standing back from your subject and weighing up pros and cons.
A dissertation is a subject you chose for yourself.
The first usage of the word in the English language in 1651 also gives a useful starting definition: “an extended written treatment of a subject”.
Do reference popular literature or WWW sites if you can help it (this is a matter of style more than anything else -- you want to reference articles in refereed conferences and journals, if possible, or in other theses).
Also in the introduction, you want to survey any related work that attempted something similar to your own, or that has a significant supporting role in your research. You cite the work in the references, not the researchers themselves. Thus, the model you develop and write about (and indeed, that you defend) should be one that has lasting value.
There are some obvious differences: an essay is relatively short – usually 1500 to 2500 words – and you are told clearly what to do by someone else.
For example: Describe and evaluate major theories of globalisation.--spaf] Let's revisit the idea of the thesis itself. The dissertation is a formal, stylized document used to argue your thesis.The thesis must be significant, original (no one has yet demonstrated it to be true), and it must extend the state of knowledge.The phrase telling you that you will have to lift your game to write a successful dissertation.‘Scholarly method’ means that you will be expected to do more and better reading and research than for a standard undergraduate essay.The progress of science is that we learn and use the work of others (with appropriate credit).Assume you have a technically literate readership familiar with (or able to find) common references.Another useful clue is found in the Latin origin of the word – dissertation comes from a Latin word ‘dissertare’ = ‘to debate’. A discussion involving different points of view or sets of ideas.A dissertation will therefore not only examine a subject but will review different points of view about that subject.The dissertation itself should be structured into 4 to 6 chapters.The following is one commonly-used structure: Let's look at these in a little more detail Chapter I, Introduction.
