The Audio-Lingual Method is a method of foreign language teaching that was introduced in the United States in the 1940s. It emphasizes speaking and listening before reading and writing, uses dialogues as the main form of presentation, and drills as the main technique. The teacher presents a dialogue and students repeat it together and individually. Variation drills are used, including repetition, replacement, and transformation drills. While it aims to create speaking habits, the Audio-Lingual Method is teacher-centered and lacks explanation of grammar rules.
