A panel discussion involves 4-8 qualified speakers sitting in front of a large audience to discuss a topic, led by a moderator. The moderator introduces the speakers and topic, and facilitates discussion. Panel discussions allow experts to present different opinions on a topic and can provoke better discussion if properly planned. However, experts may not be good speakers and personalities could overshadow the content. Role playing involves students spontaneously acting out a situation to experience it emotionally and develop insight. It is used to practice real-life scenarios and develop skills like communication. Role playing encourages independent thinking and involvement. Some advantages are developing new skills and sensitivity, while disadvantages include being time consuming and requiring careful planning.
