David Kolb is an American educational theorist best known for his work on experiential learning. He developed the Kolb's Learning Cycle, which outlines how people learn through experience. This cycle includes four stages: concrete experience, reflective observation, abstract conceptualization, and active experimentation. Kolb's ideas emphasize the importance of hands-on learning and reflection in the educational process. Kolb's theories have influenced various fields, including education, business training, and organizational development. His work encourages educators and trainers to create environments where learners can engage actively with material, fostering deeper understanding and retention. Kolb's contributions continue to shape modern approaches to learning and development.
