Single-sex schools are concerned about turning classrooms into single-sex classes. This topic is important because it concerns the development of the country and the education system. There are various arguments as to whether single-sex schools are for or against separating the two sexes from each other. Single-sex schools increase distraction, unequal academic outcomes, and affect social life. First, supporters of the idea of ​​single-sex schools believe they provide a better educational environment. They argue this because the presence of both genders in a classroom creates distraction due to physical and emotional issues. However, the presence of only one gender can also create distraction due to the change in some physical and emotional states of the students. As cited in Boyd (2014), by grouping students of one sex together, the most important elements of true education are lost. Aggression and violence also increased distraction in single-sex classrooms. Aggression and violence have increased recently among boys, with exceptional rates in all-sex schools. In the case of girls, they continue to chat with each other in single-sex classes, but when boys are there, their chatting rate decreases because they are sometimes shy towards the opposite sex. The presence of girls with boys can also limit aggression and violence between them. . As cited in Fergus and Noguera (2010), violence and aggression lead to the worst racist stereotypes. The problem of violence against children can trigger something even more complicated and dangerous such as racism and stereotypes among students. In addition to the competition between the two sexes in educational tasks for...... middle of paper ......er both in real life and in the field of business. Since the two sexes will not be able to work together in the future, what is the benefit of education? Women have entered all fields of work. If the two sexes could not work together, all the education they were taught would be of no use. Finally, it is now clear that single-sex schools are more distracting, have the same academic results (in some cases less) and have some shortcomings in the social lives of students. Therefore, distraction also occurs with one gender, no difference in academic achievement, increases sex segregation, and increases social pressure in the future. So it would be better to either upgrade the education system or forget about the idea of ​​putting students into this kind of schools which do not add anything useful to students but rather destroy their lives in the distant future..
