single sex education or co-education? Indeed, being taught separately, to some extent, can effectively avoid some unnecessary problems. Understandably, at certain ages, students of the opposite sex can be a distraction or even a harm. It is widely acknowledged that sexual harassment happened in school concerns a vast number of parents. Not only can single sex schooling ease this concern, but boosts students’ academic success. In fact, being in a single sex environment, students are more likely to focus on academia instead of their classmates. In addition, in terms of gender identity, schools are able to design courses that are more suitable for each gender, which help students fulfill their potential more easily. However, there are also some clear disadvantages of single sex education. Surrounded with the same sex, students undoubtedly lose many opportunities of co-existing or cooperating with their gender counterpart. As a result, their social skills cannot be acquired, which is detrimental to individual development. Single sex schooling artificially creates an unreal life where there is only one sex, but actually, what society comprises is both male and female. Without the opposite sex being, there is high likelihood that until nearly 30, students finally find a best way to get on well with the opposite gender. Therefore, I believe, going to single sex school decelerates children’s growth.
