What are the key principles of the Audio lingual method?

1) language learning involves attending to form and structure

2) grammar and vocabulary are taught inductively

3) the students' native language can be used to give instructions when necessary, to help a student to improve his or her pronunciation

4) learned  competence  can correct utterances initiated  only if there is enough time

5) students are rarely corrected when they orally express themselves because the meaning is more important than the form
