Small-group discussions are used to determine participants' understanding of content, reinforce and clarify ideas, apply content to real life, and enhance problem-solving skills. They allow participants to learn from each other and take responsibility for learning. Effective small groups have members who come prepared, cooperate rather than compete, and give all members a chance to participate. Discussions are typically 20 minutes, including introduction, exercise, and summary. The process involves introductions, identifying themes, and groups reporting back to the class. Leaders initiate, facilitate, and summarize while all members give information, ask questions, discuss interpretations, and stay on topic.
