In this study, we clarified how a childminder choice student understood the use of the information appliance for preschool education. Specifically, we performed a cluster analysis based on student responses that we obtained by Silent Dialogue, and analyzed the answers both quantitatively and qualitatively. Based on the results, we considered methods for increasing effectiveness of future practice. In addition, for training subjects such as"preschool education methods," we piloted some concrete practices to consider the best approaches for teaching. Finally, the results of this study are discussed and future problems are described.
