Creative Nonfiction Writing - HELP!

I'm starting a brand new course in Creative Nonfiction Writing in September for 10-12th graders. Does anyone have any advice on how to structure the course or reading suggestions? I know I want it to be a very collaborative and community based class, but I need help with what types of writing to cover and various genres (memoir, travel writing, biography/autobiography, etc.). Any help would be GREATLY appreciated!
