I am an undergraduate physics major just finishing up my sophomore year. During this semester, I've gotten to see both ends of the spectrum of teaching methods. Which do you think is more efficient in teaching physics/mathematics? Cover a lot of material forcing students to learn some things on their own or taking your time going through material in order to really drive home main concepts but in the end cover less material. I think that if I were a teacher, I would take the "uncover a little" route, but I guess it really depends on if the class is a first exposure or advanced level.
