           Demonstrations  are valuable tools for teaching both concrete techniques (skills) and abstract concepts (principles). A good demonstration permits a student to learn by observation, a skill we use innately when learning to talk, walk, and even clap our hands. They can be used to teach techniques like conducting a counseling session, using a computer program, or drawing blood for analysis. They can also be used to help students learn concepts like profit margin in economics, Boyle's law in chemistry, or probability in mathematics.

 During the demonstration, give a simple explanation for each step as you proceed. Observe students throughout to make sure your pace isn't too fast or too slow. Remember to summarize the demonstration or let students summarize it. This can be done either as you proceed through it or immediately afterward. After the demonstration, review key points with the class. If a significant number of students missed or misunderstood any key points, you may need to repeat the demonstration. As a follow-up exercise, have students apply the concept to a new situation so they can generalize their learning. For technique demonstrations, it is often helpful for students to watch the teacher coach a student volunteer through a technique. The teacher's facility with equipment often hides difficulties which are readily observed in unfamiliar hands. Then have students perform the technique on their own to consolidate learning.
