5月にあるNordic ISCAR 2010のEngeström企画シンポでディスカッサントやることになった．多層的な活動を横断する実践に埋め込まれた「複雑な概念」，境界を横断する学習に関係があるテーマ．
CONCEPT FORMATION IN PRACTICE Organizer: Yrjö Engeström, University of Helsinki
Complex concepts are embodied, embedded and distributed in and across human activity systems equipped with multi-layered and multi-modal representational infrastructures or instrumentalities. Complex concepts are inherently polyvalent, debated, incomplete, and often ‘loose’. Different stakeholders produce partial versions of the concept. Thus, the formation and change of complex concepts involves confrontation and contestation as well negotiation and blending. Complex concepts are future-oriented. They are loaded with affects, hopes, fears, values, and collective intentions of future development and change. Complex concepts evolve through cycles of stabilization and destabilization. The formation of complex concepts is not just internalization of culturally given concepts but above all externalization, generation of culturally new prototypes, ideas and practices, which also need to be internalized in use. The symposium aims at delineating concept formation in practice as an important area of research and practical interventions within cultural-historical activity theory. Complementary research designs and conceptual resources are presented and discussed as potential ways to progress in this area. In the syposium, the three contributors analyze concrete cases of concept formation in practice. Yrjö Engeström (University of Helsinki) discusses an intervention project aimed at expansive concept formation in the home care of the elderly in the city of Helsinki. Sten Ludvigsen (University of Oslo) analyzes the concepts used by teams of professionals in the estimation of software systems. Jaakko Virkkunen and Leila Lintula (University of Helsinki) analyze concept formation as an industry-wide, historical process, focusing on the formation of a new concept for the activity of Finnish polytechnics. Naoki Ueno (Tokyo City University, Japan) will serve as discussant of the three papers.
