“So if there’s anything else on your desk right now, please put that inside your desk.” He mimics what he wants the students to do with a neat underhand pitch. A few students in the front put papers away. “Just like you’re doing, thank you very much,” Zimmerli says, pointing to one of them. Another desk emerges neat; Zimmerli targets it. “Thank you, sir.” “I appreciate it,” he says, pointing to another. By the time he points to one last student — “Nice . . . nice” — the headphones are gone, the binder has clicked shut and everyone is paying attention.
Lemov switched off the video. “Imagine if his first direction had been, ‘Please get your things out for class,’ ” he said. 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.
