Whether or not the spatial cognitive development of students from distinct social-cultural milieus, specifically Anglos from the southwestern part of the United States and Native Turks, would proceed along approximately the same lines was investigated. The overall findings tend to indicate that at times the acquisition of spatial structures may be…

Describes four activities to develop visualization skills and the concept of dimensionality in which students (1) visualize transforming figures between the second and third dimensions; (2) identify the three-dimensional objects from their two-dimensional projections; (3) conjecture about the vertices, edges, and faces of zero- to four-dimensional…

Reviews research about young childrens' focusing on the ability to transform a perceived scene into another representation. Reports on a study of 109 children and 18 college-age students on their ability to mold a lump of clay into a three-dimensional figure. Finds that cognitive maturity alone does not automatically lead to competence. (CFR)

Preservice elementary teachers were videotaped teaching three self-designed micro-teaching lessons to their peers, and the videotapes were rated by elementary mathematics-methods instructors. Mathematics methods course quiz average, mathematics anxiety score, and spatial ability were investigated as potential predictors of videotape ratings.…

Thirty-five college students with learning disabilities (LD) and 25 students with a history of mild head injury (MHI) were compared on tests of neuropsychological, psychological, and academic achievement. Students with LD performed poorly on linguistically oriented psychoeducational tests, whereas students with MHI showed cognitive deficits in…

While the definition of learning disabilities has been the subject of controversy for decades, the current federal classification system identifies three specific areas of deficit: reading, written language, and mathematics and maintains the presumption that the disabilities are a result of a central nervous system dysfunction. In contrast to the…

Background: Several theorists maintain that exact number abilities rely on language-relevant processes whereas approximate number calls on visuo-spatial skills. We chose two genetic disorders, Williams syndrome and Down's syndrome, which differ in their relative abilities in verbal versus spatial skills, to examine this hypothesis. Five…

Many researchers and instructional designers increasingly recognise the benefits of utilising three dimensional virtual reality (VR) technology in instruction. In general, there are two types of VR system, the immersive system and the non-immersive system. This article focuses on the latter system that merely uses the conventional personal…

Geographic Information Systems (GIS) has tremendous potential for being a tool that can connect students to post school opportunities not yet known. The technology is robust and well developed, used by many workplaces and integral in a nation's future well-being and defence. However, despite many isolated attempts by teachers to incorporate GIS…

Historically, rehabilitation clinicians who work with people who are visually impaired (that is, are blind or have low vision) have relied on subjective checklists and clinical assessments to document the capacity of individuals to perform various tasks, including mobility, and to assess the impact of rehabilitation. Numerous instruments have been…

"Everyday Mathematics," published by Wright Group/McGraw-Hill, is a core curriculum for students in kindergarten through grade 6 covering numeration and order, operations, functions and sequences, data and chance, algebra, geometry and spatial sense, measures and measurement, reference frames, and patterns. At each grade level, the…

This digest discusses the origins of Howard Gardner's Theory of Multiple Intelligences, his definition of intelligence, the incorporation of the theory into the classroom, and its role in alternative assessment practices. Gardner defines intelligence as the "capacity to solve problems or to fashion products that are valued in one or more…

This volume presents 10 papers on research and methodology in learning and behavioral disabilities. Papers have the following titles and authors: "Memory Judgments and Allocation of Study Times in Good and Poor Comprehenders" (Ombretta Papetti et al.); "Diagnostic Spelling Analysis Within Curriculum-Based Measurement: Implications…

A quantitative synthesis of multivariate studies in science education during the past ten years yields evidence to support a model of achievement in science very much like that currently proposed in the literature of expert problem-solving. Despite previous claims, spatial visualization and verbal ability predict additional variance in achievement…

Confirmatory Factor Analysis was used to test first- and second-order factor models on cognitive abilities and their invariance across male and female samples. Subjects were a stratified random sample of 234 male and 225 female 15-year-old students in Singapore attending Secondary 3 (the equivalent of grade 9). Four first-order factors were found…
