In the proposed system, subject-specific didactics is to be located as a third additional dimension, so that the diagram must be visualised spatially:

In the didactic dimension, the question is how learners acquire linguistic, literary and media skills ("acquisition") and how they should be supported particularly successfully ("mediation"). The diagram makes it clear that this third dimension must always be linked back to the specialised perspective (1st and 2nd dimension).

For you as a student teacher, it is particularly important that the areas of work or areas of competence of German teaching, as they are called in recent literature,are structured very differently.
