I am glad to here Mke saying that today is more about communication and collaboration. Social networking and communication in sooo many ways today for students as well as teachers is what is really visible.
So from the history of the internet to this refocussing on learning - a great interview from Michael Wesch about harnessing collective intelligence rather than teaching content. He is an advocate of 'anti-teaching', seeking too inspire with god questions. Google becomes a tool for testing possibilities. Social media is also about learning possibilities. But don't get it wrong - it is also about more work! more commitment! more active involvement in collaborative learning.
