Do schools kill creativity?

I have watched this TED talk several times and each time it makes me laugh out loud. But the message is very serious - we need creative people and schools are killing creativity. At a time when the new Bloom's taxonomy has creativity at it's highest point, we certainly need to take a lot of what Sir Ken Robinson says on board. Most children would benefit from being encouraged to have a go, make mistakes and learn from them. Every advance society has made has come about because people were creative, took chances and came up with new ideas. Listening to this makes me even more positive about the IB, where students have to have a balance between languages, science and maths, humanities and the arts. In so many other systems the "non-academic" subjects can be dropped as they are not seen as valuable or having academic rigor.
