This document discusses the history and principles of communicative language teaching (CLT). It describes how methods have shifted over time from the grammar-translation method to more recent approaches focused on meaningful communication. The audiolingual method emphasized repetition and habit formation but failed to develop students' communicative abilities. CLT emerged due to theories of language as rule-governed creativity and a view of language's primary function as communication. CLT organizes instruction around real-life tasks and uses the target language to maximize engagement and language use.
