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.

The move is bound to generate a lot of controversy for News Corp., the media conglomerate owned by Rupert Mudoch.
