Firstly, mixed-sex schools provide a perfect environment for healthy competition between boys and girls in schools (Sparks, S.D, 15). Thomson also supports this view by arguing that human beings are naturally inclined to compete with the members of the opposite sex (Thomson, n.p.). For this reason, therefore, in co-ed schools, boys will do their best to perform better than girls, and girls will also try very hard to outshine the boys in their academic performance. This fact, therefore, shows that co-ed schools provide an opportunity for healthy completion between boys and girls in school.
