The Rise of Informal Knowledge and the Teacher’s Evolving Role

William H. Zaggle, educational technology & change, Jun 16, 2011
Commentary by Stephen Downes

I think William H. Zaggle could have drawn it out a bit more clearly, but what I really want readers to see is the video of a robot balancing on a ball. What's significant about this robot is not that it has been given instructions on how to balance, but rather has learned (by training a neural net) through trial and error. Which is exactly the same sort of effect we are trying to achieve with informal learning. "It is as if we can easily measure a person’s ability to balance standing on a ball, but still know that only practice and failure and experience and practice and some successes followed by more practice can ultimately make him or her better at it."
