This introduction is aimed at students of educational and social work programs. It does not provide a comprehensive overview of sociology, its history, theories, and research findings. Instead, sociological terms and theorems are exemplified in relation to problems and questions relevant to education and social work. The intention is to provide future teachers, educators, and social workers with an engaging entry point into sociological thinking and knowledge. Each contribution clarifies the potential practical value of sociological theories and research for education and social work. "Sociological Basics" is particularly well-suited as a text foundation for lectures and seminars.
