Abstract
Active learning has been gradually focused on in recent years and introduced in various education fields because it gives better learning experience and outcomes than conventional lecture style approach. In this active learning, the quality of interaction between students, teacher and students is critically important because it decides the outcomes. Therefore, it is necessary to evaluate the interaction properly at real time and improve it. In this study, we measured and analyzed the body movement of students in group work using the sensors on smartphone. Also, we evaluated the outcomes and subjective communication quality of group work. By analyzing these three relations, there are positive correlations between the amount of body movement and the outcomes, also the evaluation of communication of group work. These results show that it is possible to evaluate the learning activity of students at real time in group work by using smartphones.
