dvanced social information exchange is required in modern society. Therefore, two increasingly important goals in school education are enabling students to acquire practical information utilization skills and teaching students how to appropriately use the Internet. In particular, there is a strong need in today's society for the ability to use social networking services (SNS) such as LINE, Twitter, and Facebook. However, many risks related to the use of SNS have been reported, and a recent increase in problematic behaviors of students due to inappropriate Internet usage, such as cyberbullying and Internet dependence, has become a significant problem in Japan. As a result, the Japanese government has requested that schools improve education about rules and manners for using the Internet. Providing such education about the Internet, especially education that changes the awareness, attitudes, and behaviors of children when using SNS, is an important and necessary role of schools today.
Experiencing actual behaviors is an effective way to learn correct attitudes and develop a better sense of awareness. Therefore, we developed an SNS system that allows students to actually experience using an SNS and realize the risks and dangers of using such platforms. We developed two types of computer systems to assist with this education. The first system is for classrooms without facilities for Internet access, and the second is for classrooms with Internet access. The first system is implemented with a laptop computer. This system is compact and easily portable, and it includes a built-in laptop computer server function as well as a wireless LAN access point function. The second system was built on a cloud computer, and is used via the Internet.
In this study, we implemented a practical lesson for a special-needs school that teaches students how to safely use SNS. The results show that simulated experiences of posting content via SNS using our system caused students to have an increased interest in learning and helped them to better understand the appropriate awareness, attitudes, and behaviors for using SNS. Furthermore, according to a survey conducted approximately one month after the experiment, the students retained the knowledge on how to handle personal information and minimize the dangers of using SNS that they learned during the lesson, suggesting a long-term effect from this approach.
