Id also bring some books. The message behind the gift of these resources is a simple one. There is much to be learned about teaching, but not all of it is knowledge that needs to be acquired in the school of hard knocks. I'd look carefully at the first-year teaching assignment in terms of what the new person is qualified to teach and whether he or she has experience doing so. New course preps are a part of new teaching assignments but in reasonable amounts-not three a semester or term, or five during the first year.
Confidence comes with repetition.
I'd also look at class size. The less teaching experience, the greater the trauma associated with a big class. That's not an empirical conclusion but large courses require sophisticated pedagogical skills and typically should not be part of a first-year teaching experience. I'd try to develop a climate of collegiality within the department, particularly with respect to teaching. We know that most of the ideas faculty acquire about teaching come from colleagues.
