The effectiveness of different concrete and pictorial models on students' understanding of the part-whole construct for fractions was investigated. Using interview data from fourth and fifth grade students from three different districts that adopted the "Mathematics Trailblazers" series, authors identified strengths and limitations of models used.…

Media headlines often announce that U.S. students do not shine in international comparisons in mathematics and science, but seldom does any one focus on the specifics of how instruction differs among countries and how U.S. educators can alter their practices to improve student achievement. Examining key findings from the Third International…

The performance of two groups of 24 third-grade students practicing division problems was used to assess the effect of microcomputer drill programs on learning. An experimental group that used computer drill programs from the Milliken Math Sequences package was compared with a similar group that learned division using the traditional print drill…

The costs, effects, and utility of mathematics instruction supplemented by microcomputer presentations were compared with those of traditional classroom approaches for grades 3 and 5. The study was completed at a single school in a rural area of Saskatchewan, Canada, where two classrooms at each grade level were used in a pretest-posttest design.…

An investigation of how secondary students coped when taught binary arithmetic through a computer assisted instruction program used four treatment groups: learner control, learner control with advice; random program control, and adaptive program control. The random group performed less well, but no differences were found between learner and…

This is a case study that examines the effect of using presentations developed by teacher in addition to using commercially produced educational software CD-ROM in Audio-Visual Room/Computer Laboratory after classroom teaching, on students' academic achievement, as a method of Teaching Mathematics compared with only classroom teaching or after…

This study was conducted to determine the effect on achievement and attendance of providing students with computer assisted instruction (CAI) progress reports. Subjects included 105 at-risk eleventh graders in a remedial program funded by Holiday Inn. In a 5-week period during the summer, subjects were required to attend 5 CAI instructional…

The primary purpose of this study was to investigate the effects of three levels of personalization--individual, group, and non-personalized--on the achievement of seventh grade Hispanic boys and girls on mathematics word problems. Subjects were 123 seventh grade Hispanic students from a rural junior high school near Phoenix, Arizona. A pretest…

Examines the effects of systematic use of computers for the management of mathematics instruction upon mathematics performance in the elementary school. A model system for using computers to manage instruction within a student-paced, mastery-learning format is described, and treatments for the experimental and control groups are explained.…

Designed to improve student achievement in reading, language arts, and mathematics, the computer-assisted instruction (CAI) program in the Newark, New Jersey, schools comprises a regular component for remedial and average-achieving students, an enrichment component for higher achieving students, and a bilingual component for students having…

Discussion of the instructional effectiveness of educational software focuses on a study of undergraduates that investigated the effectiveness of a problem-solving program designed to assist students in solving nonlinear optimization problems. Results are reported that indicate manual procedures resulted in greater learning than use of the…

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…

Dolphin is a computer-assisted instruction system used to teach and reinforce skills in reading, language arts, and mathematics. An evaluation of this system was conducted to provide information to TSC Division of Houghton Mifflin regarding its effectiveness and possible modifications to the system. The general design of the evaluation was to…

This study was conducted to determine whether the traditional classroom approach to instruction involving the addition and subtraction of number facts (digits 0-6) is more or less effective than the traditional classroom approach plus a commercially-prepared computer game. A pretest-posttest control group design was used with two groups of first…

This study, which assessed the effectiveness of microcomputer-assisted instruction in assisting low achieving fourth to sixth graders to attain mathematics and reading mastery, found performance of only one experimental group statistically superior to that of the control groups, but no significant differences in attitudes toward school or sense of…
