My school is somewhat similar to the school in Exercise 3 in terms of having a reward system for good behavior and a punishment system for rule violations. However, the specific rewards and punishments may differ. In my opinion, the most effective rewards are verbal praise and recognition, as they provide students with immediate positive reinforcement. On the other hand, the most effective punishment is likely to be a loss of privileges, such as recess or extracurricular activities, as it directly impacts the student's daily routine and activities. Ultimately, a combination of both rewards and punishments is necessary in maintaining a well-behaved school community.
