The purpose of this study was to develop a teaching material in which students choose agricultural chemicals that adapt to different condition, and we investigated how this teaching material affected the construction of risk perception. The students were able to understand the knowledge and skills of agricultural chemicals through this teaching material. However, the understanding of how to use agricultural chemicals before the harvest season was insufficient. In the risk perception of agricultural chemicals, the students realized that it is necessary to select appropriate agricultural chemicals from economic, environmental, and social perspectives, which led to a multifaceted understanding of agricultural chemicals. This suggests that this teaching material contributed to the risk perception of agricultural chemicals; in particular, the activity of selecting one from multiple prepared options was produced based on the viewpoint or idea of ??technology and the concept of technology. It was thought that this would lead to the development of the judgment ability to select the most suitable option considering productivity, environmental load, safety, et al.
