To improve the preparation of future teachers, we must come to underst
and their personal theories about teaching and learning. The purpose o
f this study was to investigate preservice elementary teachers' theori
es about science teaching and learning through their rejections on int
egrated media case-based instruction, and subsequently to reflect upon
and reform our own practice. Students in an elementary science method
s course participated in a series of written and oral reflection tasks
in response to integrated media instruction. Specifically, they respo
nded to a videodisc case of a first grade teacher teaching a conceptua
l change unit about seeds and eggs. Considering their responses to the
reflection tasks, we constructed a profile of these elementary preser
vice teachers. This profile consists of their images of themselves as
future science teachers, the characteristics of their personal theorie
s of teaching and learning, and the sways in which they frame classroo
m problems. Our findings led to reforms in our methods course instruct
ion and have implications for the preparation and continuing education
of elementary science teachers. (C) 1998 John Wiley & Sons, Inc.
