This paper, published last fall, approaches the subject of learning community from the usual sources, producing a list of features most people will find familiar: shared purpose, boundaries, rules and policies, interaction, and trust. Some of these are elements I would identify (not altogether positively) with groups, which would lead me to wonder whether they are equally valued by community members. This study compares student and instructor valuations of different aspects of community participation. There's a lot of crossover, but it's worth nothing that studetns wanted instructors to model community participation, while instructors thought it was more important to "design and facilitate activities." (p.s. it would be really nice if JOLT had an RSS feed so I could spot these when they come out, not six months later).
