The terrorist attacks of September 11, 2001, brought a stark reality to social studies classrooms throughout the United States. Globalism and the expansion of world trade relations created optimism about enhanced cultural understanding, peace, and economic prosperity. However, it is clear that globalization also has a dark side. Suddenly globalization has become associated with a "clash of civilizations," and its critics find justification for their contention that the real results of economic interdependence have been inequity, cultural alienation, and political fragmentation. The debate over globalization has led to renewed emphasis on the study of global politics in the social studies curriculum. In this article, the authors describe four concepts related to globalization--interdependence, informationalism, neoliberal economic philosophy, and holistic analysis--and present an overview of Internet sites that can help social studies teachers gain a deeper understanding of the multidimensional nature of international affairs since the end of the cold war.
