A teacher provides only a written definition for a difficult concept and gives no example. What would be a better method?

Correct answer: Add examples, visuals, and discussion with the definition

The governing concept is selecting complementary communication methods for the receiver's understanding. A difficult abstract idea becomes easier when a definition is supported by a concrete example, a suitable visual, and discussion or questions. These methods address different ways of learning and allow clarification. Option C is correct. Making the definition harder, enlarging letters alone, or deleting the definition does not explain the concept more effectively.
