Jamie,
Lost or wasted class time is not good for anyone. I like to arrive before students, have copies, handouts, or instructional aids organized for passing out. If PPT is to be used, I want to test the computer, projector, and a quick run through of the slides. As students begin to arrive, I like to feel free to chat with students, answer questions -- sort of "just be there" for relating and establishing positive communications.
