If you need to write an abstract for an academic or scientific paper, don't panic! Your abstract is simply a short, standalone summary of the work or paper that others can use as an overview.  An abstract describes what you do in your essay, whether it’s a scientific experiment or a literary analysis paper. It should help your reader understand the paper and help people searching for this paper decide whether it suits their purposes prior to reading. To write an abstract, finish your paper first, then type a summary that identifies the purpose, problem, methods, results, and conclusion of your work. After you get the details down, all that's left is to format it correctly. Since an abstract is only a summary of the work you've already done, it's easy to accomplish!
The thesis abstract or summary is what will be read first, to give an indication of the parameters of the study, its depth and breadth, its context and the scholarly contribution it makes. It may be the basis on which a prospective examiner agrees (or not!) to examine your thesis. It is important that it is written in a concise and focussed manner so that it identifies the salient features of the research, the problem or research question, the approach adopted, and its findings. In general the thesis abstract is about 300 words, and for Monash doctoral theses, no more than 500. (Check the norm in your discipline.)
