From the moment students start elementary school all the way through college, they are taught concepts mainly through verbal instruction that teachers expect will later be applied in the real world. However, in school, teachers gauge levels of learning and understanding by conducting tests. By the time students leave school, learning is equated with listening to lectures that are followed by tests. This approach, however, doesnt translate well in the workplace. As observed by Malcolm Gladwell in his 2005 book, Blink: The Power of Thinking Without Thinking, We learn by example and by direct experience because there are real limits to the adequacy of verbal instruction.
