Word associations were used to map high school students' concepts of "chemical equilibrium" and "equilibrium." It was found that the preconception of the two concepts was differentiated on noncritical dimensions. (Author/CW)

Reports on a study in which clinical interviews were conducted with three elementary school children to determine the extent to which they held naive misconceptions about important biological topics, and to determine agewise trends in the development of biological knowledge. (TW)

Specific modes of formal reasoning and measurements of principled moral reasoning ability were obtained from 99 10th-grade students. Hierarchical relationships were found amoung variables with combinatorial and correlational reasoning accounting for 22 percent of the variance in principled moral reasoning. Theoretical and educational implications…

The effects of full-credit semester and all-year timetables on science attitudes and science achievement of grade 10 students was investigated. Findings indicated that students in all-year courses consistently outperformed students in semester courses in the cognitive domain, but there were no differences in the affective domain. (CW)

Performance on five logical, spatial, and formal tasks was used to make inferences about the reasoning structures of 101 middle and high school students. Findings (obtained during interviews) include grade level differences in performance and sex differences in performance on one of the tasks. Implications for instruction are proposed. (Author/JN)

Identifies an induced incorrect generalization as a generative cause for the formation of misconception. Analyzes students' protocol of an exploratory learning experiment about the laws of reflection of light. Suggests recommendations for textbook, teaching, and practical work. (Author/YP)

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…

Described are the comprehension monitoring abilities of science students when reading science textbooks. The incorrect use of schemata and the limiting influence of metacognitive abilities on the improvement of meaningful learning is discussed. (KR)

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)

Reports on the results of an investigation into the understanding of the concepts of basic electricity by French students from grade six up through the fourth year of college. Discusses the misconceptions formed and the challenges these present to physics educators. (TW)

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)

Calls for differentiating between three kinds of studies of students' conceptions in science, namely descriptive studies, explanatory studies, and studies attempting to foster conceptual change. Cites the literature about student perceptions and science instruction. (TW)

Discussed is the philosophy of the educational purpose of science education, the science involved, and the relationships of students and learning and students and content. A list of 14 references is included. (CW)

Discussed are the results of a test administered to nonmajor biology students on the topic of natural selection. The description of student conceptions, effects of instruction, and the effects of a belief in evolution are included. (KR)
