Outlines a path analytic interpretation of data collected in light of the theoretical formulation of a dynamic model of memory. An investigation of industrial trainees' capacity to differentiate various ferrous and nonferrous metals is described which emphasizes the role of relational, strategic, and empirical knowledge in cognitive skill…

Evaluation of Israeli students, 392 in grades 7-9 and 381 in grades 10-12, in the domain of literature supported the construct validity of the 4 X 4 Structure of Giftedness Model, in which giftedness is conceptualized in 4 categories of general and specific intellectual ability and original thinking and 4 ordered ability levels embedded in a…

Investigates whether distinctions in cognitive structures between formal and concrete operational students effect their ability to produce an accurate cognitive structure, retain geometric content, and retain cognitive structures. Concludes that clear structures can be derived for the students. (Author/YP)

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 a study designed to identify 9 and 11 year olds' ways of drawing nets of solids and to provide opportunities for them to reflect on their models in whole class discussions. Results indicated that children's views of solids' nets progressed from more global and holistic to more quantitative and analytic. (MDH)

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does…

Described is research which sought to prove the hypothesis that mental models tend to preserve their autonomy with regard to the originals they are meant to represent. The results of this investigation involving 200 Israeli students are presented. (CW)

Concept maps provided a measure of subjects' cognitive structures before and after completion of an environmental education course. Concept maps were constructed from expressions taken from the issue "global climate." Expressions were assigned to one of three domains: science, technology or society. Maps were analyzed by constituent…

The usefulness of geography knowledge in a child's education is philosophically analyzed from two perspectives: (1) what geography knowledge should U.S. schools be teaching?; and (2) is there agreement about what types of geographical knowledge U.S. schools should teach? Only geographical knowledge that will be useful in life should be taught to…

The focus of this study was to portray the ideas that students with four years experience in learning physics developed in regard to the second law of thermodynamics. Data were obtained through 34 clinical interviews with grade 10 students. An analysis of student arguments revealed deeply rooted difficulties in using concepts that were learned in…

An investigation of Ontario high school students' understanding of acids and bases with quantitative and qualitative methods revealed misconceptions. A concept map, based on the objectives of the Chemistry Curriculum Guideline, generated multiple-choice items and interview questions. The multiple-choice test was administered to 34 grade 12…

During the last 10 years, cognitive science researchers have produced research findings that have great potential for increasing students' understanding of science. However, commercial publishers continue to produce textbooks and teacher's guides in traditional ways. This project developed a prototype unit which used an alternative approach to…

The purpose of this study was to investigate the effect of an eclectic thinking processes model on the logical reasoning abilities of students in grades six through twelve. The experimental school consisted of 159 students whereas the control school had 111 students. The Group Assessment of Logical Thinking (GALT) was administered to the sample as…

The purpose of this study was twofold: (1) to understand the conceptual frameworks that sixth-grade students use to explain the nature and structure of matter and molecules; and (2) to assess the effectiveness of two alternate instructional units in helping students change those conceptions. The study involved 15 sixth-grade classes taught by 12…
