Teaching Or The Value Of Doing Something Different

I sat through a lesson last night from an old school teacher. It was straightforward. He was somewhat prepared. The message was concise and hammered home.

All I wanted was something different. I wanted a tangential story, a little fire, some thing else.

One of the big questions in life is when to switch? When to change? When to try something different? You see it in sports. You see it in policy. You see it every day at an individual level.

So here is another exam question:

A professor has taught a class for 20 years. He has numerous exam questions, homework problems, assignments, PowerPoint slides etc. etc saved up. He gets average to above average reviews every year. He cares about teaching, but it is not his main source of income. He has some radical ideas that could make his class better or his class worse. These ideas would take time to develop but might also save him time in the future. What does he do?
