Behaviorism is a theory of learning based on conditioning. There are two types of conditioning: classical and operant. Classical conditioning pairs a stimulus with a response, while operant conditioning uses rewards and punishments to modify behavior. B.F. Skinner developed operant conditioning using a Skinner box to reward rats' behaviors. In the classroom, teachers can apply behaviorism by rewarding good behaviors and punishing bad ones to shape student learning. The document provides examples of how a teacher's classroom may incorporate behaviorism through reinforcement and consequences.
