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)

Surveys most important intellectual abilities for physics students. Found four factors: visualization; mathematics; logic; and problem solving. Explores the variations between respondent classification (researcher, teacher) and student goal (physicist, scientifically aware layman) on the ratings. (Author/YP)

Explores the relationships between seventh-grade students' misconceptions of genetics and natural selection and four cognitive variables: reasoning ability; mental capacity; verbal intelligence; and cognitive style. Reports that only the reasoning ability was significantly related to the number of misconceptions. (Author/YP)

Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)

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…

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)

Investigates specific strategies and activities used by two chemistry teachers to enhance student understanding of chemistry at the 11th- and 12fth-grade levels. Discusses teacher characteristics, class activities, classroom management, and monitoring for understanding. (YP)

Examines the effect of verbalization on the formation and retention of mental images in children in kindergarten, first, and fifth grades. Reports no self-generated verbalization effect with gender or ability level and no retention effect. (Author)

Describes a Teacher Intervention Program modifying classroom techniques and environments for fostering the participation of girls in high-school science classes. Reports that students who were taught by trained teachers, compared to students who were not, have higher scores on tests of attitudes toward science, perceptions of science, and science…

Examines achievement in individually competitive and cooperatively reward-structured environments during a seven-week class period. Reports no differences between the two treatment groups at posttest. (Author/YP)

Surveys the trait anxiety profile and preference concerning types of examinations of preservice science teachers. Reports that the students prefer examinations on understanding and analyzing rather than on knowing and remembering, and that students' anxiety states correlate with the type of examination and sex. (Author)

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Explores the sources of beliefs about science-technology-society topics and investigates the degree of ambiguity harbored by four different response modes, such as Likert-type, written paragraph, semistructured interview, and empirically developed multiple choice. Finds that mass media have a greater impact than science classes. (Author/YP)

Examines the effect of state-mandated policy, emphasizing control through performance-based instruction and student test scores as the basis for determining school accreditation, and the teaching and learning of science. Indicates that the state-mandated policy has some unexpected and negative results on teacher behavior. (Author/YP)

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)
