This document discusses three main perspectives (paradigms) on learning: behaviorism, cognitivism, and constructivism. Behaviorism emphasizes that learning is a change in behavior and that the environment shapes behavior through reinforcement. Cognitivism views learning as a mental process and focuses on what occurs in the brain, such as how information is organized into schemas. Constructivism posits that learning involves creating one's own understanding through making sense of experiences and that project-based and inquiry-based learning support this approach.
