Abstract

The purpose of this study was to investigate the effects of the first-year field test BSCS middle school science program on student understanding of the creative, developmental, testable, and unified nature of science. The experimental group, which was exposed to the BSCS program, and the control group, which was taught using a more traditional middle school science curriculum, were administered a pretest and posttest using the Modified Nature of Scientific Knowledge Scale (MNSKS). Analyses of the results showed that the understanding of students who experienced the BSCS science program decreased significantly in regard to the developmental and testable nature of science. The understanding of students who experienced the control-group science program decreased significantly in regard to the creative nature of science. Analyses of covariance indicated that students in the control group possessed a significantly better understanding of the testable nature of science than did students who used the BSCS science program. Implications of these results are related to the constructivist view of learning, the development of curricula designed to facilitate scientific literacy, and future research endeavors.
