Systemic functional linguistics (SFL), a meaning-based theory of language, has been used throughout the world as a discourse analytic approach and, more recently, as a framework for implementing pedagogy in the classroom. SFL has much to offer teachers as a pedagogical approach. The integration of SFL into teacher education and continuing professional learning has been shown to have a positive impact on developing teachers’ knowledge about language, their ability to instruct students by focusing on language and literacy development, and their focus on critical components of language for diverse learners. SFL theory does not provide teacher educators with a developed curriculum for implementation; therefore, the ways in which it has been used across teacher education have varied depending on teachers’ level of instruction (elementary, secondary, or tertiary), familiarity with SFL concepts, and preservice or in-service status. There is no “one-size-fits-all” approach to SFL inclusion in teacher education, but some principles derived from SFL in teacher education literature may enable teacher educators to consider how this theory of language and pedagogical framework can be used in teacher education programs.
