B.F. Skinner developed the concept of operant conditioning, which is a method of learning through reinforcement or punishment of behaviors. Through operant conditioning, associations are made between behaviors and their consequences. Skinner believed behavior should be studied objectively by focusing on external causes rather than internal thoughts. Operant conditioning is commonly applied in classrooms, where desirable behaviors are positively reinforced through rewards like praise, points, or stickers, while undesirable behaviors may be punished through consequences like yelling or confiscating phones. Teachers can use reinforcement to encourage positive student behaviors and establish better behavioral patterns.
