I agree that it's very easy to tell between the students of a great teacher and a bad teacher. I've found that the best teachers are ones that came from industry, they did their work, and then went into teaching. That's why my school's engineering department is great, as is one of the physics teachers who sadly only teaches me once every 2 weeks.
