Describes performance criteria for users of computer assisted instruction (CAI) that are used to provide users with feedback about their performance relative to other users. This study evaluated 146 novice users on their percentages of correct responses, time required for completion, and number of times the CAI tutorial was performed. (LRW)

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)

High and low level questions as determined by a panel of evaluators were combined with corrective feedback and attribute isolation feedback to form four versions of a computer-based science lesson. The sample consisted of 154 high school chemistry students in a suburban high school. The primary hypothesis was that students who received high level…

Describes a study of undergraduates that compared the effects of response-certitude adaptive and nonadaptive feedback in a computer-based lesson of verbal information and defined concept tasks. Effects on student performance, feedback-study time, and lesson efficiency are discussed, and implications for future research are suggested. (LRW)

Describes a study of undergraduates in a biology course for nonmajors that examined the effects of four methods of immediate corrective feedback during computer-based instruction (CBI). The relationship between types of corrective feedback and types of errors made by learners during CBI and during a later retention test is also examined. (33…

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.…

Describes a study that investigated the effects of learner control and program control, and lean and full modes of instructional programs, on the achievement, use of options, time on task, and attitudes of high-ability and low-ability students from grades 9 and 10 during computer-assisted instruction. (LRW)

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 study that examined the effects of embedded questions and review frames on learning from computer-based instruction as well as the effect of perceived need for training on performance. Experimental and control group treatments for management training are explained, hypotheses tested are presented, and results are analyzed. (24…

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)

Describes a study that was designed to investigate the interaction between three levels of instructional control (i.e., linear, mixed, and learner) and provision of an orienting activity on college students' learning of factual and procedural knowledge via interactive video. Instructional time and recall of facts and procedures are examined. (35…

Discussion of learner-controlled instruction focuses on a study of undergraduates that compared learner control with program control in interactive videodisc instruction for making an origami crane. Student performance, self-efficacy concerning the instructional task, time on task, and student attitudes toward the instruction are examined. (32…
