Proposes the concept of cultural validity as a form of test validity in science assessment. Contends that current approaches to handling student diversity in assessment are limited. Discusses ways in which adopting cultural validity as a criterion for test validity makes it necessary to shift assessment paradigms and adopt new procedures for…

Reports a study of the relationship between nonverbal analytical perception and performance on a standardized science achievement test among premedical and predental students. Hypothesized that students with above-average scores on the Embedded Figures Test would attain higher than average achievement scores, as compared with students with…

Examined field dependence/independence in the context of other variables for its value in providing a clearer understanding of the problem-solving process. Results from 150 students indicate that field independent students significantly out-performed field dependent students on the six problems administered. (JN)

Investigates the influence of five cognitive variables on high school students' performance on balancing chemical equations by inspection. Reports that reasoning, restructuring, and disembedding variables could be a single variable, and that working memory capacity does not influence overall performance. Results of hierarchical regression analysis…

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 of increase of the M demand of chemistry problems, having the same logical structure, on performance of students having different functional M capacity, cognitive style, and formal operational reasoning patterns. (Author/YP)

Provides information on (1) a general indication of change in the cognitive structure of students associated with chemical comprehension; (2) the comparison of clusters of concepts; and (3) a graphical representation of the links among concepts. Argues that constrained word associations serve as a useful tool for mapping aspects of cognitive…

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…

Examined is the predictive value of the cognitive variables of developmental level, mental capacity, cognitive style, short-term storage space, and numerical inductive reasoning for student achievement in college science. Included is a strategy for the development of materials which would allow students to develop problem-solving skills. (KR)

Reports on a study intended to determine the science education research interests of elementary teachers and to examine the data according to certain demographic variables. Results indicate that hands-on experience, science content, cognitive development and learning styles, problem solving, and teaching strategies were the top five research…

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,…
