This subject is a study of systemic functional linguistic approaches to the study of English grammar and discourse. Topics include: a brief history of the emergence of the theory, and of its particular claims to contribute to language and learning theory, as well as educational theory more generally; notions of three metafunctions in language and of the ways in which each of the three metafunctions is said to contribute to the construction of meaning in language; notions of discourse and of the resources with which language builds different texts, both spoken and written language.
