Explains an investigation which examined Nigerian students' (N=200) ability to respond to depth cues and to visualize the effects of rotations. Study results indicated that performance on cues tests correlated significantly with performance on rotation tests suggesting that cues influence students' ability to visualize the effects of performing…

Investigated secondary-level students' (N=66) understanding of three-dimensional structures in biology. Results suggest that student performance is highly correlated with age, scientific ability, and sex. Suggestions for instructional improvement in spatial relationships are offered. (ML)

Demonstrates how three- and four-year-old children's (N=20) learning of a completely novel route across a city district is enhanced by an accompanying adult making the child aware of potential landmarks. The importance of permanent/ephemeral landmarks in the child's verbal and modelled-map accounts of the route and educational implications are…

Determined the factor structure of tasks which require students to visualize how diagrams should be drawn to represent effects of rotating three-dimensional structures about the three Cartesian axes. Results obtained from 149 English and 231 Singapore students show that visualization about X-, Y-, and Z-axes are factorially distinct. (DH)

Compared pairs of five- to seven-year-old children working collectively on spatial perceptive problems to control subjects working individually on the same problems. Although children working in dyads did not do significantly better than children working alone, there were several critical features in the frequency and quality of social interaction…

Ability to represent life-size space in a small scale was examined by asking 4-year-olds to create a small-scale model of a familiar preschool classroom. Study 1 children with high or low restructuring ability completed the model under guided or nonguided format. Guidance given to Study 2 children emphasized a functionally clustered classroom…

Results from three cognitive tests revealed few sex differences among 11-year-old students (N=2065). Neither question style (multiple-choice or structured) nor content (masculine or feminine) has any great effect on sex differences in performance. However, boys performed markedly better than girls on tests of spatial ability and mechanical…

Examined the relationship between performance on left and right hemisphere dominant measures of cognition and performance on dichotic memory tasks in 53 adults age 50 and older. Right hemisphere performance on dichotic and cognitive tasks showed a negative association with age while left hemisphere performance showed no decline. (JAC)

Investigated whether examining materials from several perspectives had greater effect on development of projective spatial abilities than examining materials from a single perspective. Results using 105 students (56 females, 49 males) favored the former approach. Also, sex was determined to have no direct effect on development of projective…

We report research on meanings of scale generated by pairs of 14 year-old students engaged in joint map-construction. Characteristics of the learning environment, such as the communicational orchestration, the use of experientially familiar objects in space as starting points for creating figural representations and the interrelated…

This study explored some aspects of reasoning needed to complete science performance assessments, i.e., students' hands-on investigations scored for the scientific justifiability of the findings. The reasoning demands of science performance assessments were studied focusing on three dimensions identified from a previous analysis of data from the…

What should constitute a preschool mathematics program for children ages 3 and a half to 5 years? What mathematical ideas could youngsters explore? This paper discusses six broad mathematical concepts for investigation by preschoolers: number, space and location, shape, patterns, measurement, and permutations. For each big idea, activities are…

This report describes a study that investigated the relationship between mental imagery and problem solving in physics, specifically in kinematics. A distinction is made between visual imagery and spatial imagery used in solving physics problems. The results of this study indicate that while spatial imagery may promote problem solving success, the…

Several critical questions concerning the topological primacy thesis were raised in an extensive literature survey (SE 531 428). Three points related to this criticism are discussed and reinforced, including a reexamination of Laurendeau and Pinard's data (showing that they do not support the hypothesis of topological primacy in children's…

Describes a study conducted with six pupils using Apple II Plus microcomputers and LOGO to determine whether five year olds can perform simple computer programing. This report describes the introductory educational games and activities, the pre- and posttests, some general findings, and possible implications for the teaching of problem-solving…
