The challenges and opportunities in creating small sub-groups within a larger community of online learners, specifically in the MOOC context. The challenge of most MOOCs today is that they are comprised of a large, disparate, atomized collection of individuals. This collection sheds members rapidly (though not consistently) throughout the course of the MOOC.
So how can we put people together in groups to help make the overall collection more cohesive? What attributes might we look for? What techniques might we use and how might we reform groups if there is too great an attrition from the initial cohort?
