The Hochman Program, as it is sometimes called, would not be un­familiar to nuns who taught in Catholic schools circa 1950. Children do not have to “catch” a single thing. They are explicitly taught how to turn ideas into simple sentences, and how to construct complex sentences from simple ones by supplying the answer to three prompts—but, because, and so. They are instructed on how to use appositive clauses to vary the way their sentences begin. Later on, they are taught how to recognize sentence fragments, how to pull the main idea from a paragraph, and how to form a main idea on their own. It is, at least initially, a rigid, unswerving formula. “I prefer recipe,” Hochman says, “but formula? Yes! Okay!”
