This is a wonderful short presentation by Dan Meyer at TedxNYED (I'd love to do one of those events here at PSU). There is so much packed into 12 short minutes just screaming to be discussed and explored. One of his main points is the potential problems of practice related to teaching from and relying strictly on textbooks -- not that he doesn't say textbooks are evil or anything, shows how to better take advantage of them in a 21st century world. Watch it and see if it moves you to take the time to react. I'd love to hear ideas and reactions.
