As a teacher, I can stop bullying by making my students aware of the effects and the aftermath of it. Especially in the psych part. I will make them realize that bullying is good for nothing and I will educate them on the rules and regulations of the school about the offense. Also, I will make a background check on each one of them and try to understand their situation and maybe befriend them so that they will not force their anger out on students. hope it helps. ;)
