Mathieu Plourde on 19 Apr 13"The relatively low completion rates of learners have been a central critique as MOOCs grow in popularity. This focus on completion rates, however, implies a monolithic view of disengagement that fails to acknowledge alternative forms of participation in MOOCs. Identifying subpopulations of learners based on their longitudinal engagement with the course allows MOOC designers to target interventions and develop adaptive course features. We develop a simple, scalable, and informative classification method that identifies four prototypical engagement trajectories: Completing learners, who complete the majority of the assessments offered in the class; Auditing learners, who do assessments infrequently (if at all) and engage instead by watching video lectures; Disengaging learners, who do assessments at the beginning of the course but then have a marked decrease in engagement, generally in the first third of the class; and Sampling learners, who enter and exit the course quickly, watching a minimal number of videos at some point during the course."
