Time for another SIGCSE - the big Computer Science Education conference. This time in St. Louis. St. Louis Arch This is something like my 10th SIGCSE and the fourth I've attended with my daughter who's in her first year as a grad student, pursuing her PhD in CS with a focus on education. At this point, I think she knows more people here than I do. Actually, that was something I was thinking about.

History is a funny thing. They say it's written by the victors but even when the "good guys" win, the history taught is often, let's say, incomplete. Back in school we'd learn about all sorts of feel good American equality stuff but how many learned about Black Wall Street and the Tusla Race Massacre? I've knew about the Green Book and Sundown Towns years before the "Green Book" movie and was shocked when I did learn about the towns, how recently they've existed and how many existed up up north.

Finally we get to teachers observing teachers - what Mark was writing about to begin with. These observations could be a one off, for a few days, or even through a full course. This could also be a team teaching situation but to be honest, I think that's a different beast. If I'm team teaching a course with someone, true, I can learn from them if and when we do joint preperation and things like grading and yes, I can learn something by being in the room when they're leading some activity but it's not the same since at that time, my job isn't to observe, my job would be to do something else to enhance the lesson - direct student support perhaps.
