Behaviorism views knowledge as existing independently of people and acquired through replacing undesirable behaviors with desirable ones, and learning as involving observable changes in behavior. It focuses on how behavior begins with stimulus-response interactions with the environment. A key concept is that the environment learns behaviors, minimizing innate influences, and behaviorism centers on conditioning being observable without considering feelings. In EPP teaching, behaviorism would impact instruction by conditioning students to react and respond appropriately to their environment.
