For the fourth time today, I had an expert skype in to talk to one of my classes. Three experts, four visits (because one was kind enough to skype twice).
It's really cool, especially for this more advanced course, because the experts are people whose work we're reading, and the students get to see these folks as human beings, thinking their way through questions, asking the students questions, thinking together.
Each time, the students have been quiet, sort of shy, especially at first. But each time they've also talked afterwards about how much they learned, and how cool it is.
It's like Star Trek or something! From across the country!
