We talked a lot about the ills of rewards, when used in conjunction with behavior management in the classroom. Some say that rewards can be effective tools for correcting inappropriate behavior. Some say that rewards could actually become a punishment in the long run (encouraging students to do something for the sake of rewards and not because they are internally motivated to do so). Some others say that rewards, when used sparingly and thoughtfully, can be an effective tool for behavior management.
What is your view in this matter? Why do you say so? Your answer must be substantiated with a real-life example (preferably classroom example).
