Dissertation Introduction And Background Of A Project

How to Write your Introduction, Abstract and Summary

Posted on Updated on

These are the most important components of your thesis or report.  Put your biggest effort into getting them perfect.  Most professors read the Abstract, Introduction and Conclusions chapters of a thesis first, then they dive into the main body text afterwards.  This means that you have to be particularly careful in wording these sections, since there is some content overlap.  If you just copy and paste text between them, people will notice and it won’t leave them with a very favourable impression.  Many people read technical reports in the same order – in fact, some people actually never read anything but the Abstract, Introduction and Conclusions!  

There are some fairly specific rules related to these thesis (or technical report) components that you must know about. There are also some common sense guidelines that are useful to know – the main one being the advice above not to cut and paste text.  Another is that you write these three thesis/report components last.  Yes, that’s right – you write the Introduction and Abstract last – after you have written the entire report or thesis contents.  (You can be stubborn and write them first if you like; just be prepared to do them twice, because you’ll find they have to be completely rewritten in the end anyway.) 

The fact that these are written last generally means they are often the most poorly written – since most people naturally start to burn out as they approach the end of such a large writing project.  However, keep in mind that these are the sections that will get the most attention and scrutiny – so you absolutely have to make them your best content in the document.  Here’s a general overview of how to write these important sections, presented in the typical order in which they are written.

What goes in your ‘Introduction’?

A good technical report/thesis Introduction does four things:

1.       It introduces the problem and motivation for the study.

  • Tell the reader what the topic of the report is.
  • Explain why this topic is important or relevant.

2.       It provides a brief summary of previous engineering and/or scientific work on the topic.

  • Here you present an overview what is known about the problem.  You would typically cite earlier studies conducted on the same topic and/or at this same site, and in doing so, you should reveal the yawning void in the knowledge that your brilliant research will fill.
  • If you are writing a thesis, you’re going to need a full-blown literature review with very specific details of all of the scientific or engineering work done on the topic to date.  This literature review is usually contained in its own chapter, particularly for PhD theses.  In the introduction, just present a brief overview, sufficient to establish the need for your research.

3.       It outlines the purpose and specific objectives of the project.

  • These are linked to solving the problem or filling the knowledge gap identified above.
  • Often, the specific objectives are listed in point form. Sometimes a numbered list is used.

4.       It provides a ‘road map’ for the rest of the report.

  • This is so that the reader knows what’s coming and sees the logic of your organization.
  • Describe (in approximately one sentence each) the contents of each of the report/thesis chapters.

What doesn’t go in your Introduction?

  • Never put any results or decisions in the Introduction.  Just because you are writing it last doesn’t mean you should give away the story. After all – it’s called the “Introduction” for a reason. 😉

What goes in your ‘Conclusions’ chapter?

The purpose of this chapter is to provide a summary of the whole thesis or report.  In this context, it is similar to the Abstract, except that the Abstract puts roughly equal weight on all thesis/report chapters, whereas the Conclusions chapter focuses primarily on the findings, conclusions and/or recommendations of the project.

There are a couple of rules – one rigid, one common sense, for this chapter:

  • All material presented in this chapter must have appeared already in the report; no new material can be introduced in this chapter. (rigid rule of technical writing)
  • Usually, you would not present any new figures or tables in this chapter. (rule of thumb)

Generally, for most technical reports and Masters theses, the Conclusions chapter would be~3 to 5 pages long (double spaced).  It would generally be longer in a large PhD thesis. Typically you would have a paragraph or two for each chapter or major subsection.  Aim to include the following (typical) content.

  • Re-introduce the project and the need for the work – though more briefly than in the intro;
  • Re-iterate the purpose and specific objectives of your project.
  • Re-cap the approach taken – similar to the road map in the intro; however, in this case, you are re-capping the data, methodology and results as you go.
  • Summarize the major findings and recommendations of your work.
  • Make recommendations for future research.

What goes in your ‘Abstract’?

(generally called the Executive Summary in technical reports)

In short, everything goes in the Abstract.  Its purpose is to provide a summary of the whole report or thesis.  In this context, it is similar to the Conclusions chapter, except that the Abstract gives the individual chapters more even weighting and is typically much shorter overall.

There are also a few rules for the Abstract.

  • All material presented in the Abstract must appear in the report body as well; no new material is allowed. (rigid rule of technical writing)
  • Do not present any figures or tables in the Abstract. (rigid rule of technical writing)
  • Do not cite references the Executive Summary. (if you need to, then you are getting too detailed)

Generally, the Abstract would fit on one page (single spaced) with approximately one paragraph for each chapter.  Here is the typical content.

  • Present the project topic and the need for the work.
  • State the specific objectives of the project.
  • Re-cap the approach taken, major decisions and results.
  • Summarize the major conclusions and recommendations of your work.

It’s important to keep in mind that some universities put very stringent length restriction on theses Abstracts, which makes them even harder to write.  If you are faced with this challenge, don’t deal with it by leaving out your results and conclusions.  Everything above must still be covered; but you will have to be extremely brief and articulate.  Generally, you will not be able to get into any details on the methodologies and decisions.

In my next post, I will give some advice on that most dreaded of all chapters – the Literature Review.

Contents

This section describes the main elements of a written thesis at the bachelor’s and master’s levels. Although the specific structure described here is most relevant for empirical theses, much of the advice is also relevant for theoretical work. Please note that the formal requirements vary between different disciplines, and make sure to confer the guidelines that apply in your field.

For the contents in the various sections you may also confer Organising your writing.

Abstract and foreword

Most readers will turn first to the abstract. Use it as an opportunity to spur the reader’s interest. The abstract should summarise the main contents of your thesis, especially the thesis statement,  but does not need to cover every aspect of the main text. The main objective is to give the reader a good idea of what the thesis is about.

In general the abstract should be the last thing that you write, when you know what you have actually written. It is nevertheless a good idea to work on a draft continuously. Writing a good abstract is difficult, since it should only include the most important points of your work. But this is also why working on your abstract can be useful – it forces you to identify exactly what it is you are writing about.

There are usually no formal requirements for forewords, but it is common practice to thank your supervisors, informants, and others who have helped and supported you. If you have received any grants or research residencies, you should also acknowledge these.

Note: Shorter assignments do not require abstracts and forewords.

1. Introduction

Your introduction has two main purposes: 1) to give an overview of the main points of your thesis; and 2) awaken the reader’s interest. It’s not a bad idea to go through the introduction one last time when the writing is done, to ensure that it connects well with your conclusion.

Tip: For a nice, stylistic twist you can reuse a theme from the introduction in your conclusion. For example, you might present a particular scenario in one way in your introduction, and then return to it in your conclusion from a different – richer or contrasting – perspective.

Your introduction should include:

  • The background for your choice of theme 
  • A discussion of your research question or thesis statement 
  • A schematic outline of the remainder of your thesis 

The sections below discuss each of these elements in turn.

1.1 Background

The background sets the general tone for your thesis. It should make a good impression and convince the reader why the theme is important and your approach relevant. Even so, it should be no longer than necessary.

What is considered a relevant background depends on your field and its traditions. Background information might be historical in nature, or it might refer to previous research or practical considerations. You can also focus on a specific text, thinker or problem.

Academic writing often means having a discussion with yourself (or some imagined opponent). To open your discussion, there are several options available. You may, for example:

  • refer to a contemporary event  
  • outline a specific problem; a case study or an example
  • review the relevant research/literature to demonstrate the need for this particular type of research 

If it is common in your discipline to reflect upon your experiences as a practitioner, this is the place to present them. In the remainder of your thesis, this kind of information should be avoided, particularly if it has not been collected systematically.

Tip: Do not spend too much time on your background and opening remarks before you have gotten started with the main text.

Exercise

Write three different opening paragraphs for your thesis using different literary devices 

For example:
a) “set the scene” with a (short) narrative 
b) adopt a historical approach to the phenomenon you intend to discuss
c) take an example from the media to give your topic current relevance.

Observe to what extent these different openings inspire you, and choose the approach most appropriate to your topic. For example, do you want to spur emotions, or remain as neutral as possible? How important is the historical background? The exercise can be done in small groups or pairs. Discuss what makes an opening paragraph successful (or not). How does your opening paragraph shed light on what is to follow? What will the reader’s expectations be?

1.2 Defining the scope of your thesis

One of the first tasks of a researcher is defining the scope of a study, i.e., its area (theme, field) and the amount of information to be included. Narrowing the scope of your thesis can be time-consuming. Paradoxically, the more you limit the scope, the more interesting it becomes. This is because a narrower scope lets you clarify the problem and study it at greater depth, whereas very broad research questions only allow a superficial treatment.

The research question can be formulated as one main question with (a few) more specific sub-questions or in the form of a hypothesis that will be tested.

Your research question will be your guide as your writing proceeds. If you are working independently, you are also free to modify it as you go along. 

How do you know that you have drafted a research question? Most importantly, a research question is something that can be answered. If not, you have probably come up with a theme or field, not a question.

Some tips:

  • Use interrogative words: how, why, which (factors/situations) etc.
  • Some questions are closed and only invoke concrete/limited answers. Others will open up for discussions and different interpretations.
    Asking “What …?” is a more closed question than asking “How?” or “In what way?”
    Asking “Why” means you are investigating what causes of a phenomenon. Studying causality is methodologically demanding.
  • Feel free to pose partially open questions that allow discussions of the overall theme, e.g., “In what way …?”; “How can we understand [a particular phenomenon]?”
  • Try to condense your research question into one general question – and perhaps a few more specific sub-questions (two or three will usually suffice).

1.3 Outline

The outline gives an overview of the main points of your thesis. It clarifies the structure of your thesis and helps you find the correct focus for your work. The outline can also be used in supervision sessions, especially in the beginning. You might find that you need to restructure your thesis. Working on your outline can then be a good way of making sense of the necessary changes. A good outline shows how the different parts relate to each other, and is a useful guide for the reader.

It often makes sense to put the outline at the end of the introduction, but this rule is not set in stone. Use discretion: What is most helpful for the reader? The information should come at the right point – not too early and not too late.

2. Theory section 

The theory used in an empirical study is meant to shed light on the data in a scholarly or scientific manner. It should give insights not achievable by ordinary, everyday reflections. The main purpose of using theory is to analyse and interpret your data. Therefore, you should not present theoretical perspectives that are not being put to use. Doing so will create false expectations, and suggests that your work is incomplete.

Not all theses have a separate theory section. In the IMRaD format the theory section is included in the introduction, and the second chapter covers the methods used.

What kind of theory should you choose? Since the theory is the foundation for your data analysis it can be useful to select a theory that lets you distinguish between, and categorise different phenomena. Other theories let you develop the various nuances of a phenomenon. In other words, you have a choice of either reducing the complexity of your data or expanding upon something that initially looks simple.

How much time and space should you devote to the theory chapter? This is a difficult question. Some theses dwell too long on theory and never get to the main point: the analysis and discussion. But it is also important to have read enough theory to know what to look for when collecting data. The nature of your research should decide: Some studies do not require much theory, but put more emphasis on the method, while other studies need a rich theory section to enable an interesting discussion.

3. Method section  

In a scholarly research article, the section dealing with method is very important. The same applies to an empirical thesis. For students, this can be a difficult section to write, especially since its purpose may not always be clear.

The method chapter should not iterate the contents of methodology handbooks. For example, if you have carried out interviews, you do not need to list all the different types of research interview. You also do not need to describe the differences between quantitative and qualitative methods, or list all different kinds of validity and reliability.

What you must do is to show how your choice of design and research method is suited to answering your research question(s). Demonstrate that you have given due consideration to the validity and reliability of your chosen method. By “showing” instead of “telling”, you demonstrate that you have understood the practical meaning of these concepts. This way, the method section is not only able to tie the different parts of your thesis together, it also becomes interesting to read!  

  • Show the reader what you have done in your study, and explain why. How did you collect the data? Which options became available through your chosen approach?
  • What were your working conditions? What considerations did you have to balance? 
  • Tell the reader what you did to increase the validity of your research. E.g., what can you say about the reliability in data collection? How do you know that you have actually investigated what you intended to investigate? What conclusions can be drawn on this basis? Which conclusions are certain and which are more tentative? Can your results be applied in other areas? Can you generalise? If so, why? If not, why not?
  • You should aim to describe weaknesses as well as strengths. An excellent thesis distinguishes itself by defending – and at the same time criticising – the choices made. 

4. Analysis

Your analysis, along with your discussion, will form the high light of your thesis. In the IMRaD format, this section is titled “Results”. This is where you report your findings and present them in a systematic manner. The expectations of the reader have been built up through the other chapters, make sure you fulfill these expectations.

To analyse means to distinguish between different types of phenomena – similar from different. Importantly, by distinguishing between different phenomena, your theory is put to work. Precisely how your analysis should appear, however, is a methodological question. Finding out how best to organise and present your findings may take some time. A good place to look for examples and inspiration is repositories for master’s theses. 

If you are analysing human actions, you may want to engage the reader’s emotions. In this case it will be important to choose analytical categories that correlate to your chosen theory. Engaging emotions is not the main point, but a way to elucidate the phenomenon so that the reader understands it in a new and better way.

Note: Not all theses include a separate chapter for analysis. 

5. Discussion

In many thesis the discussion is the most important section. Make sure that you allocate enough time and space for a good discussion. This is your opportunity to show that you have understood the significance of your findings and that you are capable of applying theory in an independent manner. 

The discussion will consist of argumentation. In other words, you investigate a phenomenon from several different perspectives. To discuss means to question your findings, and to consider different interpretations. Here are a few examples of formulations that signal argumentation:

  • On the one hand … and on the other
  • But is it really true that…
  • … on can it also be supposed…?
  • … another possible explanation may be …

6. Conclusion – or summing up?

The final section of your thesis may take one of several different forms. Some theses need a conclusion, while for others a summing up will be appropriate. The decisive factor will be the nature of your thesis statement and research question.

Open research questions cannot always be answered, but if a definite answer is possible, you must provide a conclusion. The conclusion should answer your research question(s). Remember that a negative conclusion is also valid.

A summing up should repeat the most important issues raised in your thesis (particularly in the discussion), although preferably stated in a (slightly) different way. For example, you could frame the issues within a wider context.

Placing your thesis in perspective

In the final section you should place your work in a wider, academic perspective and determine any unresolved questions. During the work, you may have encountered new research questions and interesting literature which could have been followed up. At this point, you may point out these possible developments, while making it clear for the reader that they were beyond the framework of your current project. 

  • Briefly discuss your results through a different perspective. This will allow you to see aspects that were not apparent to you at the project preparation stage
  • Highlight alternative research questions that you have found in the source materials used in the project
  • Show how others have placed the subject area in a wider context
  • If others have drawn different conclusions from yours, this will provide you with ideas of new ways to view the research question
  • Describe any unanswered aspects of your project
  • Specify potential follow up and new projects

A thesis should “bite itself in the tail”

There should be a strong connection between your conclusion and your introduction. All the themes and issues that you raised in your introduction must be referred to again in one way or another. If you find out at this stage that your thesis has not tackled an issue that you raised in the introduction, you should go back to the introduction and delete the reference to that issue. An elegant way to structure the text is to use the same textual figure or case in the beginning as well as in the end. When the figure returns in the final section, it will have taken on a new and richer meaning through the insights you have encountered, created in the process of writing.
