Some time back I talked about TED Talks. These talks are still some of the most exciting, provocative presentations on the web and I am surprised by the number of people who have not discovered them yet.
One of early most popular talks is from Sir Ken Robinson from 2006 that has been downloaded 4 million times: Sir Ken Robinson says schools kill creativity.
If you have seen it and like it - you make like a more recent talk by Ken Bring on the learning revolution!.
Or take a look at his recent book The Element:How Finding Your Passion Changes Everything
