Genre analysis examines how language is used in different social and cultural contexts. There are three main approaches discussed in the document: the ESP school, the Sydney school, and the rhetorical genre studies school. The ESP school focuses on describing genres and their structures to inform materials development. The Sydney school analyzes genres using systemic functional linguistics, examining field, tenor, and mode. The rhetorical genre studies school focuses on how genres are acquired, critiqued, and used by students in real contexts. Genre analysis is useful for language pedagogy by helping students understand genres and develop competence in new genres.
