Demonstration is a public showing that emphasizes the merits and usefulness of a product, concept, or process. It involves speaking to an audience while showing how something works. Effective demonstration establishes rapport, avoids assuming prior knowledge, focuses on key points, and follows a step-by-step plan. It should be well-prepared, keep students engaged, summarize key ideas, and evaluate student learning to achieve its objectives. Demonstration promotes peer learning, critical thinking, and better outcomes than individual work.
