Traditional concepts of civic education in the United States and the expanding horizons curriculum scope and sequence are challenged by globalization and transnationality because new understandings of citizenship are emerging. In our conceptual analysis, we reconceptualize social studies curriculum for childhood to meet these changes. First, we propose a theoretical framework synthesizing literature in the areas of multicultural, global, and democratic education. Second, we propose opening curriculum and research to the voices of students, especially transnational students. Such reconceptualizations have important implications for a social studies curriculum for childhood that is socially just and responsive to the changing sizes, types, and qualities of the communities with which students engage.
