Today I did the "guest lecturing" I've posted about for the last couple of days. At the request of a commenter I did make a 745MB digital audio recording of the talk, but I doubt it will be worth very much without the visuals--pictures, coins, stamps, and uniform insignia--that I passed around at different times during the talk.
I spoke to 4 classes and recorded the third one. Wouldn't you know it, that's the one where I made mistakes! I don't know why, but I kept referring to the cathedrals in Cologne and Coventry as "temples" in that class, something I didn't do in any other class. Maybe I was just spooked by the recording device, who knows.
Still, the students at least paid attention and I didn't see any reading books, doing work from other classes, or any other behaviors that would indicate that they weren't interested and/or weren't listening. Each class asked different questions, which often triggered new memories of stories nana used to tell me.
All in all, the talk seemed to be well-received by the students. A couple even saw me after school--students I didn't even know--and they told me how much they liked this point or that that I had mentioned. That was very rewarding.
