Through conversational interaction, students learn the grammatical and pragmatic conventions for conveying particular communicative intents. They also learn the metacognitive skills of reflecting on their language use. As individuals engage in conversations, they alternate roles as producers and receivers. This shifting in roles enables individuals to take the perspective of the other and to learn the critical skill of constructing discourse so that it can be understood. Speakers engage in monitoring, evaluating, and revising their intended and expressed message in accordance with their listener’s potential and actual understanding.
