The school participates in maintaining a categorical asymmetrical system of the sexes. The students are, after all, girls and boys. This article examines the differences between the sexes in physical and sports education, more specifically, the interactions between teaching staff and students. It includes two studies. The first study, done through video observations, attempts to verify whether or not boys are favoured in these interactions, as has been shown in previous studies. In the second study, a questionnaire reveals the students’ degree of satisfaction with the support they receive from the teaching staff. From an objective point of view, the interactions favour the boys, but from a subjective point of view, the girls do not see it that way. This poses the problem of the interiorization of sexual stereotypes.
