Query: The Collaborative Virtual Affinity Group Model: Principles and Design   The problem addressed in this paper is the challenge arising in enabling
collaborative learning in the context distance education models. While research
has made quantum leaps in the development of both effective collaborative
pedagogical models as well as online learning environments, the research at the
intersection of these two areas has been scarce. This paper presents the design
for a new collaborative virtual model, named Collaborative Virtual Affinity
Group model (CVAG), which is an extension of the successful Affinity Group
Research (ARG) model. The new model provides an integration of the principles
underlying ARG with the traditional principles of virtual learning
environments. The CVAG model is explored in the context of introductory
Computer Science courses|where students are focused on learning the basic
principles of computer programming.
