An instructional model for national citizenship, global citizenship, and sustainable development education was developed. Four lesson plans in the elementary 5thgrade social studies were suggested to show the practice of the instructional model. Three outcomes are reported. First, identity as a citizen of a nation, global citizenship, communications are interrelated. National citizenship and communications in the network society can result in a stronger vision of one’s global citizenship. This is especially the case when the wellbeing and happiness of people in neighboring countries who live across the national boundary are viewed within the domain of community- economy- ecology. Each prepares citizens through knowledge and skills that enable them to empathize, criticize constructively, and live together sustainably. The educational methods recommended to attain global citizenship perspectives are critical thinking, comparative studies, and teaching controversial issues. Those methods tend to result in a commitment to guarantee of non-domination freedom and tolerance of others. Second, discussions regarding sustainable development focused largely on deliberative engagement as a teaching method. Issues discussed were: speculative banking and its regulation; medical treatment and education as value goods; the steps necessary for households and businesses to attain sustainability; and environmental justice and social equity. The educational methods recommended to live together sustainably are planning and practice for grassroots democratic communities’ solidarity by applying back-casting strategy and systematic thinking. Thirdly, social studies classrooms intent on to enhance national citizenship, global citizenship, and sustainable development have a five step task. They, should emphasize comparison and critique→ discussion→ empathy→ planning and lastly the engagement of learners in content critical to ecological multiple citizenship.
