HARTLAND, Wis. (AP) — 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. Panos still isn't sold on the idea.

"All the girls there, they can talk out of turn," the 14-year-old said. "We are bored of tasks and it's really upsetting."

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

"Boys just make a bigger trouble in the class," Panos' classmate, Alyson Douglas, 15, said “I likes not worrying about boys causing disruptions.”

Presently, nationwide, at least 253 public schools offer single-sex classes and 51 schools are entirely single sex, according to the National Association for Single Sex Public Education. In1995, just three public schools offered single-sex classes.

Critics of same-sex classrooms argue that proven methods of improving education should be carried out instead of one that divides boys and girls.

"Too many schools feel they can carry out a social experiment with students' education with really the weakest of theories," said Emily Martin, deputy director of the American Civil Liberties Union's Women's Rights Project.

Single-sex schools are an "illusionary(错觉的) silver bullet," said Lisa Maatz, director of public policy and government relations for the American Association of University Women. They distract(分散) from real problems and do not offer proven solutions such as lower class sizes and enough funding, she said.

"I would suggest that for many of our kids and families, especially in Milwaukee, it's a question of choice," Spence said. "We have a series of choices in Milwaukee and I just think this should be one additional choice."
