Describes research that investigated the effectiveness of computer-based instruction (CBI) in support of mastery learning based on a study of 333 undergraduate students who used a CBI system called Management Information Systems Tutor (MIST). Student performance and time on task are examined. (Author/LRW)

This study was designed to determine whether systematically designed text augmented with compressed speech could increase the number of objectives achieved and reduce the amount of learning time needed for mastery of the objectives. Subjects were 78 students from 5 Florida schools with vocational education programs. Their reading levels ranged…

This study examined the effectiveness of a computer algebra system in teaching secondary school mathematics. Pre- and posttest results and time on task were compared for students receiving conventional instruction and those receiving computer-assisted instruction using an enhanced version of muMath, a standard computer algebra package. (four…

Presents a meta analysis which examines results of 254 controlled evaluation studies that compared student learning in classes taught with and without computer-based instruction (CBI). Outcome measures are described, statistical analysis and effect size are discussed, and results are reported that show that CBI usually produces positive effects on…

The Memphis Apple Classroom of Tomorrow (ACOT), one of seven ACOT locations, was a joint project of the city schools and Apple Computer. The ACOT consisted of a class of 30 fifth grade students in an inner city school, who were selected on the basis of the willingness of the students and their parents to participate and to use computers in the…

Describes a study conducted at the University of Iowa College of Dentistry that compared the effectiveness and efficiency of adaptive instruction with nonadaptive instruction using interactive videodisc patient simulations. The Dental Diagnosis and Treatment (DDx&Tx) System is explained, and problem-solving skills and study time are discussed.…

This meta-analysis of 49 comparative studies shows that mastery testing has positive effects on student learning, but the size of effect depends on the stringency of the criterion used and the degree of experimental control. The effects of instructional time, student attitudes, and differences in ability levels are also addressed. (Author/LRW)

Describes a study that compared individual computer-assisted instruction (CAI) with paired/cooperative CAI as a method of providing inservice training for cooperative extension agents on the topic of proper water well location and construction. Cognitive achievement and time spent on the lesson are investigated. (18 references) (LRW)

This study demonstrated that, although standard instructional design revisions of a traditional textbook chapter had no effect on teacher attitudes toward adoption of the material, the revised version of the chapter significantly improved student performance. Teacher and student participants in the study were from the St. Petersburg…

Discussion of digital audio in computer-based training (CBT) focuses on a study at the University of Central Florida that was conducted to determine whether the addition of audio to CBT had positive effects on undergraduates' cognitive achievement levels and to analyze its effect on time required to complete a lesson. (14 references) (LRW)

Describes an evaluation of the effects of the Mathematics and Science Computer Assisted Remedial Teaching (MASCART) software on students at the University of Botswana. Treatment of experimental and control groups is explained, effects on ability groups are discussed, and increased time on task and student motivation are considered. (14 references)…

This study investigated the effects of audio and text density on the achievement, time-in-program, and attitudes of 134 undergraduates. Data concerning the subjects' preexisting computer skills and experience, as well as demographic information, were also collected. The instruction in visual design principles was delivered by computer and included…

This paper reports on a study investigating the effects of studying alone or in cooperative-learning groups on the performance of high and low achievers. The effects of completing computer-based instruction using either learner or program control are also examined. A total of 92 sixth-grade students were classified by Stanford Achievement Scores…
