The University of Texas is planning today to officially join edX, which offers massive open online courses or MOOCs. Because the Texas announcement involves an entire system, it represents a major expansion of edX, which was founded by two universities (Harvard University and the Massachusetts Institute of Technology) and was later joined by one other (the University of California at Berkeley). Coursera, another major MOOC provider, has been adding universities at a rapid pace. The Texas system plans to focus on general education and introductory-level courses for its MOOC offerings. Bloomberg reported that the University of Texas is paying $5 million to join edX.
