With the introduction of educational standards by the Conference of Ministers of Education (KMK), a quality development in the German education system is intended. This is only successful if the reform is implemented by teachers and reaches classroom practice. The educational standards define the educational goals as subject-specific competencies that students should possess at a certain point in their educational journey. This establishes the desired outcomes of school education as binding, while simultaneously granting teachers greater freedom and more responsibility in shaping the path to those outcomes. The implementation of the educational standards in school practice is the focus of this study. What actions do teachers take to integrate the educational standards into the planning and design of their lessons?.
