Using tools such as the social-network-creation site Ning, teachers can easily develop their own networks, Mosea says. "It is better to create your own," he argues. "If a teacher creates his or her own network, students will post as if their teacher is watching them, and they'll tend to be more safe.
"You can build social networks around the curriculum," Mosea adds, "so you can use them as a teaching resource or another tool." An online social network is another tool -- but it's a tool with an advantage: It wasn't just imposed by teachers; the students have chosen it.
