This self-study of collaboration examines the lived experiences of a univer
sity researcher and a classroom teacher who shared the work of teaching 6th
grade science. Sharing teaching involved planning, enacting, assessing, an
d reflecting upon instruction, and became the context for telling stories o
f collaboration. I interpreted these stories using models of social identit
y that employ performance metaphors in the construction/deconstruction of m
ultiple identities. The analysis uncovered several tensions in building a c
ollaborative relationship: a) The tension created by my assumption of multi
ple roles including new reacher, researcher, and collaborator; b) the tensi
on between my desired role of collaborator and the role of professor ascrib
ed to me by the classroom reacher; and c) the tension of an outsider search
ing for a comfort zone in an established classroom community. The meanings
of collaboration that emerged from this study have implications for others
who embark upon university/school partnerships. (C) 2000 John Wiley & Sons,
