The purpose of this paper is to re-evaluate citizens' activities such as pollution studies in the 1960s and 1970s, and citizens' joint learning activities of natural science by The Association for the Geological Collaboration in Japan ("Chi-dan-Ken") that were active throughout Japan in the same period, from the analytical perspective of science communication introduced in Japan after the 2000s. Through this process, we will reevaluate science communication and social education in Japan. Through this process, we will explore the interface between science communication and social education, and reconsider science communication as social education.
As a conclusion of this paper, social education activities of science, including natural science and social science, are science communication activities, There are two sides of the same coin. In other words, science communication activities can be considered as social education activities, and at the same time, it is significant to conduct science learning activities in a broad sense in social education as science communication. In other words, it is essential to discuss the science learning activities of local residents who are tackling contemporary issues from the perspectives of both science communication and social education.
