No one can claim to be practically skilled in a science while despising theory without merely revealing themselves to be an ignoramus in their field. This study book is also shaped by the conviction that theoretical knowledge is not in opposition to practical competencies, but rather a prerequisite for them. It is aimed at students and educators in social science, particularly in educational science programs, and presents fundamental perspectives on socialization through texts by Durkheim, Parsons, Mead, Habermas, and Bourdieu. Detailed explanations and exercises related to these authors' texts facilitate reading and simultaneously uncover the significance of their theories for the analysis of educational practice.
