“We’re at a point in history where it’s actually possible for anyone to teach anyone else, regardless of geography or status,” said Smithmier. “Each of us has the potential to be contributors, to share our knowledge to make education better and more effective, and we want to help fuel that revolution. Sophia connects people wanting to learn with those willing to teach.”

Sophia announced on May 19 that it acquired Guaranteach, a web-based service that provides tens of thousands of tutorials and assessment tools. Guaranteach had previously offered its collection of tutorials on a pay-per-use basis, but Sophia will offer them at no cost.

The acquisition greatly increases the depth of Sophia’s offerings. Guaranteach’s math program includes more than 60,000 quiz questions and has been used in more than 50 schools already, including the School of One in New York. Sophia plans to use Guaranteach’s model to further develop English and science tutorials.
