What is the teacher's primary role?
 The role of the teacher is to determine the desired behavior and to arrange the external contingencies that will reinforce the desired behavior. ¹ Contingencies: environmental conditions that shape an individual's behavior. There are two types, antecedent (what comes before the behavior) and consequences (what comes after the behavior).²
