Fill Students' Knowledge Gap by Recommending Remedial Learning Materials

Abstract

Identifying and filling the knowledge gap is one solution to improve students' learning performance. Several challenges are involved, such as how to identify the gap and how to fill the gap. In this paper, we propose to identify students' knowledge gap at the early stage by tracking their in-class emotions, and fill the gap by recommending remedial learning materials on time. The framework and workflow have been described in details in this work.
