The general sentiment about the TEAL classes (the ones with the clickers) is that they are really gimmicky. Supposedly, it gives the professor some feedback on what concepts are unclear and pushes the students to be attentive. The problem seems to be that it's just unnecessary structure for something that's typically dynamic. It at least partially devolved into an attendance system - students used to just press in for missing friends, until recently when they had each student buy their own clicker.
