Includes patterns for and a brief discussion of the polyhedra: octahedron, tetrahedron, dodecahedron, cuboid, prism, and star. (PK)

Changes in intelligence among Swedish 13-year-olds during a 20-year period was studied. Results show: (1) the average of spatial and reasoning intelligence has risen; (2) verbal intelligence increased during the 1960s, but declined thereafter; and (3) by the 1980s girls surpassed in verbal ability and equalled in spatial ability. (Author/LMO)

This study of undergraduate and graduate students examined the potential relationship between spatial aptitude and videogame use to: (1) determine relationship between scoring ability on videogames and spatial aptitude as defined by standardized tests; (2) explore potential gender differences; and (3) examine effects of videogames practice on…

Reports possible validity of particular American Indian cognitive style based on the Bannatyne categories of the Wechsler Scales. Found statistically significant pattern of spatial ability, sequential ability, and verbal conceptual ability in 75 junior and senior high school Yakima Indian students. (LFL)

Describes characteristics of learning disabled teenagers. Describes results of a study of 331 secondary students who completed a self-report inventory showing that childhood learning disability characteristics persist into adolescence, most seriously in the areas of visual perception, fine motor skills, and the ability to write and make spatial…

Most experts believe that young children possess a substantial amount of informal knowledge about mathematics. The teacher's role is to create a link between children's ability to use informal math and the ability to understand the more formal math taught in elementary school. Teachers must help children construct and elaborate upon what they…

This study tested a causal model of the development of spatial visualization based on a synthesis of past and present research. During the summer and fall of 1999, 117 third- and fourth-year undergraduates majoring in architecture, mathematics, mathematics education, and mechanical engineering completed a spatial visualization test and a…

Noting that assumptions about the teaching and learning of early childhood mathematics have changed substantially since the 1970s, this chapter examines recent research that may inform curriculum development in early childhood mathematics. The chapter begins with a consideration of the theoretical perspectives for defining an appropriate…

Investigates the linguistic and cognitive aspects of the mastery of the time conjunctions "before" and "after" by young children. (EKN)

This study demonstrated an aptitude-strategy interaction in linear syllogistic reasoning; specifically, that the efficiency of each of four alternative strategies for solving linear syllogisms would depend on subjects' verbal and spatial abilities. The four strategies, as well as research methods in aptitude-treatment interaction, are discussed.…

Presents the results of an experiment that asked 53 middle school children to identify continent shapes and to arrange them to form a map of the world. Australia, Europe, and Asia were the most recognized. Misidentified and misaligned most consistently were Africa and Antarctica. Discusses possible reasons and teachers' responses. (MJP)

Examines children's knowledge and understanding of global spatial relationships. Utilizing cut-outs of continents to estimate their size in relation to Europe, the students consistently underestimated the size of Asia and overestimated Australia. Possible reasons for this are discussed and teaching approaches suggested. (MJP)

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)

Used path analysis to examine effects of spatial skill, math anxiety, and math self-confidence as mediators of gender differences in Mathematics Scholastic Aptitude Test (SAT-M) in upper third of college-bound adolescents. Found that mental rotation and math self-confidence indirectly mediated the gender-SAT-M relationship. Most of the mediational…

Described are the results of a spatial skills test designed to assess processing from 2-D to 3-D, 3-D to 2-D, and orientation. Results indicated that different aspects of spatial ability did not develop at the same rate, and the 3-D to 2-D skill took the longest to develop. (CW)
