Prerequisite-related MOOC recommendation on learning path locating

摘要

Prerequisite inadequacy causes more MOOC drop-out. As an effective method interfering with learning process, existing MOOC recommendation is mainly about subsequent learning objects that have not been learned before. This paper proposes a locating-based MOOC recommendation method with consideration on prerequisite relationship. It locates the target learner’s learning paths and provides prerequisite recommendation for unqualified learning objects and subsequent recommendation for the qualified objects. Experiments on real-world data show both the accuracy and learning performance improvement of our recommendation method.
