If you are a Ken Robinson fan, then you'll like this new version of several of his earlier talks. This was presented just a couple of weeks ago as part of the debut of TED talks on the US public broadcasting system (PBS).
There are plenty of messages here - and well worth the 20 minutes you'll invest in watching this. There are messages about learning (and teaching), and messages about investment in professional development. I'll leave the rest up to the knight of the realm - it's his talk and not many deliver a message better than this man.
