The purpose of this study is threefold. First, to develop and implement an elementary school social studies political science class that aims to cultivate digital citizenship. The second is to verify the effectiveness of the developed lessons based on the children's behavior. The third is to reconstruct the framework of the class structure based on the children's behavior. To achieve these objectives, we developed a sixth-grade elementary school unit entitled "What We Can See from the Sluggish Voter Turnout of Young People" and implemented it in a class.
