To write the first chapter of a bachelor's or master's thesis, define what it needs to explain and the scope it should cover. Break it down into subchapters and assign verified sources to each. Then work on one issue at a time: explain the concepts, compare the findings of different authors, and show how they will be used in your thesis.
You do not need to begin with a perfect opening sentence. It is easier to write the chapter introduction once you know what the chapter will actually contain.
You open the document, type 'Chapter 1' and stop in front of a blank page. The folder contains books, articles and notes, but they do not yet form a text. In this situation, dividing the work into stages helps: first, you decide what you want to explain, then you select the material, and only then do you build the sentences.
The following guide mainly concerns theses where the theoretical part prepares for further analysis or research. If you are still choosing a topic, start with the thesis plan and preparation for the meeting with your supervisor. Here, we move from an approved direction of work to the first draft of the chapter.
What should a theoretical chapter contain?
The first chapter of a bachelor's thesis, if it serves as the theoretical part, explains the meaning in which you use concepts, which approaches help understand the problem, and what follows from previous studies. Its scope should correspond to the aim of the thesis. The reader should receive the foundations needed to understand the subsequent parts of the document.
Concepts
Explain the terms that will recur in the thesis. If authors understand them differently, show the difference and justify the meaning you have adopted.
Concepts and findings
Select theories and results of previous research that are relevant to the problem. Compare them using a common criterion.
Connection to the thesis
Indicate how the discussed material helps plan the analysis, justify the questions, or interpret later results.
The first chapter is not always a theoretical chapter. In a project-based thesis, it may present the problem to be solved and the project requirements, while in a monographic thesis, it may introduce the issue being analysed. Adapt the structure to the type of thesis, its aim, and the requirements of your field of study. It is important that this part prepares the reader for further analysis and clearly connects with the subsequent chapters.
The theoretical chapter of a master's thesis may require a deeper comparison of positions than a bachelor's thesis, but the difference does not come down to adding pages. Agree on the level of detail and the independence of the analysis with your supervisor.
How to start the first chapter of a bachelor's or master's thesis?
Check the requirements and agreements
Open the faculty guidelines and notes from the seminar. Note the expected scope, citation style, and deadline for submitting the fragment. Clarify whether your supervisor wants the whole chapter immediately or first one subchapter for evaluation.
Define the aim and scope of the chapter
Complete the working sentence: 'After reading this part, the reader should understand…'. If you list several unrelated topics, narrow the scope. For a thesis on academic stress, you need concepts and findings related to this phenomenon, not a complete psychology textbook.
Turn headings into questions
Under the heading 'Sources of academic stress', write, for example: 'What study-related burdens are described in selected research?'. The question helps you discard materials that fit the word 'stress' but do not answer the question discussed in this part.
Link questions with sources
For each issue, note the publications you have read and the passages you will use. If you cannot support a subsection with the available material, extend your search or discuss changing the plan.
Write a draft of one fragment
Choose the issue for which you have the best prepared notes. Write a few connected paragraphs and add references immediately. At the end, check the sense, sources, and repetitions. Only then refine the opening of the whole chapter.
Instead of “I will write the theory section today”, choose “I will list the questions for subsection 1.1 and match them with material I have read”. That list will show whether you can start writing or still need a particular source.
First chapter of a bachelor's thesis – sample plan
Assume a working topic: 'Academic stress and coping methods among students of a selected field of study'. The following structure is a didactic proposal to be adapted, not a description of a conducted study.
- 1.1. The concept of stress and the specificity of academic stress. Organise the meanings of the terms and explain how you will use them.
- 1.2. Study-related burdens in previous research. Compare the identified areas, taking into account the groups of respondents and the method of data collection.
- 1.3. Approaches to describing coping with stress. Explain selected classifications and their relevance to the topic.
- 1.4. Implications of the review for your own research. Indicate which distinctions you will use and which questions require further exploration.
In subsection 1.2, you do not need to describe all difficulties of student life. Choose those that fit the adopted understanding of academic stress. Conversely, describing the construction of your own questionnaire belongs to methodology; in the theory section, you justify the concepts on which you will base the project.
Check the boundaries between sections. If the definition of coping appears in 1.1 and again in 1.3, choose one main place for it. Elsewhere, a reference back will suffice. For a broader check of the structure, see the guide explaining how to organise the structure of a thesis.
How to organise sources before writing?
A folder full of PDFs does not yet say what will be in the chapter. Prepare notes where each one answers a specific question. The cards below show what information to record for materials for three subsections. You can copy their layout into a text editor or spreadsheet and add further sources.
Material cards for subsections
1.1. Concepts
- Question: How was the main concept defined?
- Source and location: Author, year, title, page or section
- Author's finding: Personal note from the read fragment
- Usage: Working definition or comparison of approaches
1.2. Research
- Question: Who was studied and what was established?
- Source and location: Full description of the publication, table or page
- Author's finding: Result with scope and limitations
- Usage: Comparison of studies with a similar question
1.3. Coping
- Question: What criteria were used to distinguish the approaches?
- Source and location: Description of the source and location of the classification
- Author's finding: Criterion of division adopted by the author
- Usage: Justification of concepts used in the thesis
The cards contain instructions for completing them, not ready-made research findings. In your own notes, distinguish direct quotations from paraphrases and your comments. Record the page number immediately if the publication has one. Searching later for a single sentence in a book hundreds of pages long interrupts the writing unnecessarily.
For research results, also note the group, place, period and method. Two similarly sounding conclusions may concern completely different situations. If material is missing, return to the guide on how to find literature for a thesis. Do not supplement the bibliography with an item known only from an AI generator response; first check its existence and content.
Check what is missing to write the chapter
- Are you missing publications for the topics in your plan? You can commission the service “Literature search and selection for your thesis”. The scope includes preparing and providing the necessary literature and bibliography for the entire thesis or a specified chapter, along with information on the relevance of the publications and how to access them.
- Do you have sources, but they do not form a coherent text? Developing the theoretical chapter involves explaining concepts, comparing viewpoints, and linking the content with actual publications. You will find details of this scope below.
How to write the first paragraph of a theoretical chapter?
First, define the main idea of the paragraph: what do you want to explain in it? A helpful working scheme is main idea → material from sources → comparison or explanation → relevance to the topic. Not every paragraph needs exactly four sentences. What matters is that it has a clear direction.
Beata Stępień explains that a literature review helps to organise what is already known about a given issue and to identify questions that remain unresolved. In your chapter, therefore, arrange publications around a common question: show where authors agree, how their approaches differ, and what conclusions follow from the comparison. This way, the paragraph creates a coherent argument rather than being a list of summaries of successive texts.
Methodological basis: B. Stępień, “Systematyczny przegląd literatury – cel, rodzaje, procedura”, in: B. Stępień (ed.), Systematyczny przegląd literatury w naukach ekonomicznych. Metodyka, przykłady, Wydawnictwo Uniwersytetu Ekonomicznego w Poznaniu, 2023, p. 11.
Assume, solely for the purpose of this exercise, that Source A describes assessment situations, while Source B describes the organisation of study. The letters do not denote actual publications. The example illustrates the structure of the statement; in your thesis, you must use verified findings and correct references.
Fragment requiring improvement
“Source A describes exams. Source B describes the organisation of study. Students have many obligations. Stress is an important problem.”
The sentences stand side by side but do not explain what follows from the comparison. The last statement is general, and its connection to the cited materials remains unclear.
Version with a clear comparison
“When organising academic workload, one can distinguish between assessment situations and the organisation of daily study. The first area is described by Source A, the second by Source B. These approaches concern different aspects of studying, so they should not be treated as descriptions of the same type of situation. In the following part of the thesis, both areas will be discussed separately.”
The change lies in naming the criterion of comparison and showing the consequences for the structure of the text. This is still an exercise, not a paragraph ready to be used as knowledge about stress. In a real chapter, every finding attributed to an author must match the source.
When editing, remove phrases that do not add information, such as “since time immemorial” or “in today’s times, the topic is very important”. It is better to point out the problem immediately. If you are unsure where to place a reference, check the rules for checking bibliography and footnotes.
How to conclude a subchapter and link theory with research?
When writing the first chapter of a bachelor's or master's thesis, at the end of the subchapter, state which distinction or finding will be needed later. Do not introduce a new, extensive topic at that point. The summary should result from the discussion conducted.
For a sample plan, a neutral transition might sound like this: “After organising the concept of academic stress, the next step is to discuss the workload associated with studying, as described in selected studies”. Such a sentence foreshadows the topic of the next part without prejudging its results.
When finishing the theory, return to the questions of your thesis. Indicate which concepts and classifications you will use. Do not automatically declare a “research gap” just because no publications were found about one specific university. The justification of the project should correspond to what actually follows from the reviewed literature.
How many pages and sources should the first chapter of a bachelor's thesis have?
There is no single number of pages suitable for every bachelor's and master's thesis. The length of the chapter depends on the problem discussed, the structure of the entire thesis, and the requirements of the field of study. Check the guidelines of your faculty and the arrangements with your supervisor.
If the supervisor has not specified expectations, present the chapter plan and ask about the scope. Evaluate the material by asking: am I explaining the necessary concepts, am I discussing important viewpoints, and am I avoiding repetitions? Ten extra pages of generalities will not solve the lack of an important concept.
The number of sources also does not replace their quality and relevance. One publication may discuss a narrow problem in detail, but basing the entire theoretical part on one author requires particular caution. The selection should allow for a thorough treatment of the issue and meet the requirements of the seminar.
Most common errors in the first chapter and ways to correct them
- A series of definitions without commentary. Point out the differences between approaches and explain which meaning you adopt and why.
- Summarising each book separately. Reorganise the material around issues so that viewpoints on the same question are placed close to each other.
- Too broad historical background. Check which information is needed to understand the problem. Shorten or remove the rest.
- Repetitions between subchapters. Assign a main location to each concept and then refer back to it.
- The source does not confirm the sentence. Open the publication and check the full context. Correct the claim or find the appropriate basis.
- The paraphrase is too close to the original. Return to the meaning of the fragment, develop your own discussion, and keep the reference. Simply swapping words is not enough.
- Theory detached from the objective. For each subsection, note how it will be used later. A lack of answer is a signal to change the scope.
First fix the structure and meaning, then the sentence style. If you rearrange half the fragments, earlier smoothing of each transition may need to be repeated.

Message template for the supervisor
Dear Sir/Madam,
I am sending the first draft of the theoretical chapter for my thesis entitled “[title]”. Please review the scope, the order of subsections and the use of the literature. My main concern relates to section [number and topic]: [specific question]. I would be grateful if you could indicate what to correct before starting the next stage.
Complete the placeholders and adapt the form of address to the recipient. If you are sending only part of the chapter, identify it in the message and explain what is still missing.
Most common questions about the first chapter of the thesis
Usually, the introduction and the first substantive chapter serve different functions. The introduction presents the topic, objective, scope, and structure of the work. The theoretical chapter develops the concepts, theories, and literature findings necessary for further analysis. However, some programmes use a different structure or number the introduction as a chapter. Check your faculty guidelines and the agreed plan. Yes, if the topic and the adopted structure of the work justify it. For example, two chapters might discuss separate areas whose relationship you analyse later. Each chapter should have a clear function and lead towards the objective of the work. Do not split the theory solely to increase the number of chapters, and do not repeat the same definitions. Agree on the structure with your supervisor. There is no universal rule for this. You can start with a brief presentation of the problem and an explanation of the chapter's purpose, then clarify key concepts. Select definitions according to the objective of the work and compare their significance for the issue being analysed. The order depends on the discipline, the nature of the work, and the supervisor's guidelines. It is not the number of paragraphs that decides, but the origin of the information. Others' findings, definitions, data, arguments, and paraphrases require source attribution according to the applied style. Your own introduction to the chapter structure may not require a citation. However, the reader must know which sentences are based on a specific publication. One footnote at the end of a long paragraph may be insufficient when discussing multiple authors. Check if you are only summarising successive publications. Choose a common issue and compare how authors define it, what material they work with, and what conclusions they reach. Explain similarities, differences, and the limitations of the comparison, then show their significance for your topic. Do not add evaluations without justification in the sources. For a general comment, ask the supervisor to point to one section where you can practise the change. Check the current university rules and agreements with your supervisor. Ask about the permissible scope, how to disclose the use of the tool, and data protection. Do not assume that permission for language correction means consent to generate a chapter.Is the first chapter of a thesis the introduction?
Can the theoretical part have more than one chapter?
