Reviews textbooks in use in the sixth-form classroom. Reports numerous examples of muddled facts, confusing explanations, and serious misconceptions. (DDR)

Investigated is the ability of high school pupils and university students to answer questions based on relationships within food webs using sound ecological principles. Research methods used and the results of this study are discussed. (CW)

Explores the extent to which third graders are consistent in their definitions and explanations of nine social qualities. For several qualities, children's definitions and explanations followed developmental predictions. For other qualities, definitions and explanations were attributed to previously identified moderation variables and age of…

Presented are four research articles and staff development activities. Included are: an activity used to stimulate discussion of the issue of balanced science; a constructivist approach to teaching electric circuits; a science grading scheme; and a discussion of priorities in science education. (CW)

Investigated 48 preschool, kindergarten, and first grade children's use of perceptual and taxonomic memory organization strategies. Addressed age differences in qualities, coordination, and effectiveness of study and retrieval organization strategies, and age and individual differences in relationships between memory knowledge and strategy use.…

The nature of cluster analysis and dendograms, subjects, tasks, and results of this study are described. Categories for problems were based on assumptions about the methods used by novice and expert problem solvers in a physics context. (CW)

Refutes the idea that critical thinking is not a skill by analyzing it from the phenomenological perspective of Edmund Husserl, and from the hermeneutic perspective of Martin Heidegger. Develops the thesis that critical thinking is a restructuring of schemata. Addresses the problem of attention or student engagement. (LS)

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)

Reports a study which identified different problem-solving strategies among Hong Kong high school chemistry students. Finds that student experts employed a recognition plus a working forwards strategy, whereas student novices attempted a means-end analysis to create a solution procedure. Comparisons were made with problem-solving in physics. (GG)

Presented are the results of an analysis of the cognitive stages of tenth-grade pupils using a six-week unit on the respiratory system. The research design, instruments, and data analysis are discussed. A variety of cognitive levels was found and may be related to learning outcomes. (CW)

Analyzes the concept of teaching from various aspects. Reviews research on students' conceptions of natural phenomena, conceptual change, and teacher thinking. Suggests an appropriate conception of teaching science. (YP)

Four experiments investigated children's ability to notice and remember events in which the acquisition of factual information occurs. Results indicated that children tend to report they have known newly learned information for a long time, suggesting that children have some understanding of knowledge acquisition, but not at the level of adults.…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…

Tested Cooper and Fazio's dissonance model. Subjects made arguments that were consistent or inconsistent with their attitudes and were provided feedback about consequences. Attitude-change effect only occurred when behaviors were both inconsistent and resulted in aversive consequences. Results suggest that cognitive inconsistency may be necessary…

Describes an exploratory study on the acquisition and use of knowledge representation skills and structures by sixth-graders, supported by a computer-based learning environment. Results indicated that symbolic structures can be taught successfully, and that students using them in the context of instructional tasks perform at the higher band of…
