This paper explores the realm of evaluation within the domain of Intelligent Tutoring Systems (ITS). Toward that end, Littman and Soloway (1988) described two facets of evaluation: external and internal. Described here are a variety of procedures that they did not address and some that they discounted. One of the procedures not explored was the…

Four 2nd-grade students completed addition problems on a computer, using video games as reinforcers. Two variable ratio schedules of reinforcement failed to increase student accuracy or the rate of correct responses. In a no-games reinforcement condition, students had more opportunities to respond and had a greater number of correct answers.…

Designed to develop procedures and acquire information to help decision-makers establish policies for the use of microcomputers for computer-assisted instruction (CAI), this study involved the following steps: (1) a school-based research project was conducted to determine the costs and effects of microcomputer-assisted instruction; (2) an…

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…

Criticizes the statistical methods used in a previously published article that compared a commercially produced computer program with traditional teaching methods. Measures of instructional effectiveness are described, the assignment of student pairs is examined, and the use of blocking variables with analysis of variance is discussed. (LRW)

Discusses methods for teaching mathematics skills and describes a study of third graders that compared student performances on worksheets, a microcomputer drill and practice program, and daily one-minute timing procedures of precision teaching for independent practice of multiplication facts. Results indicate that precision teaching was the most…

This study addressed the assessment and development of problem-solving skills of college students. A mathematics-oriented computer-assisted instruction (CAI) program with an embedded general problem-solving strategy was developed. A related computer-managed instruction (CMI) module maintained student progress and phased out the problem-solving…

Discussion of computer-assisted mathematics instruction focuses on a study of high school students that examined the instructional effectiveness of computer-managed videodisc instruction for precalculus mathematics. Highlights include a comparison with traditional classroom instruction and theoretical perspectives, including sociocultural theory,…

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…
