The introduction needs to set the scene for the later work and give a broad idea of the arguments and/or research that preceded yours.
It should give some idea of why you chose to study this area, giving a flavour of the literature, and what you hoped to find out.
This is especially important for the introduction because it needs to hold your reader’s attention and lead them into your research.
The best way to ensure that you can do this is to give yourself enough time to write a really good introduction, including several redrafts.
Secondly, your dissertation needs an expert to mark it.
The proposal offers the department a ‘snapshot’ of your proposed topic and allows the department to assign a suitable tutor to you who has the knowledge to help and advise you, as well as the expertise to mark the finished piece of work.Unlike your research proposal, however, you have now completed the work.This means that your introduction can be much clearer about what exactly you chose to investigate and the precise scope of your work.You have to write a proposal for your department to agree to the topic of the dissertation, although some fine-tuning of the topic is usually available during the dissertation writing process.There are a number of reasons for the submission of dissertation proposals.A dissertation proposal is a brief overview of the aims and significance of your dissertation research.The aim of the proposal is to demonstrate to your dissertation committee that your dissertation will represent an original and beneficial contribution to your field.You should write a draft of your introduction very early on, perhaps as early as when you submit your research proposal, to set out a broad outline of your ideas, why you want to study this area, and what you hope to explore and/or establish.You can, and should, update your introduction several times as your ideas develop.Don’t include too many citations in your introduction: this is your summary of why you want to study this area, and what questions you hope to address.Any citations are only to set the context, and you should leave the bulk of the literature for a later section.
