This is a funny and interesting TED Talk by Indian education scientist Sugata Mitra. He explores self-teaching and why teachers and schools don’t necessarily need to exist. One of the most important take-aways is that self-teaching only works when the kids work and collaborate with each other as opposed to individually learning. The process of talking through and exploring issues together is how the students retain information and problem-solve.
