Interview data exemplify students' attempts to integrate the concepts of electrochemistry with related knowledge that they had previously constructed or acquired in other classes. The implications for minimizing potential misconceptions center on the difficulties students experience when using more than one model for explaining scientific…

Indicates that measures of reflective reasoning skill are significantly related to initial scientific beliefs about evolution, as well as to gains in declarative knowledge about evolution; however, the same measures are not significantly related to changes in those beliefs. Interrelationships among the study's major variables and their educational…

Summarizes comparisons of self-reported interest by gender and experimental condition for middle school students (n=101) who performed scientific experiments under conditions designed to vary across difficulty levels, social contexts, and scenarios of fantasy to realism. Findings indicate that boys were more attentive to aspects of experimental…

Compares 7 biology faculty members, 9 genetic counselors, and 26 undergraduate students according to both expertise and problem-solving success within the domain of genetics. Findings are consistent with the hypothesis that as expertise is attained, the individual restructures knowledge into a framework based upon the critical dimensions which…

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

Utilized an experimental design structure across 4 scientific contexts which tested 18 boys and 18 girls who were closely matched for ability levels and curriculum background. No gender differences were detected in the scientific contexts of observation, reporting, or planning skills, and there was no differential performance on the use of…

Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…

Fourteen elementary and middle school teachers from an inservice physics course were found to share a common core of strongly held propositions that formed a coherent, but incorrect and contradictory, model of the sequential flow of electrical current. Theoretical and practical implications of these teachers' beliefs with respect to both…

Presents results of intensive clinical interviews with 11 high school chemistry students representing a broad range of achievement levels as selected from 180 students who completed a written test upon completion of an instructional unit on chemical change. Results indicate that students commonly experience difficulties in chemical knowledge,…

Presents race concept as an example of how social issues are underemphasized in college science education. Reviews history of the race concept and reports on current status of the concept in textbooks and among college faculty members. Given specific stipulations, proposes continued use of the race concept for some infrahuman species, while…

Describes a qualitative study that explores students' perceptions of their own learning. Document review, participant observation, and open-ended interviews were used to gather and triangulate data. Factors that were perceived as helpful were woven into a theoretical model. The uses of the model are discussed. (Author/KR)

Describes the achievement of high- and low-reading-ability students in an introductory college biology course after they received and used teacher-provided questions or learned to generate and use their own questions. Discusses the ecological validity or applicability to classroom use of question generation. (KR)

Focuses on the enhancement of chemistry students' skill in problem solving utilizing problem categorization techniques. Indicates that explicit training in categorization skills can lead to higher achievement in complex problem-solving situations but that such achievement may be limited by the lack of linkages between students' conceptual…

Examines the generalizability of selective-attention and academic-studying hypotheses to a modified science chart medium. Describes the questions designed to selectively focus students' attention on specific columns in a modified science chart, with the goal of improving student achievement on a test measuring learning of content contained in…

Discusses students' awareness of science/technology/society (STS) issues, the importance students assign to STS issues, and students' achievement in a genetics unit after infusing STS vignettes into class discussions. Recommendations are made on the use of STS vignettes by science teachers. (KR)
