Why Don't Students Like School? ranges over a variety of subjects in pursuit of two goals that are straightforward but far from simple: to tell you how your students' minds work and to clarify how to use that knowledge to be a better teacher.
Note
1 * There actually were three other criteria for inclusion: (i) using versus ignoring a principle had to have a big impact on student learning; (ii) there had to be an enormous amount of data, not just a few studies, to support the principle; and (iii) the principle had to suggest classroom applications that teachers might not already know. The first edition offered nine principles; in this second edition I've added a tenth chapter on technology and education.
1 Why Don't Students Like School?
Question: Most of the teachers I know entered the profession because they loved school as children. They want to help their students feel the same excitement and passion for learning that they felt.
They are understandably dejected when they find that some of their pupils don't like school much, and that they, the teachers, have trouble inspiring them. Why is it difficult to make school enjoyable for students?
Answer: Contrary to popular belief, the brain is not designed for thinking. It's designed to save you from having to think, because the brain is actually not very good at thinking. Thinking is slow and unreliable. Nevertheless, people enjoy mental work if it is successful. People like to solve problems but not to work on unsolvable problems. If schoolwork is always just a bit too difficult (or too easy) for a student, it should be no surprise that she doesn't like school much. The cognitive principle that guides this chapter is:
People are naturally curious, but we are not naturally good thinkers; unless the cognitive conditions are right, we will avoid thinking.
The implication of this principle is that teachers should reconsider how they encourage their students to think, in order to maximize the likelihood that students will get the pleasurable rush that comes from successful thought.
The Mind Is Not Designed for Thinking
What is the essence of being human? What sets us apart from other species? Many people would answer that it is our ability to reason – birds fly, fish swim, and humans think. (By thinking I mean solving problems, reasoning, reading something complex, or doing any mental work that requires some effort.) Shakespeare extolled our cognitive ability in Hamlet: “What a piece of work is man! How noble in reason!” Some three hundred years later Henry Ford more cynically observed, “Thinking is the hardest work there is, which is the probable reason why so few people engage in it”* (Figure 1.1).
FIGURE 1.1: Kanye West is one the most successful and respected songwriters and performers, as well as a highly successful businessman. But he has said, “I actually don't like thinking. I think people think I like to think a lot. And I don't. I do not like to think at all.”1

Both Shakespeare and Ford had a point. Humans are good at certain types of reasoning, particularly in comparison to other animals, but we exercise those abilities infrequently. A cognitive scientist would add another observation: Humans don't think very often because our brains are designed not for thought but for the avoidance of thought.
Your brain has many capabilities, and thinking is not the one it does best. Your brain also supports the ability to see and to move, for example, and these functions operate much more efficiently and reliably than your ability to think. It's no accident that most of your brain's real estate is devoted to these activities. The extra brain power is needed because seeing is actually more difficult than playing chess or solving calculus problems.
You can appreciate the power of your visual system by comparing human abilities to those of computers. When it comes to math, science, and other traditional “thinking” tasks, machines beat people, no contest. Calculators that can perform simple calculations faster and more accurately than any human have been cheaply available for 40 years. With $50 you can buy chess software that can defeat more than 99% of the world's population. But we're still struggling to get a computer to drive a truck as well as a human. That's because computers can't see, especially not in complex, ever-changing environments like the one you face every time you drive. And in fact, the self-driving vehicles in development typically use radar, lasers, and other sensors to supplement information from visible light.
Robots are similarly limited in how they move. Humans are excellent at configuring our bodies for tasks, even if the configuration is unusual, such as when you twist your torso and contort your arm in an effort to dust behind books on a shelf. Robots are not very good at figuring out novel ways to move and are most useful in repetitive work such as spray painting automotive parts or moving pallets or boxes at an Amazon fulfillment center – jobs in which the objects to be grasped and the locations to move them are predictable. Tasks that you take for granted – for example, walking on a rocky shore where the footing is uncertain – are much more difficult than playing top-level chess (Figure 1.2).

Compared to your ability to see and move, thinking is slow, effortful, and uncertain. To get a feel for why I say this, try solving this problem:
In an empty room are a candle, some matches, and a box of tacks. The goal is to have the lit candle about 5 ft off the ground. You've tried melting some of the wax on the bottom of the candle and sticking it to the wall, but that wasn't effective. How can you get the lit candle 5 ft off the ground without having to hold it there?2
Twenty minutes is the usual maximum time allowed, and few people are able to solve it by then, although once you hear the answer you will realize it's not especially tricky. You dump the tacks out of the box, tack the box to the wall, and use it as a platform for the candle.
This problem illustrates three properties of thinking. First, thinking is slow. Your visual system instantly takes in a complex
