Academic teacher development is an educational meeting place for academics already practising the art of teaching. Yet, it is in courses for this development that academics are supposed to be taught how to teach and how to improve their teaching skills. In my article I propose a new conceptual methodological framework for teaching teachers how to teach – Didactic Reasoning. Its foundation can be traced to pragmatist philosophy and interfaith dialogue in theology. The key aspect of Didactic Reasoning is to make university teachers better teachers by the development of a didactic voice and the courage to try this voice in teaching activities. This is done through intersubjective meetings between academics to develop a respect for the ‘teaching-other’ in their colleagues and through the use of practice-focused themed conversations led by teacher educators.
