Communities of practice (CoP’s)—much touted and studied as a mechanism for teacher education and professional development—may offer environments for deeper learning and transformation of their participants. This chapter examines more meaningful outcomes possible in community-centered learning— deep learning, changes in professional culture and identity, and participants “finding voice”—outcomes of value not often seen in formal educational and traditional professional development settings. Drawing on qualitative data from participants in a three-year community of writers and literacy educators, this study suggests that CoP’s can be linked not only to development of knowledge and skills, but also to changes in participant beliefs, attitudes, voices, visions, and the identities of practicing educators.
