This paper is a comparative review of four seminal works on communities of practice (Lave and Wenger 1991, Brown and Duguid 1991, Wenger 1998, Wenger, McDermott and Snyder 2002. It is argued that the ambiguities of the terms community and practice are a source of the concept's reusability allowing it to be reappropriated for different purposes, academic and practical. However it is potentially confusing that the works differ so markedly in their conceptualisations of community, learning, power and change, diversity and informality. The three earlier works are underpinned by a common epistemological view, but Lave and Wenger (1991) is often read as primarily about the socialisation of new-comers into knowledge by a form of apprenticeship, while the focus in Brown and Duguid (1991) is, in contrast, on improvising new knowledge in a interstitial group that forms in resistance to management. Wenger (1998) 1 IntroductionThe concept of communities of practice has become popular in several academic fields including organisational studies (particularly the topics of knowledge management and organisational learning) and education. Information scientists interested in knowledge and learning are also using the term (witnessed, for example, by bibliographic reviews in the it is a conceptual lens through which to examine the situated social construction of meaning. At other times it is used to refer to a virtual community or informal group sponsored by an organisation to facilitate knowledge sharing or learning. This paper does not attempt to prescribe one definition, rather it aims to clarify for the reader variations in usage and comment critically on the different conceptions.A particular cause of confusion is significant divergences between three earlier seminal works; one or all of which are cited by almost every author who uses the concept. These are: Having considered the four works, a summary section draws together the discussion foregrounding their differences and particular contributions. The conclusion points to a major distinction between direct and indirect social relations as the foundation of communities.
Lave and Wenger (1991)The dominant reading of Lave and Wenger (1991) has been that it proposes a new approach to understanding learning, including that which takes place in the workplace.This approach focuses on informal and situated social interaction, rather than on a planned mechanistic process of cognitive transmission. Such interaction achieves authentic, motivated learning of what is needed to be known about the complexities of real practice. It is a central proposition that learning is more than simply acquiring knowledge, it is about an identity change. Peripheral participation, active involvement in the practice, is identified as a key process in learning. Table 1 summarises some features of this new account, set against the rejected orthodoxies (as the authors themselves construct them). Referring to a community of practice is not a way to postulate the existence of a new informal grouping...
