Which of the following laws of learning states that the more an act is practiced, the faster and surer the learning becomes?

The principle that the more an act is practiced, the faster and surer the learning becomes is captured by the law of learning known as Exercise. This law emphasizes the importance of practice in the learning process, indicating that consistent and repeated practice leads to stronger retention of the material and greater proficiency. Essentially, the more one engages in a particular activity or skill, the better and more efficient the learning and performance become. This is why repetitive practice is crucial in fields like firefighting, where skills must be second nature to ensure safety and effectiveness in emergency situations.

The other laws focus on different aspects of learning: Intensity relates to how emotionally charged and engaging the learning experience is, which can enhance retention; Recency highlights that information learned most recently is often recalled more easily; and Primacy indicates that information learned first is generally retained longer. Each of these laws plays a role in the learning process, but Exercise specifically addresses the relationship between practice and the effectiveness of learning, making it the correct choice for this question.
