Andragogy, self-directed learning and transformational learning are some adult learning theories. Andragogy is the art of helping adults learn, self-directed learning is when individuals take responsibility for their own learning, and transformational learning is learning that alters a person's concept of themselves and the world.
Created by Mathew Knowles, the theory of factors involved in adult learning occurs when people have their own self concepts and direct their own learning, use personal life experiences as a resource for learning and are ready to learn when changing social roles. As of 2015, 70 percent of adult learning is self directed. Self-directed learning usually takes place outside of the classroom and occurs when the learner determines his own needs, identifies resources and sets goals with a plan of implementing them.
