It is not difficult for residents to understand the knowledge of disaster prevention. However, people sometimes cannot easily use such knowledge to take safe evacuation actions. For example, it is quite difficult to decide safe evacuation action taking account of various preconditions such as hazardous areas and height of the location in the building. In the present study, a tool for disaster prevention learning is developed as a flow diagram to select an appropriate evacuation action specifying the preconditions along the flow. In this study, we propose a learning support method with the selection diagram using reverse-thinking problems, which follow the flow in arbitrary order to make learners think about the rationale behind the selection. As results of the user evaluation, it was confirmed that the proposed method could give learners opportunities of considering the reasons for the selections, and understanding action guidelines for safe evacuation.
