Free professional development – university courses

Looking for some professional development that costs nothing? How about taking refresher college classes, or classes just for the fun of it? For free?

http://academicearth.org/ provides lectures from world-class universities and colleges. You can find individual lessons on a particular topic, or an entire lecture course. You can also sign up to get emails whenever new materials are added.

You need a high speed internet connection (dial-up just can’t handle the video).
