Which principle states that adults learn best through practice?

The principle that states adults learn best through practice is known as "Exercise." This concept emphasizes the idea that active participation in learning, including hands-on practice and real-world application, is essential for retaining information and developing skills. For adult learners, practical engagement helps to reinforce concepts, allowing them to understand how to apply knowledge in different situations, which is particularly relevant in fields like firefighting where practical skills are crucial.

In contrast, other principles focus on different aspects of learning. Readiness pertains to the individual's willingness and motivation to learn at a given time, which can influence their engagement but does not specifically highlight the need for practice. Effect relates to the idea that behaviors followed by positive outcomes are likely to be repeated, creating a connection between learning and its consequences, but again does not explicitly emphasize practice. Disuse suggests that skills and knowledge can deteriorate if not regularly used, but does not indicate that practice is the primary means of learning effectively. Together, these principles show that while they contribute to adult learning, it is the principle of Exercise that confirms the significance of practice in mastering new skills and knowledge.
