The purpose of this article is to provide an overview of three theoretical frameworks that appear related to teachers who manifest an ethic of care. An in-depth review of related literature develops Noddings' theory of the ethic of care, focusing on defining care in teaching. It is further supported with theories of moral development, the theory of relational knowing, and the role of self in teacher development. This article provides support for considering and incorporating the development of an ethic of care as fundamental pedagogical content knowledge to be included in pre-service teacher education.
