As teacher educators, the authors have observed that knowledge alone does not lead to the kinds of thoughtful teaching they strive for.The authors address what is necessary, beyond traditional forms of professional knowledge, to support the development of thoughtful teachers who are responsive to students and situations. The authors provide four perspectives, each drawn from areas in which the authors conduct their research, and suggest a need to move beyond knowledge in teacher education. Their aim is to explore questions about preparing thoughtful teachers and to challenge others to do the same.
