The real value of a teacher in the same room is for immediate feedback. I'm of the opinion that lectures should be replaced with active study sessions where the teacher(s) walk the class through problems and/or help individual students through gaps in their knowledge.

Lectures can be asynchronous; rather than the teacher reinventing the wheel, let them assign students to watch the best lectures available online.

Reverse the current model, do most homework at school, and watch the lectures at home.
