The document discusses a study on using social networking to promote learning in college classrooms. It describes how three courses at two Taiwanese universities integrated a private social network called Ning to supplement face-to-face instruction. A survey of 44 students found that the social features of sharing information and interacting online enhanced their learning experiences and sense of classroom community. By facilitating informal sharing and discussion, social media shows potential to support communities of practice in higher education when used as a supplemental learning tool.
