Deadline is early November 2003. The complete Application (pdf) NSF Guidelines for Application (html)
IMPORTANT: Here are two parts of the proposal that I and Amanda Gable can help you with:
Proposed Plan of Research Form (NSF Form 306):
In a clear, concise, and original statement, describe research topics you may pursue while on fellowship tenure, and include how you became interested in these topics. Your statement should reflect your own thinking and work, demonstrate your understanding of research principles necessary to pursue these interests, and explain the relationship to your previous research, if any. Present your plan with a clear hypothesis or questions to be asked by the research. If you have not yet formulated a plan of research, your statement should include a description of one question that interests you and an analysis of how you think the question may best be answered. A listing of courses alone is not sufficient. Research topics discussed in your proposed plan may be used in determining eligibility. Type single-spaced using 10-point font size or larger. There is a 2-page limit, including references.
Previous Research Experience Form (NSF Form 1259):
Describe any scientific research activities in which you have participated, such as experience in undergraduate research programs, or research experience gained through summer or part-time employment or in work-study programs, or other research activities, either academic or job-related. Explain the purpose of the research and your specific role in the research, including the extent to which you worked independently and/or as part of a team, and what you learned from your research. In your statement, distinguish between undergraduate and graduate research experience. If you have had no direct research experience, describe any activities that you believe have prepared you to undertake research. At the end of your statement, list any publications and/or presentations made at national and/or regional professional meetings. Type single-spaced using 10-point font size or larger. There is a 2-page limit, including references.
When/If you don't get the award, you should request the reviews from the panel. This will give you concrete information about how your application was viewed. But you must request these reviews. Based on the 2003 results, it appears that your research statements should be as sophisticated as you can make them. Again, if the process is not working for you in your senior year, you get a second shot in the first year of grad school. And the second time round, the whole process will be easier for you to complete. All the 2003 GT winners were already in grad school, making good strides towards their thesis research.
