The audiolingual method was developed in the 1950s in response to the need for language teaching during World War 2. It was based on behaviorist theory that saw language learning as habit formation through repetition drills. Lessons focused heavily on oral skills, with listening and repeating dialogs as the core activity. Grammar and vocabulary were taught deductively. Students had little control and the teacher led activities through direct instruction and correction. While it was effective for pronunciation and basic structures, the method was later criticized for its lack of focus on meaning and real-world language use.
