I thought it was interesting how you divided instructional into three helper categories. I was glad to see you had a section for communication. Technology seems a bit broad; what do you have in mind?
I like the teacher, student, and lesson helper categories too. I think I would have pushed them up a level to be the main categories to reduce some of the size of the system a little, but that is just me. The system is really clear the way it is now.
