Single-sex education refers to the practice of educating students in separate classes or schools based on their gender. This approach can be found in various educational settings, including public schools, private institutions, and charter schools. Proponents argue that it allows for tailored teaching methods that cater to the specific learning styles of boys and girls. Critics of single-sex education raise concerns about potential gender stereotypes and the lack of social interaction between genders. Research on its effectiveness is mixed, with some studies suggesting benefits in academic performance, while others indicate no significant difference compared to coeducational environments.
