Compared to civics education, a political socialization perspective on global citizenship education has dominated the study of citizenry formation with much of its theoretical ideas and causal reasoning borrowed from child psychology and cultural anthropology. Fully articulated by the end of the 1950s in the U.S, political socialization envisioned influence from many socialization agents, such as family, peer group, and mass media, on youth’s civic values, attitudes, and knowledge; and, although the school is listed among these, it is more or less lost over the next few decades of American research (Hyman 1959; Merelman, 1969, 1971, 1972).
