I need to know whether there is any technical term to refer to the specific knowledge and ability which is used to transfer the knowledge itself; i.e. I am looking for a (perhaps) technical term that is used as a reference to a successful teacher assuming the fact that they are quite knowledgeable to teach a particular subject matter, however they have the knowledge of knowledge transfer too. Is there any technical or non-technical term to refer to this ability? I mean knowledge of knowledge transfer in English?
The former 'knowledge' in "knowledge of knowledge transfer", is a sort of art. In other words, the art of knowledge transfer, which in turn, can be called a knowledge itself.
I needed to discover whether there is any particular term as a reference to this art or not! I think there should be something in language teaching terminology, since I heard something once; I cannot remember what that was though!
