From the article: > And in a vote of confidence in the form, students in both [of two Coursera courses] overwhelmingly endorsed the quality of the course: 63 percent who completed Dr. Agarwal’s course as well as a similar one on campus found the MOOC better; 36 percent found it comparable; 1 percent, worse. I'd say that the quality of MOOCs vary, but definitely no more than the quality of courses at a formal institution.
