Although girls and boys were similar in cognitive skills and attitudes toward mathematics in grade 8, boys performed significantly better in mathematics by grade 11, even with mathematics background controlled. No sex-related difference in spatial visualization developed. (Author/GDC)

The investigation's purpose was to revise E. Hill's test for assessing the development of spatial concepts among visually impaired children, "Concepts Involved in Body Position and Space;" establish the test's validity and reliability; and collect normative data. (Author)

Reviews psychometic studies of human spatial ability and studies of environmental, genetic, hormonal, and neurological influences that interact in producing individual variation in spatial test scores. (MP)

Studied the development of third graders' spatial thinking during an instructional unit on area and motion. Found strong positive effects on the transformation of internalized images. Found initial gender differences in spatial thinking, but both boys and girls made substantial gains during instruction. Students applied a unitizing operation to…

Reports on the case study of a high school student using a computer-based tool called the Contour Analyzer to create graphs of height versus distance and slope versus distance for a flat board positioned with different slants and orientations. Focuses on visually recognizing the mathematical behavior of the slope versus distance function which…

Examined 5- to 12-year-olds' judgment regarding the behavior of balance scales and other levers whose arms varied in a causal or a noncausal variable. Results indicated age-related increases in correct judgments about the influence of physical features of objects at an earlier age than about spatial relations between objects. (MOK)

This article describes the modifications that 12 early childhood educators in Japan made to the Sorry! board game to encourage kindergartners' logico-mathematical thinking. Logico-mathematical knowledge is described as including classification, seriation, numerical relationships, spatial relationships, and temporal relationships. Examples of seven…

Thirty-eight people with visual impairments learned a 483-meter novel route through a university campus in four groups: verbalization, modeling, pointing, and control. The performance of all four groups improved with greater experience of the route, but the modeling group improved more than the control group. (Contains references.) (Author/CR)

Discusses a longitudinal case study of the literacy levels and styles of thinking of a group of males disabled in print acquisition. Finds that subjects rapidly perceived a whole gestalt, executed with an economy of language, and retained strengths in visuospatial, nonverbal processing, while losing verbal language abilities. (RS)

Investigates the relationship between the strategies used by preservice elementary teachers in geometric problem solving and two primary mental abilities--spatial visualization and formal reasoning. Reports that the two abilities were related to problem-solving performance, and the strategies used were related to achievement in the geometry…

Discusses teaching geometric concepts, including various shapes, patterns, and areas based on the NCTM Standards. Presented are activities for the geometric concepts. (YP)

Describes two instructional activities to develop spatial imagery and the pupil's responses to these activities. Discusses how the classroom atmosphere contributed to the success of the activities. (YP)

The literature is reviewed on the development of the temporal dimension in hearing-impaired students. Discussed are historical and cultural perspectives on the concept of time, perception of time, linguistic expression of time, and spatial and temporal orientation. Directions for future research are suggested. (Author/JDD)

Tested children with apparatus that dropped balls through clear or opaque interwoven tubes. Found that older children could solve configurations with greater number of tubes than younger children. Success with clear tubes did not transfer to opaque tubes. Significantly, errors were consistently directed to location directly below ball's last seen…

A cross-cultural quantitative review of contemporary findings of gender differences in variability in verbal, mathematics, and spatial abilities finds that the well-established U.S. finding of considerably greater male variability in mathematical and spatial abilities is not invariant across countries and cultures.
