Garnett, Pamela J.; Treagust, David F. – Journal of Research in Science Teaching, 1992
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…

Niaz, Mansoor; Robinson, William R. – Journal of Research in Science Teaching, 1992
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…

Staver, John R.; Jacks, Tom – Journal of Research in Science Teaching, 1988
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…

Renner, John W.; And Others – Journal of Research in Science Teaching, 1990
The research reported in this study was done to evaluate the understandings developed by students who meet science concepts through a textbook. Findings indicated that concrete concepts were better understood by eighth grade students than formal concepts and that students achieved some understanding of some formal concepts. (CW)

Staver, John R.; Bay, Mary – Journal of Research in Science Teaching, 1989
Examines 11 elementary science texts in terms of conceptual structure and reasoning demands using concept maps. Reports that (1) the conceptual structures vary widely across texts; (2) most of the structures are well defined; and (3) the reasoning demands are above the developmental capabilities of most of primary-level children.

Wainwright, Camille L. – Journal of Research in Science Teaching, 1989
Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Meichtry, Yvonne J. – Journal of Research in Science Teaching, 1992
More than 1,600 middle school students, including an experimental group exposed to the Biological Science Curriculum Study (BSCS), were administered the Modified Nature of Scientific Knowledge Scale. Results indicate that the students utilizing the traditional science curriculum possessed a significantly better understanding of the testable nature…
