ABSTRACT
Statistics show that, on average, each user of Massive Open Online Courses (MOOCs) uses "jump-back" to navigate a course video for 2.6 times. In this work, employing one of the largest Chinese MOOCs, XuetangX.com, as the source for our research, we study the extent to which we can develop a methodology to understand the user intention and help the user alleviate this problem by suggesting the best position for a jump-back. We demonstrate that it is possible to accurately predict 90% of users' jump-back intentions in the real online system. Moreover, our study reveals several interesting patterns, e.g., students in non-science courses tend to jump back from the first half of the course video, and students in science courses tend to replay for longer time.

Smart Jump: Automated Navigation Suggestion for Videos in MOOCs
WWW '17 Companion: Proceedings of the 26th International Conference on World Wide Web CompanionStatistics show that, on average, each user of Massive Open Online Courses (MOOCs) uses 'jump-back' to navigate a course video for 2.6 times. By taking a closer look at the navigation data, we found that more than half of the jump-backs are due to the '...
Context counts
Massive Open Online Courses (MOOCs) require individual learners to self-regulate their own learning, determining when, how and with what content and activities they engage. However, MOOCs attract a diverse range of learners, from a variety of learning ...
Effects of In-Video Quizzes on MOOC Lecture Viewing
L@S '16: Proceedings of the Third (2016) ACM Conference on Learning @ ScaleOnline courses on sites such as Coursera use quizzes embedded inside lecture videos (in-video quizzes) to help learners test their understanding of the video. This paper analyzes how users interact with in-video quizzes, and how in-video quizzes ...
