xMOOC, cMOOC, DOCC or BOOC: What's in a name?

Tomorrow is the official start of the Videogames and Learning Coursera MOOC developed by Kurt Squire and Constance Steinkuehler at University of Wisconsin Madison.  In this post I compare the pros and cons of Coursera's more expository "xMOOC" format with the connectivist "cMOOC" format  advanced by Siemans and Downes and show how the the more modest "big" format of IU's Big Open Online Course is turning out to be a useful interim context for design-based research of hybrid formats for future massive courses that can exploit the advantages of these very different formats while minimizing the negatives.
