Online single-sex education

There's been a growing trend in recent years of single-sex, public education...now a couple of all-girls private schools are taking single-sex education somewhere else: online.

For now, the online collaboration will allow the four participating schools -- Holton-Arms, Harpeth Hall in Nashville, Westover School in Middlebury, Conn., and Laurel School in Shaker Heights, Ohio -- to offer classes that would not have generated enough student interest or teacher support in any one school. When the classes open to the public a year later, the educators hope that students around the world -- including homeschoolers and girls at coed schools -- will be able to take part in a version of the girls' school experience. And they want to prove that single-sex online education works. They can't find anyone who has done anything similar.
