The Flickering Mind is a great book to read on this subject. http://www.amazon.com/Flickering-Mind-Technology-Classroom-L...

Oppenheimer does a great job of citing actual studies. And it turns out despite thousands of different efforts, there's little evidence to say computer technology makes a bit positive impact on education.

This isn't to say it's completely useless or that it doesn't provide overwhelming value in other industries. But I think our problems in education need to be solved in different ways. Key among them is challenging the philosophy of John Dewey.
