In September, one month after the Taliban took over Afghanistan, the new government allowed boys back into school—but not girls. Ever since then, female teachers and girls older than 12 have been waiting at home to hear if, and when, they can get back in the classroom.

Somehow, there’s a glimmer of hope. A set of rebellious—and very brave—teachers have banded together to secretly teach girls. Thanks to computers and the Internet, this feat is a bit easier than it was when the Taliban ruled in the 1990s. Started by the charity Learn Afghanistan, these undercover online classes will allow 100 Afghan girls ages 12 and up to learn science, technology, engineering, and math.
