I am not going to recall any study or any proof of my claims, as the research institutes that conduct these tests are very biased towards certain groups, becoming ingratiate towards them. Therefore, I do not think that it is viable to actually put these pieces of information forward. But what I will do is present my ideas that stem from experience. I assure you, you will find different research finding in different countries.
To begin with, I believe in a mixed learning system, primarily because it helps boys and girls compete with each other. Although the notion of being "carried away" does come into play, I believe that people have to learn to cope with these things, or else they will have to get to a totally new system when working in an office or a multinational company. So yes, do believe that a mixed educational system. It helps to normalize the two sexes with each other, learn to co-ordinate with each other, compete with each other, and get used to a society where men are tolerate and aware of a woman's problems and vice versa.
Now, I believe the success of this system solely depends on the culture, if you were to impose a segregated culture in the middle east, people would be more or less accepting, because their society and social functions are segregated with respect to gender. In Canada, a boy will be often assigned a girl, whom he has to work with, and eventually they learn the importance of co-ordination and they also learn to respect each other's differences. So implementing a segregated educational system, will be difficult and often what a very minorty want. Because their culture is shaped to be mixed.
Now, to come back to the fear of adultery, the evident fact is that, we cannot stop if, we can discourage, and to a great extent, prevent it, but we cannot stop it. But, in segregating an education system, seldom this leads to the idea of homosexuality developing, as seldom in many countries. What we need to do is enforce a stringent rule, that girls have to keep their distance with boys and vice versa. And often, as I have come to see, that this makes both boys and girls act very different in a mixed society, often girls will act absolutely out of control, and boys, sometimes worse. Because the holding back of this leads to such a build-up that people just go nuts! I have seen this happen, unfortunately.
So yes, you may think of benefits, a more focused class, you need to see the drawbacks, that lead to the two halves of society have little experience with the other, little appreciation with other, and most importantly, low chances of a co-ordinated success where both men and women have to work together to solve a problem.
