Education scientist Sugata Mitra tackles one of the greatest problems of education — the best teachers and schools don’t exist where they’re needed most. In a series of real-life experiments from New Delhi to South Africa to Italy, he gave kids self-supervised access to the web and saw results that could revolutionize how we think about teaching. (Recorded at TEDGlobal 2010, July 2010 in Oxford, UK. Duration: 17:14)
