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 something for a reason, and that reason is their motive. 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 not threaten students as a way of getting 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.
