Using computers to improve education has been one of the great unmet hopes of the technology revolution. Billions have been spent and machines have deployed everywhere, but most fundamental measures of student achievement haven’t particularly improved.

Maybe we’ve been looking in the wrong places for improvement. In at least one success story, cloud-based computing systems appear to help free teachers focus on their core job of teaching students, instead of entering data about them.

Clever, a San Francisco company, recently put its online software into 15,000 schools. That is slightly more than one in nine American schools. Not bad for a product released less than two years ago.
