Whilst spatial reasoning skills have been found to predict mathematical achievement, little is known about how primary (elementary) students' conceptual understanding of three-dimensional objects develops. In this article, we report a qualitative study and the impact of rich learning experiences on 48 Years 3-6 students' geometric reasoning…

Advanced displays and natural user interfaces (NUI) are a very suitable combination for developing systems to provide an enhanced and richer user experience. This combination can be appropriate in several fields and has not been extensively exploited. One of the fields that this combination is especially suitable for is education. Nowadays,…

This research aims to apply a depth sensor to create a human-body-sensing context for outdoor learning paths; it is conducted by incorporating both quasi-experiment and survey to compare students' cognitive learning outcome within the context and understand students' attitudes toward the context created. The result of ANCOVA indicates that the…

Pictorial depth perception of Tanzanian children was investigated using two versions of Hudson's pictures test. Revised version test scores were higher for all children. (ST)

In this experiment, 446 children, ranging in age from 5-10 years, were required to draw one object behind another in a situation in which adults invariably produce the further object partially occluded to the nearer. (MS)

Six motion projections were presented to first graders, seventh graders, and college students (N=72) in order to determine whether children can utilize the same motion parallax information as can adults. (MP)

An investigation of size accuracy and spatial accuracy of depth perception in a total of 227 African, Chinese and European children between 4 and 10 years of age. The pattern of results varied little between cultures. (Author/SDH)

The purpose of this study was to investigate the hypothesis that instruction in pictorial depth perception will enable children to perceive depth more often in pictures, to offer a larger number of appropriate explanations for their dimensional judgments, and to attain their best performances when realistc materials are employed. (Author/JM)

Tests of 172 fourth grade students in Zaria, Nigeria, supported the hypotheses that non-Western subjects' difficulties in judging depth in linear pictures are a function of individual perceptual organization, and that training could improve field independence and depth perception. Discusses child-rearing practices that may increase field…

Malawian children and young adults displayed sensitivity to static information for depth when stimulus objects subtended equal visual angles. When the more distant object was larger but subtended a smaller visual angle than the nearer, subjects tended to base judgments on retinal size. Motion paralax information increased accuracy of judgments of…

Television wide-angle lenses expand distances and increase apparent velocity, while long lenses compress space and reduce apparent velocity. Based on these assumptions, a study was conducted (1) to examine the ability of viewers of different ages to recognize how lenses change the "real world" they project and (2) to extend Jean Piaget's…

The degree of correlation existing between visual screening results obtained from the Keystone Visual Survey Telebinocular and the Titmus Biopter Vision Test was discussed. A sample of 59 children admitted to the University of Miami Reading Clinic during the 1969 summer session was used. They ranged in age from 7 to 16. All subjects were…
