The explosion of technology available to schools--and specifically, the ways in which students can misuse technology--has caught many educators off guard. School leaders are now being asked to protect students against potential harmful material they may encounter in cyberspace. The issue of cyberbullying--using technology to harass, intimidate, bully, or terrorize another person--has become a thorny problem for many schools. As a school principal, the author has had to deal with incidents in which an angry parent or a concerned student reports hurtful e-mails, instant messages, or blogs. He points out technology has all but erased the reflection time that once existed between planning a silly prank (or a serious act) and actually carrying it out. He suggests that educators address the issue of cyberbullying head-on, by establishing clear policies for acceptable use of technology and making students aware of the seriousness of such activity. Schools also need to enlist parents as allies in setting firm limits for their children's use of technology. (Contains 8 resources.)
