Abstract
Educational institutions seek the development of co-creation skills that can resolve complicated social issues in cooperation with others. Thus, we built the Real-time Reflection (RTR) system, which can be self-reflective on a student’s experience in real time by using ICT. In this study, we outline the results of research on and analysis of the impact that RTR has on the collaborative creation activities of the group after introducing the RTR into a practical lesson exercise design. In class, groups of students designed a planning and sales promotion tool for specialty products for a PR event. We were asked to evaluate their designs and PR planning by showing them to experts. The results of examining the correlation between the evaluation by experts and the use frequency of the RTR of the variation showed a tendency toward a positive correlation. In addition, there is a strong correlation that groups tend to reflect repeatedly on a particular learning phase, including all the members of the group. We clarified that co-creation styles and the effect of learning are changed by reflection on learning phases.
