Washington: The man behind India's low-cost Aakash tablet and an Indian American professor are listed among Forbes 15 "classroom revolutionaries" who are using innovative technologies to reinvent education for students and teachers globally.

Suneet Singh Tuli, the CEO of Datawind, the maker of Aakash, and Massachusettes Institute of Technology professor Anant Agarwal figure among the education innovators who are "harnessing a slew of disruptive technologies to change everything from the way we teach grade school math to how we train the next generation of teachers".

Tuli is the "mastermind" behind the world's cheapest tablet computer Aakash, "which has the potential to revolutionise educational access in the developing world", the US business magazine said.

Datawind has a backlog of "millions" of orders for the 35 dollar Aakash tablet. The publication quoted Tuli as saying that "I don't care about creating the iPad killer. I care about the 3 billion people who can afford this device".

Agarwal, 53, a professor of computer science at MIT is also the President of edX, the new combined online offerings of Harvard, MIT, the University of California at Berkeley and the University of Texas. Over 400,000 are currently enrolled in the education programme.

"It is insane. We've created dramatic access to learning for students worldwide," says Agarwal who took the helm in May of teaching to the masses. "By reinventing online learning, we can dramatically improve what we do on campus."
