Central to Lemov’s argument is a belief that students can’t learn unless the teacher succeeds in capturing their attention and getting them to follow instructions. Educators refer to this art, sometimes derisively, as “classroom management.” The romantic objection to emphasizing it is that a class too focused on rules and order will only replicate the power structure; a more common view is that classroom management is essential but somewhat boring and certainly less interesting than creating lesson plans. While some education schools offer courses in classroom management, they often address only abstract ideas, like the importance of writing up systems of rules, rather than the rules themselves. Other education schools do not teach the subject at all. Lemov’s view is that getting students to pay attention is not only crucial but also a skill as specialized, intricate and learnable as playing guitar.

Zimmerli got the students to pay attention not because of some inborn charisma, Lemov explained, but simply by being direct and specific. Children often fail to follow directions because they really don’t know what they are supposed to do.

All Lemov’s techniques depend on his close reading of the students’ point of view, which he is constantly imagining. In Boston, he declared himself on a personal quest to eliminate the saying of “shh” in classrooms, citing what he called “the fundamental ambiguity of ‘shh.’ Are you asking the kids not to talk, or are you asking kids to talk more quietly?” A teacher’s control, he said repeatedly, should be “an exercise in purpose, not in power.” So there is Warm/Strict, technique No. 45, in which a correction comes with a smile and an explanation for its cause — “Sweetheart, we don’t do that in this classroom because it keeps us from making the most of our learning time.”

Ball began to theorize that while teaching math obviously required subject knowledge, the knowledge seemed to be something distinct from what she had learned in math class. It’s one thing to know that 307 minus 168 equals 139; it is another thing to be able understand why a third grader might think that 261 is the right answer. Mathematicians need to understand a problem only for themselves; math teachers need both to know the math and to know how 30 different minds might understand (or misunderstand) it...At the heart of M.K.T., she thought, was an ability to step outside of your own head. “Teaching depends on what other people think,” Ball told me, “not what you think.”
