The growing use of social media by students and adults is impacting schools. A recent Pew study found that 73% of teens use social-networking sites to connect with others. Social media includes blogs, wikis, and podcasts as well as sites such as MySpace, Facebook, and Linkedin. While such sites promote connection with others, their use has created issues impacting schools. Students often don't understand the openness of such sites and frequently share potentially damaging or dangerous personal information, engage in electronic aggression because of the belief that their identity is masked by the anonymity of the Internet, join inappropriate or dangerous online communities or expose themselves to a predator. While the potential dangers are real, schools have begun to recognize the potential of social media to positively impact instruction. The sites can be used to exchange curricular material or to engage students in discussion of class work. Many schools also use social networking sites to communicate with families and community. It is a way to promote their school and share information about the success of students and faculty. (Contains 31 online resources.)
