PSI-Aulas Invertidas

Videos are a widely-used kind of resource for online learning. This paper uses data from 6.9 million video watching sessions across four courses on the edX MOOC platform. We measure engagement and whether they attempt to answer post-video assessment problems. 

Our main findings are that shorter videos are much more engaging, that informal talking-head videos are more engaging, that Khan-style tablet drawings are more engaging, that even high-quality pre-recorded classroom lectures might not make for engaging online videos, and that students engage differently with lecture and tutorial videos.  We developed a set of recommendations to help instructors and video producers take better advantage of the online video format.
