In a comparison study that looked at the results of 76 students using BSCS Biology: A Human Approach and 49 students using another biology program, BSCS found there was an overall improvement in mean post-test scores. When a more detailed study was conducted to examine the relationship between the teachers’ fidelity of use of the program and student learning, more interesting results emerged.

BSCS conducted a research study in Denver Public Schools during the school year 2006-2007 in conjunction with the first year of implementation of BSCS Biology: A Human Approach. This pilot study investigated the links between fidelity of implementation, teacher self-efficacy, and student learning. Research found that, overall, students made significant gains on an independent pretest to posttest measure of an ecology chapter, regardless of teachers’ fidelity of program implementation.

The American Institute of Biological Sciences (AIBS) conducted a review of ten textbooks that were used in yearlong courses in the biological sciences in secondary schools. The goal was to provide information to those in school districts who choose instructional materials to make informed decisions that help teachers provide all students with standards-based learning environments for biological literacy. Two BSCS programs were reviewed in the AIBS publication – BSCS Biology: A Human Approach and BSCS Biology: An Ecological Approach.

In this article, the authors describe results from two field-test studies conducted by BSCS, both of which indicate a strong relationship between fidelity of curriculum implementation and student learning gains. In 1995, BSCS studied the implementation of BSCS Biology: A Human Approach and found that student gains, pretest to posttest, were significantly higher when teachers taught the program with fidelity than when teachers taught the program with low fidelity. In 2002, BSCS studied the implementation of BSCS Science: An Inquiry Approach and found that student gains, pretest to posttest, were significantly higher when teachers taught the program with medium to high fidelity.
