According to a January 2007 survey by the Pew Internet & American Life Project, 55 percent of teens (ages 12 to 17) report having created a personal profile online, and an equal number regularly use social networking sites such as MySpace or Facebook. Of those, 91 percent use the sites to stay in touch with friends they see frequently. With all that screen time, students are acutely attuned to--and sometimes more comfortable with--living in the digital world. Thus, it follows that their learning should become more digital, say proponents of social networking in education. In this article, the author describes how educators, who have recognized how much social networking engages and informs students, are taking an if-you-can't-beat-'em-join-'em attitude. Many of these educators are now creating their own sites as learning tools that foster collaboration among students, teachers, and parents.
