Cyber bullying has been a problem for a very long-time.Due to the development of our technology today,cyber-bullying has become one of the most difficult issues  to resolve on our society.Since cyber-bulling issues are more likely happento schools,social networking,and mobile phones;Teachers,principals,and parents are responsible to monitor ,prevent,and punish cyber-bullying.Meanwhile many staff feel unprepared and unwilling to be prosecutors and judges because they do not want to be used by something done which might seem right to them but not to others,especially to parents ho are responsible for the child''s well being.Student and Teachers should always have conversation about daily basis.Although teachers can't preach kindness to students;but they can teach students how to kind to one another .Teachers needs to structure learning activities in which children can learn to view individual differences as unique source of streght.For example,a lawsuit was filled against a high school about bullying in upstate New York; a gay teenager used the Mohawk Central School District,saying school officials had not protect him.The district said it would increase staff training to prevent harrasment.It is very important that every student,not just the few that sign up for special projects or after school activities,but students ho are involved in any various activities in school should attend meetings about teaching students ho to respect each other.This will help teachers prevent cyber-bullying in school by drawing students together.People have to understand that some children bully because they have emotional and developmental problems because they come from abusive families.Teachers have to understand that this is only because students require their help.
