Sir Ken Robinson gave this year’s commencement address at the Rhode Island School of Design. While it is available on YouTube, the version on RISD’s website (http://our.risd.edu/2009/06/02/sir-ken-robinson/) is much better. Robinson is a passionate critic of our education system for its failure to teach creative thinking.
Update: The RISD website does not appear to have the video of Sir Ken’s speech. You can find it here on Youtube:
