> making nice prepared slides like the professors in all their non-math classes do, instead of just showing up and writing on the blackboard. I mostly agreed with the conclusions in this article, but this one stood out as something not so good. I much prefer a dynamic lecture to a boring slide presentation. My favourite teacher in high school was my biology teacher. His teaching style was to sit on his desk facing us, next to his overhead projector which had a reel of acetate on it, and just write and draw as he spoke. By the end of a typical lesson he'd have a few feet of acetate filled with notes and beautifully drawn diagrams (I always wondered if he kept them, should've asked). It was engaging, and his attention to detail showed how much he cared about the subject.
