Abstract
Teacher education throughout the 20th century has consistently been structured across a
persistent divide between subject matter and pedagogy. The prevalent conceptualization and
organization of teachers' learning tends to fragment practice and leave to individual teachers
the challenge of integrating subject matter knowledge and pedagogy in the contexts of their
work. We assume that the integration required to teach is simple and happens in the course of
experience. In fact, however, this does not happen easily, and often does not happen at all. This
paper takes up three problems that we must solve if we are to meet this challenge to prepare
teachers who not only know content, but can make use of it to help all students learn. The first
problem concerns identifying the content knowledge that matters for teaching; the second
regards understanding how such knowledge needs to beheld; and the third centres-on what it
takes to learn to use such knowledge in practice.
