In addition to this, teachers also need to recognize how different students learn and adapt activities that have a wide variety and interest that can satisfy all students, teachers can consider the theories for learning when teaching primary school children. Behavioral learning theory is mainly used for behavior management, Pavlov (1927) is one of the theorists behind this behaviorist theory. He discovered that ringing a bell could induce salivation in dogs even when no food was present, if the dog was trained to associate the bell with food.
