To see if the teachers who participated in any of our
secondary science programs, which included separate courses
for chemistry, physics, and biology teachers, improved on either
of these two subscales, two mixed-design analyses of variance
(ANOVA) were used. On the PSTEB subscale, chemistry
teachers showed a significant gain from pre- to post-test, with
the mean pretest score = 54.23 (SD = 5.79) and the overall
post-test score = 56.35 (SD = 5.14) with p < 0.05. On the
STOE subscale, there were no significant gains from pre- to
post-test, with the overall pretest score = 36.53 (SD = 5.35)
and the overall post-test score = 35.71 (SD = 5.79) with p >
0.30. These results are also summarized in Table 6.
