John Sivell just sent me a link to this video of Robert Bjork talking about the importance of what he calls "desirable difficulties" in helping students not just to learn and quickly forget material but rather to retain it over the long term. I take it as a validation of 'Back to the Well' principles and feel vindicated in one aspect of my teaching philosophy as he urges teachers not to jump in and answer their own posed questions after only four or five seconds. Amen!
It is under six minutes long. I hope you'll take the time to view it and comment below.
