This document summarizes a presentation on re-conceptualizing measures of success for massive open online courses (MOOCs). It discusses the original vision of MOOCs to provide accessible education for all, as well as traditional and proposed new metrics for measuring MOOC success. These include metrics that capture student demand (e.g. demographics, engagement) and MOOC supply (e.g. number offered, languages, partnerships). It proposes that future research examine the role of engagement and goal setting in MOOC learning. The presentation concludes that intrinsic motivation for knowledge, rather than certificates, is the key driver for MOOCs and their evolution.
