Identity Formation through Brokering in Scientific Practice

Inspired by recent theorization by Dreier and Lave concerning situated perspectives on learning, I illuminate learning of international graduate students in a science lab in Japan as trajectories of participation in multi-layered activities and various mutually constituted occasions, and as crossing of multiple communities of practice. By doing so, I describe trajectories of participation as unique and multiple ways characteristic of individual participants instead of as a linear process from newcomer to old-timer or from peripheral to full participation in a community of practice. Identity formation is also reformulated as discovering and constituting one’s unique self through crossing multiple communities of practice rather than merely as becoming a member in a community of practice. Further, I show that identity formation may be regarded not merely as adjusting the relationship among multiple communities within individuals, but as the practice of organizing new linkages among communities and of reconstituting communities of practice.
