Isn’t it delightful when someone does something good for everyone? That is how I feel about MOOCs, massive, open, online classes. This allows teachers to polish and perfect lectures, to use other people’s lectures, and to keep the class time to interactions, to working together, arguing through difficult concepts. Work alone when you are alone. Work together when you are together. Here is the person to follow, the completely brilliant Mohamed Noor. Here are his thoughts about MOOCs. He had a lot of help getting great lectures up there, but the inspiration came from him. Teaching is undergoing a revolution right now. Find what new techniques work for you and jump aboard.
I have been working with another kind of online teaching: Wikipedia. I’ll be writing more about this in the future, but for now, here is the link to my course. Mohamed is right that getting images that are not restricted is a challenge. One thing we can do about that is to upload images of our favorite organisms to Wikimedia with their Wizard to do it. Please choose the most liberal copyright. I pick that you can do anything with my images so long as you credit me for taking them.
