What is the purpose of a teaching aid?

• A. To replace the teacher
• B. To measure performance
• C. Communicate a concept
• D. To provide entertainment

Answer: (C)

Teaching aids exist to communicate a concept clearly. They present ideas in a form learners can see, hear, or touch, turning abstract or complex information into something concrete and easier to grasp. By illustrating relationships, steps, or processes with charts, diagrams, models, or demonstrations, they help students understand and remember the idea you’re trying to teach. While teaching aids can be engaging, their primary purpose is to clarify and convey the concept, not to replace the teacher, to assess performance, or to entertain.
