Recategorized Wechsler Intelligence Scale for Children (Revised) subtest scaled scores for 192 learning disabled Navajo Indian children according to the system recommended by Bannatyne (1974). Results indicated that, as a group, the subjects failed to demonstrate the Spatial/Conceptual/Sequential pattern predicted by Bannatyne. (Author)

Describes a study that explores the instructional influence of presenting pictures at the molecular level when introducing chemistry concepts and solving chemistry problems. Explores the effect of the pictures on students' conceptions and problem-solving abilities. Contains 59 references. (DDR)

To determine if different levels of graphic presentation affected understanding, 131 middle school science students with high and low spatial ability were shown programs teaching concepts of molecular diffusion with no graphics, static graphics, or animated graphics. Students with low spatial ability benefited from animated presentations. Spatial…

A study involving 66 sixth-graders with learning disabilities, average achievers, and gifted students found gifted students used significantly more visual-spatial representations than the other two groups in solving mathematical problems. Students with learning disabilities used significantly more pictorial representation than their peers, a…

Specific difficulties for the secondary student with reading difficulties are described, followed by a literature review of most promising practices, including peer tutoring that incorporates comprehension strategy instruction and elaborative strategies in history and science classes. Research using "Inspiration" software to generate spatially…

The construct validity of three spatial ability tests was assessed by determining the correlation between the test results and student class grades in various subjects for 58 eighth graders enrolled at the Burris Laboratory School, Ball State University (Muncie, Indiana). Results do not strongly support any of the tests evaluated. (SLD)

This study was designed to: (1) examine modes of representations used by middle school students in a building description task; (2) investigate individual differences in representation mode; and (3) determine the effect of spatial visualization activities on students' preference for mode and success rate. The activities were reported as…

Discusses four activities focusing on communication about shapes and spatial relationships. The activities include requiring students to sketch patterns, and two-dimensional and three-dimensional visualizations. Provides several figures showing the geometric shapes. (YP)

Tests of a neuropsychological model for spatial orientation in the absence of vision were developed and administered to 31 children with congenital blindness. Results support the neuropsychological model and indicate that some congenitally blind subjects had focal brain damage, sufficient to impair their capacity to be accurately oriented in…

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

This study examined the arithmetic calculation abilities of kindergarten and first-grade children (n=108) with different patterns of cognitive functioning: low language, low spatial ability, general delays, and nonimpaired. Nonverbal, story, and number fact problems were differentially sensitive to variation in cognitive ability. (Author/JDD)

Two experiments with 172 undergraduate students (70 males and 102 females) examined the relationship among spatial, imagery, and verbal ability and the multitrial free recall of brief prose passages. Results suggest that the psychological mechanisms underlying prose learning performance clearly differ depending on the ability being examined. (SLD)

A multivariate hierarchical model of specific cognitive abilities was fitted to data from 196 adopted and 213 nonadopted children from the Colorado Adoption Project and 120 of their siblings to assess genetic influence on specific mental abilities. Genetic effects occur in middle childhood that differentially influence mental ability scores.…
