This study attempted to determine the influence of prior knowledge in mathematics of students on learner-interface interactions in a learning-by-teaching intelligent tutoring system. One hundred thirty-nine high school students answered a pretest (i.e., the prior knowledge in mathematics) and a posttest. In between the pretest and posttest, they…

This article examines three important facets of the incorporation of new technologies into educational practice, focusing on emergent usages of the mathematical tools of computer algebra and dynamic geometry. First, it illustrates the interpretative flexibility of these tools, highlighting important differences in ways of conceptualizing and…

Exploration of concepts crucial to development of new computer-based learning environments focuses on process rather than product and the computer's ability to record, represent, and communicate the underlying process. Cognitive, pedagogical, and sociological issues relevant to creation of learning environments in five domains (empowering…

Describes study of junior high school students in Israel that tested the effectiveness of microcomputer-based software designed to shape students' intuitions in the understanding of graphs of quantitative relationships. Retention and integration of microcomputer activities are discussed, and treatments for the experimental and control groups are…

Discussion of computer-assisted instruction and cognitive style focuses on a study of college students that investigated the relationship of student success in algebra and field independence-dependence. Topics discussed include the effectiveness of computers as instructional tools; treatments for experimental and control groups; courseware; and…
