Why are action verbs used in the preparation of performance objectives?

Tasks consist of a single action verb and an object. The verb may represent the cognitive,
affective, psychomotor, or interpersonal domain. A task should have a definite beginning point
and should be independent of other tasks. For example, the task understand sauce making is
meaningless. What does understand mean? Where does it start? Similarly, the chef supervisor
would have a difficult time observing the task appreciate in the importance of good sauce
making. Following are examples of action verbs for each level of learning:
