My friend Neil posted this article earlier today. Got me thinking. Enough so to post again after a couple of months. The article is about Harvard's popular CS50 course. David J. Malan took over and redesigned the course in 2007 and it's been his ever since. This year, Malan is on sabbatical and the course is being taught by Henry H. Leitner who was one of the instructors prior to Malan's reworking of the course.

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.

Saw this article in the New York Times yesterday. It's been making its rounds. There was some discussion in some of the CS Ed related online groups, my friend Alfred Thompson posted his take here, and when my daughter, a professional SWE at Meta for close to a decade came over for dinner yesterday, she brought it up. I haven't posted in a while so I figured I'd add my two cents.
