How to Write an Abstract | Steps & Examples
Published on February 28, 2019 by Shona McCombes . Revised on July 18, 2023 by Eoghan Ryan.
![how to write an abstract dissertation example How to Write an Abstract](https://www.scribbr.nl/wp-content/uploads/2022/07/How-to-Write-an-Abstract-preview.webp)
An abstract is a short summary of a longer work (such as a thesis , dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.
Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.
One common way to structure your abstract is to use the IMRaD structure. This stands for:
- Introduction
Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.
In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.
This paper examines the role of silent movies as a mode of shared experience in the US during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).
Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.
Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

You will almost always have to include an abstract when:
- Completing a thesis or dissertation
- Submitting a research paper to an academic journal
- Writing a book or research proposal
- Applying for research grants
It’s easiest to write your abstract last, right before the proofreading stage, because it’s a summary of the work you’ve already done. Your abstract should:
- Be a self-contained text, not an excerpt from your paper
- Be fully understandable on its own
- Reflect the structure of your larger work
Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?
You can include some brief context on the social or academic relevance of your dissertation topic , but don’t go into detailed background information. If your abstract uses specialized terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.
After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyze,” or “evaluate” to describe exactly what you set out to do.
This part of the abstract can be written in the present or past simple tense but should never refer to the future, as the research is already complete.
- This study will investigate the relationship between coffee consumption and productivity.
- This study investigates the relationship between coffee consumption and productivity.
Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.
- Structured interviews will be conducted with 25 participants.
- Structured interviews were conducted with 25 participants.
Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.
Next, summarize the main research results . This part of the abstract can be in the present or past simple tense.
- Our analysis has shown a strong correlation between coffee consumption and productivity.
- Our analysis shows a strong correlation between coffee consumption and productivity.
- Our analysis showed a strong correlation between coffee consumption and productivity.
Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.
Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.
- We concluded that coffee consumption increases productivity.
- We conclude that coffee consumption increases productivity.
If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalizability of your research.
If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.
If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.
Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.
It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.
Read other abstracts
The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.
You can also find lots of dissertation abstract examples in thesis and dissertation databases .
Reverse outline
Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.
For each chapter or section, list keywords and draft one to two sentences that summarize the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.
Write clearly and concisely
A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.
To keep your abstract or summary short and clear:
- Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
- Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
- Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
- Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
- Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.
If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services or use the paraphrasing tool .
Check your formatting
If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .
Checklist: Abstract
The word count is within the required length, or a maximum of one page.
The abstract appears after the title page and acknowledgements and before the table of contents .
I have clearly stated my research problem and objectives.
I have briefly described my methodology .
I have summarized the most important results .
I have stated my main conclusions .
I have mentioned any important limitations and recommendations.
The abstract can be understood by someone without prior knowledge of the topic.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:
- To help potential readers determine the relevance of your paper for their own research.
- To communicate your key findings to those who don’t have time to read the whole paper.
Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.
An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.
The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .
Avoid citing sources in your abstract . There are two reasons for this:
- The abstract should focus on your original research, not on the work of others.
- The abstract should be self-contained and fully understandable without reference to other sources.
There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.
The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

Writing an abstract - a six point checklist (with samples)
Posted in: abstract , dissertations
![how to write an abstract dissertation example](https://i0.wp.com/blogs.bath.ac.uk/academic-and-employability-skills/wp-content/uploads/sites/84/2016/06/questions-2245264_1920.jpg?resize=1200%2C678&ssl=1)
The abstract is a vital part of any research paper. It is the shop front for your work, and the first stop for your reader. It should provide a clear and succinct summary of your study, and encourage your readers to read more. An effective abstract, therefore should answer the following questions:
- Why did you do this study or project?
- What did you do and how?
- What did you find?
- What do your findings mean?
So here's our run down of the key elements of a well-written abstract.
- Size - A succinct and well written abstract should be between approximately 100- 250 words.
- Background - An effective abstract usually includes some scene-setting information which might include what is already known about the subject, related to the paper in question (a few short sentences).
- Purpose - The abstract should also set out the purpose of your research, in other words, what is not known about the subject and hence what the study intended to examine (or what the paper seeks to present).
- Methods - The methods section should contain enough information to enable the reader to understand what was done, and how. It should include brief details of the research design, sample size, duration of study, and so on.
- Results - The results section is the most important part of the abstract. This is because readers who skim an abstract do so to learn about the findings of the study. The results section should therefore contain as much detail about the findings as the journal word count permits.
- Conclusion - This section should contain the most important take-home message of the study, expressed in a few precisely worded sentences. Usually, the finding highlighted here relates to the primary outcomes of the study. However, other important or unexpected findings should also be mentioned. It is also customary, but not essential, to express an opinion about the theoretical or practical implications of the findings, or the importance of their findings for the field. Thus, the conclusions may contain three elements:
- The primary take-home message.
- Any additional findings of importance.
- Implications for future studies.

And finally... A word on abstract types and styles
Abstract types can differ according to subject discipline. You need to determine therefore which type of abstract you should include with your paper. Here are two of the most common types with examples.
Informative Abstract
The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.
Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgements about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarised. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less.

The Dissertation Abstract: 101
How to write a clear & concise abstract (with examples).
By: Madeline Fink (MSc) Reviewed By: Derek Jansen (MBA) | June 2020
So, you’ve (finally) finished your thesis or dissertation or thesis. Now it’s time to write up your abstract (sometimes also called the executive summary). If you’re here, chances are you’re not quite sure what you need to cover in this section, or how to go about writing it. Fear not – we’ll explain it all in plain language , step by step , with clear examples .
Overview: The Dissertation/Thesis Abstract
- What exactly is a dissertation (or thesis) abstract
- What’s the purpose and function of the abstract
- Why is the abstract so important
- How to write a high-quality dissertation abstract
- Example/sample of a quality abstract
- Quick tips to write a high-quality dissertation abstract
What is an abstract?
Simply put, the abstract in a dissertation or thesis is a short (but well structured) summary that outlines the most important points of your research (i.e. the key takeaways). The abstract is usually 1 paragraph or about 300-500 words long (about one page), but but this can vary between universities.
A quick note regarding terminology – strictly speaking, an abstract and an executive summary are two different things when it comes to academic publications. Typically, an abstract only states what the research will be about, but doesn’t explore the findings – whereas an executive summary covers both . However, in the context of a dissertation or thesis, the abstract usually covers both, providing a summary of the full project.
In terms of content, a good dissertation abstract usually covers the following points:
- The purpose of the research (what’s it about and why’s that important)
- The methodology (how you carried out the research)
- The key research findings (what answers you found)
- The implications of these findings (what these answers mean)
We’ll explain each of these in more detail a little later in this post. Buckle up.
![dissertation-abstract-function A good abstract should detail the purpose, the methodology, the key findings and the limitations of the research study.](https://gradcoach.com/wp-content/uploads/dissertation-abstract-function.png)
What’s the purpose of the abstract?
A dissertation abstract has two main functions:
The first purpose is to inform potential readers of the main idea of your research without them having to read your entire piece of work. Specifically, it needs to communicate what your research is about (what were you trying to find out) and what your findings were . When readers are deciding whether to read your dissertation or thesis, the abstract is the first part they’ll consider.
The second purpose of the abstract is to inform search engines and dissertation databases as they index your dissertation or thesis. The keywords and phrases in your abstract (as well as your keyword list) will often be used by these search engines to categorize your work and make it accessible to users.
Simply put, your abstract is your shopfront display window – it’s what passers-by (both human and digital) will look at before deciding to step inside.
![abstract-audience The abstract serves to inform both potential readers (people) and search engine bots of the contents of your research.](https://gradcoach.com/wp-content/uploads/abstract-audience.png)
![](http://writinghelp.online/777/templates/cheerup/res/banner1.gif)
Why’s it so important?
The short answer – because most people don’t have time to read your full dissertation or thesis! Time is money, after all…
If you think back to when you undertook your literature review , you’ll quickly realise just how important abstracts are! Researchers reviewing the literature on any given topic face a mountain of reading, so they need to optimise their approach. A good dissertation abstract gives the reader a “TLDR” version of your work – it helps them decide whether to continue to read it in its entirety. So, your abstract, as your shopfront display window, needs to “sell” your research to time-poor readers.
You might be thinking, “but I don’t plan to publish my dissertation”. Even so, you still need to provide an impactful abstract for your markers. Your ability to concisely summarise your work is one of the things they’re assessing, so it’s vital to invest time and effort into crafting an enticing shop window.
A good abstract also has an added purpose for grad students . As a freshly minted graduate, your dissertation or thesis is often your most significant professional accomplishment and highlights where your unique expertise lies. Potential employers who want to know about this expertise are likely to only read the abstract (as opposed to reading your entire document) – so it needs to be good!
Think about it this way – if your thesis or dissertation were a book, then the abstract would be the blurb on the back cover. For better or worse, readers will absolutely judge your book by its cover .
![abstract-marker Even if you have no intentions to publish your work, you still need to provide an impactful abstract for your markers.](https://gradcoach.com/wp-content/uploads/abstract-marker.png)
How to write your abstract
As we touched on earlier, your abstract should cover four important aspects of your research: the purpose , methodology , findings , and implications . Therefore, the structure of your dissertation or thesis abstract needs to reflect these four essentials, in the same order. Let’s take a closer look at each of them, step by step:
Step 1: Describe the purpose and value of your research
Here you need to concisely explain the purpose and value of your research. In other words, you need to explain what your research set out to discover and why that’s important. When stating the purpose of research, you need to clearly discuss the following:
- What were your research aims and research questions ?
- Why were these aims and questions important?
It’s essential to make this section extremely clear, concise and convincing . As the opening section, this is where you’ll “hook” your reader (marker) in and get them interested in your project. If you don’t put in the effort here, you’ll likely lose their interest.
Step 2: Briefly outline your study’s methodology
In this part of your abstract, you need to very briefly explain how you went about answering your research questions . In other words, what research design and methodology you adopted in your research. Some important questions to address here include:
- Did you take a qualitative or quantitative approach ?
- Who/what did your sample consist of?
- How did you collect your data?
- How did you analyse your data?
Simply put, this section needs to address the “ how ” of your research. It doesn’t need to be lengthy (this is just a summary, after all), but it should clearly address the four questions above.
Need a helping hand?
Step 3: Present your key findings
Next, you need to briefly highlight the key findings . Your research likely produced a wealth of data and findings, so there may be a temptation to ramble here. However, this section is just about the key findings – in other words, the answers to the original questions that you set out to address.
Again, brevity and clarity are important here. You need to concisely present the most important findings for your reader.
Step 4: Describe the implications of your research
Have you ever found yourself reading through a large report, struggling to figure out what all the findings mean in terms of the bigger picture? Well, that’s the purpose of the implications section – to highlight the “so what?” of your research.
In this part of your abstract, you should address the following questions:
- What is the impact of your research findings on the industry /field investigated? In other words, what’s the impact on the “real world”.
- What is the impact of your findings on the existing body of knowledge ? For example, do they support the existing research?
- What might your findings mean for future research conducted on your topic?
If you include these four essential ingredients in your dissertation abstract, you’ll be on headed in a good direction.
![abstract-implications The purpose of the implications section is to highlight the "so what?" of your research. In other words, to highlight its value.](https://gradcoach.com/wp-content/uploads/abstract-implications.png)
Example: Dissertation/thesis abstract
Here is an example of an abstract from a master’s thesis, with the purpose , methods , findings , and implications colour coded.
The U.S. citizenship application process is a legal and symbolic journey shaped by many cultural processes. This research project aims to bring to light the experiences of immigrants and citizenship applicants living in Dallas, Texas, to promote a better understanding of Dallas’ increasingly diverse population. Additionally, the purpose of this project is to provide insights to a specific client, the office of Dallas Welcoming Communities and Immigrant Affairs, about Dallas’ lawful permanent residents who are eligible for citizenship and their reasons for pursuing citizenship status . The data for this project was collected through observation at various citizenship workshops and community events, as well as through semi-structured interviews with 14 U.S. citizenship applicants . Reasons for applying for U.S. citizenship discussed in this project include a desire for membership in U.S. society, access to better educational and economic opportunities, improved ease of travel and the desire to vote. Barriers to the citizenship process discussed in this project include the amount of time one must dedicate to the application, lack of clear knowledge about the process and the financial cost of the application. Other themes include the effects of capital on applicant’s experience with the citizenship process, symbolic meanings of citizenship, transnationalism and ideas of deserving and undeserving surrounding the issues of residency and U.S. citizenship. These findings indicate the need for educational resources and mentorship for Dallas-area residents applying for U.S. citizenship, as well as a need for local government programs that foster a sense of community among citizenship applicants and their neighbours.
Practical tips for writing your abstract
When crafting the abstract for your dissertation or thesis, the most powerful technique you can use is to try and put yourself in the shoes of a potential reader. Assume the reader is not an expert in the field, but is interested in the research area. In other words, write for the intelligent layman, not for the seasoned topic expert.
Start by trying to answer the question “why should I read this dissertation?”
Remember the WWHS.
Make sure you include the what , why , how , and so what of your research in your abstract:
- What you studied (who and where are included in this part)
- Why the topic was important
- How you designed your study (i.e. your research methodology)
- So what were the big findings and implications of your research
Keep it simple.
Use terminology appropriate to your field of study, but don’t overload your abstract with big words and jargon that cloud the meaning and make your writing difficult to digest. A good abstract should appeal to all levels of potential readers and should be a (relatively) easy read. Remember, you need to write for the intelligent layman.
Be specific.
When writing your abstract, clearly outline your most important findings and insights and don’t worry about “giving away” too much about your research – there’s no need to withhold information. This is the one way your abstract is not like a blurb on the back of a book – the reader should be able to clearly understand the key takeaways of your thesis or dissertation after reading the abstract. Of course, if they then want more detail, they need to step into the restaurant and try out the menu.

If you are writing a scientific research paper or a book proposal, you need to know how to write an abstract, which summarizes the contents of the paper or book.
When researchers are looking for peer-reviewed papers to use in their studies, the first place they will check is the abstract to see if it applies to their work. Therefore, your abstract is one of the most important parts of your entire paper.
In this article, we’ll explain what an abstract is, what it should include, and how to write one.
An abstract is a concise summary of the details within a report. Some abstracts give more details than others, but the main things you’ll be talking about are why you conducted the research, what you did, and what the results show.
When a reader is deciding whether to read your paper completely, they will first look at the abstract. You need to be concise in your abstract and give the reader the most important information so they can determine if they want to read the whole paper.
Remember that an abstract is the last thing you’ll want to write for the research paper because it directly references parts of the report. If you haven’t written the report, you won’t know what to include in your abstract.
If you are writing a paper for a journal or an assignment, the publication or academic institution might have specific formatting rules for how long your abstract should be. However, if they don’t, most abstracts are between 150 and 300 words long.
A short word count means your writing has to be precise and without filler words or phrases. Once you’ve written a first draft, you can always use an editing tool, such as ProWritingAid, to identify areas where you can reduce words and increase readability.
If your abstract is over the word limit, and you’ve edited it but still can’t figure out how to reduce it further, your abstract might include some things that aren’t needed. Here’s a list of three elements you can remove from your abstract:
Discussion : You don’t need to go into detail about the findings of your research because your reader will find your discussion within the paper.
Definition of terms : Your readers are interested the field you are writing about, so they are likely to understand the terms you are using. If not, they can always look them up. Your readers do not expect you to give a definition of terms in your abstract.
References and citations : You can mention there have been studies that support or have inspired your research, but you do not need to give details as the reader will find them in your bibliography.
![how to write an abstract dissertation example how to write an abstract dissertation example](https://cdn.prowritingaid.com/website/2.5.62285/images/cms/blog/student.png)
Good writing = better grades
ProWritingAid will help you improve the style, strength, and clarity of all your assignments.
If you’ve never written an abstract before, and you’re wondering how to write an abstract, we’ve got some steps for you to follow. It’s best to start with planning your abstract, so we’ve outlined the details you need to include in your plan before you write.
Remember to consider your audience when you’re planning and writing your abstract. They are likely to skim read your abstract, so you want to be sure your abstract delivers all the information they’re expecting to see at key points.
1. What Should an Abstract Include?
Abstracts have a lot of information to cover in a short number of words, so it’s important to know what to include. There are three elements that need to be present in your abstract:
Your context is the background for where your research sits within your field of study. You should briefly mention any previous scientific papers or experiments that have led to your hypothesis and how research develops in those studies.
Your hypothesis is your prediction of what your study will show. As you are writing your abstract after you have conducted your research, you should still include your hypothesis in your abstract because it shows the motivation for your paper.
Throughout your abstract, you also need to include keywords and phrases that will help researchers to find your article in the databases they’re searching. Make sure the keywords are specific to your field of study and the subject you’re reporting on, otherwise your article might not reach the relevant audience.
2. Can You Use First Person in an Abstract?
You might think that first person is too informal for a research paper, but it’s not. Historically, writers of academic reports avoided writing in first person to uphold the formality standards of the time. However, first person is more accepted in research papers in modern times.
If you’re still unsure whether to write in first person for your abstract, refer to any style guide rules imposed by the journal you’re writing for or your teachers if you are writing an assignment.
3. Abstract Structure
Some scientific journals have strict rules on how to structure an abstract, so it’s best to check those first. If you don’t have any style rules to follow, try using the IMRaD structure, which stands for Introduction, Methodology, Results, and Discussion.
![how to write an abstract dissertation example how to structure an abstract](https://assets.prowritingaid.com/f/145420/750x469/9dbbec9c51/blog-content-how-to-structure-an-astract.png/m/)
Following the IMRaD structure, start with an introduction. The amount of background information you should include depends on your specific research area. Adding a broad overview gives you less room to include other details. Remember to include your hypothesis in this section.
The next part of your abstract should cover your methodology. Try to include the following details if they apply to your study:
What type of research was conducted?
How were the test subjects sampled?
What were the sample sizes?
What was done to each group?
How long was the experiment?
How was data recorded and interpreted?
Following the methodology, include a sentence or two about the results, which is where your reader will determine if your research supports or contradicts their own investigations.
The results are also where most people will want to find out what your outcomes were, even if they are just mildly interested in your research area. You should be specific about all the details but as concise as possible.
The last few sentences are your conclusion. It needs to explain how your findings affect the context and whether your hypothesis was correct. Include the primary take-home message, additional findings of importance, and perspective. Also explain whether there is scope for further research into the subject of your report.
Your conclusion should be honest and give the reader the ultimate message that your research shows. Readers trust the conclusion, so make sure you’re not fabricating the results of your research. Some readers won’t read your entire paper, but this section will tell them if it’s worth them referencing it in their own study.
4. How to Start an Abstract
The first line of your abstract should give your reader the context of your report by providing background information. You can use this sentence to imply the motivation for your research.
You don’t need to use a hook phrase or device in your first sentence to grab the reader’s attention. Your reader will look to establish relevance quickly, so readability and clarity are more important than trying to persuade the reader to read on.
5. How to Format an Abstract
Most abstracts use the same formatting rules, which help the reader identify the abstract so they know where to look for it.
Here’s a list of formatting guidelines for writing an abstract:
Stick to one paragraph
Use block formatting with no indentation at the beginning
Put your abstract straight after the title and acknowledgements pages
Use present or past tense, not future tense
There are two primary types of abstract you could write for your paper—descriptive and informative.
An informative abstract is the most common, and they follow the structure mentioned previously. They are longer than descriptive abstracts because they cover more details.
Descriptive abstracts differ from informative abstracts, as they don’t include as much discussion or detail. The word count for a descriptive abstract is between 50 and 150 words.
Here is an example of an informative abstract:
A growing trend exists for authors to employ a more informal writing style that uses “we” in academic writing to acknowledge one’s stance and engagement. However, few studies have compared the ways in which the first-person pronoun “we” is used in the abstracts and conclusions of empirical papers. To address this lacuna in the literature, this study conducted a systematic corpus analysis of the use of “we” in the abstracts and conclusions of 400 articles collected from eight leading electrical and electronic (EE) engineering journals. The abstracts and conclusions were extracted to form two subcorpora, and an integrated framework was applied to analyze and seek to explain how we-clusters and we-collocations were employed. Results revealed whether authors’ use of first-person pronouns partially depends on a journal policy. The trend of using “we” showed that a yearly increase occurred in the frequency of “we” in EE journal papers, as well as the existence of three “we-use” types in the article conclusions and abstracts: exclusive, inclusive, and ambiguous. Other possible “we-use” alternatives such as “I” and other personal pronouns were used very rarely—if at all—in either section. These findings also suggest that the present tense was used more in article abstracts, but the present perfect tense was the most preferred tense in article conclusions. Both research and pedagogical implications are proffered and critically discussed.

Here is an example of a descriptive abstract:
From the 1850s to the present, considerable criminological attention has focused on the development of theoretically-significant systems for classifying crime. This article reviews and attempts to evaluate a number of these efforts, and we conclude that further work on this basic task is needed. The latter part of the article explicates a conceptual foundation for a crime pattern classification system, and offers a preliminary taxonomy of crime.

- How to Write an Abstract for a Dissertation or Thesis
- Doing a PhD
What is a Thesis or Dissertation Abstract?
The Cambridge English Dictionary defines an abstract in academic writing as being “ a few sentences that give the main ideas in an article or a scientific paper ” and the Collins English Dictionary says “ an abstract of an article, document, or speech is a short piece of writing that gives the main points of it ”.
Whether you’re writing up your Master’s dissertation or PhD thesis, the abstract will be a key element of this document that you’ll want to make sure you give proper attention to.
What is the Purpose of an Abstract?
The aim of a thesis abstract is to give the reader a broad overview of what your research project was about and what you found that was novel, before he or she decides to read the entire thesis. The reality here though is that very few people will read the entire thesis, and not because they’re necessarily disinterested but because practically it’s too large a document for most people to have the time to read. The exception to this is your PhD examiner, however know that even they may not read the entire length of the document.
Some people may still skip to and read specific sections throughout your thesis such as the methodology, but the fact is that the abstract will be all that most read and will therefore be the section they base their opinions about your research on. In short, make sure you write a good, well-structured abstract.
How Long Should an Abstract Be?
If you’re a PhD student, having written your 100,000-word thesis, the abstract will be the 300 word summary included at the start of the thesis that succinctly explains the motivation for your study (i.e. why this research was needed), the main work you did (i.e. the focus of each chapter), what you found (the results) and concluding with how your research study contributed to new knowledge within your field.
Woodrow Wilson, the 28th President of the United States of America, once famously said:
![how to write an abstract dissertation example](https://www.biography.com/.image/t_share/MTIwNjA4NjM0MDEyOTkzMDM2/woodrow-wilson-9534272-1-402.jpg)
The point here is that it’s easier to talk open-endedly about a subject that you know a lot about than it is to condense the key points into a 10-minute speech; the same applies for an abstract. Three hundred words is not a lot of words which makes it even more difficult to condense three (or more) years of research into a coherent, interesting story.
What Makes a Good PhD Thesis Abstract?
Whilst the abstract is one of the first sections in your PhD thesis, practically it’s probably the last aspect that you’ll ending up writing before sending the document to print. The reason being that you can’t write a summary about what you did, what you found and what it means until you’ve done the work.
A good abstract is one that can clearly explain to the reader in 300 words:
- What your research field actually is,
- What the gap in knowledge was in your field,
- The overarching aim and objectives of your PhD in response to these gaps,
- What methods you employed to achieve these,
- You key results and findings,
- How your work has added to further knowledge in your field of study.
Another way to think of this structure is:
- Introduction,
- Aims and objectives,
- Discussion,
- Conclusion.
Following this ‘formulaic’ approach to writing the abstract should hopefully make it a little easier to write but you can already see here that there’s a lot of information to convey in a very limited number of words.
How Do You Write a Good PhD Thesis Abstract?
The biggest challenge you’ll have is getting all the 6 points mentioned above across in your abstract within the limit of 300 words . Your particular university may give some leeway in going a few words over this but it’s good practice to keep within this; the art of succinctly getting your information across is an important skill for a researcher to have and one that you’ll be called on to use regularly as you write papers for peer review.
Keep It Concise
Every word in the abstract is important so make sure you focus on only the key elements of your research and the main outcomes and significance of your project that you want the reader to know about. You may have come across incidental findings during your research which could be interesting to discuss but this should not happen in the abstract as you simply don’t have enough words. Furthermore, make sure everything you talk about in your thesis is actually described in the main thesis.
Make a Unique Point Each Sentence
Keep the sentences short and to the point. Each sentence should give the reader new, useful information about your research so there’s no need to write out your project title again. Give yourself one or two sentences to introduce your subject area and set the context for your project. Then another sentence or two to explain the gap in the knowledge; there’s no need or expectation for you to include references in the abstract.
Explain Your Research
Some people prefer to write their overarching aim whilst others set out their research questions as they correspond to the structure of their thesis chapters; the approach you use is up to you, as long as the reader can understand what your dissertation or thesis had set out to achieve. Knowing this will help the reader better understand if your results help to answer the research questions or if further work is needed.
Keep It Factual
Keep the content of the abstract factual; that is to say that you should avoid bringing too much or any opinion into it, which inevitably can make the writing seem vague in the points you’re trying to get across and even lacking in structure.
Write, Edit and Then Rewrite
Spend suitable time editing your text, and if necessary, completely re-writing it. Show the abstract to others and ask them to explain what they understand about your research – are they able to explain back to you each of the 6 structure points, including why your project was needed, the research questions and results, and the impact it had on your research field? It’s important that you’re able to convey what new knowledge you contributed to your field but be mindful when writing your abstract that you don’t inadvertently overstate the conclusions, impact and significance of your work.
Thesis and Dissertation Abstract Examples
Perhaps the best way to understand how to write a thesis abstract is to look at examples of what makes a good and bad abstract.
Example of A Bad Abstract
Let’s start with an example of a bad thesis abstract:
In this project on “The Analysis of the Structural Integrity of 3D Printed Polymers for use in Aircraft”, my research looked at how 3D printing of materials can help the aviation industry in the manufacture of planes. Plane parts can be made at a lower cost using 3D printing and made lighter than traditional components. This project investigated the structural integrity of EBM manufactured components, which could revolutionise the aviation industry.
What Makes This a Bad Abstract
Hopefully you’ll have spotted some of the reasons this would be considered a poor abstract, not least because the author used up valuable words by repeating the lengthy title of the project in the abstract.
Working through our checklist of the 6 key points you want to convey to the reader:
- There has been an attempt to introduce the research area , albeit half-way through the abstract but it’s not clear if this is a materials science project about 3D printing or is it about aircraft design.
- There’s no explanation about where the gap in the knowledge is that this project attempted to address.
- We can see that this project was focussed on the topic of structural integrity of materials in aircraft but the actual research aims or objectives haven’t been defined.
- There’s no mention at all of what the author actually did to investigate structural integrity. For example was this an experimental study involving real aircraft, or something in the lab, computer simulations etc.
- The author also doesn’t tell us a single result of his research, let alone the key findings !
- There’s a bold claim in the last sentence of the abstract that this project could revolutionise the aviation industry, and this may well be the case, but based on the abstract alone there is no evidence to support this as it’s not even clear what the author did .
This is an extreme example but is a good way to illustrate just how unhelpful a poorly written abstract can be. At only 71 words long, it definitely hasn’t maximised the amount of information that could be presented and the what they have presented has lacked clarity and structure.
A final point to note is the use of the EBM acronym, which stands for Electron Beam Melting in the context of 3D printing; this is a niche acronym for the author to assume that the reader would know the meaning of. It’s best to avoid acronyms in your abstract all together even if it’s something that you might expect most people to know about, unless you specifically define the meaning first.
Example of A Good Abstract
Having seen an example of a bad thesis abstract, now lets look at an example of a good PhD thesis abstract written about the same (fictional) project:
Additive manufacturing (AM) of titanium alloys has the potential to enable cheaper and lighter components to be produced with customised designs for use in aircraft engines. Whilst the proof-of-concept of these have been promising, the structural integrity of AM engine parts in response to full thrust and temperature variations is not clear.
The primary aim of this project was to determine the fracture modes and mechanisms of AM components designed for use in Boeing 747 engines. To achieve this an explicit finite element (FE) model was developed to simulate the environment and parameters that the engine is exposed to during flight. The FE model was validated using experimental data replicating the environmental parameters in a laboratory setting using ten AM engine components provided by the industry sponsor. The validated FE model was then used to investigate the extent of crack initiation and propagation as the environment parameters were adjusted.
This project was the first to investigate fracture patterns in AM titanium components used in aircraft engines; the key finding was that the presence of cavities within the structures due to errors in the printing process, significantly increased the risk of fracture. Secondly, the simulations showed that cracks formed within AM parts were more likely to worsen and lead to component failure at subzero temperatures when compared to conventionally manufactured parts. This has demonstrated an important safety concern which needs to be addressed before AM parts can be used in commercial aircraft.
What Makes This a Good Abstract
Having read this ‘good abstract’ you should have a much better understand about what the subject area is about, where the gap in the knowledge was, the aim of the project, the methods that were used, key results and finally the significance of these results. To break these points down further, from this good abstract we now know that:
- The research area is around additive manufacturing (i.e. 3D printing) of materials for use in aircraft.
- The gap in knowledge was how these materials will behave structural when used in aircraft engines.
- The aim was specifically to investigate how the components can fracture.
- The methods used to investigate this were a combination of computational and lab based experimental modelling.
- The key findings were the increased risk of fracture of these components due to the way they are manufactured.
- The significance of these findings were that it showed a potential risk of component failure that could comprise the safety of passengers and crew on the aircraft.
The abstract text has a much clearer flow through these different points in how it’s written and has made much better use of the available word count. Acronyms have even been used twice in this good abstract but they were clearly defined the first time they were introduced in the text so that there was no confusion about their meaning.
The abstract you write for your dissertation or thesis should succinctly explain to the reader why the work of your research was needed, what you did, what you found and what it means. Most people that come across your thesis, including any future employers, are likely to read only your abstract. Even just for this reason alone, it’s so important that you write the best abstract you can; this will not only convey your research effectively but also put you in the best light possible as a researcher.
