The teacher understands how children learn and develop, and provides learning opportunities that support their intellectual, social, and personal development. In my opinion, the purpose of extrinsic motivation in school is to give students a goal to reach and achieve.
Students enjoy being rewarded for their performance in school.
Nevertheless, I do agree with Kohn's proposition that extrinsic motivation is ineffective in producing long-lasting learning. Extrinsic motivation has its flaws because it ranks and grades student's progress, which may become discouraging. This can become extremely dispiriting. Also, giving students F's when they are not doing well in class can make the student believe that they are a failure. I still remember classmates in high school bragging on how low their grades were on their report card.
