The Dreaded Introductory Paragraph

Writing the introductory paragraph can be a frustrating and slow process -- but it doesn't have to be.  If you planned your paper out, then most of the introductory paragraph is already written.  Now you just need a beginning and an end.

Here's an introductory paragraph for a paper I wrote.  I started the paper with a factoid, then presented each main point of my paper and then ended with my thesis statement.

Writing a Research Paper Introduction | Step-by-Step Guide

Published on September 24, 2022 by Jack Caulfield . Revised on March 27, 2023.

Writing a Research Paper Introduction

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

  • Present your topic and get the reader interested
  • Provide background or summarize existing research
  • Position your own approach
  • Detail your specific research problem and problem statement
  • Give an overview of the paper’s structure

The introduction looks slightly different depending on whether your paper presents the results of original empirical research or constructs an argument by engaging with a variety of sources.

Table of contents

Step 1: introduce your topic, step 2: describe the background, step 3: establish your research problem, step 4: specify your objective(s), step 5: map out your paper, research paper introduction examples, frequently asked questions about the research paper introduction.

The first job of the introduction is to tell the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening hook.

The hook is a striking opening sentence that clearly conveys the relevance of your topic. Think of an interesting fact or statistic, a strong statement, a question, or a brief anecdote that will get the reader wondering about your topic.

For example, the following could be an effective hook for an argumentative paper about the environmental impact of cattle farming:

A more empirical paper investigating the relationship of Instagram use with body image issues in adolescent girls might use the following hook:

Don’t feel that your hook necessarily has to be deeply impressive or creative. Clarity and relevance are still more important than catchiness. The key thing is to guide the reader into your topic and situate your ideas.

This part of the introduction differs depending on what approach your paper is taking.

In a more argumentative paper, you’ll explore some general background here. In a more empirical paper, this is the place to review previous research and establish how yours fits in.

Argumentative paper: Background information

After you’ve caught your reader’s attention, specify a bit more, providing context and narrowing down your topic.

Provide only the most relevant background information. The introduction isn’t the place to get too in-depth; if more background is essential to your paper, it can appear in the body .

Empirical paper: Describing previous research

For a paper describing original research, you’ll instead provide an overview of the most relevant research that has already been conducted. This is a sort of miniature literature review —a sketch of the current state of research into your topic, boiled down to a few sentences.

This should be informed by genuine engagement with the literature. Your search can be less extensive than in a full literature review, but a clear sense of the relevant research is crucial to inform your own work.

Begin by establishing the kinds of research that have been done, and end with limitations or gaps in the research that you intend to respond to.

The next step is to clarify how your own research fits in and what problem it addresses.

Argumentative paper: Emphasize importance

In an argumentative research paper, you can simply state the problem you intend to discuss, and what is original or important about your argument.

Empirical paper: Relate to the literature

In an empirical research paper, try to lead into the problem on the basis of your discussion of the literature. Think in terms of these questions:

  • What research gap is your work intended to fill?
  • What limitations in previous work does it address?
  • What contribution to knowledge does it make?

You can make the connection between your problem and the existing research using phrases like the following.

Now you’ll get into the specifics of what you intend to find out or express in your research paper.

The way you frame your research objectives varies. An argumentative paper presents a thesis statement, while an empirical paper generally poses a research question (sometimes with a hypothesis as to the answer).

Argumentative paper: Thesis statement

The thesis statement expresses the position that the rest of the paper will present evidence and arguments for. It can be presented in one or two sentences, and should state your position clearly and directly, without providing specific arguments for it at this point.

Empirical paper: Research question and hypothesis

The research question is the question you want to answer in an empirical research paper.

Present your research question clearly and directly, with a minimum of discussion at this point. The rest of the paper will be taken up with discussing and investigating this question; here you just need to express it.

A research question can be framed either directly or indirectly.

  • This study set out to answer the following question: What effects does daily use of Instagram have on the prevalence of body image issues among adolescent girls?
  • We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls.

If your research involved testing hypotheses , these should be stated along with your research question. They are usually presented in the past tense, since the hypothesis will already have been tested by the time you are writing up your paper.

For example, the following hypothesis might respond to the research question above:

  • Academic style
  • Vague sentences
  • Style consistency

introduction paragraph example for research paper

The final part of the introduction is often dedicated to a brief overview of the rest of the paper.

In a paper structured using the standard scientific “introduction, methods, results, discussion” format, this isn’t always necessary. But if your paper is structured in a less predictable way, it’s important to describe the shape of it for the reader.

If included, the overview should be concise, direct, and written in the present tense.

  • This paper will first discuss several examples of survey-based research into adolescent social media use, then will go on to …
  • This paper first discusses several examples of survey-based research into adolescent social media use, then goes on to …

Full examples of research paper introductions are shown in the tabs below: one for an argumentative paper, the other for an empirical paper.

  • Empirical paper

Are cows responsible for climate change? A recent study (RIVM, 2019) shows that cattle farmers account for two thirds of agricultural nitrogen emissions in the Netherlands. These emissions result from nitrogen in manure, which can degrade into ammonia and enter the atmosphere. The study’s calculations show that agriculture is the main source of nitrogen pollution, accounting for 46% of the country’s total emissions. By comparison, road traffic and households are responsible for 6.1% each, the industrial sector for 1%. While efforts are being made to mitigate these emissions, policymakers are reluctant to reckon with the scale of the problem. The approach presented here is a radical one, but commensurate with the issue. This paper argues that the Dutch government must stimulate and subsidize livestock farmers, especially cattle farmers, to transition to sustainable vegetable farming. It first establishes the inadequacy of current mitigation measures, then discusses the various advantages of the results proposed, and finally addresses potential objections to the plan on economic grounds.

The rise of social media has been accompanied by a sharp increase in the prevalence of body image issues among women and girls. This correlation has received significant academic attention: Various empirical studies have been conducted into Facebook usage among adolescent girls (Tiggermann & Slater, 2013; Meier & Gray, 2014). These studies have consistently found that the visual and interactive aspects of the platform have the greatest influence on body image issues. Despite this, highly visual social media (HVSM) such as Instagram have yet to be robustly researched. This paper sets out to address this research gap. We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls. It was hypothesized that daily Instagram use would be associated with an increase in body image concerns and a decrease in self-esteem ratings.

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 .

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

Introduction Paragraph Examples and Writing Tips

Abstract | Introduction | Literature Review | Research question | Materials & Methods | Results | Discussion | Conclusion

In this blog, we look at how to write the introduction paragraph of a research paper. We will go through a few introduction paragraph examples and understand how to construct a great introduction paragraph for your research paper.

1. What is the purpose of the introduction paragraph?

Introduction example

The opening paragraph is the first paragraph of your research paper. The opening paragraph is where you want to attract your readers and draw them into your paper. This typically occupies one or two paragraphs. The introduction section must provide necessary background knowledge, so that the readers can understand the motivation behind your experiments and appreciate your findings. After reading your introductory paragraph, the reader should  be familiar with the main idea of your paper and understand why your topic is important.

2. What are the 5 parts of an introduction paragraph?

The introduction paragraph of a research paper should typically contain the following components.

Hook You can start with a hook . A hook is nothing but an attractive opening statement.

A broad introduction to the field Here, you can define the general topic of your research.

The specific topic of study Then, the next step is to narrow down your topic and reveal the specific focus of your paper.

Problem definition Then you have to define your problem. You must explain clearly what problem your paper is trying to address or solve.

Importance of your work Then you need to establish why the topic is timely or important?

Benefits of conducting research Here, you can explain the benefits your work and how it will advance the current understanding of the topic.

3.1. What is a Hook?

Hook in introduction

The opening paragraph typically should start with a sentence that piques the interest of your readers. This is called a hook.  The idea is to hook your reader and reel them in. Just like using hooks with bait to capture a fish in a pond. These are statements designed to grab the reader’s attention and make them want to read more of your paper.

3.2. How to Write a Hook?

One thing to bear in your mind is that most people reading your paper will have some background knowledge about the topic. So you have to find a way to say things that people already know in a slightly different and interesting manner. The trick is to use statistics, facts,  quotations, and questions to make things interesting to the readers. These are called hooks.

Hooks ideas for introduction passage

3.3. Hook Examples

Now, let’s look at some examples of hooks.

3.3.1. Hook Example #1

Here is an opening statement. Here we are trying to establish that breast cancer is a pretty bad disease. This statement is not very punchy. It is pretty bland and doesn’t convey the seriousness of the situation.

Breast cancer is the most common cancer in women in the United States.

Now, Let’s use some statistics and rewrite the statement. Look at this statement now, the readers will instantly understand how deadly breast cancer is, because you are using numbers to put things into perspective. This will get the reader’s attention straight away, and they will be keen to read more of your paper to find out if you are proposing something to fix this terrible situation.

In 2020, 43,700 females died from breast cancer in the US. It is the most common cancer in women accounting for 30% (or 1 in 3) of all new female cancers.

3.3.2. Hook Example #2

Here is another example. Here is an opening statement about global warming. There is nothing new here. Most people know that global warming is bad.

Global warming is causing damage to the environment due to increase in Co2 emissions.

Now, let’s frame this as a question with some facts and numbers. How about this? This sounds way much better because it conveys the urgency of the situation. 

Did you know that the Last Decade Was the Hottest in 125,000 Years and there is more Co2 in our atmosphere than at any time in human history?

4. Introduction Paragraph Examples

Let’s look at some examples of introduction paragraphs. The examples we have chosen are quite short, so that it is easy for you to understand. We have chosen examples from different fields and of different formats. 

4.1 Example #1 (Social sciences paper)

Here is an introduction paragraph example from a social sciences research paper, and it is about AI, which stands for artificial intelligence. We are providing a broad overview of the topic in the first couple of lines. We are talking about the popularity of the AI, and the recent advancements that has happened in the field.

Artificial intelligence (AI) has received considerable attention in recent years due to its application in various fields such as manufacturing, healthcare, security, etc. In recent years, methods have been proposed to produce sufficiently intelligent software capable of reprogramming. Such production presents a number of challenges as AI may threaten human employment in the future. The development of new programmes will facilitate a better understanding of just how far AI can go. _ Broad overview _ Narrowdown topic _ Problem definition _ Importance of topic

Then, we move on to the problem definition. The problem is about AI threatening the human employment in the future by taking up all the jobs. Then, in the next statement we are talking about the importance of exploring the issue, so that we can understand how far AI will impact our lives in the future.

You can see that this passage ticks all the boxes, there is relevant background information, a clear definition of the problem, and information about the importance of conducting research on this topic.

4.2 Example #2 (Business & Marketing paper)

This introduction passage example is from a marketing and business paper. In this example, we are using a lot of numbers to establish why it is important and timely to conduct research in this domain. We are telling the readers that there are millions of Asians living in UK and their numbers are increasing every year. They have this huge spending power and not many researchers have looked into how and where they spend their money. So, the time has come to explore this market.  A lot of interesting data and facts are provided to the readers. And, that is the reason why this is such a good introduction.

Approximately 60.5 million Asians lived in the United Kingdom in 2022, and this will grow at a rate of approximately 13.19% over the next five years[1]. The purchasing power of this demographic is expected to reach over $2.26 trillion by 2025[2]. This market is a growing and relatively unexplored segment in the marketing literature. Researchers and practitioners should therefore be interested in the increasing importance of this market and the potential it holds for businesses. _ Hook _ Problem definition _ Importance/timeliness of topic

4.3 Example #3 (Medicine paper)

Here is an introduction paragraph example from a medicine paper. We are starting the passage with a hook by providing an interesting statistic about obesity. After starting with a broad statement, we are narrowing down the topic. We are dropping a hint that our paper is to do with vitamin d and obesity. With the next statement, we are establishing the importance of the topic. We are saying that a lot of people are dying due to obesity, and vitamin D is causing a lot of health issues, so we must do something about it.

Obesity is a worldwide disease. In 2020, more than 2 billion adults, 18 years and older, were overweight. There is a general consensus in the research community that there is a strong association between obesity and Vitamin D. This represents an important and timely topic because obesity is currently fifth greater risk of mortality, and Vitamin D deficiency has been associated with variety of diseases. Better understanding of this link will greatly aid medicalpractitioners in effective treatment of obese patients. _ Hook _ Problem definition _ Importance/timeliness of topic _ Benefits of conducting research

Then, in the final statement of the intro paragraph, we explain how conducting research in this field will benefit the community. In our case, doctors will be able to prescribe better treatment options for obese patients. This is a well written introduction paragraph that nicely introduces the main idea of your paper and tells the readers why your topic is important.

4.4 Example #4 (Engineering paper)

Here is another introduction paragraph example from an engineering paper.  Here, we are starting  the passage with the problem definition itself. We are saying that it is challenging to perform measurements on a complex system, because there are so many different things you have to consider. Then, we emphasis the popularity of the topic by saying that there is an active research community investigating  this issue at the moment. Then, we finish off the passage by explaining the benefits we will enjoy if we manage to solve this problem. And, we have listed all the applications that will benefit from this research.

Obtaining an accurate measurement of a complex system is a challenging task, as it can make it difficult to account for all of the variables that may affect the measurement. Research in this area is of great interest and with a very active research community. Obtaining an accurate measurement is useful for a number of applications, including modelling and forecasting, quality control, and data analysis. _ Problem definition _ Importance/popularity of the topic _ Benefits of conducting research

5. Frequently Asked Questions

The opening paragraph of the introduction should be one or two paragraphs long. The entire introduction section comprising the opening paragraph, literature review, and research questions should be around 10% to 15% of the total length of the research paper.

Please do not cram your introduction with large amounts of text. Don’t treat your readers as if they don’t know anything. Most people who are reading your paper will have some knowledge about the field. Be selective and decide what is important for your readers.

If you have a super long introduction, then it means that you don’t have a lot to say about the actual research you have done. Most reviewers won’t like this, and your paper is likely to be rejected. So, keep it short and sweet.

(1) Make sure you use scientific jargon that is relevant to your field in your text. Scientific jargon are technical terms specific to your discipline. Using scientific jargon has two advantages, number one, you are using the language used by your peers in your field, and number two, it makes your text significantly shorter.

(2) Don’t delve on the broad topic for too long in your introduction. Try to narrow down to the specific topic as soon as possible. The readers are less interested in the general area of research. They want to quickly learn what is the specific topic of your research.

(3) Introduction paragraph is the best place to introduce notations and technical definitions. This can include symbols, characters, terminologies, abbreviations, acronyms etc. Notations and definitions can help you to express very large names and numbers in a form that is easy to understand to your readers.

A research paper introduction holds perhaps the most importance for a study to be successful. After a good research paper abstract , it is the introduction that builds the interest in a reader to continue reading the research paper. If the introduction turns out to be dull and drab, then the study would be a failed one.

A good research paper needs a lot of background study, which you often fail to do. To make your work easier, Management Paper is there for you to help you write yours efficiently.

Key Features of a Research Paper Introduction

  • It forms the basic part of both the research paper as well as the research proposal .
  • Apart from giving a general notion about the research paper topic , it includes important elements such as background, aim, objectives, questions and many more.
  • It must contain the questions ‘WHY’: why is the research conducted, why it is important, why this chosen topic and so on is.
  • It helps in pointing out the knowledge gaps and fills them up throughout the paper.
  • Use precise and clear points.

The Most Commonly Included Elements in The Research Papers

There are different kinds of research papers like essays, reports, dissertations and journals. The introduction which is generally used in case of all other types of research paper except dissertations are similar in nature. Such an introduction is similar to a summary of the topic, defining the problem, stating the aims and objectives that are going to be established through the research.

But in case of dissertation, in a good research paper format the introduction is presented in great detail by dividing the section into the following parts:

  • Research background
  • Research problem
  • Research rationale
  • Research aim
  • Research objectives
  • Research hypothesis
  • Research questions

Apart from this, many papers include time plan, scope and limitations of the research too. The experts from the team of Management Paper can help you with your paper writing and also make you understand the various aspects of a research paper.

Some Significant Examples of Research Paper Introduction

Research paper introduction example #1, topic: impact of leadership effectiveness on employees for the company amazon (dissertation).

The history and the various past events related to the topic are being mentioned in this section. Thsi supplies context to the paper and contains both relevant and important studies. Authenticating your information is a must by in-text citations.

The research problem states a specific area of concern, a bothering question, a difficulty which is to be eliminated or a condition that demands improvement. The missing knowledge about the topic is being found out through this and then only you can do further research about the problem.

The rationale answers the question of why the research is being conducted and thus states its importance.

The things that are expected to be achieved at the end of the research are generally mentioned here.

The objectives are the various goals or targets that are to be established and achieved throughout the study.

The research question points out the facts that are to be established through the paper and provides the research with a clear focus and purpose.

This is a specific predictive statement about the possible future outcome of the study which is mostly based upon the relationship between different variables or on a single variable.

Research Paper Introduction Example # 2

Topic: implementing online customer support service through chat portal at aldi, research paper introduction example # 3, topic: compare and contrast the policies for the aged people in various countries.

In both the second and the third example, the introduction is written in a single paragraph. In the first line itself you must introduce the topic. Try to avoid embellishments. Write any remarkable event about the topic then. Explain the problem and the purpose of the research. Try to build a reasonable thesis statement. Then with few lines, insert a smooth transition to make a shift from the introduction to the body.

What is a Research Paper Introduction?

A research paper introduction is the opening section of a research paper that provides an overview of the research. It reflects more than just introducing the topic of the study. The introduction gives a comprehensive yet concise overview of the research topic and tries to establish its significance in front of the readers.

In a research paper introduction, the writer provides background information on the topic, states the research problem or question, and presents the thesis statement or main argument that will be supported in the rest of the paper. Writers may also provide a brief overview of the research methodology that will be used in the research, as well as any limitations or scope that should be considered. Overall, the goal of a research paper introduction is to provide the readers with enough information to understand the context of the research and why it is important, while also setting up the rest of the paper for success.

What are the Key Features of a Research Paper Introduction?

A research paper introduction is a fundamental part of both the research paper and the proposal. It goes beyond providing a brief overview of the research paper topics , as it includes crucial elements such as background, aims, objectives, and research questions.

  • The introduction must answer the ‘why’ questions related to the research, such as why the study is being conducted, why it is important, and why this particular topic was chosen.
  • Additionally, the introduction helps to identify knowledge gaps and addresses them throughout the paper.
  • To ensure effectiveness, it is important to use concise and clear language when presenting the introduction.

What to Include in the Research Paper Introduction?

According to a structured research paper outline , there are several key components that you should include in the research paper introduction to effectively set the stage for your research and engage your audience. Here are the fundamental elements to include in the introduction:

  • Introduction to the Topic/ Hook

The hook is the opening sentence or phrase of your introduction that grabs the reader’s attention and draws them in. It should be interesting, relevant, and perhaps even surprising. A good hook could be a provocative question, a startling statistic, a relevant quote, or an anecdote that sets the stage for your research.

  • Research Background

The research background provides context for your study by explaining the background of the subject you are researching. This could include explaining why the topic is important, what has been done on the topic in the past, and any relevant background information that the reader needs to know. The purpose of the background section is to provide context and establish the relevance of the research.

  • Problem Statement

The problem statement is a specific, focused, and concise statement that outlines the research problem or questions that your study aims to address. The problem statement should make it clear what you are researching and exemplify its importance.

The research rationale explains the justification for your study and why it is important to address the research problem. This component should explain the significance and relevance of your research in the context of the larger field or industry.

The research aim is a general statement that describes the overall goal of your study. It should be broad enough to encompass the scope of your research but specific enough to provide direction for your research objectives.

  • Research Objectives

The research objectives are specific, measurable, and achievable goals that you aim to accomplish through your research. They should be closely linked to your research problem and aim and should provide a clear roadmap for your research.

A research hypothesis is a statement that predicts the relationship between two or more variables in your study. It should be testable and provide a clear direction for your research. Not all research papers will have a hypothesis, but they are common in quantitative research.

  • Research Questions

Research questions are specific, focused questions that you aim to answer through your research. They should be closely linked to your research problem and aim and should guide your research methodology and analysis.

  • Thesis Statement

The thesis statement is the central argument or research question of your paper. It should be clear and concise and should summarize the main argument or research question that you will support with evidence and analysis in the body of your paper.

  • Methodology

You may briefly outline the methodology and approach that you will use in your research. You can also provide the research limitations or scope. The methodology section should provide an idea of how you will conduct your research and what you hope to accomplish.

  • Significance

Finally, you must explain the significance of your research and what it can contribute to the field. This could include implications for practice, policy, or future research. The significance section should make it clear why your research is important and what impact it could have on the field.

Overall, these components work together to provide a clear and compelling introduction to your research paper, outlining the context, purpose, and direction of your study.

Research Paper Introduction Example – A Detailed Illustration

Below we have curated a detailed research paper introduction example that covers all the components discussed above for aiding you with better comprehension.

Topic: The impact of minimum wage laws on small businesses


The minimum wage is a highly debated topic in politics and economics. While minimum wage laws aim to improve the standard of living for workers, they also have potential consequences for small businesses, which often have limited resources. The purpose of this research paper is to examine the impact of minimum wage laws on small businesses.

Research Background:

Minimum wage laws have been a topic of debate for decades, with proponents arguing that they improve the standard of living for workers and opponents claiming that they lead to job loss and increased prices. In recent years, several states and cities in the United States have increased their minimum wage rates, which has raised concerns about the impact on small businesses.

Research Problem:

The research problem for this study is to determine how minimum wage laws impact small businesses. Specifically, we aim to answer the question: What are the potential consequences of minimum wage laws for small businesses?

Research Rationale:

Understanding the impact of minimum wage laws on small businesses is important for several reasons. Small businesses are often the engine of economic growth, and any negative consequences of minimum wage laws could have far-reaching implications for local and national economies. Additionally, the political debate around minimum wage laws is often focused on the impact on workers, with less attention paid to the potential consequences for small businesses.

Research Aim:

This study aims to determine the impact of minimum wage laws on small businesses. Specifically, we aim to identify the potential consequences of minimum wage laws for small businesses and explore strategies that small businesses can use to mitigate these consequences.

Research Objectives:

The objectives of this study are as follows:

  • To review the existing literature on the impact of minimum wage laws on small businesses.
  • To analyze the potential consequences of minimum wage laws for small businesses, including changes in employment, pricing, and profitability.
  • To identify strategies that small businesses can use to mitigate the potential negative consequences of minimum wage laws.

Research Hypothesis:

We hypothesize that minimum wage laws have a negative impact on small businesses, leading to job loss, increased prices, and reduced profitability. However, we also believe that small businesses can take steps to mitigate these negative consequences, such as increasing productivity and finding new revenue streams.

Research Questions:

  • What is the existing literature on the impact of minimum wage laws on small businesses?
  • How do minimum wage laws impact small businesses in terms of employment, pricing, and profitability?
  • What strategies can small businesses use to mitigate the potential negative consequences of minimum wage laws?

Thesis Statement: “While minimum wage laws aim to improve the lives of low-wage workers, they often have unintended consequences for small businesses, including increased operating costs and reduced employment opportunities.”

Significance: The minimum wage laws are a widely debated policy issue with potential impacts on both workers and businesses. Understanding the effects of these laws on small businesses is crucial for policymakers and business owners alike, as it can inform decisions regarding minimum wage legislation and business practices.

Research Paper Introduction Examples

Below we have provided two elucidative research paper introduction examples to help understand how an introduction is typically written.

Title: Exploring the Effectiveness of Mindfulness-Based Interventions for Sustainable Weight Loss and Improved Health Outcomes in Individuals with Obesity

Obesity is a major public health concern, with nearly 40% of American adults classified as obese. In recent years, the prevalence of obesity has increased dramatically, leading to a rise in related health problems such as type 2 diabetes, cardiovascular disease, and certain types of cancer. While many factors contribute to the development of obesity, including genetics and environmental factors, dietary habits and physical activity levels are two of the most important modifiable risk factors. However, traditional weight loss interventions such as diet and exercise programs have had limited success in producing sustained weight loss. As a result, there is a need for innovative approaches to weight management that address the underlying behavioral and psychological factors that contribute to obesity. This paper aims to explore the effectiveness of mindfulness-based interventions in promoting sustainable weight loss and improving overall health outcomes in individuals with obesity. Through a comprehensive review of the existing literature and a randomized controlled trial, this study aims to contribute to the development of more effective weight management strategies that can have a significant impact on public health.

Breakdown: In this example, the hook is the statistic on the prevalence of obesity and its related health problems. The background provides context on the contributing factors to obesity and the limitations of traditional weight loss interventions. The research problem is the need for innovative approaches to weight management that address behavioral and psychological factors. The research rationale is the potential impact of these approaches on public health. The research aim is to explore the effectiveness of mindfulness-based interventions. The research objectives are to conduct a literature review and a randomized controlled trial. The research hypothesis is that mindfulness-based interventions will lead to sustained weight loss and improved health outcomes. The research questions are what is the effectiveness of mindfulness-based interventions in promoting weight loss and improving health outcomes in individuals with obesity? Lastly, the thesis statement is that this study aims to contribute to the development of more effective weight management strategies that can have a significant impact on public health.

Title: The Impact of Early Childhood Education on Academic Achievement

Education is a fundamental right for all children, and quality early childhood education (ECE) has been shown to have a significant impact on a child’s academic achievement. Research indicates that children who participate in high-quality ECE programs perform better in school, have better social skills, and are more likely to graduate from high school and attend college. However, not all children have access to high-quality ECE programs, and there is a significant achievement gap between children from low-income families and their peers. This research paper aims to explore the impact of early childhood education on academic achievement, with a focus on the factors that contribute to successful ECE programs and how to ensure that all children have access to high-quality ECE. The research problem is the achievement gap between children from low-income families and their peers, and the research objectives are to identify the characteristics of effective ECE programs, examine the impact of ECE on academic achievement, and explore policies that promote access to high-quality ECE for all children. By understanding the impact of early childhood education on academic achievement, this research can inform policies and practices that promote equity and opportunity for all children.

Note: In both examples, the introduction is written in a single paragraph, however, there is no hard and fast rule about how many paragraphs a research paper introduction should be written in. Some introductions can be effectively written in a single paragraph, while others may require more than one paragraph to adequately introduce the topic and set the stage for the research.

The most important consideration is to ensure that the introduction is clear, concise, and effectively sets up the research to follow. If that can be accomplished in a single paragraph, then that is perfectly acceptable. However, if multiple paragraphs are necessary to fully introduce the topic and research objectives, then that is also acceptable.

Ultimately, the length and structure of the introduction should be determined by the needs of the research and the expectations of the target audience.

Things to Keep in Mind

Before starting to write the introduction of a research paper, here are some things to keep in mind:

  • Understand the assignment requirements: Make sure you fully understand the assignment requirements and guidelines for the research paper, including the required length, format, and citation style.
  • I dentify your audience: Consider who your target audience is and what they are expecting to learn from your research paper. This will help you tailor your introduction to meet their needs.
  • Conduct thorough research: Before writing the introduction, ensure that you have conducted thorough research on the topic. This will help you understand the background and context of the research and provide a strong foundation for your introduction.
  • Develop a clear thesis statement: Your thesis statement is the backbone of your research paper and should be clear, concise, and specific. Develop a strong thesis statement that sets the tone for the rest of the paper.
  • Create an outline: An outline can help you organize your thoughts and ideas, and ensure that your introduction flows smoothly and logically.
  • Write a draft: Once you have conducted research and created an outline, write a draft of your introduction. This will help you refine your ideas and identify any areas that need further development or clarification.
  • In-text citations: It’s important to keep in mind the need for accurate and consistent in-text citations while writing the introduction and throughout your paper. Make sure to properly cite any sources you use, including direct quotes, paraphrased information, and any ideas or data that you have used. This not only ensures that you give credit where it is due, but it also helps to strengthen the credibility of your research.
  • Revise and edit: After writing a draft of your introduction, revise and edit it to ensure that it is clear, concise, and effective. Make sure that the language and tone are appropriate for your audience, and that all necessary information is included.

How to Write a Research Paper Introduction?

After writing your research paper, you will have a broad picture of your entire research and analysis. Being an expert in the research niche of your scientific paper , you will be able to come to valid conclusions and highlight your work's main points. This will help you to create an outline, identify the key notions, and include them in the introduction. You should also define a hook that can catch the reader to increase interest in reading your project.

However, the problem with writing the first section is the difficulty in determining the importance of information. While investigating, you will probably feel that all the data you provide is essential. But to write a good introduction, you need to be concise. Your general erudition of background information, combined with specific knowledge of the general subject area, will help you write a great introduction. There are a few simple guides that can help to make your research paper introduction shine:

1. State Your Research Theme

The first sentences should be common about the general topic, and then you should add some details about your topic. This is called the "inverted triangle" when you start a research paper with a broad theme and then narrow it down. Be concise in your presentation of the research problem to avoid any kind of ambiguity. Your study should be presented as a direct continuation of the introduction. It is crucial to keep the narrative logical.

2. Be Original

If you write a dissertation paper in humanities, you can start the introduction with a quotation or even an anecdote. If your academic area is science or medicine, you can write extremely interesting data or even shocking statistics. Such an approach will help you develop an attractive research paper introduction. However, be careful with fact-checking and sources. All the statistics you provide must correspond to reality. According to the methodology, shocking research should be done by you or reputable institutions.

3. Explain Key Terms

You should provide a list of the notions you used and the definitions that you based on to avoid reader confusion. In science, there is a phenomenon when one term can have different interpretations due to the background. Whenever you find yourself in trouble, ask us to write my research paper , and we’ll come to help. Moreover, the glossary will show your knowledge level in the scientific context and help expand the audience that your article may be useful to.

4. Size Is Important

It would help if you chose your ideal length for the introduction. It should be short enough to be readable and gain the reader's attention and long enough to explain all the main features of your essay. And, of course, remember that the size of the introduction should be directly proportional to the size of your study. You need to briefly describe the main sections that your subject includes to guide your reader.

5. Refer to the Keywords

The keywords should be used in the introduction to give a general overview of the research questions. These could be separate words or word combinations which describe your topic. This trick aims to write a research paper that is easier to find. In addition, they help the reader quickly understand the direction of your research, showing the problem and the subject of investigation.

6. Follow the Rules of Logic

You should be consistent in the writing process. As we mentioned in one of the other sections, your work must be holistic. Each new thought should be a continuation of the previous one. A well-elaborated outline may help in solving this research problem. The first passage should logically introduce the reader to the subject and also give a preview of what will be described next. Logical links between sentences will make your text coherent.

An introduction paragraph of a research paper is essential for readers to get an overall idea of the paper. It helps grab their interest and gives them an understanding of the content’s purpose. Writing an informative and catchy introduction can be difficult, but hiring professional nursing essay writers can help remove the burden. They can provide an excellent introduction that introduces the topic in a detailed and easy-to-understand manner.

Common Mistakes and How Not to Slip Up

As you can already understand, writing a decent introduction is quite difficult. You should keep in mind the purpose of your university research to stay on the topic. We are going to see the most common research problem to be aware of when writing.

  • An extended introduction

When you conduct scientific research, each word you write carries a large amount of necessary information. However, working out a quality introduction, you find that the size is very limited, and you need to spend time filtering unnecessary information.

  • Lack of a hook

Good introductions are not limited to just a list of data you have received. It is this paragraph that presents the first impression. Try to make it informative and catchy. If you face some problems elaborating witty hooks for a paper, consult a  writing service that can provide you with professional advice.

  • Inconsistent Data

The problem of inconsistency in the presentation of information appears when you first write the introduction and then the main body of the study. To avoid the error of lack of previous research, follow our advice. Study the background of the hypothesis you have chosen and then describe the results of your research.

Research Paper Introduction Examples

The theory is good, but the practice is quite different. Read our examples to get good ideas from other researchers about how to write an excellent structure and introduction.

Contemporary literary marketing has become digital because of the demands of the online era. Popular best-selling authors such as J. K. Rowling or Dan Brown profit from the internet and use it as a source for advertising to show the audience their creations. On the other hand, many writers find digital literature harmful and destructive for their livelihood because many users can get their books without paying for them. However, more studies reveal that the business side of the book industry is not far from the negative. This research paper will define whether the culture of digital book consumption has to be changed due to the creations of writers becoming worthless due to online piracy and because people have stopped valuing non-digitized books.

The second sample of the introduction paragraph is on the topic: “Behavioral Study of the Phenomenon of Obedience.”

Modern theories tend to associate misbehavior and intentional actions that harm others with personal characteristics. The psychologists and doctors in a survey predicted that only a small portion of people (about 1-3%) would intentionally harm someone after being told to do so. A good example of this phenomenon is a recent war trial with Adolph Eichmann, who claimed he was only following orders to carry out Nazi war crimes. Therefore, is it possible that people can harm others by only “following orders?” Are people capable of betraying their moral convictions if ordered to do so? During the experiment, we will see whether someone can continue administering painful electric shocks that harm another person simply because he or she is told to do so. It is expected that very few will continue and that most of the participants will not obey the order.

Writing an engaging introduction is equally important as conducting research papers or providing a high-quality context for your issue. In fact, a great intro is even more important for your success! An opening paragraph that attracts attention and keeps the reader engaged is the key to success with this academic work.

The intro is the first thing that a reader sees. It is exactly what helps them get the first impression of your work, which carries their opinion about the merits of your paper while they finish reading it. That’s why it’s so important to get it done right.

How do you create flawless intros for your research papers? These tips and examples in this article should help you deal with this assignment effortlessly while avoiding common mistakes. However, it also requires practice. We encourage students to practice writing as much as they can master these skills and never face difficulties with writing academic papers again!

Research Paper Introduction Example: Academic Writing Insight

How to write an introductory paragraph for research paper.

The writing of the research paper is a multi-aspect process. Because this type of academic assignment consists of several parts. If you fail to complete one of the levels, you will fail the whole paper.

Introduction is not a Literal Beginning

As you know, the hardest part is just to begin the paper. And what should do student at the beginning? Not writing an outline. And not working on the introduction. He should make massive research on his topic . You cannot start writing an introduction without having a personal view on the issue that you are going to study. You have to prepare for introduction writing though analyzing facts available online and making notes. If it’s hard to do it yourself, the  online essay help service by will solve this problem instantly!

Why do We Need an Introduction?

The key aim of the introduction is to introduce to the reader the purpose of your research. Just imagine any academic writing starting from the main body section. You cannot pour on the reader your evidence, ideas, and arguments without an explanation of what are you writing about. In the introduction, you must clearly indicate the hypothesis you want to prove or deny. You must explain the necessity of your research, its urgency, and significance for your study, and, finally, hook readers to continue reading it!

What Information Can I Get From my Search for the Introduction?

It depends on the discipline you are writing the research paper on. If your field of study is Humanities, it is likely that you can find a relevant quote, aphorism, or anecdote to introduce your topic to the reader. In case you study tech, social, and medical sciences quotes are irrelevant. More precise and specific facts will fit such an introduction. There is a general rule for all specialties too. You must find a fact that will intrigue a reader. You must hook him.

Attract the Reader in Any Case

Imagine that your research paper is a product that you want to sell and be paid for it. Figuratively, it is true because your aim is to be rewarded with high mark. The first thing salesmen do to sell their product is a promotion of it. They put effort into and use various methods to hook clients. So, what should research paper writers  do to attract a reader? Even if you write a research paper, and the style of writing is formal, it is still necessary and possible to draw his attention. For example, your research paper topic is “How has the music industry been affected by the internet and digital downloading?”. After a hasty internet search, you can find out that there are many legendary musicians like Radiohead that gave up being dependent on music labels and started to issue their LPs by themselves, online. Also, there is a site Pledge Music which is a popular crowdfunding platform for modern musicians. Such popular synth-pop band as IAMX raises money there to record and promote their albums. These two facts prove that digital downloading somehow affects the music industry, and it is urgent to research this topic to learn the character of this effect.

Writing a Thesis Statement

Research paper writing is one of the most challenging tasks for students. To write your research papers in a relevant way, it is important to add new information and to connect the text with the research topic. For example, a research paper introduction example can help you learn how to create an introduction that grabs the attention of the reader. The introduction should not only explain the topic but should also provide enough detail to set up the body of the paper. This can be done by providing background information, presenting a hypothesis, or discussing existing research on the topic. Adding new information will make the introduction more interesting and will lead the reader to the body of the paper.

What do you feel when you watch a good teaser for the movie? You feel hooked, intrigued, and eager to watch the story till the end. The same result you must achieve with the thesis statement in a research paper. You must indicate the highlights of your essay, and leave an open question, a mystery, which the reader will want to learn for sure. To provide a worthy example of a research paper thesis statement let’s return to the discussed above topic “How has the music industry been affected by the internet and digital downloading?”. A thesis statement is a point that you will have to defend. It mandatorily must not be general. For example, if you declare this statement during the conversation, it will surely provoke a conflict and make all people differ in their attitude and take a side. Wrong way: “Downloading music from the internet is bad and we must fight it.” It leaves too many questions to answer. And this statement is way too objective, it does not reflect the controversy of your topic. The truth is that there are no absolutely good or totally bad phenomena. And your thesis statement must show the reality.

Right way: “The culture of digital music consumption must be changed because the creations of musicians become worthless due to activity of web pirates and people stop valuing music according to its merit .”

In this example of thesis, I’ve narrowed my argument to the consequences of digital music downloads on the culture of music consumption. I’ve also focused on the fact that the main harm to the music industry present web pirates.  It induces readers to assume that I will argue against them in the main body. To check if you have created a debatable thesis statement for the research paper, you must figure out whether it is debatable. It means that you must make the reader argue either for or against this statement. Wrong way : “The music industry has changed because of the era of the internet.” It is a statement, but not a thesis statement. It is a general truth. There is no point to argue with that fact. You can narrate about that, but not argue and make research to provide proper evidence to prove your point.

Right way: “Free music download sites must become commercial because recording a music is a full-time job of musicians and every work must be rewarded.” Now it is debatable. Opponents can argue that product that music product is not principal way to earn money for musicians, and internet is a the most effective way to promote their creation and lure audience to visit their concerts, what is a real way to earn money.

Research paper Introduction Writing Tips

Research paper introduction is an essential part of your writing and it must be created according to certain rules. It is true that when you write any kind of text you can push yourself too hard and cross the borders of norms. Because academic styles of writing are referred to as creative writing as well. You look for information, then analyze it, come up with thoughts, and ideas, and reflect it in a coherent text. The next tips will show you how to fulfill the purpose of the research paper introduction and get rid of the creative mess.

  • Size matters. Before a tutor starts reading the article, he reviews it visually. If the size of the introduction is too large, it will make a bad impression on your paper. Just remember, all you have to present in the introduction is: the definition of the topic idea and its urgency, an explanation of the aim of the research, facts to hook the reader, and a thesis statement.
  • Be logical. Your introduction will be really strong if it contains key ideas only in a few sentences. To reach such a result it is important to satisfy the logical connection of the thoughts. Your goal is to make the reader understand in the end of the introduction what exactly you attempted to achieve in a research paper and why this problem is worth profound research.
  • Make it the last part. Many successful students first work on the whole outline, write the body of the paper and only then form the introduction. That’s because a person becomes more sure in what direction his research goes only after at least a shallow search and analysis of sources.
  • Review previous studies on your topic. Every person can study the same topic in a different way. Before you start your own research, you must become aware of the discoveries other scholars made on this issue. Any result will be a reliable background for future work. Note that it is better to indicate recent developments in the primary research rather than a lengthy report.

introduction paragraph example for research paper

Research Paper Introduction Example

Finally, when we have analyzed all highlights of introduction writing we can gather all parts of it in one, ultimate part of a paper. Let’s refresh the exemplary topic of it:  “How has the music industry been affected by the internet and digital downloading?”. Now, have a look at the research paper introduction example: “The musical marketing turns to be digital according to demands of current online epoche. Such underground, but worldwide famous bands like Radiohead and IAMX gain profit from the internet and use it as a primary source to show the audience their creation. On the other hand, many artists find the digital era harmful and destructive to their creativity because there are many sites that offer their products for free, giving no profit to the creator. Currently, there are more and more studies that reveal the business side of the music industry is far from the positive side. This research paper will define whether the culture of digital music consumption must be changed because the creations of musicians become worthless due to the activity of web pirates and because people have stopped valuing music according to its merit.”

As you see, all main components are preserved in the example above. The first sentences hook readers, the mid part of the introduction prove the reason for the research, and the thesis statement puts a debatable argument that needs further analysis and the right solution.

Integrity is a Key

After you created the final paper, be decisive to make necessary changes and corrections, especially before the submission. It usually happens that at the end of the research, a writer can face with inconsistencies in all sections of his writing. If the whole paper does not sound like a cohesive text, make improvements. If your main part does not answer the question raised in the introduction nothing obstructs you from adjusting its sense to the ideas from the main body. A paper with cohesive text deserves a high mark, so rule your writing!

Now You’re a Winner

I suppose that before you came across this article you underestimated the value of a worthy introductive paragraph. In fact, I have not introduced you to another meaningful feature of it. You know that all academic essays must end with a conclusive paragraph. There is an assumption that this is the hardest part of research paper completion. In fact, if you have succeeded in making of impressive introduction, you will significantly facilitate the process of conclusion writing. You don’t think it is easy for you? Ask professionals “ write an essay for me ” because writing your essay does not have to be a difficult job.

introduction paragraph example for research paper

Writing an Introduction for a Scientific Paper

Dr. michelle harris, dr. janet batzli, biocore.

This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study question , biological rationale, hypothesis , and general approach . If the Introduction is done well, there should be no question in the reader’s mind why and on what basis you have posed a specific hypothesis.

Broad Question : based on an initial observation (e.g., “I see a lot of guppies close to the shore. Do guppies like living in shallow water?”). This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study. Broad questions are not always included in your written text, but are essential for establishing the direction of your research.

Background Information : key issues, concepts, terminology, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies. Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. (e.g., “No studies to date have examined whether guppies do indeed spend more time in shallow water.”)

Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. (e.g., “Do guppies spend different amounts of time in water <1 meter deep as compared to their time in water that is >1 meter deep?”)

Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing. The “BR” provides the logic for your hypothesis and experimental approach, describing the biological mechanism and assumptions that explain why your hypothesis should be true.

The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works. If you have written your biological rationale, your reader should see your hypothesis in your introduction section and say to themselves, “Of course, this hypothesis seems very logical based on the rationale presented.”

  • A thorough rationale defines your assumptions about the system that have not been revealed in scientific literature or from previous systematic observation. These assumptions drive the direction of your specific hypothesis or general predictions.
  • Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful. It may help to think about the rationale as an answer to the questions— how is this investigation related to what we know, what assumptions am I making about what we don’t yet know, AND how will this experiment add to our knowledge? *There may or may not be broader implications for your study; be careful not to overstate these (see note on social justifications below).
  • Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
  • Be open to the possibility that as you work with and think about your data, you may develop a deeper, more accurate understanding of the experimental system. You may find the original rationale needs to be revised to reflect your new, more sophisticated understanding.
  • As you progress through Biocore and upper level biology courses, your rationale should become more focused and matched with the level of study e ., cellular, biochemical, or physiological mechanisms that underlie the rationale. Achieving this type of understanding takes effort, but it will lead to better communication of your science.

***Special note on avoiding social justifications: You should not overemphasize the relevance of your experiment and the possible connections to large-scale processes. Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. Performing an investigation just for the sake of adding to our scientific knowledge (“pure or basic science”) is just as important as applied science. In fact, basic science often provides the foundation for applied studies.

Hypothesis / Predictions : specific prediction(s) that you will test during your experiment. For manipulative experiments, the hypothesis should include the independent variable (what you manipulate), the dependent variable(s) (what you measure), the organism or system , the direction of your results, and comparison to be made.

If you are doing a systematic observation , your hypothesis presents a variable or set of variables that you predict are important for helping you characterize the system as a whole, or predict differences between components/areas of the system that help you explain how the system functions or changes over time.

Experimental Approach : Briefly gives the reader a general sense of the experiment, the type of data it will yield, and the kind of conclusions you expect to obtain from the data. Do not confuse the experimental approach with the experimental protocol . The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section.

Some Final Tips on Writing an Introduction

  • As you progress through the Biocore sequence, for instance, from organismal level of Biocore 301/302 to the cellular level in Biocore 303/304, we expect the contents of your “Introduction” paragraphs to reflect the level of your coursework and previous writing experience. For example, in Biocore 304 (Cell Biology Lab) biological rationale should draw upon assumptions we are making about cellular and biochemical processes.
  • Be Concise yet Specific: Remember to be concise and only include relevant information given your audience and your experimental design. As you write, keep asking, “Is this necessary information or is this irrelevant detail?” For example, if you are writing a paper claiming that a certain compound is a competitive inhibitor to the enzyme alkaline phosphatase and acts by binding to the active site, you need to explain (briefly) Michaelis-Menton kinetics and the meaning and significance of Km and Vmax. This explanation is not necessary if you are reporting the dependence of enzyme activity on pH because you do not need to measure Km and Vmax to get an estimate of enzyme activity.
  • Another example: if you are writing a paper reporting an increase in Daphnia magna heart rate upon exposure to caffeine you need not describe the reproductive cycle of magna unless it is germane to your results and discussion. Be specific and concrete, especially when making introductory or summary statements.

Where Do You Discuss Pilot Studies? Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.

How to Start a Research Paper

introduction paragraph example for research paper

Beginning is always the hardest part of an assignment. The introduction should not be the first thing you begin to write when starting to work on an essay. First, tons of research should be conducted — in order for your paper to be good. Only then you will be able to extract the main points of your work, and introduce them to your readers. A good introduction will also include your personal opinion of the problem, and, therefore, will make the writing easier overall. Let's dive into the details with admission essay writing services .

What Is a Research Paper?

A research paper is a type of writing in which the author does an independent analysis of the topic and describes the findings from that investigation. Furthermore, one will have to identify the weaknesses and strengths of the subject and evaluate them accordingly.

Don't Know How to Start Your Research Paper?

Head on over to Pro. Our research paper writing service can assist you with writing and polishing up any of the work that you write.

A good way to write an introduction for a research paper is to introduce your reader to the topic by telling them what you are writing about. Then, make sure you include an interesting fact, or some surprising statistical data, so that your reader will be hooked and will continue to read your research paper. Treat your essay introduction like an advertisement for a product you want to sell—if your advertisement is bad, the sales won’t be great. The same goes for a bad introduction; if it does not intrigue readers, they might lose interest in your paper.

The beginning is always the hardest part of an assignment. Regardless of if you are writing a small resume education section or a full-blown research paper - following the correct steps is very important . The introduction should not be the first thing you begin to write when starting to work on an essay.

Present Your Essay Topic

The base of every essay is its topic. What you are writing about should always be a reflection of your topic. Simply start off your introduction by telling your readers, in a simple and accessible language, what it is you are writing your research paper about. Although, we suggest you include a “trigger” when introducing the topic of your paper. A personal reference, or a story that relates to the essay topic, are options for a good way to link plain text to people’s emotions. So, feel free to write sincerely, as if you were talking to a friend.

The best strategy to start your introduction is by writing a broad topic presentation, then gradually narrow it down to what you would like to focus on exactly. It will put your topic into perspective for readers’ general understanding. When writing your research paper, make sure to include your opinion on the issue in your introduction. This will make your topic sound more personal and it will likely become more important to your audience as well.

Provide Background Information and Context

The topic you begin writing about is likely very familiar to you, as it is expected that you have done plenty of research. But what about your readers? For the most part, the amount of context is determined by what your audience already knows—though, let’s focus on a bigger assortment of readers, to make sure everyone’s needs are met. Imagine that you are part of your audience. Read the information you provided in the introduction. Is this sufficient? Does it leave gaps and unanswered questions in your research? Your job as a writer is to provide the perfect background to your topic, which gives readers just enough information to be able to grasp your topic and enjoy your research paper to the fullest. Another extreme you should avoid is giving too much context—consequently making the audience feel bored right from the introduction. Write your essay as something that you would enjoy reading yourself, like a story, but not an academic research paper.

Explain the Importance of Your Research

There is no doubt that after plenty of research you are an expert in your field. But what about your readers? In the introduction you need to showcase the extent of your research and write about the work you have completed. This will also help your readers understand that your ideas are supported by other scholars, and you share their views in your paper.

Make sure to write about all the works you have studied in order to persuade readers of your expertise. For your introduction, simply use the names you are referencing, or their most important works, so that the audience does not feel overwhelmed. It is also necessary to cite all your sources—in order to avoid academic plagiarism.

Make Your Rationale Work

Rationale is the most important part of the beginning of your paper. Explain to readers the reasoning behind your research paper—the importance of this is a guarantee that they will keep reading and appreciate your topic. In the introduction, you need to write an explanation of how your paper fits into all the research that has already been done in that field; this shows your audience the importance of your essay and the role your research plays in the field overall.

Show the Significance of Your Research

You, and only you, understand how important your research is. The next step of your introduction is to prove to your audience how important it is. Include the basic, and the most important literature, you support your ideas with. This will show the readers your solid analytical skills, your writing capabilities, and your ability to sort out information to deliver the most important points for your paper. And the final part of the introduction is to simply explain why your research is important to the field, to society, to the whole world, and, most importantly, to the readers. When a person can relate to an idea, it is almost always a guarantee that your argument will be persuasive and have a positive outcome.

Make Sure Your Thesis Is Clear

A research paper introduction uses primary sources and data to support its thesis statement. A research paper’s thesis statement has a lot in common with a thesis for an essay, or other non-research assignment. The difference lies in the fact that in a research thesis, you gather evidence from valid sources to prove your perspective on a topic. Despite the fact that you support your thoughts by sources, the idea for your thesis in your introduction should be original and your own, as it reflects the way you think. ‍

If you wonder how to start a thesis statement for a research paper, we have A FULL GUIDE

Here is a quick checklist for writing a thesis statement:

  • Remember, the thesis is your argument. Make sure it sounds assertive.
  • Write two to three versions of your thesis and choose the best one.
  • Share your thesis with a neutral person—to get a different point of view.
  • Discuss your thesis with others; they might have good ideas as well.
  • It should appear in your introduction, and be restated in your conclusion.

Research Paper Title Page

Mla title page.

Here are some tips from our writing team on how to format your research paper MLA title page:

  • The title page is double spaced and the text needs to be centred.
  • Write the name of your university or college.
  • Skip about one-third of the page down and type your research paper title—include a subtitle if you have one.
  • Skip several lines down and type your name, your course name and number, your instructor’s name, and your paper’s due date.


APA Title Page

  • Place a running head in your page’s header:
  • Use the label “Running head:” then, put your shortened title (IN UPPERCASE LETTERS), and align it all to the left.
  • Place the page number in this same header, but align it to the right, and begin with page number 1.
  • The header should be 1 inch from the top. Some teachers say 1/2 inch is okay as well.
  • Place your paper’s title in the upper half of the page, centred. Capitalize the first letter of all of the important words in your title.
  • Place your University’s name below your name, double-spaced.

Research Paper Introduction Example

Now that you have a solid idea about the introduction of a research paper, let’s take a look at some examples from our writers. They will help you see how all of the rules we presented above work in practice. ‍

Research Paper Introduction Example: Should Parents Be Held Accountable for the Criminal Acts of Their Children? Recently, youth gang connected attacks have been occurring in an increasing prevalence, with some even causing deaths, such as the killing of a college student at Suburbs East. Such occurrences have made a lot of people to wonder about the origin of those violent actions, with much of the extent of guilt being put on the parents of such adolescents. In any event, one has to question whether the parents should be penalized for the offenses of their kids. Some people believe that parents should be held responsible for the criminal acts of their offspring because parents are mostly accountable for the education and upbringing of their kids, and frequently impact the actions and behavior of their children until they become mature and independent. This is because they are almost always the ones that raise their kids after birth. As such, it is believed that parents start to influence the ethical range of their children from a young age, and one’s ethics are critically impacted by the way parents act and their personalities (Gratz, 169). This logic can make parents responsible for their children if they do wrong later on — because they are understood to not have raised their child in the right way. Furthermore, there is an argument that children are virtually completely controlled by their parents, as they are apt to want to make their parents happy, and they would, therefore, listen to whatever they are told to do or how they are told to behave (Michael, Andrew and Michael, 4). This, in turn, makes many people think that parents should always be the ones to be blamed for the criminal acts of their children, as they believe that they have the power to warn and control them.
