Capella Education Co., one of the nation’s largest for-profit higher education providers, ventured into unaccustomed territory Wednesday by putting 25,000 free academic tutorials online through an education site it owns,

Capella, which operates the 37,000-student Capella University, completed its aquisition of Sophia this month. Sophia is a new site that offers educators free access to lessons on thousands of topics. The lessons are reviewed by Sophia staff and rated by users.

“It’s good stuff that’s been vetted for academic veracity,” said Steve Anastasi, interim CEO of Sophia. He notes that educators and parents routinely log millions of Google searches for “help with math.” On Sophia, the search becomes a bit more orderly and fruitful.

For Capella, the undertaking “generates goodwill,” said Mike Buttry, spokesman for the Minneapolis company. Capella leaders see it as a way to promote K-12 education, which ultimately creates more business for its university.
