Even though in theoretical arguments about the role of mass schooling in modern society there is equal weight given to schools’ potential to develop human capital and citizenship skills, in empirical study there is far more work on the former than the latter.

Sociological theory and methods of inquiry have been crucial in developing this line of research (Sorensen & Morgan, 2000).
