Student Engagement Detection in Online Classes
The Hong Kong University of Science and Technology Department of Computer Science and Engineering Final Year Thesis Oral Defense Title: "Student Engagement Detection in Online Classes" by WU Chi-hsuan Abstract: Online Learning is an interactive learning mode where students can acquire knowledge on various platforms without any distance barrier. With the widespread availability of internet services and the outbreak of COVID-19, online learning has drawn extensive attention. However, whether online classes are as effective as F2F classes remain questionable. Research has shown that during online courses, students often have shorter attention spans and lower concentration levels. Therefore, an engagement detection system will be essential to facilitate online learning effectiveness. In this project, we utilized multi-level features to predict engagement scores and trained the model based on the idea of Momentum Contrast (MoCo). We explored that information from I3D models, Facial Action Units, and High-level behaviors (nodding, speaking, etc.) can have a complementary contribution to the prediction. With the combination of MoCo and margin loss, our designed training process can incorporate both ordinal relationships and the in-class variety of the label. Our work facilitates future engagement prediction related research.
