The document discusses three language teaching methods:
1) The Audio-Lingual Method emphasizes listening and speaking before reading and writing through drills and imitation. It aims for communicative competence but lacks grammar explanation.
2) Total Physical Response uses actions and gestures to accompany language. Both teacher and students act out commands to learn vocabulary and structures.
3) The Silent Way teaches independently through visual clues instead of direct instruction. The teacher monitors students and encourages oral responses using Cuisenaire sticks to introduce new concepts.
