Disruptive school students having a negative influence on others. should we grouped them and teach?

The phenomenon that a few disruptive school students can have a negative influence on the the whole class is a common problem. Many people have proposed that such students should be grouped them together and taught separately.

['should be taught together', right. it was wrong in the title, though okay here, so have a look at this sentence and the title and see why does one work while the other doesn't]

Personally, i think we shouldn't do that in as much as it will limit the scope of their communication and can make things get worse.
The disobedient or (the) weak students could feel that they were discriminated against, and for the disobedient ones would further develop their disruptive characteristics, and for the weak students would further develop their inferiority complex regarding their ability to learn.
The disobedient and noisy students are still childish and are easily led by temporary thought to do wrong things that they don't intend to. Therefore, the school and the family should be in contact frequently to learn and see more clearly their studying habits and personal situation at home.
Either the disobedient or [either doesn't go with 'and', it goes with 'or'] the weak also can become better more faster and more easily when they correspondend with their friends who have the good behaviors and studying habits. [you can say 'the good behaviors and studying habits they desire/they should have/could have', because to use the word 'the', you must have a specific thing that there is only one of. You can see that it works if you take 'the' out altogether, without making the item specific.]
