Quality of teaching in the tension between individualization and standardization. The art of didactic craftsmanship and its reflection lies in engaging students in learning. A didactics that is conceived from the perspective of learners inevitably encounters the diversity of learning prerequisites, developmental stages, and learning conditions. This diversity presents a challenge for all educators. The book provides insights into a competence-oriented teaching approach that navigates between the poles of standardization and individualization. It describes, step by step, the journey from recognizing learners in their diversity through lesson planning with a focus on competence orientation to practical implementation, including tasks, methods, learning arrangements, social forms, and performance assessment. This is the author's conviction.
