Writing a Research Paper Introduction | Step-by-Step Guide
Published on September 24, 2022 by Jack Caulfield . Revised on March 27, 2023.
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:

Professional editors proofread and edit your paper by focusing on:
- Academic style
- Vague sentences
- Style consistency
See an example
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 …

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.

How to write an introduction for a research paper
Beginnings are hard. Beginning a research paper is no exception. Many students—and pros—struggle with how to write an introduction for a research paper.
This short guide will describe the purpose of a research paper introduction and how to create a good one.
What is an introduction for a research paper?
Introductions to research papers do a lot of work.
It may seem obvious, but introductions are always placed at the beginning of a paper. They guide your reader from a general subject area to the narrow topic that your paper covers. They also explain your paper’s:
- Scope: The topic you’ll be covering
- Context: The background of your topic
- Importance: Why your research matters in the context of an industry or the world
Your introduction will cover a lot of ground. However, it will only be half of a page to a few pages long. The length depends on the size of your paper as a whole. In many cases, the introduction will be shorter than all of the other sections of your paper.

Why is an introduction vital to a research paper?
The introduction to your research paper isn’t just important. It’s critical.
Your readers don’t know what your research paper is about from the title. That’s where your introduction comes in. A good introduction will:
- Help your reader understand your topic’s background
- Explain why your research paper is worth reading
- Offer a guide for navigating the rest of the piece
- Pique your reader’s interest
Without a clear introduction, your readers will struggle. They may feel confused when they start reading your paper. They might even give up entirely. Your introduction will ground them and prepare them for the in-depth research to come.
What should you include in an introduction for a research paper?
Research paper introductions are always unique. After all, research is original by definition. However, they often contain six essential items. These are:
- An overview of the topic. Start with a general overview of your topic. Narrow the overview until you address your paper’s specific subject. Then, mention questions or concerns you had about the case. Note that you will address them in the publication.
- Prior research. Your introduction is the place to review other conclusions on your topic. Include both older scholars and modern scholars. This background information shows that you are aware of prior research. It also introduces past findings to those who might not have that expertise.
- A rationale for your paper. Explain why your topic needs to be addressed right now. If applicable, connect it to current issues. Additionally, you can show a problem with former theories or reveal a gap in current research. No matter how you do it, a good rationale will interest your readers and demonstrate why they must read the rest of your paper.
- Describe the methodology you used. Recount your processes to make your paper more credible. Lay out your goal and the questions you will address. Reveal how you conducted research and describe how you measured results. Moreover, explain why you made key choices.
- A thesis statement. Your main introduction should end with a thesis statement. This statement summarizes the ideas that will run through your entire research article. It should be straightforward and clear.
- An outline. Introductions often conclude with an outline. Your layout should quickly review what you intend to cover in the following sections. Think of it as a roadmap, guiding your reader to the end of your paper.
These six items are emphasized more or less, depending on your field. For example, a physics research paper might emphasize methodology. An English journal article might highlight the overview.
Three tips for writing your introduction
We don’t just want you to learn how to write an introduction for a research paper. We want you to learn how to make it shine.
There are three things you can do that will make it easier to write a great introduction. You can:
- Write your introduction last. An introduction summarizes all of the things you’ve learned from your research. While it can feel good to get your preface done quickly, you should write the rest of your paper first. Then, you’ll find it easy to create a clear overview.
- Include a strong quotation or story upfront. You want your paper to be full of substance. But that doesn’t mean it should feel boring or flat. Add a relevant quotation or surprising anecdote to the beginning of your introduction. This technique will pique the interest of your reader and leave them wanting more.
- Be concise. Research papers cover complex topics. To help your readers, try to write as clearly as possible. Use concise sentences. Check for confusing grammar or syntax . Read your introduction out loud to catch awkward phrases. Before you finish your paper, be sure to proofread, too. Mistakes can seem unprofessional.

10 tips for writing an effective introduction to original research papers
After the title and abstract, the introduction is the next thing your audience will read, so it's vital to begin strongly. The introduction is your opportunity to show readers and reviewers why your research topic is worth reading about and why your paper warrants their attention.
The introduction serves multiple purposes. It presents the background to your study, introduces your topic and aims, and gives an overview of the paper. A good introduction will provide a solid foundation and encourage readers to continue on to the main parts of your paper—the methods, results, and discussion.
In this article, we present 10 tips for writing an effective introduction. These tips apply primarily to full papers and letters reporting original research results. Although some tips will be more suited to papers in certain fields, the points are broadly applicable.
1. Start broadly and then narrow down
In the first paragraph, briefly describe the broad research area and then narrow down to your particular focus. This will help position your research topic within the broader field, making the work accessible to a broader audience, not just to specialists in your field.
2. State the aims and importance
Papers rejected for "not showing the importance of the topic" or "lacking clear motivation" usually neglect this point. Say what you want to achieve and why your reader should be interested in finding out whether you achieve it. The basic structure can be as simple as "We aim to do X, which is important because it will lead to Y."
3. Cite thoroughly but not excessively
Instead of simply saying that the topic is important, show why the topic is important .
Once you've narrowed your focus to the specific topic of your study, you should thoroughly cover the most recent and most relevant literature pertaining to your study. Your review of the literature should be complete, but not overly long— remember, you're not writing a review article . If you find that your introduction is too long or overflowing with citations, one possible solution is to cite review articles, rather than all the individual articles that have already been summarized in the review.
4. Avoid giving too many citations for one point
Consider the following sentence: "Many studies have found a significant association between X and Y [4-15]." This sentence cites too many studies at once. Although references [4-15] might provide a good overview of the topic, this sentence doesn't provide enough context or explanation for these past studies. If all of these references are worth citing, they should be discussed in greater specificity. For example, "A significant association has been found between X and Y in men [4-7], women [8-11], and children [12-15]."

5. Clearly state either your hypothesis or research question
For research in empirical sciences, stating a hypothesis can be an effective way of framing the research. For example, instead of stating "In this study, we show that X is related to Y by method A," you could say, "In this study, we hypothesize that X is related to Y, and we use method A to test this hypothesis." For research in formal sciences or exploratory research, you could consider stating a research question instead: "In this study, we examine the following research question: Is X related to Y?" Note that the research question doesn't always have to be stated in the interrogative form (with a question mark); instead, you can put the question into a declarative sentence: "In this study, we investigate whether X is related to Y." Hypotheses and research questions are effective because they help give shape to the paper and serve as "signpost phrases" that guide readers through your paper smoothly.
6. Consider giving an overview of the paper
Example structure of an introduction
- Give a general introduction to the topic for broad audience
- Narrow the focus to your particular topic
- State your research problem and aims
Literature review (usually several paragraphs):
- Summarize the relevant literature on your topic
- Describe the current state of the art
- Note any gaps in the literature that your study will address
Research targets (usually one paragraph):
- State your hypothesis or research question
- Briefly describe how you will accomplish your aims
- Give a preview of your main results and state the contribution of the work (optional)
Paper overview (optional; one paragraph):
- Give a section-by-section overview of the paper's contents
An organizational overview is more common in some fields than others. It is particularly common in technology, but less so in medicine. In the last paragraph of your introduction, consider giving a section-by-section overview of your paper if it is appropriate for your field. For example, "In Section II, we describe our analysis methods and the datasets we used. In Section III we present the results. In Section IV, we discuss the results and compare our findings with those in the literature. In Section V, we state our conclusions and suggest possible topics for future research."
7. Keep it short
Try to avoid an overly long introduction. A good target is 500 to 1000 words, although checking the journal's guidelines and past issues will provide the clearest guidance.
8. Show, don't tell
One goal of the introduction is explaining why your research topic is worthy of study. One of the most common pitfalls is to simply say, "Subject X is important." Instead of simply saying that the topic is important, show why the topic is important . For example, instead of writing "The development of new materials is important for the automotive industry," you could write, "The development of new materials is necessary for the automotive industry to produce stronger, lighter vehicles, which will improve safety and fuel economy ."
9. Don't bury your readers in detail
In the introduction, if your paper is in a field that commonly summarizes the study's main results before starting the methods, you should avoid stating too many detailed results because these results need the development in the other sections of your paper to be properly understood. Instead of saying "We find that our algorithm requires 55% of the memory and 45% of the computation time of the conventional algorithm," it is usually better to give a general overview of the findings in the introduction: "Here we compare the proposed algorithm with a conventional algorithm in terms of memory use and computational speed, showing that the proposed algorithm is both smaller and faster ." Some older style guides suggest holding back the main result to build suspense, but now journals in many fields— medicine being a notable exception —encourage giving a preview of your main results in the introduction.
10. Check the journal requirements
Many journals have specific requirements for the introduction in their guidelines for authors. For example, there might be a maximum word count stated or the guidelines might require specific content, such as a hypothesis statement or a summary of your main results.
I would like to close with one last piece of advice: When you begin drafting a paper, the introduction should be one of the first things you plan . The introduction serves as the roadmap for your paper; by clearly stating the study's background, aims, and hypothesis/research question, the introduction can guide you as you write the rest of the paper. It's such an important section—setting the scene for everything that follows—that many authors write the methods, results, and discussion sections in full before completing the introduction.

How to Write a Research Paper Introduction
As the saying goes, You only get one chance at a first impression, and research papers are no exception. It’s the first thing people read, so a solid research paper introduction should lay the groundwork for the rest of the paper, answer the early questions a reader has, and make a personal impact—all while being as succinct as possible.
It’s not always easy knowing how to write introductions for research papers, and sometimes they can be the hardest part of the whole paper. So in this guide, we’ll explain everything you need to know, discussing what to include in introductions to research papers and sharing some expert tips so you can do it well.

What is a research paper introduction?
A research paper introduction is an essential part of academic writing that explains the paper’s main topic and prepares the reader for the rest of the paper. After reading the introduction, the reader should know what the paper is about, what point it’s trying to make, and why it matters.
For scientific and data-heavy research papers, the introduction has a few more formal requirements, such as briefly describing how the research was conducted. We’ll explain more on those in the next section.
The role of the research paper introduction is to make sure the reader understands all the necessary preliminary information before they encounter the discoveries presented in the body of the research paper. Learning how to write an introduction is an important part of knowing how to write a research paper .
How long should a research paper introduction be?
There are no firm rules on how long a research paper introduction should be. The only guideline is that the length of the introduction should be commensurate with the length of the entire paper. Very long papers may have an introduction that spans more than one page, while short papers can have an introduction of only a paragraph.
What to include in introductions to research papers
Generally speaking, a good research paper introduction includes these parts:
1 Thesis statement
2 Background context
3 Niche (research gap)
4 Relevance (how the paper fills that gap)
5 Rationale and motivation
First, a thesis statement is a single sentence that summarizes the main topic of your paper. The thesis statement establishes the scope of the paper, defining what will and won’t be discussed.
You also want to provide some background , summarizing what the reader needs to know before you present new information. This includes a brief history of the topic and any previous research or writings that your own ideas are built on.
In academic writing, it’s good to explain the paper’s niche, the area of research that your paper contributes to. In formal research papers, you should describe the research gap, a particular area of a topic that either has not been researched or has inadequate research. Informal research papers without original research don’t need to worry much about this.
After establishing the niche, next you explain how your research paper fills that niche—in other words, your paper’s relevance. Why is this paper important? What does it teach us? In a formal research paper introduction, you explain how your paper and research attempt to close the research gap and add the missing data.
Last, mention the rationale and motivation for why you chose this topic for your research. This can be either a personal choice or a practical one, such as researching a topic that urgently needs new information. You can also mention what you hope your research accomplishes—your goals—to round out your motivations.
What to include in introductions to scientific research papers
Scientific research papers, especially if they present original research and new data, have some additional requirements for their introduction:
- Research question or hypothesis
- Literature review (previous research and current literature)
The methodology describes how you conducted your research, including which tools you used or the procedure for your tests. This is to validate your findings, so readers know your data comes from a reliable source.
A research question or hypothesis acts similarly to the thesis statement. A research question is simply the question your research aims to answer, while a hypothesis is your prediction, made before the experiments begin, of what the research will yield. By the end of the paper, your hypothesis will be proven right or wrong.
Given the nature of scientific papers, the background context is more detailed than in other research papers. A literature review explains all the research on your particular topic that’s relevant to your paper. You outline the major writings and other research papers your own research is based on, and discuss any problems or biases those writings have that may undermine their findings.
The literature review is the perfect place for establishing the research gap. Here you can explain in your own words why the current research on your topic is insufficient, and why your own research serves to fill this gap.
If you’re writing a casual paper that relies only on existing research, you don’t need to worry about these.
How to write introductions for research papers
1 use the cars model.
The English scientist John Swales devised a method known as the CARS model to “Create A Research Space” in introductions. Although it’s aimed at scientific papers, this simple, three-step structure can be used to outline any research paper introduction.
- Establishing a territory : Explain the background context of your topic, including previous research.
- Establishing a niche : Explain that one area of your topic is missing information or that the current research is inadequate.
- Occupying a niche : Explain how your research “fills in” that missing information from your topic.
Swales then suggests stating the outcome of the research and previewing the structure of the rest of the paper, although these don’t apply to all research papers, particularly informal ones.
2 Start broad and narrow down
One common mistake in writing research paper introductions is to try fitting in everything all at once. Instead, pace yourself and present the information piece by piece in the most logical order for the reader to understand. Generally that means starting broad with the big picture, and then gradually getting more specific with the details.
For research paper introductions, you want to present an overview of the topic first, and then zero in on your particular paper. This “funnel” structure naturally includes all the necessary parts of what to include in research paper introductions, from background context to the niche or research gap and finally the relevance.
3 Be concise
Introductions aren’t supposed to be long or detailed; they’re more like warm-up acts. Introductions are better when they cut straight to the point—save the details for the body of the paper, where they belong.
The most important point about introductions is that they’re clear and comprehensible. Wordy writing can be distracting and even make your point more confusing, so remove unnecessary words and try to phrase things in simple terms that anyone can understand.
4 Consider narrative style
Although not always suitable for formal papers, using a narrative style in your research paper introduction can help immensely in engaging your reader and “ hooking ” them emotionally. In fact, a 2016 study showed that, in certain papers, using narrative strategies actually improves how often they’re cited in other papers.
A narrative style involves making the paper more personal in order to appeal to the reader’s emotions. Strategies include:
- Using first-person pronouns ( I, we, my, our ) to establish yourself as the narrator
- Describing emotions and feelings in the text
- Setting the scene; describing the time and place of key events to help the reader imagine them
- Appealing to the reader’s morality, sympathy, or urgency as a persuasion tactic
Again, this style won’t work for all research paper introductions, especially those for scientific research. However, for more casual research papers—and especially essays—this style can make your writing more entertaining or at the very least interesting, perfect for raising your reader’s enthusiasm right at the start of your paper.
5 Write your research paper introduction last
Your introduction may come first in a research paper, but a common tip is to wait on writing it until everything else is already written. This makes it easier to summarize your paper, because at that point you know everything you’re going to say. It also removes the urge to include everything in the introduction because you don’t want to forget anything.
Furthermore, it’s especially helpful to write your introduction after your research paper conclusion . A research paper’s introduction and conclusion share similar themes, and often mirror each other’s structure. Writing the conclusion is usually easier, too, thanks to the momentum from writing the rest of the paper, and that conclusion can help guide you in writing your introduction.
Research paper introduction FAQs
For academic writing like research papers, an introduction has to explain the topic, establish the necessary background context, and prepare the reader for the rest of the paper. In scientific research papers, the introduction also addresses the methodology and describes the current research for that topic.
What do you include in an introduction to a research paper?
A good research paper introduction includes:
- Thesis statement
- Background context
- Niche (research gap)
- Relevance (how it fills that gap)
- Rationale and motivation
Scientific research papers with original data should also include the methodology, a literature review, and possibly a research question or hypothesis.
How do you write an introduction for a research paper?
There are a few important guidelines to remember when writing a research paper. Start with a broad overview of the topic and gradually get more specific with the details and how your paper relates. Be sure to keep your introduction as succinct as possible, as you don’t want it to be too long. Some people find it’s easier to write the introduction last, after the rest of the paper is finished.
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.

- 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.

The introduction serves the purpose of leading the reader from a general subject area to a particular field of research. It establishes the context of the research being conducted by summarizing current understanding and background information about the topic, stating the purpose of the work in the form of the hypothesis, question, or research problem, briefly explaining your rationale, methodological approach, highlighting the potential outcomes your study can reveal, and describing the remaining structure of the paper.

Importance of a Good Introduction
Think of the introduction as a mental road map that must answer for the reader these four 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?
A well-written introduction is important because, quite simply, you never get a second chance to make a good first impression. The opening paragraph of your paper will provide your readers with their initial impressions about the logic of your argument, your writing style, the overall quality of your research, and, ultimately, the validity of your findings and conclusions. A vague, disorganized, or error-filled introduction will create a negative impression, whereas, a concise, engaging, and well-written introduction will start your readers off thinking highly of your analytical skills, your writing style, and your research approach.

Structure and Writing Style
I. Structure and Approach
The introduction is the broad beginning of the paper that answers three important questions for the reader:
- What is this?
- Why am I reading it?
- What do you want me to think about / consider doing / react to?
Think of the structure of the introduction as an inverted triangle of information. Organize the information so as to present the more general aspects of the topic early in the introduction, then narrow toward the more specific topical information that provides context, finally arriving at your statement of purpose and rationale and, whenever possible, the potential outcomes your study can reveal.
These are general phases associated with writing an introduction:
- Highlighting the importance of the topic, and/or
- Making general statements about the topic, and/or
- Presenting an overview on current research on the subject.
- Opposing an existing assumption, and/or
- Revealing a gap in existing research, and/or
- Formulating a research question or problem, and/or
- Continuing a disciplinary tradition.
- Stating the intent of your study,
- Outlining the key characteristics of your study,
- Describing important results, and
- Giving a brief overview of the structure of the paper.
NOTE: Even though the introduction is the first main section of a research paper, it is often useful to finish the introduction very late in the writing process because the structure of the paper, the reporting and analysis of results, and the conclusion will have been completed and it ensures that your introduction matches the overall structure of your paper.
II. Delimitations of the Study
Delimitations refer to those characteristics that limit the scope and define the conceptual boundaries of your study . This is determined by the conscious exclusionary and inclusionary decisions you make about how to investigate the research problem. In other words, not only should you tell the reader what it is you are studying and why, but you must also acknowledge why you rejected alternative approaches that could have been used to examine the research problem.
Obviously, the first limiting step was the choice of research problem itself. However, implicit are other, related problems that could have been chosen but were rejected. These should be noted in the conclusion of your introduction.
Examples of delimitating choices would be:
- The key aims and objectives of your study,
- The research questions that you address,
- The variables of interest [i.e., the various factors and features of the phenomenon being studied],
- The method(s) of investigation, and
- Any relevant alternative theoretical frameworks that could have been adopted.
Review each of these decisions. You need to not only clearly establish what you intend to accomplish, but to also include a declaration of what the study does not intend to cover. In the latter case, your exclusionary decisions should be based upon criteria stated as, "not interesting"; "not directly relevant"; “too problematic because..."; "not feasible," and the like. Make this reasoning explicit!
NOTE: Delimitations refer to the initial choices made about the broader, overall design of your study and should not be confused with documenting the limitations of your study discovered after the research has been completed.
III. The Narrative Flow
Issues to keep in mind that will help the narrative flow in your introduction :
- Your introduction should clearly identify the subject area of interest . A simple strategy to follow is to use key words from your title in the first few sentences of the introduction. This will help focus the introduction on the topic at the appropriate level and ensures that you get to the primary subject matter quickly without losing focus, or discussing information that is too general.
- Establish context by providing a brief and balanced review of the pertinent published literature that is available on the subject. The key is to summarize for the reader what is known about the specific research problem before you did your analysis. This part of your introduction should not represent a comprehensive literature review but consists of a general review of the important, foundational research literature (with citations) that lays a foundation for understanding key elements of the research problem. See the drop-down tab for "Background Information" for types of contexts.
- Clearly state the hypothesis that you investigated . When you are first learning to write in this format it is okay, and actually preferable, to use a past statement like, "The purpose of this study was to...." or "We investigated three possible mechanisms to explain the...."
- Why did you choose this kind of research study or design? Provide a clear statement of the rationale for your approach to the problem studied. This will usually follow your statement of purpose in the last paragraph of the introduction.
IV. Engaging the Reader
The overarching goal of your introduction is to make your readers want to read your paper. The introduction should grab your reader's attention. Strategies for doing this can be to:
- Open with a compelling story,
- Include a strong quotation or a vivid, perhaps unexpected anecdote,
- Pose a provocative or thought-provoking question,
- Describe a puzzling scenario or incongruity, or
- Cite a stirring example or case study that illustrates why the research problem is important.
NOTE: Only choose one strategy for engaging your readers; avoid giving an impression that your paper is more flash than substance.

Avoid the "Dictionary" Introduction
Giving the dictionary definition of words related to the research problem may appear appropriate because it is important to define specific words or phrases with which readers may be unfamiliar. However, anyone can look a word up in the dictionary and a general dictionary is not a particularly authoritative source. It doesn't take into account the context of your topic and doesn't offer particularly detailed information. Also, placed in the context of a particular discipline, a term may have a different meaning than what is found in a general dictionary. If you feel that you must seek out an authoritative definition, try to find one that is from subject specific dictionaries or encyclopedias [e.g., if you are a sociology student, search for dictionaries of sociology].

Another Writing Tip
When Do I Begin?
A common question asked at the start of any paper is, "where should I begin?" An equally important question to ask yourself is, "When do I begin?" Research problems in the social sciences rarely rest in isolation from the history of the issue being investigated. It is, therefore, important to lay a foundation for understanding the historical context underpinning the research problem. However, this information should be brief and succinct and begin at a point in time that best informs the reader of study's overall importance. For example, a study about coffee cultivation and export in West Africa as a key stimulus for local economic growth needs to describe the beginning of exporting coffee in the region and establishing why economic growth is important. You do not need to give a long historical explanation about coffee exportation in Africa. If a research problem demands a substantial exploration of historical context, do this in the literature review section; note in the introduction as part of your "roadmap" [see below] that you covering this in the literature review.
Yet Another Writing Tip
Always End with a Roadmap
The final paragraph or sentences of your introduction should forecast your main arguments and conclusions and provide a description of the rest of the paper [a "roadmap"] that let's the reader know where you are going and what to expect.

Ideally, the Introduction is an essential attention grabbing section of a research paper. If written correctly, the Introduction peaks the reader's interest as well as serves as a roadmap for the rest of the paper. An effective Introduction builds off related empirical research and demonstrates a gap in which the current study fills. Finally, the Introduction proposes the research question(s) which will be answered in subsequent sections of the paper. A strong Introduction also requires the use of a simple and well-organized format as well as the avoidance of common pitfalls.
