Perhaps a bit of a pretentious title, but this list of 100 Free Online Lectures that Will Make You a Better Teacher does look like a nice collection of helpful thoughts and ideas. This list of videos contains a wide variety of content – from serious lectures to short clips from the Late Show. I haven’t watched very many of them, but I think it’s a list worth bookmarking and coming back to in the future. Let me know if you find any gems that you especially like!
