Sugata Mitra
Sugata MitraTrustee

JIn 2019, Sugata Mitra retired as Professor of Educational Technology at Newcastle University and is Emeritus Professor at NIIT University in Rajasthan, India.

He is best known for his Hole in the Wall experiment, where a computer was embedded in a wall in an Indian slum and children were allowed to freely use it. The experiment showed that children could learn to use computers without any formal training. Professor Mitra termed this Minimally Invasive Education.

Since 2006, his work at Newcastle University resulted in the development of Self-Organised Learning Environments for children. SOLEs, as they are called, showed that groups of children, presented with an interesting question, can learn almost anything by themselves. In 2010, he developed the Granny Cloud – where retired teachers provide the impetus to Self Organised Learning by children, anywhere in the world, over the internet.

In 2013, he was awarded the first $1 million TED prize to create seven Schools in the Cloud to study learning as emergent phenomena in an educational self-organising system. The results question the ideas of curriculum, examinations and the meaning of ‘knowing’ in a digital world.
