A lot of countries have schools that focus only on the males or females. What are the advantages and disadvantages of unisexual schools?

(Sample 1)
Imagine being asked to spend twelve or so years of years of your life in a society that consisted only of members of your own sex, how would you react? Unless there was something definitely wrong with you, you wouldn't be too happy about it, to say the least. But the fact is that segregated¹ schools shoot up very rapidly around the world, furthermore, so many parents choose to impose such abnormal conditions on their children- conditions which they themselves wouldn't put up with for one minute!

Many sociologists and educationalists present their views on this issue from both sides. Those advocates of segregated schools argue that children from segregated schools have greater achievements academically. Socially in athletic² and have greater self-confidence. Further, there are many more practical advantages in segregated schools such as administration. Adolescent problems can be dealt with better and more easily. Lastly in many countries, the most famous schools are segregated. It is a wonderful proof of their worth.

On the other side, those advocates of co-education point out that any discussion of this topic is bound to question the aims of education. One of the chief aims of education is equip future citizens with all they require to take their places in adult society which is made up of men and women. When segregated, boys and girls are made to feel that they are a race apart. Rivalry³ between the sexes is fostered. Anyone entering adult society after years of segregation⁴ can only be in for a shock. Segregated schools sometimes provide the right condition for sexual deviation⁵ and make children lack of healthy attitude to life that co-education encourages.

To sum up, every coin has double sides but from my point of view, I believe that though segregated schools have successfully existed for centuries it is about time somebody exploded that hoary⁷ old myth about segregated schools being the better place for your children.

Boy schools and girl schools shoot up very rapidly both in foreign countries and at home. In China, girl schools have enjoyed a very long history since one hundred years ago. Many sociologists and educationalists present their views on this issue from different angles. In this essay, I will zero in on the advantages and disadvantages of the controversial phenomenon.    

Some parents prefer to send their children to boy schools or girl schools in the hope that their children can concentrate on study and acquire adequate knowledge and skills because unisexual schools can make out appropriate curriculum and courses for students according to their sexual characteristics. In some girl schools, students have a wider choice of courses such as dancing, music, embroidery⁸ and drawing, which can cultivate their feminine elegance⁹ and charm.

Furthermore, students can devote themselves fully⁶ to their study and will not be distracted. Campus love affairs are very common in the current society under the influence of media. Boy schools and girl schools can eradicate¹⁰ contact between different sexes and purify the campus environment.    

Of course, some experts point out that boy schools and girl schools are not beneficial to the adolescent development of students. They believe that boys or girls are likely to develop their abilities and stimulate¹¹ their imagination when they are studying with the opposite sexes. Besides, students can cultivate their interpersonal skills. Some other people think that separating boys from girls can cause some psychological problems to youngsters. Meanwhile, this separation affects social progress and lead to sexism. Investigation¹² shows that graduates from unisexual schools are not aware how to get along with their colleagues in their career.      

To sum up, everything has double folds. Unisexual schools are of no exception. From my point of view, I think the existence of unisexual schools meets the need of some parents. But it is definitely not a paradise for their children.
