Examines the impact of computer animations that illustrate chemical reactions occurring inside a battery on students enrolled in a college introductory chemistry course. Implies that instructor-guided animations may help students acquire a better understanding of targeted chemistry concepts, and that the relationship between narration, spatial…

Discusses variables related to task performance in the solution of the water-level problem, where subjects were asked to indicate the water surface orientation in a tilted vessel. Subjects ages 7 to 15 years participated. Suggests that field effects and the kind of rules in use contribute to the differences in performance, which can be shown even…

Notes Halpern's general support for Casey's model. Addresses differences in Casey's and McKeever's findings on familial handedness and females' spatial ability by performing another experiment in which data are analyzed according to two different theoretical assumptions. Addresses the question of the heritability of handedness by noting that what…

Describes two activities involving sorting, counting, and determining relationships that use sameness and difference, spatial skills, pattern identification, number bonds, and generalization. (DDR)

Performance on working memory span tasks by 53 children with intellectual disabilities (ages 11-12) was compared to 45 age-matched and 41 mental-age matched controls. Although consistency was poorer than children age-matched on all tasks, performance of subjects exceeded mental-age matched controls on visuo-spatial short-term storage and…

A study involving 93 children (ages 10-12), 295 with poor reading skills, found many children with dyslexia and some garden-variety poor readers showed significant left neglect on the Clock Drawing Test. In poor readers with dyslexia, spatial construction deficits were observed like those of parents with acquired right-hemisphere lesions.…

The effects of peer collaboration on mathematical and spatial reasoning were assessed for 152 fourth graders. Effects on learning with logical-physical materials were assessed 1 year later. Findings suggest that peer collaboration is effective for tasks that require reasoning but not for tasks that require rote learning or copying. (SLD)

The construct and predictive validities of the Perceptual Ability Test (PAT) were examined. The results indicate that each of the subtests exhibits different predictive validity. A linear combination of PAT subtest scores was found to be more predictive of first-year dental school technique performance than the total PAT score. (Author/MLW)

Provided are activities for creating tangrams. Illustrates how to make tangrams and use them. (YP)

Suggested that strategy choices for solving addition problems were related to numerical and spatial ability domains, while the speed of executing the component process of fact retrieval was related to arithmetic ability only. Findings supported the convergent validity of the strategy choice model and its discriminant validity. (RH)

Studied children's transitive inference where representation of premises provided contradictory information depending on position of two elements in a A, B, C series. Eight-year olds did significantly better on the more complex problems than did six-year olds, suggesting the presence of a developmental sequence of algorithms that enable children…

Presents activities using three-dimensional geometry to develop spatial skills. Includes reproducible student worksheets. (MKR)

Meta-analytic results reported show that in selected examples, mathematics-space correlations are higher in females than in males, with the difference becoming more pronounced with greater selectivity. Because these samples are of gifted or college-bound youth, explanations that emphasize career-directed attitudes are suggested. (SLD)

Examined the relationships between individual psychological characteristic, social contextual levels of family and culture, and mathematics performance in young adolescents. Found that scholastic ability perception is associated with the mathematics performance of students and that, at different levels of the social context, young adolescents'…

Twelve orienteers and four military scouts each described a critical incident requiring navigation skills in off-road terrain. Interview analysis generated a taxonomy of the navigator's cognitive model encompassing perception and use of environmental cues, problem-solving and decision-making strategies, and skill level. Contains 38 references. (SV)
