Social studies education has had a turbulent history as one of the core subjects in the school curriculum. The fundamental content of the social studies curriculum – the study of human enterprise across space and time –however, has always been at the core of educational endeavors. It is generally accepted that the formal introduction of social studies to the school curriculum was instigated by the 1916 report of the National Education Association’s Committee on Social Studies, which emphasized development of citizenship values as a core aim of history and social science education. Earlier commissions of the N.E.A. and American Historical Association heavily influenced the Committee on Social Studies recommendations. The roots of the contemporary social studies curriculum, therefore, can be traced to two distinct curriculum reform efforts: the introduction of academic history into the curriculum and citizenship education. There is widespread agreement that the aim of social studies is citizenship education, that is the preparation of young people so that they possess the knowledge, skills, and values necessary for active participation in society. This apparent consensus, however, has been described as almost meaningless because social studies educators continue to be at odds over curricular content as well as the conception of what it means to be a good citizen. Since its formal introduction into the school, social studies curriculum been the subject of numerous commission and blue-ribbon panel studies, ranging from the sixteen-volume report of the American Historical Association’s Commission on Social Studies in the 1930s to the more recent movement for national curriculum standards. Separate and competing curriculum standards have been published for no less than seven areas of that are part of the social studies curriculum: United States and global history, economics, geography, civics, psychology, and social studies. Social studies curriculum is defined a lack of consensus and has been an ideological battleground with ongoing debates over its nature, purpose, and content. Historically there have been a diverse range of curricular programs that have been a prominent within social studies education at various times, including the life adjustment movement, progressive education, social reconstructionism, and nationalistic history. The debate over the nature, purpose, and content of the social studies curriculum continues today, with competing groups variously arguing for a social issues approach, the disciplinary study of history and geography, or action for social justice as the most appropriate framework for the social studies curriculum.
