A panel discussion involves 4 to 8 qualified speakers sitting in front of a large audience to discuss a topic. The chairperson/moderator's role is to introduce the topic and panelists, facilitate discussion between panelists through questions, and involve the audience for questions. An example format includes an introduction by the moderator, statements from panelists on both sides of the issue, a discussion period, and a concluding statement. The success depends on the chairperson keeping the discussion flowing and developing the train of thought.
