Two higher education experiments have received high-profile financial boosts. Jack Welch, the former CEO of General Electric, has invested more than $2 million for a 12 percent stake in Chancellor University, a for-profit college that was formerly Myers University, in Cleveland, the Wall Street Journal reported. In return, Chancellor will name its M.B.A. program for Welch. And on Monday, 2Tor, which last fall unveiled plans to help the University of Southern California take its master's degree in teaching online and ramp up its scale, announced that it had received $10 million in venture capital funds.
