In recent years, student-driven learning has been used to improve education in schools. Project-based learning (PBL) is often adopted to facilitate student-driven learning. In PBL, it is very important for the learners to have successful experiences when participating in team activities. However, every team activity in a PBL class is not always successful because learners with poor performance, caused by factors such as low motivation and weak problem-solving and communication skills, often participate in the class. With this in mind, our goal is to develop a system to support team-based activity within a PBL course using information technology. As the starting point of the research, we investigate how to use a basic team-based activity support system in a PBL course.
