The document discusses the Audio-Lingual Method, an oral-based language teaching approach developed in the 1950s. It uses behavioral psychology principles to teach grammar through repetition and drills. Students learn dialogs, which are used to practice patterns through activities like repetition, question-answer, and substitution drills. The teacher controls the class, and students imitate models. While it was innovative in applying linguistics, critics argue it is mechanistic and ignores other aspects of language.
