Learning across Communities of Practice: An Examination of Multidisciplinary Work
研究不同实践社群成员（如癌症专家）在多学科团队中如何通过讨论、承认其他观点和挑战假设来学习协作，强调边界过程对拓宽意义的作用。
Communities of practice (CoPs) have been identified as important sites of learning. Novices learn from masters whilst participating in situated practice and becoming more central members of the community. Empirical studies highlight the difficulty of learning across CoPs, although few studies specifically examine how learning develops in such a multidisciplinary context. We examine the processes of learning occurring when members of different CoPs, in this case various cancer specialists, are required to meet together as a formally constituted multidisciplinary team, and to establish multidisciplinary collaboration as a basis for decision making and action. Our paper highlights that while learning in CoPs develops through repetition, gaining legitimacy and achieving mastery, learning across CoPs in multidisciplinary contexts emphasizes key boundary processes to negotiate and broaden meaning. As such, multidisciplinary collaboration is not so much to learn from each others' talk, but to learn to talk in this new arena. We identify three practices which facilitate learning across CoPs: organizing discussions, acknowledging other perspectives and challenging assumptions. We also discuss the boundary processes which are promoted through brokers and the use of boundary objects in facilitating multidisciplinary work.
