British Science Festival 2013: Sugata Mitra's School in the Cloud

Sugata Mitra's 'Hole in the Wall' experiments in a New Delhi slum showed how easily children can learn using the internet, with no adult supervision or guidance. He terms this Minimally Invasive Education, and has since repeated the experiment in many different countries. This year, he has been awarded the TED prize to develop his idea further, so Ginny Smith tracked him down at the British Science Festival to find out more about how children can learn, without a teacher.
