Prosecutors say Forbes repeatedly had sex with a year-old boy at the school. Sax points out specific instances where keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. He addresses a host of issues, including discipline, learning, risk taking, aggression, sex, and drugs, and shows how boys and girls react in predictable ways to different situations. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. An avalanche of research over the past twenty years has shown that sex differences are more significant and profound than anybody guessed. In some cases they happened during school hours when there were other students just on the other side of the door," said Galveston County Assistant District Attorney Adam Poole. Kevin Forbes says the evidence shown at trial wasn't enough to convict his wife. Despite the view of many educators and experts on child-rearing that sex differences should be ignored or overcome, parents and teachers would do better to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy. Forbes' husband insists his wife did not have sex with the boy. Poole says the pair clearly had conversations that stretched beyond the relationship that should exist between teacher and student. Stephanie Forbes was found guilty last Friday of having an inappropriate relationship with a student and of sexual assault of a child. So if you ask a troubled adolescent boy to tell you what his feelings are, he often literally cannot say.
