The document discusses three major learning theories - behaviorism, cognitivism, and humanism - and their implications for teaching. Behaviorism focuses on observable behaviors and uses concepts like conditioning and reinforcement. Cognitivism examines internal mental processes like memory, paying attention to how information is encoded, stored, and retrieved. Humanism advocates a student-centered approach and emphasizes self-actualization, freedom to learn, and creating a safe environment. Teachers can apply aspects of each theory, such as using behavioral objectives, understanding memory processes, and facilitating self-directed learning.
