Yeah, honestly if I were to do the lecturing again, I would probably get some training first.

I, like a lot of people, thought it would be relatively easy for me because I've always been relatively good at explaining things to people on an individual level. For example, at previous jobs I was the person who was there to help explain functional programming concepts to people from different backgrounds, and I was often tasked as being the "theory guy" for the junior engineers when they were having trouble optimizing.

But there were some problems with my thinking. First, sort of by definition if someone is asking for help they're kind of invested with paying attention and understanding the concept. Second, there's a pretty big difference between explaining something to a single person (especially a person you already kind of know) and an entire class of ~15-20 people, all of which are different humans with different histories and backgrounds.

I also think I took things a bit more personally than I should have. I didn't have any training or practice, and I just jumped right into the teaching part. I think I did "ok" given that, but that's not exactly reassuring..."My professor for the class I paid money for wasn't quite as bad as he could have been."
