Template for a proposal:
Quote-make it some quote that is relevant to writing or the writing process. It could be serious and inspirational or of another variety (the one I used last year was "the trick to writing is getting that voice inside your head that says 'thats no good, stupid' to shutup long enough for you to get something down on paper"-Kate Grenville. The one I included in my reflection statement was "What is written without effort is generally read without enjoyment").
Introduction-make it brief and justify your reasons for taking the course and what you hope to achieve by the end of it (growth as a writer and crap like that). Also briefly introduce your medium and loose idea.
Body-In this you will discuss several aspects of your work. Use a seperate paragraph for each.
Medium-Identify your medium and justify why you chose it (i.e. you are strong in this area, or it is an area that interests you)
Idea-Identify the general gist of what you will be writing about, even if it is just the area. Talk about why you chose this, and how your medium will aide in you exploring this idea
Methodology-How you will go about constructing your major work. Include areas such as research (into both the area AND the medium), planning, inspiration, and any mentors or people you will turn to for advice.
Conclusion- Sum up your intentions in no more than 1 or 2 sentences and reaffirm what it is you hope to achieve by doing this course (in different words to what you used in the intro, but make sure you assert that this course is a 'wonderful opportunity to explore your passions and interests')
