                                    Answer: A - The summarizer, note-taker, gatekeeper, facilitator and evaluator are all examples of roles that students may take during a class discussion. Other roles include someone to pick out “quotable quotes” and a question generator. Each of these roles involves active participation within the discussion. Discussion is a powerful tool which promotes student engagement, the activation of prior knowledge, and making connections,  as well as  assisting the teacher in making formative assessments of individual students.
