Teaching is a very personal thing.
Even though you do it in front of a group of students, there is a feeling that your colleagues must not intrude and it's something done in a closed room between consenting adults. The first trick in teaching improvement is to get people over this feeling, And that's really the hardest hurdle. Once you cross it, then it's obvious that teaching is like everything else-it's good to look at yourself doing it and see. The advice given to me by members of the CTL staff was highly instrumental in making me a more charismatic and effective teacher. There's no other way of doing this that would be nearly as constructive.
