Developed is an examination to determine a student's visualization capabilities. This examination has two versions, both developed to measure visualization ability, time to visualize, and reaction time. This test indicates the learner's ability to visualize complex three-dimensional objects from six principal views. Included are the results from a…

Described is a course that offers students the opportunity to learn the graphics language of computers in conjunction with the traditional engineering design graphics concepts. The course objectives, course description, course administration, and advantages to using the dual approach are included. (KR)

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…

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…

Reported are two separate but related longitudinal studies of two variables strongly associated with sex-related differences in mathematics achievement and enrollment, namely spatial visualization and confidence in learning mathematics. First, boys (N=33) and girls (N=36) in grades 6-8 who were discrepant in their spatial and verbal skills were…

The activities in this guide are designed for students in grades 4-10 and are intended to stimulate thinking about scientific and engineering careers, develop logical reasoning and problem-solving skills, promote positive attitudes toward mathematics, increase interest and knowledge about scientific work, strengthen spatial visualization skills,…

This research attempts to diagnose the skills required for successful spatial performance in order to provide a theoretical foundation for military training in such tasks as map reading, surveying, and navigation. It is known that successful performance on spatial tasks depends on task requirements (e.g., requisite knowledge, alternative paths to…

As part of an ongoing study of sex differences in spatial ability, three preliminary hypotheses on parental socialization, sex role socialization, and biological explanations were tested, using 139 high school seniors as subjects. The early findings indicated that there was no support for the hypothesis that boys and girls differ in how they view…

This study investigated the speed of encoding and rotation of images during simple spatial rotational operations to discover any similarities or differences in groups of differing spatial ability. This project was subdivided into five basic subproblems. First, research was done to arrive at a simple, easily testable information processing model…

An outstanding gain in their ability to visualize and create inventive and imaginative drawings after having been challenged by sensory activities indicates children's abilities to develop and use the right sides of their brains. (Author/SEW)

Described is the evolution of a multimedia approach for teaching Computer Aided Design (CAD). The presentation includes video tapes, a computer, an overhead camera, and hard-copy handouts containing class notes and CAD assignments. Also described is a complete "on-demand" training system for future use. (KR)

Eighth-grade students in bilingual classrooms explored the geometric concepts of reflection and rotation within a computer-based, dynamic, instructional environment. With initial differences controlled, treatment groups performed significantly better on concept formation and spatial visualization than did control groups receiving conventional…

Describes five skills underpinning the understanding of geometry for primary and lower secondary mathematics students. Skill categories identified include (1) visual; (2) verbal; (3) drawing; (4) logical; and (5) application. Gives examples of skills appropriate for Van Hiele levels 1-3. (MDH)

Presents activities designed to give students an opportunity to solve concrete problems involving spatial relationships and logical thinking utilizing hands-on manipulatives. Provides teacher instructions and four reproducible worksheets. (MDH)

Tests of spatial ability were analyzed for their analog (visuospatial) and nonanalog (verbal reasoning) components, using factor analyses of items and test scores. The self-selected sample consisted of over 2000 clients (average age about 26 or 27) employing the Johnson O'Connor Research Foundation's aptitude evaluation services in 12 metropolitan…
