MOOCs for (a Year's) Credit

Arizona State University, in partnership with edX, this fall will begin to offer credit-bearing massive open online courses at a fraction of the cost of either in-person or traditional online education.

ASU’s faculty members will create about a dozen general-education MOOCs, the first of which -- an introductory astronomy course -- will launch this August. Anyone can register for and take the MOOCs for free, but those who pay a $45 fee to verify their identity can at the end of each course decide if they want to pay the university a separate, larger fee to earn academic credit for their work.

By fall 2016, ASU anticipates it will offer enough MOOCs so that students can complete their entire freshman year online through what edX and the university are calling the Global Freshman Academy.

After completing the courses, students can receive a transcript from ASU showing that they have earned enough credits at the university to transfer to a different program or institution as sophomores. Since the university stresses the MOOCs are just a new form of delivering courses it already offers, the transcripts won’t specify which type of course -- in-person, online or massive online -- students enrolled in to earn the credit.
