A Prospectus of about 750 words (or 1000 at most) should answer the following questions:
Organization of the Prospectus:
A. Title: it should be informative and helpful in pinpointing the topic and emphasis of your study.
B. The body of the prospectus: this section should concentrate on addressing questions 1-3 above. The goal of this section is both to describe the project and to "sell" the reader on its potential interest and significance.
C. A section breakdown: This can either be a formal section, in which each section is described in turn in about a paragraph's worth of text, or it can be done more narratively, in which the whole project is outlined as a more seamless story. Either way, it should address question #4, above.
