Epistemic criteria are the standards used to evaluate scientific products (e.g., models, evidence, arguments). In this study, we analyzed epistemic criteria for good models generated by 324 middle-school students. After evaluating a range of scientific models, but before extensive instruction or experience with model-based reasoning practices,…

The purpose of this pragmatic action research study was to explore our re-conceptualization efforts in preparing pre-service teachers to guide the inquiry process with formative assessment and subsequently use the understandings to improve our teacher preparation program. The process was guided by two questions: to what extent did course…

There exists a general consensus in the science education literature around the goal of enhancing learners' views of nature of science (NOS). An extensive body of research in the field has highlighted the effectiveness of explicit NOS instructional approaches in improving learners' NOS views. Emerging research has suggested that engaging learners…

Integrated quantitatively the collective research dealing with the effects of the Intermediate Science Curriculum Study (ISCS) on student performance and attitude. The weighted mean effect size was 0.09, indicating that the performance of ISCS students was 0.09 standard deviations about the performance of students in traditional science courses.…

Investigates cumulative effects of SCIS in terms of students' attitudes. Hypothesized and supported is that students exposed to the complete SCIS program would show a greater degree of positive attitude toward science, experimenting, and the scientist than would those not exposed to SCIS. Results indicating sex differences in attitudes are…

Questions Whether first-grade student participation in selected experimental activities from the BSCS-ESSP enhances skills in listening as measured by the Cooperative Primary Series Listening Test (CPSLT). (CS)

Explores the use of free sort methodology to compare BSCS student and teacher understanding of the BSCS conceptual framework. Results support the idea that teachers who have better understanding of the BSCS conceptual framework, as shown by their sort patterns, may impart this understanding more effectively to students. (CS)

Reports that teachers exhibit a stable degree of persistence in utilizing selected elementary and secondary NSF science curricula in the western United States. Differences between teachers trained in the NSF curricula and a control sample indicate that elementary workshop participants tended to utilize NSF-sponsored curricula longer than did…

Developed and validated anecdotal and data-summary persuasive communications and tested their effect on preservice teachers' attitudes toward supplementing traditional, textbook-based science programs with either Science-A Process Approach or the Science Curriculum Improvement Study. Results show that anecdotal nature communications were more…

Compares effects of the Human Sciences Program (BSCS) and conventional programs on attitudes of eighth-grade students. Variables include course, gender and school (including teacher). Evaluation of results from responses on a semantic differential questionnaire indicate very positive response to the Human Sciences Program. (CS)

Describes changes and effects of the Israeli paper-and-pencil matriculation examination in biology since first analysis in 1972. The examination has been significant for implementing an inquiry-oriented high school biology program based on the Biological Sciences Curriculum Study. Implications for upgrading science education are discussed.…

A Biological Sciences Curriculum Study (BSCS) inquiry approach for university general biology laboratory was tested against a well-established commercial program judged to be highly directive. The BSCS was found to be more effective in learning biology laboratory concepts than the commercial program as measured by a laboratory concepts test.…

Science curriculum evaluation studies (1963-1978) were examined to assess impact of innovative curricula compared with traditional curricula on student learning outcomes. Results suggest students in secondary school science courses scored moderately better than students in traditional courses on innovative and neutral tests and negligibly lower on…

Supported by this experimental study was the hypothesis that science process skills of premedical and predental students could be improved by a semester-long course modeled after the AAAS Science - A Process Approach curriculum. Recommendations are made regarding the inclusion of science process skills in college science courses. (CS)

This study examined whether a relationship existed between field-dependence-independence and scientific attitudes of sixth-grade students in SCIS. Findings indicated that such a relationship was not statistically significant. (Author/DS)
