“Learning is the relatively permanent change in a person’s knowledge or behavior
due to experience. This three components: 1) the duration of the change is long-
term rather than short-term; 2) the locus of the change is the content and structure
of knowledge in memory or the behavior of the learner; 3) the cause of the change
is the learner’s experience in the environment rather than fatigue, motivation,
drugs, physical condition or physiologic intervention.”
