Learning In A Constellation of Interconnected Practices: Canon or Dissonance?
研究了中型建筑公司中工程师、现场工头和总承包商三个实践社区对事故原因的不同解释，发现学习通过比较不同视角实现，这种比较既产生秩序也产生紧张和失调。
In this paper we argue that the learning of safety in a constellation of communities of practice is mediated by comparison among the perspectives of the world embraced by the co‐participants in the production of this practice. Our discussion is based on two empirical research projects in which we investigated the accounts of the causes of accidents provided by the members of three different communities of practice (engineers, site foremen and main contractors), in a medium sized building firm. In the paper we suggest that comparison among perspectives is made possible by a discursive practice targeted on the alignment of elements both mental and material, within mutually accountable discursive positions. These alignments are provisional and unstable, they produce tensions, discontinuities and incoherence (cacophony) just as much as they produce order and negotiated meanings (consonance).
