The purpose of this study was to examine how 3-dimensional (3-D) models of the Solar System supported student development of conceptual understandings of various astronomical phenomena that required a change in frame of reference. In the course described in this study, students worked in teams to design and construct 3-D virtual reality computer…

An experimental design study compared the effect of periodic use of the "Geometric Supposers" software to nonuse on geometry achievement of two tenth grade classes (n=58). Results suggest that "Geometric Supposers" promotes higher achievement, particularly on Higher Level and Application Problems. No difference on Lower Level…

Examines the interaction between mode of computer assisted instruction and cognitive style on the understanding of concept relationships and mastery of factual information. Finds learners are more effective when matched to the appropriate mode of computer assisted instruction. (MVL)

This study highlights two groups of students enrolled in a college mathematics of finance course using same textbook and instructor. Experimental group used menu-driven symbolic calculators, whereas control group used standard scientific calculators. Significant increases in favor of experimental group were found both with respect to students'…

Discussed is whether embedding generative cognitive strategies in microcomputer courseware improves student performance on cognitive assessment measures and on insect classification tasks. The effects of transactional software on students' knowledge of insect anatomy and principles of insect classification were also investigated. (KR)

Described is a study in which seventh graders used LOGO in place of receiving geometry instruction. It was hypothesized that angle recognition estimation and construction would be higher for the LOGO group. Reports that a difference was found favoring the LOGO group. Provides a short history of the LOGO language. (MVL)
