Loved this quote, "...A GREAT lecture can be amazing and I try in my keynotes to deliver a great lecture.
But in my classes it's a different story! I rarely lecture at all anymore. I have those students for 45 hours a term - I don't need to cram anything into an hour. And I know that nobody can create 45 amazing lectures per term. In fact, after polling about 20,000 teachers and professors, the average number of great lecturers on campus seems to be 3 and the total number of great lectures any one person delivers seems to be 3."
