The document discusses research on second language acquisition and provides guidance for ALTs and JTEs on effective team teaching.
It summarizes that input is crucial for language learning, but the input must be comprehensible to learners. Teachers should use techniques like elaboration, gestures, visual aids, and interaction to help make input comprehensible while retaining linguistic complexity. Simplification may improve understanding but not support learning. The document also recommends providing feedback to increase learners' awareness of language forms. Overall, it emphasizes the importance of comprehensible input through adjusted teacher speech, elaboration, and feedback to facilitate both meaning and form in the language learning process.
