The current national priority for systemic approaches to the reform of scie
nce and mathematics education has led to unprecedented interest in research
on the efficacy of science and mathematics teacher preparation programs. I
n response to this priority, a focus on collaborative approaches to educati
onal reform and to research on educational reform resulted in a national co
llaborative research consortium of insitutions of higher education. The con
sortium was formed to investigate the following question about secondary sc
ience teacher education: What are the perceptions, beliefs, and classroom p
erformances of beginning secondary teachers as related to their philosophie
s of teaching and their content pedagogical skills? The research design and
instrumentation yielded detailed descriptions that elicited knowledge and
beliefs held by beginning teachers about science, the nature of teaching an
d learning, and their philosophy of teaching. An analysis of video portfoli
os of beginning teachers provided classroom-based evidence of their perform
ance in both subject matter and pedagogical dimensions of teaching. Among t
he findings from this 3-year exploratory study were that teachers graduated
from their teacher preparation programs with a range of knowledge and beli
efs about: how teachers should interact with subject content and processes,
what teachers should be doing in the classroom. what students should be do
ing in the classroom, philosophies of teaching, and how they perceived them
selves as classroom teachers. Beginning teachers described their practices
as very student-centered, Observations of these teaching practices contrast
ed starkly with teacher beliefs: While teachers professed student-centered
beliefs, they behaved in teacher-centered ways. Undertaking intensive, coll
aborative studies such as the one described in this article, is the beginni
ng of efforts through which the science and mathematics education communiti
es can strive to address the needs of students, teachers, teacher educators
, and other stakeholders working to establish a common vision for excellent
instruction and systemic, long-lasting reform. (C) 1999 John Wiley & Sons,
