Abstract
While phenomena such as filter bubbles and echo chambers have been attracting attention as negative aspects of personalization, there have been few cases of incorporating them into Japanese elementary education. In this study, we developed lessons where elementary school students come up with mitigation measures for the problems of filter bubbles and echo chambers through discussion based on the benefits of personalization. The lessons were implemented within the unit on the information society in the social studies curriculum for fifth-grade elementary students. Thirty students participated in the first lesson and 29 in the second. Based on the 28 students' comments, worksheets, and reflections during the lessons, it was observed that they understood the benefits of personalization and the problems of filter bubbles and echo chambers, and came up with mitigation measures. Furthermore, the analysis of the questionnaire revealed that one week after the lessons, there was an improvement in the scores of the sub-scales related to objectivity and inquisitiveness in the students' critical thinking attitudes, compared to before the lessons.
