Wellesley College is joining edX, one of the primary providers of massive online open courses, or MOOCs, The Boston Globe reported. Anant Agarwal, president of edX, said that the college will try to preserve some of the features of liberal arts colleges in its four MOOCs to be offered through edX. The courses will allow instructors to divide classes into small groups for discussions. "We want to create the aura of a small-group setting, so that students can discuss among themselves," Agarwal said. To date, research universities have dominated the MOOC space. edX's other members are Harvard University, the Massachusetts Institute of Technology, the University of California at Berkeley and the University of Texas System. Of the 33 institutions that offer MOOCs through Coursera, only one -- Wesleyan University -- is a liberal arts college.
