It is true that the behavior of pupils has been getting worse these days. There are a variety of possible reasons for this, but steps can definitely be taken to tackle the problem.
I think that three main motives are to blame for the way young people behave at school nowadays. Firstly, there are too many children in some classes. That is, it is difficult to manage large classes. Secondly, most parents are too lenient and spoil their children these days. Large numbers of children are used to getting whatever they want, and they do not accept the requirements of teachers. Finally, bad behavior is due to a lack of structure and discipline. The culprits are their parents and schools in this situation.
Student behavior can certainly be improved. I believe that the change must start in schools. For example, schools need to create a positive working atmosphere. Moreover, teachers must have the power to punish disruptive students and should remove difficult children from lessons, because they have an influence on other children. When students break the rules, their parents should be resolute with their children, and definite rules should be imposed on them. Also, if parents and schools want good behavior from the children, they need to work closely with each other, and parents must support the school rules.
To conclude, schools will continue to face discipline problems unless parents, teachers, and public figures set clear rules and demonstrate the right behavior themselves.
