The problem with providing a simple answer that will apply universally to every scholarly thesis and dissertation is that each research project is unique and will therefore present its own specific requirements.
Several factors may play a role in determining the length of the final document.
The physical context of the research should also be clarified by explaining where your research takes place, who is involved and why the location you have chosen is appropriate.
• Establish a conceptual framework for the thesis or dissertation.
In fact, the introductions to scholarly theses and dissertations of all kinds tend to have very similar primary functions, so I have listed a number of these below.
Do be aware, however, that these points are particularly relevant to a thesis or dissertation that makes an original contribution to knowledge.Some of them may not be necessary or useful for your thesis or dissertation, they might be presented in a variety of different orders, and disciplines and departments will vary in the terminology used to describe them, so it is essential while using this list to prioritise any instructions you obtain from your own educational institution and mentors.Generally speaking, however, the introduction to a scholarly thesis or dissertation should • Identify clearly, accurately and with as much precision as possible the topic, problem or phenomenon on which your research focuses.Department and university guidelines may list or describe the basic contents expected in the introduction; your mentors may have very specific ideas about what must be communicated to clarify your research; and those successful theses and dissertations will reveal what other students chose to write about in their introductions.Although precisely what a scholarly introduction should contain varies, so that a master’s dissertation in the social sciences will provide entirely different kinds of information than a doctoral thesis in art history will, the basic structures and purposes of both are usually not so very different at all.Even more important, however, will be the content you are required to include in your introduction.Here, too, those guidelines, mentors and successful theses and dissertations will prove invaluable.• Introduce, usually briefly, the methods and approaches you have adopted or devised to investigate the topic or problem.Your methodology need not be new, but it should be the most effective possible, and for postgraduate research it is usually best if its application to the problem is in some way innovative, so do emphasise those aspects. The intellectual and theoretical context of your research might be covered in your discussion of the background or scholarship, but it can be described separately.How Long Should a Dissertation or Thesis Introduction Be?How long should the introduction to your thesis or dissertation be?
