Operant conditioning, developed by B.F. Skinner, emphasizes learning through rewards and punishments, illustrating that behaviors followed by positive reinforcement are likely to be repeated while those followed by punishment are weakened. Key concepts include positive and negative reinforcements, distinctions between respondent and operant behaviors, and various reinforcement schedules. The theory has significant educational implications, advocating for motivation and positive reinforcement over punishment to foster desirable behaviors and learning outcomes.
