This document discusses the audio-lingual method, a language teaching technique developed in the 1940s-50s. It is based on behaviorist theory that language learning occurs through habit formation from repetition and reinforcement. The method uses drills, memorization, and practice of dialogs and sentences without translation. While it produced quick results, critics argue it ignores context and natural language acquisition. Research showed other methods led to better long-term communicative ability. The method declined in the 1960s-70s as understanding of language and learning improved.
