Many decades ago, parents were convinced that children should have a separate place of education according to their gender. In the past, it was a prevalent decision because, in compliance with the ideology of the past, girls and boys had different priorities. However, with the advantage of a new society, co-educational schools were created, and now parents are debating whether to send their children to single-sex or mixed-sex schools. I am convinced that non-gender-segregated schools offer children more advantages in terms of preparation for later life and mutual appreciation.
