Schools vary the due dates of their assessments of their own accord; I had my Proposal due about three-quarters through Term 4 in 2006. Some people from other schools whom I met at a study day in late February of last year hadn't been asked by their teachers handed in theirs yet.
Back on-topic here, I had a similar structure for my proposal. Your intended program of research is essentially the plan you have in regards to how you'll conduct your research into your themes and concepts. Such as how you intend to usse a variety of media (e.g. library books, audio information, as well as online info, etc.) in order to gain a greater understanding and more substantial insight into your ideas.
With the fourth dot point, I'll be completely frank in that I have very little idea what to help you with there (although waking up 15 minutes ago with a massive hangover does NOT help
), although considering that philosophy deals with a particular branch of knowledge or truth, I'd say maybe discuss how you want to use your MW as a vessel to explore the boundaries of the truth of the concepts that you're depicting in your piece, or if you plan to have your Major Work as a piece that stays within the boundaries of the concepts but explores the meaning behind the concepts, etc. etc. Blah blah. *scratches chin*
The eventual structure basically talks about not only what medium you'll end up choosing for your MW, but also its skeleton. So if you're choosing a short story, but also twisting the conventions of the short story genre by including post-modernist snippets to add deeper meaning and allow for more diverse interpretation (I'm just pulling this all outta my ass at the moment), talk about that. Also, here is where you can talk about plot or underlying concept(s), and how you'll use certain parts of the MW to accentuate particular parts of the storyline, etc. etc.
Hope I helped? And good luck for your Proposal!
