1) The document discusses the pros and cons of using educational blogs (edublogs) in the classroom. It notes that edublogs can help with collaboration but also present safety issues like cyberbullying. 2) Cyberbullying is defined as using technology to harass or threaten others. It is effective because the internet allows unsupervised bullying in front of a large audience. Victims of cyberbullying may experience depression or thoughts of suicide. 3) To address cyberbullying, schools should educate students and have clear policies, while parents should monitor their children's online activities and communicate with them. Overall the benefits of edublogs outweigh the risks if proper safety measures are taken.
