Exploring the Effectiveness of Student Behavior in Prerequisite Relation Discovery for Concepts
What knowledge should a student grasp before beginning a new MOOC course? This question can be answered by discovering prerequisite relations of knowledge concepts. In recent years, researchers have devoted intensive efforts to detecting such relations by analyzing various types of information. However, there are still a few explorations of utilizing student behaviors in this task. In this paper, we investigate the effectiveness of student behaviors in prerequisite relation discovery for course concepts. Specifically, we first construct a novel MOOC dataset to support the study. We then verify the effectiveness of student behaviors via serving as additional features for existing prerequisite relation discovery models. Moreover, we explore to better utilize student behaviors via graph-based modeling. We hope our study could call for more attention and efforts to explore the student behavior for prerequisite relation discovery.
