To learn to drive, you require many component skills, including knowing where the gas and brake pedals are and when to use them, how to steer, when and how to use your mirrors, all while following the rules of the road.
Experienced drivers find it very difficult to think of each component separately, not as a whole. They drive with a level of automaticity, knowing their reflexes will apply each component as needed.
Learning the component skills to achieve mastery is crucial in any classroom discipline. For example, in economics, physics, or chemistry, the application of a formula can be more easily learned if simple calculations like addition and multiplication have first been mastered so that no cognitive overload occurs. Having the component skills in place allows the learner to focus on the larger conceptual problem.
What concept in your discipline is like driving a car? Can you identify the component skills required to master this concept or skill?
