The main tasks of teaching are to stimulate and support learning and development processes. These should be aimed at ensuring equal opportunities, enabling all children and adolescents to engage in informed, self-determined, creative, and socially responsible actions within a societal context. Based on this vision and drawing on important insights from didactic approaches and findings from empirical teaching research, the authors develop the concept of action- and development-oriented teaching. This is understood as a problem- and case-based engagement with tasks that are significant for children and adolescents and can be addressed in a differentiated manner according to varying learning prerequisites. The book offers a variety of suggestions for current or future activities.
