For a long time now, proponents of single-sex schooling have argued that boys and girls differ in brain functioning, interests, stress responsiveness and that they cannot be taught effectively in the same classroom. However, there is no well-designed research showing that single-sex education improves students’ academic performance. Scientists agree there is much more overlap than difference between boys and girls in their brains. Learning is best accomplished when the delivery method matches the subject matter. It is not single-sex education that is producing positive results with students but rather it is the motivation of the teacher and the resources that are available.
Even if enrollment were purely optional, the mere existence of segregated classes would lead to increase sexist stereotyping and prejudice. Classroom assignment based on gender teaches children that males and females have different types of intellects, and reinforces sexism in schools and the culture at large. Research on peer relations indicates that children who interact mostly with the same-gender peers develop increasingly narrow skill sets and interests. Developmental research finds better mental health outcomes among children who develop a mix of traditionally masculine and feminine skills and interests.
