What are language acquisition theories?(4)

4. Input and Interaction Theories

a. Comprehensible Input (Krashen)

• See Monitor Model above.

b. Interaction Hypothesis (Long)

• Key Idea: Interaction and negotiation of meaning in communication help learners acquire language.
• Implications: Activities that encourage clarification requests and feedback (e.g., role-plays, pair work) promote learning.

c. Output and Feedback

• Learners benefit from producing language (Swain’s Output Hypothesis) and receiving feedback to refine their language use.

d. Input Processing (VanPatten)

• Key Idea: Learners prioritize meaning over form when processing language input.
• Implications: Teachers should design input that encourages learners to focus on grammatical forms in meaningful contexts.
