Abstract
Although various educational practices regarding the use of social networking services (SNS) have been reported in school education, incidents involving posts going viral and causing issues, such as information leakage and flaming, continue to occur. In this study, we developed an animated educational material for secondary education aimed at raising awareness of information leakage pathways on SNS, and implemented them in junior high school technology and home economics classes (technology field). The developed material includes a section where viewers, along with the characters, reflect on "why this happened" in response to incidents, and provide a detailed explanation of the causes and preventive measures. Through these case examples, the material encourages viewers to recognize the importance of protecting privacy when posting on SNS. As a result of using this animated material in the classroom, students understood that even private accounts on SNS carry the risk of information leakage, just like regular accounts. The educational effectiveness of the material was demonstrated. Furthermore, the learning objective of "understanding the precautions when transmitting information and recognizing the unintended risks and conveniences of SNS" was successfully achieved.
