“Any curriculum will be pedagogically ineffective if it consists of a lecturer yammering in front of a blackboard, or a textbook that students highlight with a yellow marker. People understand concepts only when they are forced to think them through, to discuss them with others, and to use them to solve problems. A second impediment to effective teaching is that pupils don’t spontaneously transfer what they learned from one concrete example to others in the same abstract category. Students in a math class who learn how to arrange a marching band into even rows using the principle of a least common multiple are stymied when asked to arrange rows of vegetables in a garden. In the same way, students in a critical thinking course who are taught to discuss the American Revolution from both the British and American perspectives will not make the leap to consider how the Germans viewed World War I.” (Steven Pinker, Enlightenment Now)
