The implementation of "teaching by sex" does have many advantages: from the physiological characteristics, there are differences in intellectual expertise between male and female students. For example, during the university period, there are mostly boys in science and engineering, and most girls in arts and sciences, so it is reasonable to train differently; From the perspective of personality characteristics, women pay attention to cultivating fashionable women and modern women, while men pay attention to emphasizing masculinity, especially in adolescence, so separate cultivation is more conducive to the development of their respective personalities; From the perspective of learning, the establishment of girls' schools and boys' schools can provide students with a relatively simple environment, because there is less interference from the opposite sex, so children can concentrate on their studies. Single-sex schools will form a single-sex communication environment, which will affect the interpersonal communication ability of the opposite sex to a certain extent and increase the difficulty for students to adapt to society.
Therefore, in the process of "teaching students in accordance with their aptitude", schools should increase students' opportunities to contact all kinds of people in society through various forms such as voluntary service and social practice, so as to avoid the school becoming a closed "country of boys" and "country of girls"; Parents should not blindly follow the trend when choosing, but should fully respect their children, pay attention to individual and gender differences, and make choices according to their personality and interests. Not all children are suitable for this kind of education.
For young students, healthy psychology and sound personality are more important than high marks in exam-oriented education, and students' mental health and personality defects cannot be paid for getting high marks.
