Which description best fits the concept of a teaching aid?

• A. It replaces teachers entirely
• B. It only records data for later review
• C. It communicates a concept
• D. It eliminates practice errors

Answer: (C)

Teaching aids communicate a concept to learners by presenting information in a clear, perceptible form. They support instruction by illustrating or demonstrating ideas so students can grasp them more readily, rather than replacing the teacher or serving only as data-collection tools. While they can help reduce errors by making mechanics or ideas easier to see, they don’t guarantee that all mistakes disappear. In golf coaching, for example, a video showing proper swing path or alignment sticks illustrating the target line are teaching aids that convey the concept clearly and aid understanding.
