The Time article said more and more schools are taking action to stop bullying. Some teach kids how to talk to, or ignore, bullies. One puts bystanders, in addition to the bullies, in after-school mediation, on the theory that bullies don't perform unless there's an audience. Some of these programs have had concrete results, reducing the numbers of fights and raising students' grades. The important thing is that schools take bullying seriously.
Parents are key ingredients.
They need to help the schools in teaching kids how to respond to bullying and impressing upon kids that teasing and harassing are wrong. And parents need to be involved in their children's lives, asking questions and listening. A crackdown on bullying won't end school violence any more than it would end truancy. But improving the culture of our schools will help improve the culture of our society.
