Here's a great video of a 20 minute talk by Ken Robinson, former Professor of Arts Education at the University of Warwick, on how schools kill creativity.
Reasons why this is worth seeing:
(1) It's LOL funny. (I had dealings with Ken Robinson nearly 20 years ago, and I knew he spoke very well, but never dreamed he'd be so good at stand-up!)
(2) There's an interesting and provocative message: that creativity should be as important as literacy and numeracy in the curriculum
(3) The parent website TED (Technology, Entertainment, Design) is a useful source of videos of inspiring talks on a range of subjects
(4) It's a reminder of how good a good lecture can be - useful to remember when people cite "the lecture" as the archetype of a passive-receptive transmission-of-knowledge pedagogy which has no place in the Web 2.0 world.
