods will be used.
  • Previewing the main findings and conclusions : The introduction should provide a brief overview of the main findings and conclusions that the study will present. This helps readers anticipate what they can expect to learn from the paper.

When to Write Research Paper Introduction

The introduction of a research paper is typically written after the research has been conducted and the data has been analyzed. This is because the introduction should provide an overview of the research problem, the purpose of the study, and the research questions or hypotheses that will be investigated.

Once you have a clear understanding of the research problem and the questions that you want to explore, you can begin to write the introduction. It’s important to keep in mind that the introduction should be written in a way that engages the reader and provides a clear rationale for the study. It should also provide context for the research by reviewing relevant literature and explaining how the study fits into the larger field of research.

Advantages of Research Paper Introduction

The introduction of a research paper has several advantages, including:

  • Establishing the purpose of the research: The introduction provides an overview of the research problem, question, or hypothesis, and the objectives of the study. This helps to clarify the purpose of the research and provide a roadmap for the reader to follow.
  • Providing background information: The introduction also provides background information on the topic, including a review of relevant literature and research. This helps the reader understand the context of the study and how it fits into the broader field of research.
  • Demonstrating the significance of the research: The introduction also explains why the research is important and relevant. This helps the reader understand the value of the study and why it is worth reading.
  • Setting expectations: The introduction sets the tone for the rest of the paper and prepares the reader for what is to come. This helps the reader understand what to expect and how to approach the paper.
  • Grabbing the reader’s attention: A well-written introduction can grab the reader’s attention and make them interested in reading further. This is important because it can help to keep the reader engaged and motivated to read the rest of the paper.
  • Creating a strong first impression: The introduction is the first part of the research paper that the reader will see, and it can create a strong first impression. A well-written introduction can make the reader more likely to take the research seriously and view it as credible.
  • Establishing the author’s credibility: The introduction can also establish the author’s credibility as a researcher. By providing a clear and thorough overview of the research problem and relevant literature, the author can demonstrate their expertise and knowledge in the field.
  • Providing a structure for the paper: The introduction can also provide a structure for the rest of the paper. By outlining the main sections and sub-sections of the paper, the introduction can help the reader navigate the paper and find the information they are looking for.

1 What is the Importance of an Introduction?

An Introduction to a scientific paper familiarizes the reader with the background of the issue at hand. It must reflect why the issue is topical and its current importance in the vast sea of research being done globally. It lays the foundation of biomedical writing and is the first portion of an article according to the IMRAD pattern ( I ntroduction, M ethodology, R esults, a nd D iscussion) [ 1 ].

It provides the flavour of the article and many authors have used phrases to describe it for example—'like a gate of the city’ [ 2 ], ‘the beginning is half of the whole’ [ 3 ], ‘an introduction is not just wrestling with words to fit the facts, but it also strongly modulated by perception of the anticipated reactions of peer colleagues’, [ 4 ] and ‘an introduction is like the trailer to a movie’. A good introduction helps captivate the reader early.

figure a

2 What Are the Principles of Writing a Good Introduction?

A good introduction will ‘sell’ an article to a journal editor, reviewer, and finally to a reader [ 3 ]. It should contain the following information [ 5 , 6 ]:

The known—The background scientific data

The unknown—Gaps in the current knowledge

Research hypothesis or question

Methodologies used for the study

The known consist of citations from a review of the literature whereas the unknown is the new work to be undertaken. This part should address how your work is the required missing piece of the puzzle.

3 What Are the Models of Writing an Introduction?

The Problem-solving model

First described by Swales et al. in 1979, in this model the writer should identify the ‘problem’ in the research, address the ‘solution’ and also write about ‘the criteria for evaluating the problem’ [ 7 , 8 ].

The CARS model that stands for C reating A R esearch S pace [ 9 , 10 ].

The two important components of this model are:

Establishing a territory (situation)

Establishing a niche (problem)

Occupying a niche (the solution)

In this popular model, one can add a fourth point, i.e., a conclusion [ 10 ].

4 What Is Establishing a Territory?

This includes: [ 9 ]

Stating the general topic and providing some background about it.

Providing a brief and relevant review of the literature related to the topic.

Adding a paragraph on the scope of the topic including the need for your study.

5 What Is Establishing a Niche?

Establishing a niche includes:

Stating the importance of the problem.

Outlining the current situation regarding the problem citing both global and national data.

Evaluating the current situation (advantages/ disadvantages).

Identifying the gaps.

Emphasizing the importance of the proposed research and how the gaps will be addressed.

Stating the research problem/ questions.

Stating the hypotheses briefly.

Figure 17.1 depicts how the introduction needs to be written. A scientific paper should have an introduction in the form of an inverted pyramid. The writer should start with the general information about the topic and subsequently narrow it down to the specific topic-related introduction.

figure 1

Flow of ideas from the general to the specific

6 What Does Occupying a Niche Mean?

This is the third portion of the introduction and defines the rationale of the research and states the research question. If this is missing the reviewers will not understand the logic for publication and is a common reason for rejection [ 11 , 12 ]. An example of this is given below:

Till date, no study has been done to see the effectiveness of a mesh alone or the effectiveness of double suturing along with a mesh in the closure of an umbilical hernia regarding the incidence of failure. So, the present study is aimed at comparing the effectiveness of a mesh alone versus the double suturing technique along with a mesh.

7 How Long Should the Introduction Be?

For a project protocol, the introduction should be about 1–2 pages long and for a thesis it should be 3–5 pages in a double-spaced typed setting. For a scientific paper it should be less than 10–15% of the total length of the manuscript [ 13 , 14 ].

8 How Many References Should an Introduction Have?

All sections in a scientific manuscript except the conclusion should contain references. It has been suggested that an introduction should have four or five or at the most one-third of the references in the whole paper [ 15 ].

9 What Are the Important Points Which Should be not Missed in an Introduction?

An introduction paves the way forward for the subsequent sections of the article. Frequently well-planned studies are rejected by journals during review because of the simple reason that the authors failed to clarify the data in this section to justify the study [ 16 , 17 ]. Thus, the existing gap in knowledge should be clearly brought out in this section (Fig. 17.2 ).

figure 2

How should the abstract, introduction, and discussion look

The following points are important to consider:

The introduction should be written in simple sentences and in the present tense.

Many of the terms will be introduced in this section for the first time and these will require abbreviations to be used later.

The references in this section should be to papers published in quality journals (e.g., having a high impact factor).

The aims, problems, and hypotheses should be clearly mentioned.

Start with a generalization on the topic and go on to specific information relevant to your research.

10 Example of an Introduction

figure b

11 Conclusions

An Introduction is a brief account of what the study is about. It should be short, crisp, and complete.

It has to move from a general to a specific research topic and must include the need for the present study.

The Introduction should include data from a literature search, i.e., what is already known about this subject and progress to what we hope to add to this knowledge.

How to Write an Introduction for a Research Paper

Academic Writing Service

How to write an introduction for a research paper? Eventually (and with practice) all writers will develop their own strategy for writing the perfect introduction for a research paper. Once you are comfortable with writing, you will probably find your own, but coming up with a good strategy can be tough for beginning writers.

The Purpose of an Introduction

Your opening paragraphs, phrases for introducing thesis statements, research paper introduction examples, using the introduction to map out your research paper.

  • First write your thesis.Your thesis should state the main idea in specific terms.
  • After you have a working thesis, tackle the body of your paper before you write the rest of the introduction. Each paragraph in the body should explore one specific topic that proves, or summarizes your thesis. Writing is a thinking process. Once you have worked your way through that process by writing the body of the paper, you will have an intimate understanding of how you are supporting your thesis. After you have written the body paragraphs, go back and rewrite your thesis to make it more specific and to connect it to the topics you addressed in the body paragraph.
  • Revise your introduction several times, saving each revision. Be sure your introduction previews the topics you are presenting in your paper. One way of doing this is to use keywords from the topic sentences in each paragraph to introduce, or preview, the topics in your introduction.This “preview” will give your reader a context for understanding how you will make your case.
  • Experiment by taking different approaches to your thesis with every revision you make. Play with the language in the introduction. Strike a new tone. Go back and compare versions. Then pick the one that works most effectively with the body of your research paper.
  • Do not try to pack everything you want to say into your introduction. Just as your introduction should not be too short, it should also not be too long. Your introduction should be about the same length as any other paragraph in your research paper. Let the content—what you have to say—dictate the length.

The first page of your research paper should draw the reader into the text. It is the paper’s most important page and, alas, often the worst written. There are two culprits here and effective ways to cope with both of them.

First, the writer is usually straining too hard to say something terribly BIG and IMPORTANT about the thesis topic. The goal is worthy, but the aim is unrealistically high. The result is often a muddle of vague platitudes rather than a crisp, compelling introduction to the thesis. Want a familiar example? Listen to most graduation speakers. Their goal couldn’t be loftier: to say what education means and to tell an entire football stadium how to live the rest of their lives. The results are usually an avalanche of clichés and sodden prose.

The second culprit is bad timing. The opening and concluding paragraphs are usually written late in the game, after the rest of the thesis is finished and polished. There’s nothing wrong with writing these sections last. It’s usually the right approach since you need to know exactly what you are saying in the substantive middle sections of the thesis before you can introduce them effectively or draw together your findings. But having waited to write the opening and closing sections, you need to review and edit them several times to catch up. Otherwise, you’ll putting the most jagged prose in the most tender spots. Edit and polish your opening paragraphs with extra care. They should draw readers into the paper.

After you’ve done some extra polishing, I suggest a simple test for the introductory section. As an experiment, chop off the first few paragraphs. Let the paper begin on, say, paragraph 2 or even page 2. If you don’t lose much, or actually gain in clarity and pace, then you’ve got a problem.

There are two solutions. One is to start at this new spot, further into the text. After all, that’s where you finally gain traction on your subject. That works best in some cases, and we occasionally suggest it. The alternative, of course, is to write a new opening that doesn’t flop around, saying nothing.

What makes a good opening? Actually, they come in several flavors. One is an intriguing story about your topic. Another is a brief, compelling quote. When you run across them during your reading, set them aside for later use. Don’t be deterred from using them because they “don’t seem academic enough.” They’re fine as long as the rest of the paper doesn’t sound like you did your research in People magazine. The third, and most common, way to begin is by stating your main questions, followed by a brief comment about why they matter.

Whichever opening you choose, it should engage your readers and coax them to continue. Having done that, you should give them a general overview of the project—the main issues you will cover, the material you will use, and your thesis statement (that is, your basic approach to the topic). Finally, at the end of the introductory section, give your readers a brief road map, showing how the paper will unfold. How you do that depends on your topic but here are some general suggestions for phrase choice that may help:

  • This analysis will provide …
  • This paper analyzes the relationship between …
  • This paper presents an analysis of …
  • This paper will argue that …
  • This topic supports the argument that…
  • Research supports the opinion that …
  • This paper supports the opinion that …

Quotes, anecdotes, questions, examples, and broad statements—all of them can used successfully to write an introduction for a research paper. It’s instructive to see them in action, in the hands of skilled academic writers.

Let’s begin with David M. Kennedy’s superb history, Freedom from Fear: The American People in Depression and War, 1929–1945 . Kennedy begins each chapter with a quote, followed by his text. The quote above chapter 1 shows President Hoover speaking in 1928 about America’s golden future. The text below it begins with the stock market collapse of 1929. It is a riveting account of just how wrong Hoover was. The text about the Depression is stronger because it contrasts so starkly with the optimistic quotation.

“We in America today are nearer the final triumph over poverty than ever before in the history of any land.”—Herbert Hoover, August 11, 1928 Like an earthquake, the stock market crash of October 1929 cracked startlingly across the United States, the herald of a crisis that was to shake the American way of life to its foundations. The events of the ensuing decade opened a fissure across the landscape of American history no less gaping than that opened by the volley on Lexington Common in April 1775 or by the bombardment of Sumter on another April four score and six years later. The ratcheting ticker machines in the autumn of 1929 did not merely record avalanching stock prices. In time they came also to symbolize the end of an era. (David M. Kennedy, Freedom from Fear: The American People in Depression and War, 1929–1945 . New York: Oxford University Press, 1999, p. 10)

Kennedy has exciting, wrenching material to work with. John Mueller faces the exact opposite problem. In Retreat from Doomsday: The Obsolescence of Major War , he is trying to explain why Great Powers have suddenly stopped fighting each other. For centuries they made war on each other with devastating regularity, killing millions in the process. But now, Mueller thinks, they have not just paused; they have stopped permanently. He is literally trying to explain why “nothing is happening now.” That may be an exciting topic intellectually, it may have great practical significance, but “nothing happened” is not a very promising subject for an exciting opening paragraph. Mueller manages to make it exciting and, at the same time, shows why it matters so much. Here’s his opening, aptly entitled “History’s Greatest Nonevent”:

On May 15, 1984, the major countries of the developed world had managed to remain at peace with each other for the longest continuous stretch of time since the days of the Roman Empire. If a significant battle in a war had been fought on that day, the press would have bristled with it. As usual, however, a landmark crossing in the history of peace caused no stir: the most prominent story in the New York Times that day concerned the saga of a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest. This book seeks to develop an explanation for what is probably the greatest nonevent in human history. (John Mueller, Retreat from Doomsday: The Obsolescence of Major War . New York: Basic Books, 1989, p. 3)

In the space of a few sentences, Mueller sets up his puzzle and reveals its profound human significance. At the same time, he shows just how easy it is to miss this milestone in the buzz of daily events. Notice how concretely he does that. He doesn’t just say that the New York Times ignored this record setting peace. He offers telling details about what they covered instead: “a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest.” Likewise, David Kennedy immediately entangles us in concrete events: the stunning stock market crash of 1929. These are powerful openings that capture readers’ interests, establish puzzles, and launch narratives.

Sociologist James Coleman begins in a completely different way, by posing the basic questions he will study. His ambitious book, Foundations of Social Theory , develops a comprehensive theory of social life, so it is entirely appropriate for him to begin with some major questions. But he could just as easily have begun with a compelling story or anecdote. He includes many of them elsewhere in his book. His choice for the opening, though, is to state his major themes plainly and frame them as a paradox. Sociologists, he says, are interested in aggregate behavior—how people act in groups, organizations, or large numbers—yet they mostly examine individuals:

A central problem in social science is that of accounting for the function of some kind of social system. Yet in most social research, observations are not made on the system as a whole, but on some part of it. In fact, the natural unit of observation is the individual person…  This has led to a widening gap between theory and research… (James S. Coleman, Foundations of Social Theory . Cambridge, MA: Harvard University Press, 1990, pp. 1–2)

After expanding on this point, Coleman explains that he will not try to remedy the problem by looking solely at groups or aggregate-level data. That’s a false solution, he says, because aggregates don’t act; individuals do. So the real problem is to show the links between individual actions and aggregate outcomes, between the micro and the macro.

The major problem for explanations of system behavior based on actions and orientations at a level below that of the system [in this case, on individual-level actions] is that of moving from the lower level to the system level. This has been called the micro-to-macro problem, and it is pervasive throughout the social sciences. (Coleman, Foundations of Social Theory , p. 6)

Explaining how to deal with this “micro-to-macro problem” is the central issue of Coleman’s book, and he announces it at the beginning.

Coleman’s theory-driven opening stands at the opposite end of the spectrum from engaging stories or anecdotes, which are designed to lure the reader into the narrative and ease the path to a more analytic treatment later in the text. Take, for example, the opening sentences of Robert L. Herbert’s sweeping study Impressionism: Art, Leisure, and Parisian Society : “When Henry Tuckerman came to Paris in 1867, one of the thousands of Americans attracted there by the huge international exposition, he was bowled over by the extraordinary changes since his previous visit twenty years before.” (Robert L. Herbert, Impressionism: Art, Leisure, and Parisian Society . New Haven, CT: Yale University Press, 1988, p. 1.) Herbert fills in the evocative details to set the stage for his analysis of the emerging Impressionist art movement and its connection to Parisian society and leisure in this period.

David Bromwich writes about Wordsworth, a poet so familiar to students of English literature that it is hard to see him afresh, before his great achievements, when he was just a young outsider starting to write. To draw us into Wordsworth’s early work, Bromwich wants us to set aside our entrenched images of the famous mature poet and see him as he was in the 1790s, as a beginning writer on the margins of society. He accomplishes this ambitious task in the opening sentences of Disowned by Memory: Wordsworth’s Poetry of the 1790s :

Wordsworth turned to poetry after the revolution to remind himself that he was still a human being. It was a curious solution, to a difficulty many would not have felt. The whole interest of his predicament is that he did feel it. Yet Wordsworth is now so established an eminence—his name so firmly fixed with readers as a moralist of self-trust emanating from complete self-security—that it may seem perverse to imagine him as a criminal seeking expiation. Still, that is a picture we get from The Borderers and, at a longer distance, from “Tintern Abbey.” (David Bromwich, Disowned by Memory: Wordsworth’s Poetry of the 1790s . Chicago: University of Chicago Press, 1998, p. 1)

That’s a wonderful opening! Look at how much Bromwich accomplishes in just a few words. He not only prepares the way for analyzing Wordsworth’s early poetry; he juxtaposes the anguished young man who wrote it to the self-confident, distinguished figure he became—the eminent man we can’t help remembering as we read his early poetry.

Let us highlight a couple of other points in this passage because they illustrate some intelligent writing choices. First, look at the odd comma in this sentence: “It was a curious solution, to a difficulty many would not have felt.” Any standard grammar book would say that comma is wrong and should be omitted. Why did Bromwich insert it? Because he’s a fine writer, thinking of his sentence rhythm and the point he wants to make. The comma does exactly what it should. It makes us pause, breaking the sentence into two parts, each with an interesting point. One is that Wordsworth felt a difficulty others would not have; the other is that he solved it in a distinctive way. It would be easy for readers to glide over this double message, so Bromwich has inserted a speed bump to slow us down. Most of the time, you should follow grammatical rules, like those about commas, but you should bend them when it serves a good purpose. That’s what the writer does here.

The second small point is the phrase “after the revolution” in the first sentence: “Wordsworth turned to poetry after the revolution to remind himself that he was still a human being.” Why doesn’t Bromwich say “after the French Revolution”? Because he has judged his book’s audience. He is writing for specialists who already know which revolution is reverberating through English life in the 1790s. It is the French Revolution, not the earlier loss of the American colonies. If Bromwich were writing for a much broader audience—say, the New York Times Book Review—he would probably insert the extra word to avoid confusion.

The message “Know your audience” applies to all writers. Don’t talk down to them by assuming they can’t get dressed in the morning. Don’t strut around showing off your book learnin’ by tossing in arcane facts and esoteric language for its own sake. Neither will win over readers.

Bromwich, Herbert, and Coleman open their works in different ways, but their choices work well for their different texts. Your task is to decide what kind of opening will work best for yours. Don’t let that happen by default, by grabbing the first idea you happen upon. Consider a couple of different ways of opening your thesis and then choose the one you prefer. Give yourself some options, think them over, then make an informed choice.

Whether you begin with a story, puzzle, or broad statement, the next part of the introduction should pose your main questions and establish your argument. This is your thesis statement—your viewpoint along with the supporting reasons and evidence. It should be articulated plainly so readers understand full well what your paper is about and what it will argue.

After that, give your readers a road map of what’s to come. That’s normally done at the end of the introductory section (or, in a book, at the end of the introductory chapter). Here’s John J. Mearsheimer presenting such a road map in The Tragedy of Great Power Politics . He not only tells us the order of upcoming chapters, he explains why he’s chosen that order and which chapters are most important:

The Plan of the Book The rest of the chapters in this book are concerned mainly with answering the six big questions about power which I identified earlier. Chapter 2, which is probably the most important chapter in the book, lays out my theory of why states compete for power and why they pursue hegemony. In Chapters 3 and 4, I define power and explain how to measure it. I do this in order to lay the groundwork for testing my theory… (John J. Mearsheimer, The Tragedy of Great Power Politics . New York: W. W. Norton, 2001, p. 27)

As this excerpt makes clear, Mearsheimer has already laid out his “six big questions” in the introduction. Now he’s showing us the path ahead, the path to answering those questions.

At the end of the introduction, give your readers a road map of what’s to come. Tell them what the upcoming sections will be and why they are arranged in this particular order.

After having written your introduction it’s time to move to the biggest part: body of a research paper.

The Three-Paragraph Introduction: An Alternative to the Research Paper

Three Paragraph Introduction: An alternative to writing a research paper

Mark Giordano

July 10, 2017

One goal of my interdisciplinary (but primarily social and natural science based) freshman proseminar is to develop the skills to identify a research question. A second goal is to help the students master college level writing skills. I have found that meeting these goals through the assignment of a traditional research paper is problematic for two reasons. First, students struggle to understand the difference between identifying a research gap and constructing a paper to fill the gap (e.g. are the environmental impacts of dams always negative?) and constructing a paper to argue a point (e.g. we should build fewer dams), let alone actually do the research. Second, even if formats for structuring a research paper are given, students often struggle with logical flows within and between paragraphs and sections. Third, it is problematic for students to learn from feedback unless they have opportunities to revise their papers at least once and preferably more times. Multiple revision is logistically difficult given the lengths of traditional papers and the nature of the semester.

To meet my class content goals and partly address these issues around writing, I created a shorter, iterative research and writing assignment that focuses primarily on setting up a research paper, rather than writing the whole paper. In essence, the core of the assignment is to write just a three paragraph introduction. While the assignment is backed up with two, 4-5 page “content” papers, they are designed primarily to help students engage with and mentally organize content rather than as writing assignments per se. In terms of writing, my feedback to students, their revisions and my grading are focused primarily on the 3 paragraph introduction.

The steps I follow to implement the assignment are:

  • Relatively early in the semester, students are given background and instructions to the assignment, though there is nothing due for multiple weeks. The instructions are along these lines:

“A good introduction to a research paper can be as short as 3 paragraphs. It requires convincing people that your issue is important (paragraph 1), explaining what information gaps exist (paragraph 2), and demonstrating that your paper will at least partially fill one or more of those gaps and perhaps what your research found (paragraph 3). Writing paragraph 1 requires you to understand the context of your research. Writing paragraph 2 requires understanding the literature that has already been published. More explanation and discussion will occur over the course of the semester, but for now note that you will be asked to write and rewrite the paragraphs of your introduction as we move through the semester. Rewriting (again and again) is the key to a good paper.”

Over the early weeks of the semester we examine how the introductions of the academic papers we read in class are structured. Included in these readings are papers I wrote. We discuss how the papers conform or not to our in class discussions of what is needed in a good introduction.

  • Student decides on general topic half way through the semester and turn in a paper title. We discuss everyone’s titles to draw out issues and share ideas.
  • Students write a one paragraph introduction to their research paper as well as a 4-5 page background paper, with citations, that provides the context for their paragraph. The purpose of the background paper is to ensure that students are delving into the subject matter.
  • Professor gives detailed feedback on the paragraph. The professor’s comments on the background paper are focused primarily on subject matter, though more general comments may be given on writing.
  • Students write a second 4-5 page paper that examines the published literature on their subject and establishes a question that the literature has yet to answer. The paper must include 15-20 academic citations to ensure that the students have engaged reasonably well with the literature. Based on this background paper, students write the second paragraph of their introduction. Students turn in turn in a revised first paragraph, their new second paragraph, and the new 4-5 page background paper.
  • Professor gives detailed feedback on the first two paragraphs of the introduction. More general writing comments are given on the background paper. Substantial comments are often given on the content of the background paper as students struggle to understand what a research question really is and how one establishes such a question.
  • After students receive feedback, at least one and often more discussions occur in the following classes on what it means to establish a research question.
  • Based on feedback, students rewrite their second paragraph, often after doing substantial new literature review. Students also write a new third paragraph in which they suggest the methods they would use to answer their research question and hypothesize their results. As the students do not actually do the research, this paragraph is more of a fun assignment in which they can use their imagination. Students turn in revisions of their first two paragraphs plus their new third paragraph.
  • Professor gives detailed comments on the 3 paragraph introduction.
  • As the paper is due before the end of the semester, one or more additional class discussions occur on the overall writing experience.
  • In some iterations of the class, students also peer review each others papers.

In using this format over the past 3 years, I have found the following advantages and disadvantages:

  • The short format allows me to carefully read every word and sentence and provide detailed comments on what worked for the student, what didn’t, and what should be considered in the future to improve the work.
  • The iterative process allows (i.e. forces) students to carefully consider my comments and make changes based on them. I find this a major improvement over the typical process in which I write on the papers and am not sure that the comments are even read. The iterative process also encourages in class discussions on both writing and content.
  • I set the assignment up in part to to emphasis the difficult to grasp concept of a research question. I find that focusing on the question through short iterative writing, rather than jumping into an attempt at an answer, helps students grasp the idea. In my experience, the importance of purposefully developing this skill of crafting a research question cannot be underestimated. As an example, many students in my senior seminars and those applying to do honors theses do not know what a research question is. The assignment could of course be changed to emphasis other content areas.
  • Because the students spend so much time on each paragraph based on feedback and discussion, and because they have carefully thought through an actual research question, they often use their work from my class in their applications for research-based scholarships and other opportunities. In some cases they use their actual work from my class in their applications. In others, they choose new topics but model their proposals on their 3 paragraph introductions.
  • While I do grade each iteration of the assignment, I have found it difficult to develop rubrics to fairly differentiate students and their efforts, especially as the papers improve over the course of the semester.

INSTRUCTIONS FOR THE ASSIGNMENT PROVIDED TO STUDENTS IN THE CLASS SYLLABUS

Research paper introduction and lit review

The main product for the class is the introduction to a research paper and the supporting literature review. YOU DO NOT ACTUALLY DO THE RESEARCH OR WRITE A FULL PAPER. The product will be accomplished through 6 relatively short, interconnected writing assignments. Due dates for each assignment are given in the schedule. The assignments have three main goals beyond learning about water. The first is to help you learn the difference between research and reporting/advocacy/argument. The second is to help you learn how to construct a strong opening for the many papers you will have to write at Georgetown and the rest of your life. The third is to learn how to do a literature review either for a research paper or to establish the evidence base for decision making.

A good introduction to a research paper can be as short as 3 paragraphs. It requires convincing people that your issue is important (paragraph 1), explaining what information gaps are still out there (paragraph 2), and demonstrating that your paper will at least partially fill one or more of those gaps (paragraph 3). Writing paragraph 2 requires understanding the literature that has already been published. More explanation and discussion will occur over the course of the semester, but for now note that you will be asked to write and rewrite the paragraphs of your introduction as we move through the semester. Rewriting (again and again) is the key to a good paper.

The assignment has 4 main goals:

  • Learn more indepth information about an aspect of the class that interests you,
  • Learning the difference between research and reporting/advocacy/argument.
  • Learning how to construct a strong opening for any academic paper
  • Learning how to conduct a literature review either for a research paper or to establish the evidence base for decision making.

All assignment must be turned into Canvas.

Part 1: Paper Title (0%) Provide a title for you paper in the form of a question. You can change the title every time you turn in your paper. While you get no points for doing this, you still lose 1% of your total grade for everyday the title is late.

Part 2: Background to the topic (5%) You need to make sure your topic is interesting andrite a paper of approximately 4-5 pages describing what your topic is and why the reader should care about it. You must cite at least 10 works. Citations may come from academic literature, but for this part of the assignment they may also come from popular press.

Part 2 : First paragraph to the introduction (10%) What is the paper about and why is it worth reading? Writing a good introductory paragraph requires an ability to convey an overall understanding of the issues and how they fit into the reader’s world. It establishes whether the reader wants to continue reading your paper and sets the stage for the work you will do. The introductory paragraph may include citations from popular press, academic articles, or both.

Part 5: First two paragraphs of your paper 5%

Part 6: Full introduction including paragraph on how you will fill the gap (3 paragraphs) 5%

All assignments must be emailed to me by 8am on the day they are due. Your file must be named INAF100_LASTNAME_#, where LASTNAME represents your family name and # represents the assignment number

How to do citations in this class

Like this: “Giordano (2015) believe that ….,”

or like this: “Some researchers (Giordano, 2105; Byman, 2016) believe that…”

In your bibliography, for all academic articles, use one of the automatic formats provided by GoogleScholar, e.g.:

Wolf, A. T., Yoffe, S. B., & Giordano, M. (2003). International waters: Identifying basins at risk. Water policy, 5(1), 29-60.

Do not use footnotes or endnotes to cite sources.

If you do not cite as instructed, your assignment is automatically reduced by one letter grade.

Part 4: Justifying the research question/gap (2-4 pages) 15%

Part 3: Revised first paragraph to the introduction, second paragraph to the introduction, and literature review (20%)

A research paper requires an original research question or the establishment of a knowledge gap that needs to be filled. To be credible, you must convince the reader that you are aware of what is already known by doing a literature review and articulating it to the reader. For this class, the literature review must include AT LEAST 20 ACADEMIC articles. Can you include non-academic articles? YES. Do you still need 20 academic articles? YES.

You must organize your literature review using a typology (method for classification) that you create. In other words, don’t discuss the articles one after the other. Instead, organize the ideas in each article according to concepts you define as important. Don’t write, “Johnson (2015) says this. Smith (2013) says that.” Instead write, “The literature on water and conflict is divided into two camps. The first camp (Jones, 2013; Smith, 2015) highlights that increased scarcity will inevitably lead to increased social tensions. The second camp (Wight, 2010; Billinglea, 2012) highlights that increased scarcity induces the creation of new institutions to mitigate scarcity’s impact.” You might then explain specifics of some of the authors, but the organization (typology) is generally by concept, not author.

You must define the concepts (typologies) in the way that makes sense to your project and the academic fields from which you are drawing. For this assignment, the typology should be clearly labeled by creating sub-headings in the literature review section. You must also provide a summary of the literature review at the end of the section that leads the reader to understand what the research question/knowledge gap is that your project (if you were to actually do it) would attempt to address.

This assignment should be structured like this:

Title (edited version of what you already produced for Parts I and II)

Introduction

First Paragraph (edited version of what you already produced for Part II)

Second Paragraph (summarizes for the reader the knowledge gap that you identify in your literature review and that your research would fill if you were to actually do it).

Literature Review

Introductory paragraph/section

Sub-heading 1

Sub-heading 2

Sub-heading 3….

Summary paragraph/section

How long should a literature review be? There is no clear answer, but probably 5 or so pages. A literature review in a journal like Science might be one or two paragraphs. A literature review for a PhD thesis might be one or more chapters.

It is important to note that the literature about your topic does not have to be specifically about your PARTICULAR topic. Good research draws on theory, not just subjects. If you want to write a paper on whether Bangladesh and India are going to fight over the Ganges, you don’t want to only look at the literature on India, Bangladesh and the Ganges. You might also, for example, want to consider the literature on theories of international conflict and then try to apply those to the case of India and Bangladesh and their shared river.

Part 4: Full introduction and literature review (20%)

Detailing the Writing of Scientific Manuscripts: 25-30 Paragraphs

In their professional practices, physicians often face unexpected situations or chance on innovative proposals and ideas. As a result of their training and competence, they usually come up with hypotheses to be tested and research is conducted. This research is completed and their results submitted for presentations at conferences as free communications. Nevertheless, the realization of this creative process is only complete when a scientific manuscript is published in a journal. At this ultimate stage, most efforts seem not be brought to a standstill 1 , 2 . There are several reasons why scholars, interns, residents, graduate students and even experienced physicians may find it difficult to move forward from congress' abstracts to full manuscripts published in journals. However, the most significant hindrance rests with the difficulty writing the mere 25-30 paragraphs of an original manuscript. Many freeze and give up in front of a blank paper or a blinking cursor on a blank word processor's page on the monitor screen. In the previous manuscript 3 , we analyzed and suggested improvements to the process of peer review. In this point of view, we propose a practical strategy to systematize the writing of scientific paragraphs, aiming to simplify the task of scientific writing. This way, our intent is to increase the rate of publication of full manuscripts based on several outstanding abstracts presented annually at major medical conferences, and facilitate the currently overburdened process of peer review.

The format of scientific communication has been evolving greatly over the centuries 4 - 7 , making reading more objective and standardized. One of the important tools in this process is the IMRaD format 4 , 5 , 7 , an acronym derived from the initials of the main sections of a manuscript - introduction, methods, results and discussion. Throughout the twentieth century, the IMRaD format has been increasingly applied, accounting for about 10% of the manuscripts in the 1950s, being dominant in the 1960s, and reaching 80% in the 1970s 7 . Presently, IMRad is the format recommended and adopted by the main medical journals all over the world, including the ABC ( Arquivos Brasileiros de Cardiologia ).

In addition to the IMRaD format, original manuscripts submitted for publication should meet specific standards and rules of each journal. Although a fairly uniform pattern tends to prevail, there are differences that should be observed at the time of writing. For instance, the number of words is limited to 4,500 in ABC and 5,000 in JACC, including text and references. Considering that the references are usually limited to 30-40, and have around 1,000 words, circa 3,500-4,000 are left for the text's body, i.e., to be used in the 25-30 paragraphs of IMRaD, representing about 130 words each.

In the pursuit for evidence and objective data, as a convenience sample, all original manuscripts published in the January 2012 and 2013 editions of ABC and JACC journals have been analyzed (the first two numbers of these months for the latter). There was a fairly clear trend about the total number of paragraphs and distribution of paragraphs in four sections of the IMRaD of a manuscript. For the 20 ABC's manuscripts and 34 JACC's ones, the average number of paragraphs was 28.9 and 28.2 (p = 0.703), respectively, with 1/3 of them having 25-30 paragraphs, and 57% of the total manuscripts having overall 22-33 paragraphs. This relative constancy should be observed and highlighted, considering that the topics and areas covered, as well as the background and the nationality of the authors, are quite different. Thus, this confirms the assumption that there is a basic format to be followed for an effective publication.

Figure 1 illustrates the distribution of paragraphs for the various IMRaD sections in the two journals analyzed. Although there is some variability among the manuscripts, the introduction is clearly a section with fewer paragraphs (p < 0.001), while the remaining sections are somewhat balanced (p > 0.05), especially for original manuscripts of JACC, in which the sections of methods, results and discussion tend to have eight to nine paragraphs. When the distributions of paragraphs between ABC and JACC are compared, introductions and discussions tend to have more paragraphs in ABC than in JACC, respectively, 3.8 versus 2.4 (p < 0.01) and 10.4 versus 8.8 (p = 0.04).

Comparative analysis on the number of paragraphs per section of IMRaD for original manuscripts between Arquivos Brasileiros de Cardiologia (Arq Bras Cardiol) and Journal of The American College of Cardiology (JACC). I: introduction; M: methods; R: results; D: discussion. The box-plot represents median values, the first and third quartiles and 5 th and 95 th percentiles.*Significant difference between the number of paragraphs of the two journals for this section.

Based on these results, in our personal experience as authors of original manuscripts and according to other authors' opinions 4 , 8 - 10 , a simple content model may be proposed within the IMRaD format, taking 25-30 paragraphs as standard for an original manuscript. For practical purposes, one page is considered one page in a word processor, with conventional margins and with a 1.5 line spacing and font size 11.

Unfolding the sections

Introduction: 1 page (ideally), maximum 400 words over 1-4 paragraphs (ideally 3) - some journals restrict this to 350 words (E.g.: ABC); 5-10 references.

Methods: 2-3 pages (possibly higher in experiments resorting to innovative methods or plenty of techniques or sophisticated statistics) - not exceeding 750 words over 6 9 paragraphs; 5-15 references

Results: 2-3 pages of text, figures and tables, as strictly necessary; not exceeding 1,000 words over 4-9 paragraphs; usually without references.

Discussion: 3-4 pages of text; this is usually the most extensive part of the manuscript relating to word count 4 , 8 - 10 , with 1,000-1,500 words distributed over up to 10 paragraphs; including a conclusion paragraph, although some journals consider the latter another text section. The discussion usually has 10-20 references, with some of them possibly appearing in previous text sections.

Unfolding the paragraphs

Introduction.

1. Problem - what is known?

2. Contextualization *

3. Knowledge gap - what is not known?

4. Definition and purpose of the study - what will be studied and the hypothesis or objective; preferably not including results or conclusions *

5. Population and sample - inclusion and/or exclusion criteria; reference to the informed consent form and approval by the ethics committee

6. Population and sample II - description of specific sampling subgroups or, when necessary, in-depth detailing of procedures connected to follow-up and losses *

7. Main methods - most important variable or procedure

8. Main methods II - unfolding the paragraph above *

9. Secondary methods - less important variables

10. Study protocol - detailing of what has been done and how it has been done

11. Study protocol II - additional data when necessary and justified *

12. Statistical analysis - descriptive and inferential methods

13. Statistical analysis II - software and significance level *

14. General data - description of sample and information about the patient selection flow and actual performance of the study

15. Main results - the most important variables

16. Main results II - additional results and other analyzes of the most important variables *

17. Secondary results - the other study variables

18. Secondary results II - additional results of variables or the interrelation or interaction between them *

19. Secondary results III - additional results of variables or the interrelation or interaction between them *

20. Other results and analysis carried out in the study *

21. The problem and the study's "original" proposal - discussing again the study's problem

22. Interpretation of the main result - meaning of what has been found

23. Comparison with the literature - how this result confirms previous data

24. Further comparison with the literature * - exploring methodological or mechanistic differences

25. The main result's contribution to knowledge - the "novelty" or main message or contribution of the research to the current state-of-the-art

26. Interpretation of secondary results - what these results inform or mean

27. Interpretation of secondary results II *

28. Comparison of this study with previous ones - the contribution and developments in this study for the area's knowledge

29. Limits of the study - strengths and weaknesses; the weaknesses and methodological problems of the study and, especially, how these limitations may hinder the practical application of the results and their interpretations. The strengths of the study may also be stressed, possibilities may be pointed out, as well as issues to be further researched - other knowledge gaps

30. Conclusions and implications - this represents a synthesis of the study, usually answering the hypothesis reported in the final paragraph of the introductory section, solving the study objective.

A rather practical observation is that the writing of paragraphs does not need to follow the order of sections or, even, the several paragraphs making up the given section. In practice, most of the experienced authors start with the methods and results, hence following to the discussion, and only then proceeding to the introduction. The title is typically their last concern.

Grounded on the practical strategy presented in this point of view, in keeping with the IMRaD format, we may assert that potential authors will deal better with blinking cursors on the word processor and will deal easily and objectively with the final stage of transforming an outstanding communication at a conference into an excellent original manuscript. This will allow a much larger audience to benefit from their findings and interpretations, forever.

* These paragraphs are optional, and often the contents can se incorporated into the previous paragraph(s).

9.4 Writing Introductory and Concluding Paragraphs

Learning objectives.

  • Recognize the importance of strong introductory and concluding paragraphs.
  • Learn to engage the reader immediately with the introductory paragraph.
  • Practice concluding your essays in a more memorable way.

Picture your introduction as a storefront window: You have a certain amount of space to attract your customers (readers) to your goods (subject) and bring them inside your store (discussion). Once you have enticed them with something intriguing, you then point them in a specific direction and try to make the sale (convince them to accept your thesis).

Your introduction is an invitation to your readers to consider what you have to say and then to follow your train of thought as you expand upon your thesis statement.

An introduction serves the following purposes:

  • Establishes your voice and tone, or your attitude, toward the subject
  • Introduces the general topic of the essay
  • States the thesis that will be supported in the body paragraphs

First impressions are crucial and can leave lasting effects in your reader’s mind, which is why the introduction is so important to your essay. If your introductory paragraph is dull or disjointed, your reader probably will not have much interest in continuing with the essay.

Attracting Interest in Your Introductory Paragraph

Your introduction should begin with an engaging statement devised to provoke your readers’ interest. In the next few sentences, introduce them to your topic by stating general facts or ideas about the subject. As you move deeper into your introduction, you gradually narrow the focus, moving closer to your thesis. Moving smoothly and logically from your introductory remarks to your thesis statement can be achieved using a funnel technique , as illustrated in the diagram in Figure 9.1 “Funnel Technique” .

Figure 9.1 Funnel Technique

image

On a separate sheet of paper, jot down a few general remarks that you can make about the topic for which you formed a thesis in Section 9.1 “Developing a Strong, Clear Thesis Statement” .

Immediately capturing your readers’ interest increases the chances of having them read what you are about to discuss. You can garner curiosity for your essay in a number of ways. Try to get your readers personally involved by doing any of the following:

  • Appealing to their emotions
  • Using logic
  • Beginning with a provocative question or opinion
  • Opening with a startling statistic or surprising fact
  • Raising a question or series of questions
  • Presenting an explanation or rationalization for your essay
  • Opening with a relevant quotation or incident
  • Opening with a striking image
  • Including a personal anecdote

Remember that your diction, or word choice, while always important, is most crucial in your introductory paragraph. Boring diction could extinguish any desire a person might have to read through your discussion. Choose words that create images or express action. For more information on diction, see Chapter 4 “Working with Words: Which Word Is Right?” .

In Chapter 8 “The Writing Process: How Do I Begin?” , you followed Mariah as she moved through the writing process. In this chapter, Mariah writes her introduction and conclusion for the same essay. Mariah incorporates some of the introductory elements into her introductory paragraph, which she previously outlined in Chapter 8 “The Writing Process: How Do I Begin?” . Her thesis statement is underlined.

If you have trouble coming up with a provocative statement for your opening, it is a good idea to use a relevant, attention-grabbing quote about your topic. Use a search engine to find statements made by historical or significant figures about your subject.

Writing at Work

In your job field, you may be required to write a speech for an event, such as an awards banquet or a dedication ceremony. The introduction of a speech is similar to an essay because you have a limited amount of space to attract your audience’s attention. Using the same techniques, such as a provocative quote or an interesting statistic, is an effective way to engage your listeners. Using the funnel approach also introduces your audience to your topic and then presents your main idea in a logical manner.

Reread each sentence in Mariah’s introductory paragraph. Indicate which techniques she used and comment on how each sentence is designed to attract her readers’ interest.

Writing a Conclusion

It is not unusual to want to rush when you approach your conclusion, and even experienced writers may fade. But what good writers remember is that it is vital to put just as much attention into the conclusion as in the rest of the essay. After all, a hasty ending can undermine an otherwise strong essay.

A conclusion that does not correspond to the rest of your essay, has loose ends, or is unorganized can unsettle your readers and raise doubts about the entire essay. However, if you have worked hard to write the introduction and body, your conclusion can often be the most logical part to compose.

The Anatomy of a Strong Conclusion

Keep in mind that the ideas in your conclusion must conform to the rest of your essay. In order to tie these components together, restate your thesis at the beginning of your conclusion. This helps you assemble, in an orderly fashion, all the information you have explained in the body. Repeating your thesis reminds your readers of the major arguments you have been trying to prove and also indicates that your essay is drawing to a close. A strong conclusion also reviews your main points and emphasizes the importance of the topic.

The construction of the conclusion is similar to the introduction, in which you make general introductory statements and then present your thesis. The difference is that in the conclusion you first paraphrase , or state in different words, your thesis and then follow up with general concluding remarks. These sentences should progressively broaden the focus of your thesis and maneuver your readers out of the essay.

Many writers like to end their essays with a final emphatic statement. This strong closing statement will cause your readers to continue thinking about the implications of your essay; it will make your conclusion, and thus your essay, more memorable. Another powerful technique is to challenge your readers to make a change in either their thoughts or their actions. Challenging your readers to see the subject through new eyes is a powerful way to ease yourself and your readers out of the essay.

When closing your essay, do not expressly state that you are drawing to a close. Relying on statements such as in conclusion , it is clear that , as you can see , or in summation is unnecessary and can be considered trite.

It is wise to avoid doing any of the following in your conclusion:

  • Introducing new material
  • Contradicting your thesis
  • Changing your thesis
  • Using apologies or disclaimers

Introducing new material in your conclusion has an unsettling effect on your reader. When you raise new points, you make your reader want more information, which you could not possibly provide in the limited space of your final paragraph.

Contradicting or changing your thesis statement causes your readers to think that you do not actually have a conviction about your topic. After all, you have spent several paragraphs adhering to a singular point of view. When you change sides or open up your point of view in the conclusion, your reader becomes less inclined to believe your original argument.

By apologizing for your opinion or stating that you know it is tough to digest, you are in fact admitting that even you know what you have discussed is irrelevant or unconvincing. You do not want your readers to feel this way. Effective writers stand by their thesis statement and do not stray from it.

On a separate sheet of a paper, restate your thesis from Note 9.52 “Exercise 2” of this section and then make some general concluding remarks. Next, compose a final emphatic statement. Finally, incorporate what you have written into a strong conclusion paragraph for your essay.

Collaboration

Please share with a classmate and compare your answers

Mariah incorporates some of these pointers into her conclusion. She has paraphrased her thesis statement in the first sentence.

Make sure your essay is balanced by not having an excessively long or short introduction or conclusion. Check that they match each other in length as closely as possible, and try to mirror the formula you used in each. Parallelism strengthens the message of your essay.

On the job you will sometimes give oral presentations based on research you have conducted. A concluding statement to an oral report contains the same elements as a written conclusion. You should wrap up your presentation by restating the purpose of the presentation, reviewing its main points, and emphasizing the importance of the material you presented. A strong conclusion will leave a lasting impression on your audience.

Key Takeaways

  • A strong opening captures your readers’ interest and introduces them to your topic before you present your thesis statement.
  • An introduction should restate your thesis, review your main points, and emphasize the importance of the topic.
  • The funnel technique to writing the introduction begins with generalities and gradually narrows your focus until you present your thesis.
  • A good introduction engages people’s emotions or logic, questions or explains the subject, or provides a striking image or quotation.
  • Carefully chosen diction in both the introduction and conclusion prevents any confusing or boring ideas.
  • A conclusion that does not connect to the rest of the essay can diminish the effect of your paper.
  • The conclusion should remain true to your thesis statement. It is best to avoid changing your tone or your main idea and avoid introducing any new material.
  • Closing with a final emphatic statement provides closure for your readers and makes your essay more memorable.

A paragraph is a group of related sentences that support one main idea. In general, paragraphs consist of three parts: the topic sentence, body sentences, and the concluding or the bridge sentence to the next paragraph or section. Paragraphs show where the subdivisions of a research paper begin and end and, thus, help the reader see the organization of the essay and grasp its main points.

Arnaudet, Martin L. and Mary Ellen Barrett. Paragraph Development: A Guide for Students of English . 2nd edition. Englewood Cliffs, NJ: Prentice Hall Regents, 1990.

Importance of Constructing Good Paragraphs

Paragraphs are the building blocks of papers . Without well-written paragraphs that flow logically from one idea to the next and that inform and help support in some meaningful way the central research problem being investigated, your paper will not be viewed as credible and, well, you'll probably receive a poor grade.

Here are some suggestions for troubleshooting common problems associated with developing paragraphs:

1.  The paragraph has no controlling idea . Imagine each paragraph as having three general layers of text. The core content is in the middle. It includes all the evidence you need to make the point. However, this evidence needs to be introduced by a topic sentence in some way or your readers don't know what to do with all the evidence you have given them. Therefore, the beginning of the paragraph explains the controlling idea of the paragraph. The last part of the paragraph tells the reader how the paragraph relates to the broader argument and often provides a transition to the next idea. Once you have mastered the use of topic sentences, you may decide that the topic sentence for a particular paragraph really should not be the first sentence of the paragraph. This is fine—the topic sentence can actually go at the beginning, middle, or end of a paragraph; what's important is that it is there to inform readers what the main idea of the paragraph is and how it relates back to the broader thesis of your paper.

2.  The paragraph has more than one controlling idea . This is the most common reason why a paragraph is too long. If a paragraph is more than a page long, it likely contains more than one controlling idea. In this case, consider eliminating sentences that relate to the second idea, with the thought that maybe they don't really inform and help support the central research problem, or split the paragraph into two or more paragraphs, each with only one controlling idea.

3.  Transitions are needed within the paragraph . You are probably familiar with the idea that transitions may be needed between paragraphs or sections in a paper. Sometimes they are also helpful within the body of a single paragraph. Within a paragraph, transitions are often single words or short phrases that help to establish relationships between ideas and to create a logical progression of those ideas in a paragraph. This is especially true within paragraphs that discuss multiple examples or discuss complex ideas, issues, or concepts.

Centre for Applied Linguistics. University of Warwick.

Structure and Writing Style

I.  General Structure

Most paragraphs in an essay parallel the general three-part structure of each section of a research paper and, by extension, the overall research paper, with an introduction, a body that includes facts and analysis, and a conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating the meaning you intend to covey to the reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea. For long paragraphs, you may also want to include a bridge sentence that introduces the next paragraph or section of the paper. In some instances, the bridge sentence can be written in the form of a question. However, use this rhetorical device sparingly, otherwise, ending a lot of paragraphs with a question to lead into the next paragraph sounds cumbersome.

NOTE:   This general structure does not imply that you should not be creative in your writing. Arranging where each element goes in a paragraph can make a paper more engaging for the reader. However, do not be too creative in experimenting with the narrative flow of paragraphs. To do so may distract from the main arguments of your research and weaken the quality of your academic writing.

II.  Development and Organization

Before you can begin to determine what the composition of a particular paragraph will be, you must consider what is the most important idea that you are trying to convey to your reader. This is the "controlling idea," or the thesis statement from which you compose the remainder of the paragraph. In other words, your paragraphs should remind your reader that there is a recurrent relationship between your controlling idea and the information in each paragraph. The research problem functions like a seed from which your paper, and your ideas, will grow. The whole process of paragraph development is an organic one—a natural progression from a seed idea to a full-blown research study where there are direct, familial relationships in the paper between all of  your controlling ideas and the paragraphs which derive from them. The decision about what to put into your paragraphs begins with brainstorming about how you want to pursue the research problem . There are many techniques for brainstorming but, whichever one you choose, this stage of paragraph development cannot be skipped because it lays a foundation for developing a set of paragraphs [representing a section of your paper] that describes a specific element of your overall analysis. Each section is described further in this writing guide. Given these factors, every paragraph in a paper should be :

  • Unified —All of the sentences in a single paragraph should be related to a single controlling idea [often expressed in the topic sentence of the paragraph].
  • Clearly related to the research problem —The sentences should all refer to the central idea, or the thesis, of the paper.
  • Coherent —The sentences should be arranged in a logical manner and should follow a definite plan for development.
  • Well-developed —Every idea discussed in the paragraph should be adequately explained and supported through evidence and details that work together to explain the paragraph's controlling idea.

There are many different ways you can organize a paragraph . However, the organization you choose will depend on the controlling idea of the paragraph. Ways to organize a paragraph in academic writing include:

  • Narrative : Tell a story. Go chronologically, from start to finish.
  • Descriptive : Provide specific details about what something looks or feels like. Organize spatially, in order of appearance, or by topic.
  • Process : Explain step by step how something works. Perhaps follow a sequence—first, second, third.
  • Classification : Separate into groups or explain the various parts of a topic.
  • Illustrative : Give examples and explain how those examples prove your point.

Writing Tip

Coherence of Ideas is What Matters, Not Length!

Do not think of developing paragraphs in terms of their length. Length and appearance do not determine whether a part in your paper is a paragraph. It is the unity and coherence of ideas represented in a sentence or among sentences that constitutes to a good paragraph.

How Long Should the Introduction of a Research Paper Be? Data from 61,518 Examples

I analyzed a random sample of 61,518 full-text research papers, uploaded to PubMed Central between the years 2016 and 2021, in order to answer the questions:

What is the typical length of an introduction section? and which factors influence it?

I used the BioC API to download the data (see the References section below).

Here’s a summary of the key findings

1. The median introduction was 553 words long (equivalent to 21 sentences, or 4 paragraphs), and 90% of the introductions were between 245 and 1,245 words.

2. The introduction is the shortest section of the research paper (14.6% of the total word count), approximately half the length of other sections (Methods, Results, and Discussion).

3. The length of the introduction does not differ between review articles and original research articles .

4. The quality of the journal does not influence the length of the introduction section .

Overall length of the introduction section

Here’s a table that describes the length of an introduction in terms of words, sentences, and paragraphs:

From these data, we can conclude that most research papers have a 3 to 5 paragraph introductions (consisting of 15 to 28 sentences).

If you are interested, here’s the link to the PubMed article that had the longest introduction of 9,776 words, 426 sentences, and 196 paragraphs!

The introduction constitutes 14.6% of the total word count of a research paper, nearly half the length of other sections (Methods, Results, and Discussion) [source: How Long Should a Research Paper Be? ].

Length of the introduction for different article types

The following table shows the median word count of the introduction section for different study designs:

The data show no clear pattern since the introductions of review articles and original research articles have almost similar word counts. So we can conclude that there is no particular article type that requires a longer introduction section.

Length of the introduction in different journals

In order to study the influence of the journal quality on the length of the introduction, I ran a Poisson regression that models the introduction word count given the journal impact factor. Here’s the model output:

The model shows that a higher journal impact factor is associated with a longer introduction. Although statistically significant, this result is practically negligible since an increase of 1 unit in the journal impact factor is associated with an increase of only 0.8% in the introduction word count.

How to Write a Thesis or Dissertation Introduction

Published on September 7, 2022 by Tegan George and Shona McCombes. Revised on November 21, 2023.

The introduction is the first section of your thesis or dissertation , appearing right after the table of contents . Your introduction draws your reader in, setting the stage for your research with a clear focus, purpose, and direction on a relevant topic .

Your introduction should include:

Although your introduction kicks off your dissertation, it doesn’t have to be the first thing you write — in fact, it’s often one of the very last parts to be completed (just before your abstract ).

It’s a good idea to write a rough draft of your introduction as you begin your research, to help guide you. If you wrote a research proposal , consider using this as a template, as it contains many of the same elements. However, be sure to revise your introduction throughout the writing process, making sure it matches the content of your ensuing sections.

Prevent plagiarism. Run a free check.

Begin by introducing your dissertation topic and giving any necessary background information. It’s important to contextualize your research and generate interest. Aim to show why your topic is timely or important. You may want to mention a relevant news item, academic debate, or practical problem.

After a brief introduction to your general area of interest, narrow your focus and define the scope of your research.

You can narrow this down in many ways, such as by:

  • Geographical area
  • Time period
  • Demographics or communities
  • Themes or aspects of the topic

It’s essential to share your motivation for doing this research, as well as how it relates to existing work on your topic. Further, you should also mention what new insights you expect it will contribute.

Start by giving a brief overview of the current state of research. You should definitely cite the most relevant literature, but remember that you will conduct a more in-depth survey of relevant sources in the literature review section, so there’s no need to go too in-depth in the introduction.

Depending on your field, the importance of your research might focus on its practical application (e.g., in policy or management) or on advancing scholarly understanding of the topic (e.g., by developing theories or adding new empirical data). In many cases, it will do both.

Ultimately, your introduction should explain how your thesis or dissertation:

  • Helps solve a practical or theoretical problem
  • Addresses a gap in the literature
  • Builds on existing research
  • Proposes a new understanding of your topic

Perhaps the most important part of your introduction is your questions and objectives, as it sets up the expectations for the rest of your thesis or dissertation. How you formulate your research questions and research objectives will depend on your discipline, topic, and focus, but you should always clearly state the central aim of your research.

If your research aims to test hypotheses , you can formulate them here. Your introduction is also a good place for a conceptual framework that suggests relationships between variables .

  • Conduct surveys to collect data on students’ levels of knowledge, understanding, and positive/negative perceptions of government policy.
  • Determine whether attitudes to climate policy are associated with variables such as age, gender, region, and social class.
  • Conduct interviews to gain qualitative insights into students’ perspectives and actions in relation to climate policy.

To help guide your reader, end your introduction with an outline  of the structure of the thesis or dissertation to follow. Share a brief summary of each chapter, clearly showing how each contributes to your central aims. However, be careful to keep this overview concise: 1-2 sentences should be enough.

I. Introduction

Human language consists of a set of vowels and consonants which are combined to form words. During the speech production process, thoughts are converted into spoken utterances to convey a message. The appropriate words and their meanings are selected in the mental lexicon (Dell & Burger, 1997). This pre-verbal message is then grammatically coded, during which a syntactic representation of the utterance is built.

Speech, language, and voice disorders affect the vocal cords, nerves, muscles, and brain structures, which result in a distorted language reception or speech production (Sataloff & Hawkshaw, 2014). The symptoms vary from adding superfluous words and taking pauses to hoarseness of the voice, depending on the type of disorder (Dodd, 2005). However, distortions of the speech may also occur as a result of a disease that seems unrelated to speech, such as multiple sclerosis or chronic obstructive pulmonary disease.

This study aims to determine which acoustic parameters are suitable for the automatic detection of exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD) by investigating which aspects of speech differ between COPD patients and healthy speakers and which aspects differ between COPD patients in exacerbation and stable COPD patients.

The introduction of a research paper includes several key elements:

  • A hook to catch the reader’s interest
  • Relevant background on the topic
  • Details of your research problem

and your problem statement

  • A thesis statement or research question
  • Sometimes an overview of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

Research objectives describe what you intend your research project to accomplish.

They summarize the approach and purpose of the project and help to focus your research.

Your objectives should appear in the introduction of your research paper , at the end of your problem statement .

Scope of research is determined at the beginning of your research process , prior to the data collection stage. Sometimes called “scope of study,” your scope delineates what will and will not be covered in your project. It helps you focus your work and your time, ensuring that you’ll be able to achieve your goals and outcomes.

Defining a scope can be very useful in any research project, from a research proposal to a thesis or dissertation . A scope is needed for all types of research: quantitative , qualitative , and mixed methods .

To define your scope of research, consider the following:

  • Budget constraints or any specifics of grant funding
  • Your proposed timeline and duration
  • Specifics about your population of study, your proposed sample size , and the research methodology you’ll pursue
  • Any inclusion and exclusion criteria
  • Any anticipated control , extraneous , or confounding variables that could bias your research if not accounted for properly.

What Is an Introduction Paragraph? 

An introduction paragraph is the first paragraph of an essay , paper, or other type of academic writing. Argumentative essays , book reports, research papers, and even personal  essays are common types of writing that require an introduction paragraph. Whether you’re writing a research paper for a science course or an argumentative essay for English class , you’re going to have to write an intro paragraph. 

So what’s the purpose of an intro paragraph? As a reader’s first impression of your essay, the intro paragraph should introduce the topic of your paper. 

Your introduction will also state any claims, questions, or issues that your paper will focus on. This is commonly known as your paper’s thesis . This condenses the overall point of your paper into one or two short sentences that your reader can come back and reference later.

But intro paragraphs need to do a bit more than just introduce your topic. An intro paragraph is also supposed to grab your reader’s attention. The intro paragraph is your chance to provide just enough info and intrigue to make your reader say, “Hey, this topic sounds interesting. I think I’ll keep reading this essay!” That can help your essay stand out from the crowd.

In most cases, an intro paragraph will be relatively short. A good intro will be clear, brief, purposeful, and focused. While there are some exceptions to this rule, it’s common for intro paragraphs to consist of three to five sentences . 

Effectively introducing your essay’s topic, purpose, and getting your reader invested in your essay sounds like a lot to ask from one little paragraph, huh? In the next section, we’ll demystify the intro paragraph format by breaking it down into its core parts . When you learn how to approach each part of an intro, writing one won’t seem so scary!

body-piece-of-cake

Once you figure out the three parts of an intro paragraph, writing one will be a piece of cake!

The 3 Main Parts of an Intro Paragraph

In general, an intro paragraph is going to have three main parts: a hook, context, and a thesis statement . Each of these pieces of the intro plays a key role in acquainting the reader with the topic and purpose of your essay. 

Below, we’ll explain how to start an introduction paragraph by writing an effective hook, providing context, and crafting a thesis statement. When you put these elements together, you’ll have an intro paragraph that does a great job of making a great first impression on your audience!

Intro Paragraph Part 1: The Hook

When it comes to how to start an introduction paragraph, o ne of the most common approaches is to start with something called a hook. 

What does hook mean here, though? Think of it this way: it’s like when you start a new Netflix series: you look up a few hours (and a few episodes) later and you say, “Whoa. I guess I must be hooked on this show!” 

That’s how the hook is supposed to work in an intro paragrap h: it should get your reader interested enough that they don’t want to press the proverbial “pause” button while they’re reading it . In other words, a hook is designed to grab your reader’s attention and keep them reading your essay! 

This means that the hook comes first in the intro paragraph format—it’ll be the opening sentence of your intro. 

It’s important to realize  that there are many different ways to write a good hook. But generally speaking, hooks must include these two things: what your topic is, and the angle you’re taking on that topic in your essay. 

One approach to writing a hook that works is starting with a general, but interesting, statement on your topic. In this type of hook, you’re trying to provide a broad introduction to your topic and your angle on the topic in an engaging way . 

For example, if you’re writing an essay about the role of the government in the American healthcare system, your hook might look something like this: 

There's a growing movement to require that the federal government provide affordable, effective healthcare for all Americans. 

This hook introduces the essay topic in a broad way (government and healthcare) by presenting a general statement on the topic. But the assumption presented in the hook can also be seen as controversial, which gets readers interested in learning more about what the writer—and the essay—has to say.

In other words, the statement above fulfills the goals of a good hook: it’s intriguing and provides a general introduction to the essay topic.

Intro Paragraph Part 2: Context

Once you’ve provided an attention-grabbing hook, you’ll want to give more context about your essay topic. Context refers to additional details that reveal the specific focus of your paper. So, whereas the hook provides a general introduction to your topic, context starts helping readers understand what exactly you’re going to be writing about

You can include anywhere from one to several sentences of context in your intro, depending on your teacher’s expectations, the length of your paper, and complexity of your topic. In these context-providing sentences, you want to begin narrowing the focus of your intro. You can do this by describing a specific issue or question about your topic that you’ll address in your essay. It also helps readers start to understand why the topic you’re writing about matters and why they should read about it. 

So, what counts as context for an intro paragraph? Context can be any important details or descriptions that provide background on existing perspectives, common cultural attitudes, or a specific situation or controversy relating to your essay topic. The context you include should acquaint your reader with the issues, questions, or events that motivated you to write an essay on your topic...and that your reader should know in order to understand your thesis. 

For instance, if you’re writing an essay analyzing the consequences of sexism in Hollywood, the context you include after your hook might make reference to the #metoo and #timesup movements that have generated public support for victims of sexual harassment. 

The key takeaway here is that context establishes why you’re addressing your topic and what makes it important. It also sets you up for success on the final piece of an intro paragraph: the thesis statement.

Elle Woods' statement offers a specific point of view on the topic of murder...which means it could serve as a pretty decent thesis statement!

Intro Paragraph Part 3: The Thesis

The final key part of how to write an intro paragraph is the thesis statement. The thesis statement is the backbone of your introduction: it conveys your argument or point of view on your topic in a clear, concise, and compelling way . The thesis is usually the last sentence of your intro paragraph. 

Whether it’s making a claim, outlining key points, or stating a hypothesis, your thesis statement will tell your reader exactly what idea(s) are going to be addressed in your essay. A good thesis statement will be clear, straightforward, and highlight the overall point you’re trying to make.

Some instructors also ask students to include an essay map as part of their thesis. An essay map is a section that outlines the major topics a paper will address. So for instance, say you’re writing a paper that argues for the importance of public transport in rural communities. Your thesis and essay map might look like this: 

Having public transport in rural communities helps people improve their economic situation by giving them reliable transportation to their job, reducing the amount of money they spend on gas, and providing new and unionized work .

The underlined section is the essay map because it touches on the three big things the writer will talk about later. It literally maps out the rest of the essay!

So let’s review: Your thesis takes the idea you’ve introduced in your hook and context and wraps it up. Think of it like a television episode: the hook sets the scene by presenting a general statement and/or interesting idea that sucks you in. The context advances the plot by describing the topic in more detail and helping readers understand why the topic is important. And finally, the thesis statement provides the climax by telling the reader what you have to say about the topic. 

The thesis statement is the most important part of the intro. Without it, your reader won’t know what the purpose of your essay is! And for a piece of writing to be effective, it needs to have a clear purpose. Your thesis statement conveys that purpose , so it’s important to put careful thought into writing a clear and compelling thesis statement.

How To Write an Introduction Paragraph: Example and Analysis

Now that we’ve provided an intro paragraph outline and have explained the three key parts of an intro paragraph, let’s take a look at an intro paragraph in action.

To show you how an intro paragraph works, we’ve included a sample introduction paragraph below, followed by an analysis of its strengths and weaknesses.

Example of Introduction Paragraph

While college students in the U.S. are struggling with how to pay for college, there is another surprising demographic that’s affected by the pressure to pay for college: families and parents. In the face of tuition price tags that total more than $100,000 (as a low estimate), families must make difficult decisions about how to save for their children’s college education. Charting a feasible path to saving for college is further complicated by the FAFSA’s estimates for an “Expected Family Contribution”—an amount of money that is rarely feasible for most American families. Due to these challenging financial circumstances and cultural pressure to give one’s children the best possible chance of success in adulthood, many families are going into serious debt to pay for their children’s college education. The U.S. government should move toward bearing more of the financial burden of college education. 

Example of Introduction Paragraph: Analysis

Before we dive into analyzing the strengths and weaknesses of this example intro paragraph, let’s establish the essay topic. The sample intro indicates that t he essay topic will focus on one specific issue: who should cover the cost of college education in the U.S., and why. Both the hook and the context help us identify the topic, while the thesis in the last sentence tells us why this topic matters to the writer—they think the U.S. Government needs to help finance college education. This is also the writer’s argument, which they’ll cover in the body of their essay. 

Now that we’ve identified the essay topic presented in the sample intro, let’s dig into some analysis. To pin down its strengths and weaknesses, we’re going to use the following three questions to guide our example of introduction paragraph analysis: 

  • Does this intro provide an attention-grabbing opening sentence that conveys the essay topic? 
  • Does this intro provide relevant, engaging context about the essay topic? 
  • Does this intro provide a thesis statement that establishes the writer’s point of view on the topic and what specific aspects of the issue the essay will address? 

Now, let’s use the questions above to analyze the strengths and weaknesses of this sample intro paragraph. 

Does the Intro Have a Good Hook? 

First, the intro starts out with an attention-grabbing hook . The writer starts by presenting  an assumption (that the U.S. federal government bears most of the financial burden of college education), which makes the topic relatable to a wide audience of readers. Also note that the hook relates to the general topic of the essay, which is the high cost of college education. 

The hook then takes a surprising turn by presenting a counterclaim : that American families, rather than students, feel the true burden of paying for college. Some readers will have a strong emotional reaction to this provocative counterclaim, which will make them want to keep reading! As such, this intro provides an effective opening sentence that conveys the essay topic. 

Does the Intro Give Context?

T he second, third, and fourth sentences of the intro provide contextual details that reveal the specific focus of the writer’s paper . Remember: the context helps readers start to zoom in on what the paper will focus on, and what aspect of the general topic (college costs) will be discussed later on. 

The context in this intro reveals the intent and direction of the paper by explaining why the issue of families financing college is important. In other words, the context helps readers understand why this issue matters , and what aspects of this issue will be addressed in the paper.  

To provide effective context, the writer refers to issues (the exorbitant cost of college and high levels of family debt) that have received a lot of recent scholarly and media attention. These sentences of context also elaborate on the interesting perspective included in the hook: that American families are most affected by college costs.

Does the Intro Have a Thesis? 

Finally, this intro provides a thesis statement that conveys the writer’s point of view on the issue of financing college education. This writer believes that the U.S. government should do more to pay for students’ college educations. 

However, the thesis statement doesn’t give us any details about why the writer has made this claim or why this will help American families . There isn’t an essay map that helps readers understand what points the writer will make in the essay.

To revise this thesis statement so that it establishes the specific aspects of the topic that the essay will address, the writer could add the following to the beginning of the thesis statement:

The U.S. government should take on more of the financial burden of college education because other countries have shown this can improve education rates while reducing levels of familial poverty.

Check out the new section in bold. Not only does it clarify that the writer is talking about the pressure put on families, it touches on the big topics the writer will address in the paper: improving education rates and reduction of poverty. So not only do we have a clearer argumentative statement in this thesis, we also have an essay map!  

So, let’s recap our analysis. This sample intro paragraph does an effective job of providing an engaging hook and relatable, interesting context, but the thesis statement needs some work ! As you write your own intro paragraphs, you might consider using the questions above to evaluate and revise your work. Doing this will help ensure you’ve covered all of your bases and written an intro that your readers will find interesting!

4 Tips for How To Write an Introduction Paragraph

Now that we’ve gone over an example of introduction paragraph analysis, let’s talk about how to write an introduction paragraph of your own. Keep reading for four tips for writing a successful intro paragraph for any essay. 

Tip 1: Analyze Your Essay Prompt

If you’re having trouble with how to start an introduction paragraph, analyze your essay prompt! Most teachers give you some kind of assignment sheet, formal instructions, or prompt to set the expectations for an essay they’ve assigned, right? Those instructions can help guide you as you write your intro paragraph!

Because they’ll be reading and responding to your essay, you want to make sure you meet your teacher’s expectations for an intro paragraph . For instance, if they’ve provided specific instructions about how long the intro should be or where the thesis statement should be located, be sure to follow them!

The type of paper you’re writing can give you clues as to how to approach your intro as well. If you’re writing a research paper, your professor might expect you to provide a research question or state a hypothesis in your intro. If you’re writing an argumentative essay, you’ll need to make sure your intro overviews the context surrounding your argument and your thesis statement includes a clear, defensible claim. 

Using the parameters set out by your instructor and assignment sheet can put some easy-to-follow boundaries in place for things like your intro’s length, structure, and content. Following these guidelines can free you up to focus on other aspects of your intro... like coming up with an exciting hook and conveying your point of view on your topic!

Tip 2: Narrow Your Topic

You can’t write an intro paragraph without first identifying your topic. To make your intro as effective as possible, you need to define the parameters of your topic clearly—and you need to be specific. 

For example, let’s say you want to write about college football. “NCAA football” is too broad of a topic for a paper. There is a lot to talk about in terms of college football! It would be tough to write an intro paragraph that’s focused, purposeful, and engaging on this topic. In fact, if you did try to address this whole topic, you’d probably end up writing a book!

Instead, you should narrow broad topics to  identify a specific question, claim, or issue pertaining to some aspect of NCAA football for your intro to be effective. So, for instance, you could frame your topic as, “How can college professors better support NCAA football players in academics?” This focused topic pertaining to NCAA football would give you a more manageable angle to discuss in your paper.

So before you think about writing your intro, ask yourself: Is my essay topic specific, focused, and logical? Does it convey an issue or question that I can explore over the course of several pages? Once you’ve established a good topic, you’ll have the foundation you need to write an effective intro paragraph . 

body-stack-of-textbooks-red

Once you've figured out your topic, it's time to hit the books!

Tip 3: Do Your Research

This tip is tightly intertwined with the one above, and it’s crucial to writing a good intro: do your research! And, guess what? This tip applies to all papers—even ones that aren’t technically research papers. 

Here’s why you need to do some research: getting the lay of the land on what others have said about your topic—whether that’s scholars and researchers or the mass media— will help you narrow your topic, write an engaging hook, and provide relatable context. 

You don't want to sit down to write your intro without a solid understanding of the different perspectives on your topic. Whether those are the perspectives of experts or the general public, these points of view will help you write your intro in a way that is intriguing and compelling for your audience of readers. 

Tip 4: Write Multiple Drafts

Some say to write your intro first; others say write it last. The truth is, there isn’t a right or wrong time to write your intro—but you do need to have enough time to write multiple drafts . 

Oftentimes, your professor will ask you to write multiple drafts of your paper, which gives you a built-in way to make sure you revise your intro. Another approach you could take is to write out a rough draft of your intro before you begin writing your essay, then revise it multiple times as you draft out your paper. 

Here’s why this approach can work: as you write your paper, you’ll probably come up with new insights on your topic that you didn’t have right from the start. You can use these “light bulb” moments to reevaluate your intro and make revisions that keep it in line with your developing essay draft. 

Once you’ve written your entire essay, consider going back and revising your intro again . You can ask yourself these questions as you evaluate your intro: 

  • Is my hook still relevant to the way I’ve approached the topic in my essay?
  • Do I provide enough appropriate context to introduce my essay? 
  • Now that my essay is written, does my thesis statement still accurately reflect the point of view that I present in my essay?

Using these questions as a guide and putting your intro through multiple revisions will help ensure that you’ve written the best intro for the final draft of your essay. Also, revising your writing is always a good thing to do—and this applies to your intro, too!

How to Write an Introduction for a Research Paper

An introductory paragraph is vital for any academic paper. It allows you to show reviewers why your research topic is worth reading about. In this article, we will explore the tips to make a good introduction paragraph. You’ll get a step-by-step tutorial on writing your paper’s informative yet laconic intro.

What is the purpose of an introduction?

The purpose of a research paper intro is to provide an overview and context for the study being conducted. A research paper engages the reader, establishes the importance of the research topic, and outlines the study’s objectives and scope.

The paper intro also presents the question or hypothesis and summarizes relevant background characteristics and existing literature.

An effective introduction helps the reader understand the significance and relevance of the research paper and sets the stage for the subsequent sections. The introduction captures the reader’s attention and creates a foundation for understanding the research and its contributions.

The key elements of a scientific paper introduction

The introduction of your research paper should include several key elements, including the problem statement, hypothesis/thesis/research question, purpose, and background.

Let’s explore each of these parts of the research paper intro in detail:

  • Problem Statement : identifies the specific issue or gap in knowledge that the research paper aims to address. It highlights the problem’s relevance, significance, and potential impact on the field of study. The problem statement sets the stage for the research by clearly stating the project or research gap.
  • Hypothesis / Thesis / Research Question : a paper hypothesis predicts the relationship between variables, a thesis statement presents the main argument or claim, and a research question seeks to put a specific aspect on a research paper.
  • Purpose: describes the overall objective or goal the research paper aims to achieve. It outlines the researcher’s intention and provides a clear direction for the investigation. The purpose statement typically explains why the research is being conducted and what the researcher hopes to accomplish by the end of the study.
  • Background : provides the necessary context and information to familiarize readers with the research paper. It presents a concise review of the relevant literature, previous studies, and theoretical frameworks that have shaped the understanding of the problem.

Shortly, the introduction section of a research paper combines these key elements to introduce the problem, state the hypothesis/thesis/research question, define the paper’s purpose, and provide the background necessary for readers to understand the significance and context of the study.

How to write an effective intro?

To start an introduction for a research paper, consider the following steps:

  • Hook the reader : begin with a compelling opening sentence or a thought-provoking statement that grabs the reader’s attention. This could be an interesting fact, a relevant anecdote, or a surprising statistic related to your research paper.
  • Provide background information : offer a brief overview of the paper and its significance in the field. This helps to improve the structure of an introduction and demonstrate why it is important to investigate the point further in a paper.
  • State the problem : clearly articulate the problem statement or research gap your study aims to address. Explain the specific issue or gap in knowledge that your research paper seeks to explore, emphasizing its relevance and potential impact.
  • Present the research question/hypothesis/thesis : formulate a concise and focused research question, hypothesis, or thesis statement in the intro that guides your scientific paper. This sets the direction for your research and provides a clear focus for the reader.
  • Outline the purpose and objectives : explain the overall purpose of your research paper and the specific objectives you aim to achieve. This helps readers understand why your study is being conducted and what you hope to accomplish.
  • Preview the structure : briefly introduce the organization and structure of your research paper. Mention the main sections or components that will be covered, giving readers a sense of what to expect as they continue reading the paper.

Remember, the intro should be concise and engaging, providing a clear roadmap for your research and capturing the reader’s interest from the very beginning. There are different ways to start a research paper, and you can pick the intro that suits you best.

Writing an introduction to a research paper: key steps

Here’s a short guide on getting you started with an introduction:

  • Start with an attention-grabbing opening : begin your intro with a captivating statement, a relevant quote, a surprising fact, or an intriguing anecdote. This will engage the reader’s interest and make them curious about your research paper.
  • Provide background information : write a brief overview of the research topic to provide context and establish the importance of the subject matter. Discuss key concepts, definitions, or historical background relevant to your study. This section should help the reader understand the broader context of your research paper.
  • State the research problem or gap : clearly define the specific problem or research gap your study aims to address. Explain why this problem is significant and deserving of investigation. This helps the reader understand the purpose and relevance of your research paper.
  • Present your research question or thesis statement : formulate a clear and concise research question, hypothesis, or thesis statement that serves as the central focus of your study. This statement should guide your research paper and articulate your introduction format.
  • Outline the structure of the paper : write a brief preview of your research paper’s main sections and organization. This helps the reader understand the flow of your paper and what to expect in each section. Provide a roadmap by mentioning the key points or arguments discussed in subsequent sections.

By following these steps, you can create an introduction that grabs the reader’s attention and sets the stage for the rest of your research paper, clearly understanding your study’s problem, purpose, and structure.

Writing a checklist for a proper college paper introduction

Here’s a short writing checklist for a research paper intro:

  • Attention-grabbing opening:
  • Does the research paper introduction example start with a compelling statement, relevant quote, surprising fact, or intriguing anecdote?
  • Is the opening engaging enough to capture readers’ attention and make them curious about the research paper?
  • Background information:
  • Have you provided a concise overview of the research topic, including relevant definitions, concepts, or historical context?
  • Does the background information help the reader understand the broader context and importance of the subject matter?
  • Clear problem statement:
  • Have you clearly stated the specific problem or research gap that your study aims to address?
  • Does a research introduction have a well-defined, strong, and significant problem statement?
  • Research question or thesis statement:
  • Have you presented a clear and concise research question, hypothesis, or thesis statement that guides your paper?
  • Does the research question or thesis statement align with the problem statement and set the direction for your research paper?
  • Structure and organization:
  • Did you write a brief overview of the structure and organization of the research paper?
  • Does the introduction outline the main sections or components covered in the paper?
  • Coherence and flow:
  • Is the intro logically organized? Does it have smooth transitions between ideas and paragraphs?
  • Does the intro flow smoothly from the opening to the problem statement, research question, and purpose?
  • Conciseness and clarity:
  • Have you kept the introduction concise, avoiding unnecessary details or tangents?
  • Is the language clear, avoiding jargon or overly technical terms that may confuse the reader?
  • Relevance and significance:
  • Have you clearly explained the relevance and significance of the research topic and the paper’s potential impact?
  • Does the introduction effectively communicate why your research is important and worth exploring?

This checklist will help you to review your research essay introduction to ensure it effectively grabs the reader’s attention, provides necessary background information, states the problem clearly, presents a focused research question or thesis statement, outlines the structure of the paper, and maintains coherence and clarity throughout.

Types of intro formats

Different academic disciplines may follow specific formatting styles for research introduction, such as MLA (Modern Language Association), APA (American Psychological Association), Chicago, ASA (American Sociological Association), and AMA (American Medical Association).

service-1

To write an introduction paragraph, you should understand the differences between the most common academic formats for your future paper.

MLA (Modern Language Association):

  • Primarily used in humanities, literature, and arts disciplines.
  • Features in-text citations using the author-page format (e.g., “Smith 45”).

APA (American Psychological Association):

  • Commonly used in social sciences, psychology, and education.
  • Utilizes in-text citations with the author-date format (e.g., “Smith, 2019”).
  • Often used in history, humanities, and some social sciences.
  • Offers two styles: the notes-bibliography system and the author-date system.
  • Includes a bibliography page to list all sources used.

ASA (American Sociological Association):

  • Primarily used in sociology and related social sciences.
  • Utilizes in-text citations with the author-date format (e.g., “Smith 2019”).

AMA (American Medical Association):

  • Commonly used in medical, health, and biological sciences.
  • Features in-text citations with a superscript number (e.g., “Smith^1”).
  • Emphasizes accuracy and consistency in citation style.

All formatting styles mean a set of rules and guidelines for citing sources, formatting headings, page layout, and referencing. It’s important to consult the specific style guide or manual associated with your field of study before you write.

These might include guidelines provided by your institution to ensure proper paper formatting and adherence of a research introduction to the chosen style.

Research introduction sample

Now that you know how the idea goes in the introduction of a research paper, let’s see the practical examples of good and bad introductions and discuss their differences.

Good example:

Title: “Exploring the Impact of Climate Change on Biodiversity: A Comprehensive Analysis”

Introduction:

Climate change is a pressing global issue that has far-reaching consequences for our planet. Its effects on various ecosystems, particularly biodiversity loss, have attracted significant attention from researchers and policymakers alike.

This research paper aims to provide a comprehensive analysis of the impact of climate change on biodiversity, focusing on key regions and species vulnerable to these changes. By examining the latest scientific literature, empirical studies, and expert opinions, we will explore the complex interplay between climate change and biodiversity loss, shed light on the underlying mechanisms, and propose potential mitigation strategies.

Understanding these dynamics is crucial for developing effective conservation strategies and promoting sustainable practices that will help preserve our planet’s invaluable natural heritage.

Bad example:

Title: “Climate Change and Biodiversity”

Climate change and biodiversity are two important topics that have received considerable attention recently. Climate change refers to the long-term alteration of temperature and precipitation patterns, while biodiversity encompasses the variety of life forms found on Earth.

In this research paper, we will discuss the impact of climate change on biodiversity and explore various examples and case studies. The paper will also highlight the significance of addressing this issue and present potential solutions.

By delving into this subject, we aim to contribute to the existing body of knowledge and raise awareness about the importance of protecting biodiversity in climate change.

To begin an introduction paragraph, don’t provide too much background or theory at once. Remember to arrange your thoughts concisely while keeping the important information for the paper body.

A good intro should answer the four basic questions:

  • What was I studying?
  • Why was this topic important to investigate?
  • What did we know about this topic before I did this study?
  • How will this study advance our knowledge?

Remember that you might not get a second chance to create a positive first impression. That’s why it’s equally important to keep your paper laconic and to end an introduction paragraph with a call to action to read your research paper.
