Before you begin to think about possible Dissertation Topics to investigate, make sure you are clear in your own mind about what a Dissertation is. You will be familiar with the principles of essay writing, the most common form of academic writing, but it is worth reviewing briefly what an essay is really designed to do, and looking at how a dissertation may echo but also differ from a standard university Projects
Different subject disciplines may emphasise different features, but, broadly speaking, an essay is a continuous piece of writing, arranged in clearly demarcated paragraphs, in which an argument (a clear line of thought) is developed, in response to a central question or proposition (thesis). The line of argument is supported by evidence you have acquired through research, which you are required to analyse, and which supports or contradicts the various perspectives explored in the course of that argument.
The essay then reaches a conclusion in the final section, which pulls together the threads of your argument, supporting, qualifying or rejecting the original Sample Dissertations
It is worth bearing in mind that an academic essay is not a piece of writing designed to reproduce information available elsewhere, but something new and expressive of your individual abilities to analyse and synthesise.
In addition, the process of academic writing will, of itself, help you to learn, by enabling you to work with concepts and information relevant to your subject, and thereby developing your intellectual skills.
