Virtual learning environments, often referred to as online learning or e-learning, have proliferated both at the K-12 and the adult levels. Formal virtual learning communities (VLCs) at the K-12 level however, are relatively new phenomena. Traditionally, literature regarding online learning has focused largely on technology and learner-computer interaction. These isolated computer-mediated environments where the need for community and human interaction remains unchanged and unchallenged stand in contrast with face-to-face environments where community has traditionally been created and fostered. The emergence of communities in virtual learning environments provides challenges and opportunities to develop interactive, collaborative communities. This field is growing and expanding rapidly, inviting innovation, enthusiasm and the attention of researchers and practitioners. Associated literature is expanding and the need for further research has been noted (Nippard & Murphy, 2007). While there have been significant contributions to research in this area, the sparseness of literature reveals a need for further investigation. For this review a comprehensive search of the literature was conducted although research on VLCs in higher education is more abundant than research at the k-12 level.
Research on the formative elements of VLC, both formal and informal is extensive, especially as it pertains to the adult population. Sadik (2003) and Downs and Moller (1999) note the need for research to address the younger generation of online learners and specifically the topic of socialization at the high school level. The paucity of literature at the K-12 level is largely attributable to the fact that the field is in the early stages of development and as such, concepts are not clearly defined. Research has suggested that educational and online communities are underdeveloped and in their infancy (Coffman, 2004; Downes,
