Behaviorism can be used to help elicit positive behaviors or responses in students, such as by using reinforcement. Teachers with a behavioral approach often use "skill and drill" exercises to reinforce correct responses through consistent repetition, for instance. Other ways reinforcement-based behaviorism can be used in education include praising students for getting the right answer and providing prizes for those who do well. Using tests to measure performance enables teachers to measure observable behaviors and is, therefore, another behavioral approach.
