Principle 2 - Literacy pedagogical content knowledge
“Effective teachers know much more than their subjects, and more than ‘good pedagogy’. They know how students tend to understand (and mis-understand) their subjects; they know how to anticipate and diagnose such misunderstandings; and they know how to deal with them when they arise. This kind of knowledge has been termed ‘pedagogical content knowledge’”
(Grossman & Schoenfield, 2005, p. 205; see also Shulman, 1986).
Literacy pedagogical content knowledge is a vital part of effective content area teachers’ expertise: You cannot be an effective subject teacher without being an effective teacher of the language of that subject.
