Examines spatial concepts required by young children for the understanding and manipulation of turn commands in Logo, and reviews the literature on children's Logo learning and the psychological-cognitive development of spatial concepts. Geometric concepts, alternative frames of reference, and the use of Turtle graphics are also discussed. (39…

The effect of computer-assisted instruction on spatial problem solving skills was examined in this study. Subjects were fifth grade students from nine classes, who were divided into three treatment groups in a nonrandom fashion: (1) computer-assisted group, which used computer software designed to help students improve spatial problem solving…

This aptitude-treatment interaction (ATI) study was designed to clarify the relationship between the aptitude variable spatial visualization and two modes of presentation of linear absolute-value inequalities. The modes of presentation include computer-enhanced instruction (CEI) and traditional. (Author/KR)

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Challenges the assumptions concerning the necessity of feedback in children's cognitive development. Suggests that during a certain and limited phase, cognitive development may occur due to cognitive restructuring. Discusses the implications of this for educational programs, especially computer assisted learning. (MJP)

Students' reactions and performances were examined when taught engineering geometry concepts using a standard microcomputer-aided drafting software package. Two sample groups were compared based on their computer experience. Included are the methodology, data analysis, and conclusions. (KR)

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…

Virtual Reality (VR) is a computer generated, multi-dimensional, inclusive environment that can build axioms of algebra into the behavior of the world. This paper discusses the use of VR to represent part of the algebra curriculum in order to improve students' classroom experiences in learning algebra. Students learn to construct their knowledge…

This investigation examined the effectiveness of training Japanese and American children with a visual animation/construction or verbal labelling strategy for solving computerized geometric matrices that were correctly or incorrectly completed and varied in number of elements (l to 3) and number of transformations (0 to 2). Subjects were 209…
