Which principle of learning implies that an individual will learn more from the real thing than from a substitute?

The principle that states an individual will learn more from the real thing than from a substitute is known as the principle of intensity. This principle emphasizes the importance of engaging, vivid experiences in the learning process. When learners interact with genuine situations, materials, or experiences, they tend to have a deeper understanding and retention of the information.

Using real objects, scenarios, or authentic contexts allows learners to make connections to their existing knowledge and engage their senses, leading to more robust learning outcomes. For instance, conducting an experiment rather than just reading about one enables the learner to experience the concepts directly, fostering a more profound grasp of the subject matter.

The other principles, while relevant to learning, focus on different aspects: the principle of effect pertains to the emotional response to learning, the principle of primacy relates to the tendency to better remember information presented first, and the principle of readiness emphasizes the importance of students being prepared and motivated to learn. Each of these principles has its significance, but none directly address the value of direct experience over substitutes in the way the principle of intensity does.
