This document discusses differences in learning across developmental stages from childhood to adulthood. It notes that factors like age and developmental levels impact learning in different ways as individuals progress through stages of growth. Specifically, it outlines characteristics of young learners, noting they learn best through hands-on interaction, exploration, imagination and short attention spans. The document also summarizes Malcolm Knowles' theory of andragogy, or adult learning, noting adults are more self-directed, draw on life experiences, are problem-centered and motivated internally to immediately apply new learning. Finally, it contrasts adult learners with adolescents and children, stating adults have clearer objectives, need involvement in choosing how to learn, and come to class with diverse backgrounds.
