For nearly two years, Joel I. Klein helped Rupert Murdoch and News Corporation weather a phone-hacking scandal at the company’s British tabloids with the promise that he would eventually be able to return to the role the company hired him for: to spearhead News Corporation’s new venture into the public school market. That day has finally come.

On Wednesday at the SXSWedu conference in Austin, Tex., Mr. Klein, the former chancellor of New York City schools and the current chief executive of Amplify, News Corporation’s fledgling education division, will take the stage for a surprising announcement. Amplify will not sell just its curriculum on existing tablets, but will also offer the Amplify Tablet, its own 10-inch Android tablet for K-12 schoolchildren.

In addition to tablets and curriculum, Amplify will also provide schools with infrastructure to store students’ data.

“When I left I was convinced of two things,” Mr. Klein said of his tenure as chancellor of New York schools. “If we didn’t see a dramatic technological change, we were not going to be able to move this country forward,” and “second of all, that the private sector had to get much, much more involved.”
