Book excerpt: An authoritative reference that discusses the history of sex education and its ramifications in the United States. Community and school officials, parents, and educators often stay to the wee hours of the night at PTA meetings arguing about sex education and sexual behavior among young people. While some groups preach abstinence and attempt to sign as many youngsters as possible to their rosters, it remains a fact that 50 percent of U.S. teenagers, beginning at age 15, are sexually active. Sex, Youth, and Sex Education is a wonderfully crafted resource that gives not only a statistical overview of sexual activity in schools, but also examines sex education, the scourge of sexual violence in schools, and sexuality among selected groups of youngsters. What emerges is a groundbreaking work for educators and students of sociology, psychology, and education. This work brings to light the fascinating—not to mention ubiquitous—world of sexuality among today's youth and its impact on parents, school personnel, policymakers, and society.
