I (Clare) am writing with my research team a paper about literacy teacher educators who use a constructivist approach. I found this amazing quote from Virginia Richardson which seems to succinctly sum up the challenge. I thought I would share it with you because it helped clarify some of the issues.
Constructivist teaching as a theory or practice, however, has only received attention for approximately one decade. Current interest and writing in constructivist teaching leave many issues unresolved. These issues relate, in part, to the difficulty in translating a theory of learning into a theory or practice of teaching, a conversion that has always been difficult and less than satisfactory. However, the nature of constructivism as an individual or group meaning-making process renders this conversion remarkably demanding (Richardson, 2003, p. 1623).
