Coming up this Saturday afternoon at 3pm on American RadioWorks, correspondent Emily Hanford examines the history and influence of the University of Phoenix, one of the nation's largest colleges, and explores how Phoenix and other for-profits are shaping the future of education. For-profit colleges have deep roots in American history, but until recently they were a tiny part of the higher education landscape. Now they are big players. More than one in 10 college students attends a for-profit. The rapid rise of these career-oriented schools has provoked heated debate, opening up new conversations about the costs, quality and purpose of higher education.Tune in to 90.5FM on January 5, 2013 at 3pm hear this installment of American RadioWorks!
