I gave a fifty-minute lecture on the lambda calculus for a class last week. It was a topic I understood very well, but had never taught to someone else before. The length of the lecture was daunting enough, but I was surprised at how difficult it was to create a lesson plan. I could clearly see the ideas and their implications in my mind’s eye, but it was hard to impose an order and a rationale on them that would make sense from the perspective of someone new to the material.
I feel like an unacceptable portion of my class experience has been learning the material on my own. Granted, being able to learn something on my own is a good skill, but that’s not what I’m paying these people for. I’m sick and tired of walking out of lectures wanting my 50 minutes back. It’s such a relief to get a prof that I can understand. When will they learn that even though you have a PhD in something, you aren’t necessarily qualified to convey that knowledge to others.
