Summarizes findings from research related to spatial abilities. Provided are suggestions for developing spatial abilities. Lists nine references. (YP)

Two authors introduce the topic of visualization in mathematics education. Fourteen articles are briefly described. (YP)

Examines the relationship between visualization and the middle school mathematics curriculum. Gives an overview of where and how visualization interacts with the curriculum. Investigates the role of visualization in developing inductive/deductive and proportional reasoning. (YP)

New developments for solving the validation problem are applied to measuring and validating spatial modifiability. Results from 582 Air Force recruits support construct and criterion-related validities for the cognitive modifiability of spatial visualization items. Results also support modifiability as a direct measurement of learning ability.…

Comparison of the mental rotation skill of mathematically talented male (n=152) and female (n=143) high school juniors under both timed and extended time conditions showed higher performance by males under both conditions, but the male advantage decreased substantially when the effect of time was minimized. (Author/DB)

Presents interesting activities to develop mental imagery and the ability to transform these images. Concludes that using images facilitates mathematical thought in numerical and geometric settings. (ASK)

A study compared 11 Italian children (ages 7-11) with nonverbal learning disabilities (NVLD) to 49 controls on four tasks requiring visuospatial working memory and visual imagery. Results found the children with NVLD showed deficits in the use of visuospatial working memory and visual imagery. (Author/CR)

Uses a cross section to enhance three-dimensional knowledge of the anatomy of a canine head. Involves (n=124) veterinary students dissecting the head and experimental groups also identifying structures on a cross section of the head. Reports a positive impact of this experience on participant students. (Contains 52 references.) (Author/YDS)

Mathematics educators frequently recommend that students use strategies for measurement estimation, such as the reference point or benchmark strategy; however, little is known about the effects of using this strategy on estimation accuracy or representations of standard measurement units. One reason for the paucity of research in this area is that…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

This paper explores the preliminary results of an ongoing 3-year study of cognitive function and cognitive education among hearing-impaired persons (n=200) and considers these results in the context of previous studies. Cognitive task performance among the deaf was below average for the verbal and sequential skills associated with the left…

The influence of two sources of individual differences in acquiring knowledge from maps was studied: abilities and learning procedures. Twenty-five undergraduate students provided verbal protocols while attempting to learn two maps, and six effective learning procedures were identified: partitioning, imagery, memory-directed sampling, pattern…

Although the distinction between verbal ability and spatial ability is fundamental in all models of human abilities, differences in the relative strengths of verbal and spatial abilities have failed to show consistent interactions with instructional treatments. This study investigated the hypothesis that spatial tests measure different abilities…

Individual difference variables that are potentially related to cognitive mapping skills were examined, and good and poor cognitive mappers were compared in terms of those variables. Good and poor cognitive mappers were identified on the basis of the accuracy of their spatial knowledge about their own community. Four categories of individual…

This paper investigates one high school student's use of gestures in an interview context in which he worked on the problem of understanding graphical representations of motion. The goal of the investigation was to contribute a detailed analysis of the process of learning as it occurred over a short time period in order to contribute to the…
