Should boys and girls be educated in separate classrooms?

Yesterday, I read a statement in TOEFL material that said boys and girls should be educated in separate classrooms using different teaching techniques.

Here is my opinion: 

I must say that I do not support boys and girls being taught in separate classrooms. I believe this method will (can/may is better in this situation, as will implies this change will happen) cause many disadvantages as the boys and girls won't have any interactions.

School is not only a place to learn science but also social life. Most of a student's life will be spent in school. So if boys and girls are separated, their social learning will (may/can) be disturbed. In the future, they may act awkwardly towards each other since they are not used to socializing. 

The ability to interact with other sexes is needed, when the child is as young as possible to ensure boys and girls see each others (another word is needed here) respectively. For example, knowing girls when they are younger will teach boys how to be good men in the future, and what kind of demeanors (This isn't the right word - use 'behaviour') is needed to treat them correctly. So, if boys and girls are separated, they will grow without understanding each other.

Also, different teaching techniques are not needed to differentiate (this word doesnt make any sense to your arguement - replace with something like 'teach') boys and girls. The only thing which is different between them is just their sex. Their learning teachniques are similar to each other since they grow up in similar environments. Different teaching techniques may make them feel one sex is superior to the other.

Finally, it can be said that separating boys and girls in different classrooms should not be applied in schools. 
 
Good luck
