Which learning principle emphasizes the importance of practice in reinforcing knowledge?

The principle that emphasizes the importance of practice in reinforcing knowledge is indeed exercise. This principle is rooted in the idea that active engagement and repetition are critical for solidifying learning. When learners have the opportunity to practice skills or apply knowledge, they reinforce what they have learned, making it more likely that they will remember and utilize that information in the future.

Practice allows learners to engage with the material actively rather than passively absorbing information. This engagement can lead to deeper understanding and retention of the concepts being taught. Exercise facilitates mastery by encouraging learners to repeat actions or concepts, which builds confidence and proficiency over time.

The other principles mentioned focus on different aspects of learning. Recency relates to the idea that information is more easily recalled if it has been learned recently. Intensity refers to how emotionally or physically engaged a learner is in the material, which can affect how well they remember it. Primacy deals with the concept that items learned first are often remembered better, but it doesn't specifically address the role of practice in reinforcing knowledge.
