Two weeks ago, The Times printed an article about the up-and-coming movement for single-sex education. In the particular situation highlighted, boys and girls attend the same school, but are separated by different classrooms. The article started by relating a couple anecdotal pieces which show the benefits of being able to “tailor to each group.” Michael Napolitano, the boys’ teacher, “speaks to his fifth-grade class […] like a basketball coach.” When teaching his students “how to be a man,” Mr. Napolitano explains, “If I get in the face of a girl, she would just cry […] the boys respond to it, they know it’s part of being a young man.”
