The Audio-Lingual Method

The audio-lingual method is used in teaching foreign languages. It also called the Army method. It is based on the behaviorist theory. This approach to language learning is similar to the direct method. Like the direct method, the audio-lingual method advises that students should be taught a language directly, without using the students' native language to explain new words or grammar in the target language. But there are also differences, unlike the direct method, the audio-lingual method does not focus on teaching vocabulary. Rather, the teacher drills students in the use of grammar. The instructor presents the correct model of a sentence and the students have to repeat it. Then the teacher continues by presenting new words for the students to sample in the same structure. In the audio-lingual method, there is no explicit grammar instruction, everything is connected to memorizing.
