This document discusses adult learning and how adult learners learn best. It defines adult learners as typically ages 25 and older who bring life experiences and established beliefs to learning. Adult learning theory suggests adults learn best in problem-based and collaborative environments. Characteristics of adult learners are that they are self-directed, goal-oriented, and want learning to be relevant. Adult learners learn best when their experiences are valued, learning is active and fills immediate needs, and when new material relates to their existing knowledge.
