Stahl, Gerry2017-04-152017-04-152011978-0-85729-913-0There are many theories useful for framing CSCW research and they may in principle be irreducible to a single theory. CSCW research explores questions involving numerous distinct—though interacting—phenomena at multiple levels of description. The useful approach may be to clearly distinguish levels such as individual, small-group and community units of analysis, and to differentiate terminology for discussing these different levels. Theory in general has evolved dramatically over the ages, with a trend to extend the unit of cognition beyond the single idea or even the individual mind. Seminal theoretical works influential within CSCW suggest a post-cognitive approach to group cognition as a complement to analyzing cognition of individuals and of communities of practice.enText10.1007/978-0-85729-913-0_11
