Archer et al suggests that one reason for these differences is the conflict between working-class girls' feminine identities and the values and ethos of the school
Some working-class girls adopted loud feminine identities that often led them to be outspoken and independent and assertive, which brought conflict with teachers
Either gaining symbolic capital from their peers by conforming to a hyper-heterosexual feminine identity or gaining educational capital by rejecting their working-class identity and conforming to the school's middle-class notions of a respectable ideal female pupil
