6. The effectiveness of the comprehensible input is greatly increased when learners have to negotiate for meaning Modification Checks-Do I need to word something differently? Should I paraphrase? Clarification Requests- When a learner does not understand a work being used, they ask for clarification. Confirmation Checks- When a learner reacts to a particular sentence, and utters a word or phrase that may be confusing in their second language. Slowing down the speech.

7. ADVANTAGES Interlocutors may model the correct language form.The learners receive feedback on their production and on grammar Learners receiving more input than the interlocutors When learners stop to clarify something they do not understand, they may have more time to process the input they receive.
