In a chilly classroom in the southern Afghan province of Kandahar, the birthplace of the Taliban movement, teenage girls pore over Islamic texts as the disembodied voice of a male scholar emanates from a loud speaker.
Pupils take turns to email questions to the scholar on the class laptop at the Taalum-ul-Islam Girls' Madrasa, or religious school, where male teachers are forbidden from hearing the voices of female students in person.
