What is Networked Knowledge Activity

Personal learning networks (PLNs) are a form of informal professional development in which teachers build and maintain connections to other educators and learning professionals and the resources that will meet their personal continuing education needs. Although PLNs can incorporate face-to-face connections, they typically make heavy use of social networking tools for finding and sharing information and educational innovations. In this chapter, the authors discuss how PLNs have been developed and used by preservice and inservice teachers, discussing the similarities and differences between the two groups along with the progression of PLN development from preservice to inservice teacher experiences. Next the authors discuss the role that PLNs play in helping teachers develop their blended and virtual learning knowledge and skills, along with ideas for how teacher-educators and administrators can provide support for this endeavor.
