The Audio Lingual Method is a language teaching method from the 1940s that was introduced in the US and later spread to other countries like Indonesia in the 1960s. It focuses on teaching speaking skills through repetition drills and behaviorist techniques to help students learn the target language automatically. Teachers present dialogs for students to repeat together and individually. Variations include expansion drills, chain drills, and substitution drills. While it engages students actively, the method does not explain grammar rules and focuses only on speaking practice.
