• Title: The Crowd in MOOCs: A Study of Learning Patterns at Scale
• Authors: Xin Zhou, Aixin Sun, Jie Zhang, Donghui Lin,
• Abstract summary: We analyze a dataset of 351 million learning activities from 0.8 million unique learners enrolled in over 1.6 thousand courses within two years. We find that the time intervals between consecutive learning activities of learners exhibit a mix of power-law and periodic cosine function distribution. We demonstrate these findings can facilitate manifold applications including recommendation tasks on courses.

• Abstract: The increasing availability of learning activity data in Massive Open Online Courses (MOOCs) enables us to conduct a large-scale analysis of learners' learning behavior. In this paper, we analyze a dataset of 351 million learning activities from 0.8 million unique learners enrolled in over 1.6 thousand courses within two years. Specifically, we mine and identify the learning patterns of the crowd from both temporal and course enrollment perspectives leveraging mutual information theory and sequential pattern mining methods. From the temporal perspective, we find that the time intervals between consecutive learning activities of learners exhibit a mix of power-law and periodic cosine function distribution. By qualifying the relationship between course pairs, we observe that the most frequently co-enrolled courses usually fall in the same category or the same university. We demonstrate these findings can facilitate manifold applications including recommendation tasks on courses. A simple recommendation model utilizing the course enrollment patterns is competitive to the baselines with 200$\times$ faster training time.

  We use Process Mining Techniques to examine students' acquisition of core skills such as self-regulated learning. We applied a new algorithm in the educational domain called Inductive Miner over the interaction traces from 101 university students in a course given over one semester on the Moodle 2.0 platform. We can conclude that students who passed did not follow the instructors' suggestions exactly, but they did follow the logic of a successful self-regulated learning process as opposed to their failing classmates.

We first introduce a human-in-the-loop teacher-student architecture to isolate unlabelled data from the task learner (teacher) on the cloud-side. During training, the task learner instructs the light-weight active learner which then provides feedback on the active sampling criterion.
