Teaching in urban schools, with their problems of violence, lack of resourc
es, and inadequate funding, is difficult. It is even more difficult to lear
n to teach in urban schools. Yet learning in those locations where one will
subsequently be working has been shown to be the best preparation for teac
hing. In this article we propose coteaching as a viable model for teacher p
reparation and the professional development of urban science teachers. Cote
aching-working at the elbow of someone else-allows new teachers to experien
ce appropriate and timely action by providing them with shared experiences
that become the topic of their professional conversations with other coteac
hers (including peers, the cooperating teacher, university supervisors, and
high school students), This article also includes an ethnography describin
g the experiences of a new teacher who had been assigned to an urban high s
chool as field experience, during which she enacted a curriculum that was c
ulturally relevant to her African American students, acknowledged their min
ority status with respect to science, and enabled them to pursue the school
district standards. Even though coteaching enables learning to teach and c
urricula reform, we raise doubts about whether our approaches to teacher ed
ucation and enacting science curricula are hegemonic and oppressive to the
students we seek to emancipate through education. (C) 2001 John Wiley Sons,
