I know that I already said that I was leaving again after my last post, but I tripped across this thread and wanted to reply.
I have accreditations of different sorts and one of them happens to be a teaching certificate.
While reading Walter's story, I began to smile. During my time studying, I had a Psych Prof who, although highly unorthodox in his approach to teaching, was the most humorous and effective teacher I ever had.
One day at the beginning of an hour and a half scheduled class, near the very end of the term, he posed two short question, and without hearing anyone's response, he replied to his own questions with a short statement:
He said, "I want every individual in this room to think about the very best teacher you have ever had, and the things that he or she did that made them special..." (about 3 minutes went by, then he said) "Now I want every individual in this room to think about the very worst teacher they ever had and mentally list the things that made them so horrible as a teacher."
After another three minutes he said, "For your entire teaching career, avoid doing ANY of the things that the second teacher did"... he got up from sitting on the desk in his usual position, smiled, and walked out of the class. He never showed up for class again, but in the last two or three classes that we had left (and felt compelled to come to), what do you suppose we discussed?
The question the OP raises for me is, "what did the teacher learn in his own class?"
