Malcolm Knowles was an American educator who coined the term "andragogy" to refer to adult learning. Andragogy assumes that adults learn differently than children in several ways: adults see themselves as self-directed in their learning, adults draw on their life experiences to aid their learning, adults are ready to learn things they need to know to cope with real-life situations, adults are problem-centered rather than content-focused in their learning, and adults are internally motivated to learn. Knowles outlined four principles of andragogy: involving adults in planning their instruction, using experience as the basis for learning, focusing on learning with immediate relevance, and taking a problem-centered approach.
