Reports the results of cognitive test performance and early childhood activities in individuals with congenital adrenal hyperplasia, an autosomal recessive disorder associated with elevated prenatal adrenal androgen levels, demonstrating the effects of early exposure to excess androgenizing hormones on sexually dimorphic cognitive functioning.…

To help students develop measurement skills using metric units, an activity on making a box is described, with a worksheet for students. A second article discusses graphing elementary functions with a real domain, while a third article describes computer-assisted practice in graphing sine and cosine functions. (MNS)

The problem-solving skills of logical thinking, critical thinking, visualization, and communication skills are linked with some activities for students. Sample activities with logic, strategies and patterns, breaking fixed notions, open-minded problems, spatial visualization, and communication are described. (MNS)

Tests seven- , 10- , and 13-year-olds for developmental differences in processes and strategies involved in geometric matrix solution and the relationship between strategy differences and item complexity. (AS)

This paper explores the role of co-expressivity of drawing, speech, and gesture as sixth graders strive for intersubjectivity in their attempts to communicate solutions of a spatial reasoning task. Several obstacles to intersubjectivity are documented, particularly conflicts between a literal and geometric interpretation, limits of students'…

This paper discusses the differences between spatial and sequential learning, characteristics of individuals who exhibit stronger visual-spatial learning, and strategies for teaching children with visual-spatial strengths. Techniques include: (1) using visual aids, such as overhead projectors, and visual imagery in lectures; (2) using manipulative…

This study investigated the nature of spatial ability, as measured by four instruments based on spatial orientation and visualization, and its relationship to the mathematical performance of elementary school pupils. Participating in the study were 127 elementary school students, 72 boys and 55 girls, ages 10 to 11 years. Spatial ability was…

A collection of articles on the lifelong process of motor development focuses on: (1) neural changes in lifespan motor development; (2) the effects of developmental memory differences on learning motor skills; (3) physical growth and motor performance; (4) motor development in children with learning disabilities; (5) a motor development program…

Research is reviewed on human spatial cognition in real, everyday settings and is organized into five empirical categories: age, familiarity, gender, class and culture, and physical components of settings. (Author/DB)

Summarizes methods from a high school geography class that used examples from local geography to teach basic geographic concepts. Maintains that these illustrative examples can be used even in courses where the content is not local geography. Provides examples of local landscapes illustrating concepts applicable to the Brazilian rain forest. (MJP)

Describes activities in which students perform experiments with physical models that they create. Students develop geometric intuition and build a concrete foundation upon which abstract principles can be built. (DDR)

Describes an activity that helps students see how a paper map can represent a three dimensional object by having students build a realistic model that clearly shows what a contour line is and why it behaves the way it does. (DDR)

Discusses how educating children to use maps for navigation may enhance wayfinding skills as well as general representation and spatial skills. Documents need for innovative educational curricula to meet challenges of teaching map navigation. Describes development and evaluation of "Where Are We?" curriculum to simulate real-world…

Presents techniques for developing spatial visualization while dealing with concepts of area, proportion, and symmetry. Provides the objectives, directions, extensions, answers, and worksheets for each of the four activities. Describes involving parents. (YP)

Fifteen congenitally blind subjects were involved in a route-finding experiment in a complex architectural setting. Compared to sighted controls, subjects planned the journey in more detail, formulated more decisions, and used more units of information. On a cognitive mapping exercise, the blind subjects performed virtually as well as sighted…
