Have you ever suggested that your students watch a particular television show in the evening? Well, if CBS succeeds, not only will you be able to make these suggestions, but you'll be able to invite students into a common chat room. (It would be interesting tonight for a civics class to meet virtually to discuss the debate.) Read TechCrunch's article about it!!
Certainly, this is possible using an online class forum, like Elluminate. But, I thought that the article was interesting. Has anybody ever actually convened a face to face class virtually to do something in the evening?
