Didactic Transposition Circle: A Proposal for Complementing an Essential Tool of ATD

The present article offers a complemented version of the model of the theory of didactic transposition, named ‘the didactic transposition circle’ (DTC). The main modification is that a transposition sub-process from learned knowledge to scholarly knowledge was inserted into the original unidirectional model, complementing it into a circular one. Preliminary elements of the rationale for the introduction and for the application of the new model is presented, after a brief but detailed literature review on the original model.
