More American schools going single sex

HARTLAND, Wisconsin: Lauren Panos was surprised when she walked into her ninth-grade English class in the fall and saw there were no boys.

Her parents had not told her they had enrolled her in a new all-girls class at Arrowhead High School in Hartland, about 40 kilometers west of Milwaukee, Wisconsin. A semester into classes, Panos is still not sold on the idea. "All the girls there, they can talk out of turn," the 14-year-old said. "We get really off task and it's really annoying."

More public school systems are looking at separating boys and girls, whether for certain classes or by entire schools, after the federal government opened the door last fall. Supporters say splitting students by sex minimizes distractions, helps them learn better and allows boys and girls to explore subjects they may not otherwise take.
