Bullying

Preble High School here in Green Bay has several student led groups that work on preventing bullying. The Gay Straight Alliance helps foster acceptance of sexuality. The leadership group helps demote the existence of bullying of any kind. If students feel they are being bullied they should talk to their teacher or another staff. Bullying is not tolerated. Cyber-bullying is addressed in the class Challenges of the 21st Century. Cyber-bullying is also addressed in newsletters. Here's an example of  a Preble newsletter that addresses bullying and cyber-bullying http://www.greenbayprebleonline.com/assets/newsletters/2010%20December%20new%20nl.pdf
Many of the teachers talk about it with the students as well. This it the most effective way to get the message across to students.
