In a sense, Didactics is the study of how to transform utilitarian disciplinary knowledge into learnable disciplinary knowledge .
... which involves (among other elements)
- mastery of explicit disciplinary knowledge
- strong sense of where learners fall apart
- wide range of responses to student difficulties
- awareness of implicit associations (PCK)
- a willingness to be improvisational
- an attitude of willingness
- vertical and horizontal connections between curriculum
- a responsibility to knowledge and a responsibility to individual students
Within the category of pedagogical content knowledge I include, for the most regularly taught topics in one's subject area, the most useful forms of representation of those ideas, the most powerful analogies, illustrations, examples, explanations, and demonstrations – in a word, the ways of representing and formulating the subject that make it comprehensible to others.
