„When there are classroom disciplinary problems, boys seem to be more disturbed by this than girls are. In fact, the more the average school teacher perceives there are disciplinary issues, the greater the difference in PISA reading scores between girls and boys within schools – favouring girls. Perhaps boys are more affected by deteriorated learning conditions because they are exposed to greater peer pressure than girls. It is also more likely that boys are the students disturbing lessons. Overall, boys seem to be less able than girls to stay focused on their schoolwork when there are disciplinary issues in the school.“
