TSA-Alerie reports [French] that a poster on a conference at the National Library of Algeria has a controversial claim:
La mixité sexuelle à l’école est la cause numéro un de la violence scolaire
which translates to:
Mixed-sex schools are the number one cause of school violence.
The claim is from Smaïl Boulbina, an Algerian sexologist.
I'm very skeptical about that. Is mixed-sex education the largest factor - or even a factor at all - in school violence?
