MOOCs navigation explorer
© 2014 EPFL
The MOOC navigation explorer allows you to interactively explore the video navigation patterns of the users. We have used the clickstream data from the first issue of the Introduction to Functional Programming course to seed this explorer with the patterns of 50'000 participants.
When doing a MOOC, averagely half of the learners just press play and watch the video. The behavior of the remaining people consists of pausing the video, speeding up and down the playing rate, as well as jumping forward and backward in the timeline. Some viewers only do few actions, whereas others are exploring the video very actively. The visualization tool we present here is aimed at making these patterns visible.
The explorer shows the overall navigation pattern or a the detailed trace for one learner. This data has been used to build an information processing index that predicts that learners who engage more with the video will also drop out less from the course. Our results will be presented at the workshop "Modeling Large Scale Social Interaction in Massively Open Online Courses Workshop" (EMNLP 2014).
