It is impossible to describe all the motivational permutations and combinations that exist in any instructional setting. It is, however, important to recognize a few important principles that relate to motivation. First, all behavior has some motivational antecedent. People do or don't do things for different reasons, and those reasons are their motives. Like it or not, people, including students, are motivated by vanity.
Pride is a form of vanity.
This is probably the worst of all motivators. If people do or don't do something because they fear a consequence, their actual behavior is unpredictable, because it may lead to other undesirable, destructive or anti-social behavior. Teachers should never threaten students as a way of motivating them to learn something. Power is a strong motivator, but has little application in most classrooms. If a person is motivated by power, it means that the person is engaging in some behavior because he wants to cause others to have to choose among alternatives that he sets.
