Recommending Remedial Learning Materials to the Students by Filling their Knowledge Gaps, invited talk at WI2016

Their research mainly concerns the online education scenario. They proposed a method to identify gaps in students’ knowledge of online courses and recommend students with helpful remedial materials. Specifically speaking, the knowledge they try to capture is based on a knowledge tree, in which the leaves are topics from a domain taxonomy(automatically built from the syllabus). The knowledge gap is identified based on the feedback from course quizzes questions. If a student has a low performance score in a topic, we may presume that this student has a knowledge gap in this topic. Thus we can provide him/her recommendation materials by emailing to help fill the gap.

An A/B test on 910 students has been carried out to evaluate this approach. The improvement of average score on exam indicates the effectiveness of proposed recommendation method.
