Call for ideas

What's my novel about?

Imagine:

A public school teacher, very dedicated, very hard working, in a school much like mine (ok, so yeah, a lot of it is fairly autobiographical), but after 5 years of trying to work miracles within a system that suppresses much innovation and generally sets up students for failure, he's had enough, and decides to take things into his own hands.

Interpret that as you will.

So ok - quick. Give me some ideas for my novel, if you can. Thoughts, plot suggestions, what you'd like to read about, etc.

I'm up to about 5,000 words. Which means I'm very behind, but 10% of the way there!
