Steve Hargadon is the Charlie Rose of technology, learning and teaching. On his website, the Future of Education, he has interviewed everyone: from Clay Shirky to Diane Ravitch to Ken Robinson to Howard Gardner, and nearly everyone in between. He’s been at the center of open education resources, Web 2.0, and social networking for as long as anyone. He is a master of virtual live events. His Teacher 2.0 website is essentially a megasized personal learning network for teachers. In this video, crowdsourcing pioneer Howard Rheingold talks with Steve about "rethinking learning."
