Investigated was the effect of concept mapping on science achievement. It was concluded that mapping concepts prior to, during, and subsequent to instruction led to greater achievement. (CW)

Discusses the rationality of students' alternative frameworks by considering the role played by their beliefs, their understanding of other views, and the reasons for justification or rejection. Investigates the way in which 14-year-old boys see the effects of classroom learning experience on their ideas. (Author/YP)

This study sought to find out whether concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 grade-10 students participated in the experiment. Findings indicate concept mapping is significantly more effective than traditional teaching in enhancing learning in biology and reducing student anxiety toward biology.…

Describes five ways that high school students explain a chemical change. Discusses the differences in conceptual understanding of the students based upon their responses to questions about simple reactions. Presents additional classifications of conceptions of chemical reactions done by other researchers. (TW)

Proposes a framework for interpreting current research in science education. Presents four prototypes for describing research which are derived from comparisons and combinations of "spontaneous" and "formal" knowledge. Discusses possible applications of the use of the framework in science education. (TW)

Concept mapping was used to tap the conceptual disciplinary (science subject) knowledge and pedagogical knowledge of seven biology and six geography teachers with short or long teaching experience. Results indicate that knowledge in both areas is unsatisfactory, experience does not improve the knowledge, and teachers mastered disciplinary…
