Research in the area of amount of time spent on assignments and effect on course performance has focused exclusively either on the lecture or online format, but not comparison of the two. Nowhere has both modes of delivery been studied using an objective measure of course involvement. This study examines what is most significant in predicting a…

Describes a study conducted by the Department of Defense Polygraph Institute for their forensic science curriculum that investigated the effects of computer-based instruction on student learning of psychophysiological detection of deception test question formulation. Treatment of the experimental and control group is explained and posttest scores…

A study of undergraduate students investigated whether different rehearsal strategies are more effective in facilitating achievement, whether certain rehearsal strategies require learners to spend more time interacting with instructional content, and whether verbal or visual testing requires students to spend more time processing and responding to…

Discussion of various types of feedback used in computer-assisted instruction focuses on a study of low-ability eleventh graders that compared the effectiveness of answer until correct (AUC) feedback with knowledge of correct response (KCR) feedback. Achievement data on posttests as well as time data are analyzed. (11 references) (LRW)

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…

Describes a study that compared the effectiveness of computer-mediated communication systems for teacher education distance education courses with traditional classroom instruction and a correspondence course at Purdue University. Variables examined are described, including achievement test scores, time-on-task, and students' attitudes; and…

This metaanalysis of 32 comparative studies shows that computer-based education has generally had positive effects on the achievement of elementary school pupils. However, these effects are different for off-line computer managed instruction and interactive computer assisted instruction (CAI); interactive CAI produces greater increases in student…

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 a study of ninth graders that investigated the effects of learner and program control over content review in science-related computer-assisted instruction (CAI). Results of posttests, continuing motivation measures, and attitude questions are discussed; and future research is suggested. (35 references) (LRW)

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…

Designed to develop a more practical model for adapting context to learner interests, this study used computer-based instruction to make alternative contexts for statistics problems--sports, business, education, or no-context--available for selection by individual learners. The subjects were 227 undergraduate students enrolled in required…
