We did the coolest thing today, thanks to Susan (who sometimes comments here). We had a Skype session with her and my class, and we learned tons, and it worked great.
It also made me acutely aware, in ways that I sometimes forget, how shy and quiet many of my midwestern students are. They'll chat away with a ton of questions one on one, but in a group of four or more, especially when they don't know someone, they're a whole lot quieter.
Still, they tell me they had a great time and thought the session was really valuable for them.
I think I'm making it to the 21st century after all!
