Flexible learning removes barriers relating to time, place, and pace. While time management skills have been identified as necessary for learners to take advantage of flexible learning, relatively little is known about the temporal dimensions of flexible learning and how gender might relate to temporal flexibility and its perceived benefits. To address this gap, we analyzed data from 380,000 students participating in two massive open online courses to create a model that predicts course completion likelihood from learner time management behaviors and gender. Results supported most a priori assumptions. Successful course completers logged in frequently, devoted longer amounts of time to each session, moved quickly through course materials, and completed coursework early. However, consistent study was associated with lower course completion likelihood, and women benefited more from reduced consistency. These findings suggest that temporal flexibility may especially benefit women.
