Various strategies for dividing time on a computer-assisted instruction system among a number of eligible students were studied using simulation models. Results indicated that different time allocation strategies make very little difference in achievement; a more important variable is the total amount of CAI time used by students. (Author/RAO)

In this paper we discuss an experiment that was carried out with a prototype, designed in conformity with the concept of parallelism and the Parallel Instruction theory (the PI theory). We designed this prototype with five different interfaces, and ran an empirical study in which 18 participants completed an abstract task. The five basic designs…

This article begins with a comparison of two groups of teachers, working on the same tasks in Analytic Geometry. One group has only basic experience in CAS-assisted problem solving, and the other group has extensive experience. The comparison is discussed in terms of the interplay between reflection, operative knowledge and execution. The findings…

The purpose of this project was to develop Web-based learning modules that combine (1) animated 3D graphics; (2) 3D models that a student can manipulate independently; (3) passage of time in embryonic development; and (4) animated 2D graphics, including 2D cross-sections that represent different "slices" of the embryo, and animate in…

In this study, I present an analysis of high school geometry curricula regarding mathematical proof opportunities. I examined eight U.S. high school level geometry textbooks, which were categorized into three main groups: technology-intensive, standards-based, and traditional curricula. I conceptualized "ideal" proving activity combining…

Colleges and universities have increasingly invested in specialized software and hardware designed to enhance and facilitate the instructional process for faculty and students. One type of technological assistance is commonly known as course management software (CMS). Once learned, these CMS packages can greatly enhance and enrich the classroom…

In 1997 the British Columbia Open University (BCOU) adopted a virtualization strategy based primarily on twinning off-line independent study distance education courses (textbook-based with study guide and telephone and e-mail tutor support) with alternate online versions (textbook-based with integrated conferencing and communications provided…

K-12 school practitioners and schools administrators need reliable results about the effects of instructional technology products as they strive to meet achievement compliance levels in politically accountable local and national contexts in the U.S. This study presents evidence regarding the effects of extensive engagement with computer-based…

Physical activity participation rates in the United States have been in steady decline for the last 25 years, so much so that 60% of youth ages 9-13 years get no physical activity outside of school. This state of inactivity indicates that promoting participation in physical activity at a young age is of importance. For the present study, a…

The bewildering number of available terminals which are offered to CAI users presents a rather formidable problem of which one to choose. This article surveys what appear to be evolving standards for terminals. The usefulness of these terminals for CAI purposes is discussed, together with the best known prototype exhibiting the particular feature.…

A study was conducted in the School of Medical Technology at the University of Illinois to determine the relative learning effectiveness of lessons taught by means of computer assisted instruction (in this case, PLATO) versus lessons taught by means of paper copies adapted from the PLATO system. While the benefits of translating paper…

Many new resources are available in education today. The author offers an evaluation of these resources, including their cost effectiveness. He discusses the resistance to change which has slowed acceptance of new forms of educational technology. He presents a table listing the major media of educational technology available today, together with a…

A follow-up was made to a feasibility study of the use of computer assisted instruction in teaching basic electronics. The study was designed to obtain additional empirical data, collected in a real time training environment, on the effectiveness of CAI as a teaching method relative to the conventional mode of instruction (CI). Four specific…

Within the context of a counterbalanced design, 63 female students were tested with a computerized Minnesota Multiphasic Personality Inventory (MMPI) and a group booklet mode of administration. State anxiety was measured before and after each testing session. The correlation between the computer-based MMPI scale scores and the booklet…
