Hi David:
Very true. Students are not likely to feel comfortable asking their instructor a question before class if they observe s/he running around, making last minute copies, shuffling papers, etc. That's chaos and I don't think many thrive in that kind of environment.
We owe our students the benefit our full attention, and for class, fully prepared and ready to go on time, but if we're just on time, we're probably late in a preparation sense.
Regards, Barry
