> We spend an hour learning a concept, and only practice using it when we get home.

This is why I'm a fan of what the Khan Academy[1] is striving to do. It flips this pattern around, with more instruction at home and practice when with the instructor. The teacher can then spend less time introducing a topic and instead working through the process with individual students.

Watching Khan's TED talk[2] is pretty inspiring.
