This study investigated the influence of cognitive support for learning computer-based tasks using animated demonstration (AD) on instructional efficiency. Cognitive support included (1) segmentation and learner control introducing interactive devices that allow content sequencing through a navigational menu, and content pacing through stop and…

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 study that was conducted to examine the effects of animation and practice on factual and application learning in elementary science computer-based instruction (CBI). The extent to which animation and practice promoted near and far transfer of learning outcomes is explored, and effects on processing time are examined. (31 references) LRW)

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)

Variables and conditions that influence the learning of computer-presented expository text were investigated in this study, in which on-screen underlining was used as a learning aid to increase "mindful" processing of information. The effects of three intervening variables--amount of invested mental effort (AIME), learning style, and…

Discussion of computer-based instruction and animation focuses on a study of undergraduates that investigated the effects of two computer-based instructional strategies, visual display and feedback type, on teaching how to troubleshoot electronic circuits. Time spent on various components of the program is also examined. (35 references) (LRW)

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 of Korean elementary school students that was conducted to investigate the effects of differing types of instructional control strategies and cognitive style on achievement in arithmetic skills using computer-assisted instruction. Hypotheses tested are discussed, time on task is investigated, and future research is suggested.…

This study investigated the effect of reward structure and group ability composition on small group computer-assisted instruction. Junior high school students practiced algebra in mixed-ability or uniform-ability groups, and rewards were based on individual performance, group performance, or a combination of both. (29 references) (Author/LRW)

The primary purpose of this study was to examine the effects of replacing multiple-choice questions in tutorial software practice interactions with a learning strategy (i.e., learner-generated summaries) on immediate recall. Subjects were 35 students--32 females and 3 males--from an undergraduate computer course in the College of Education at…

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 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…

Describes a study that examined the extent to which different levels of instructional control and varied learner characteristics affected performance and time on task, using interactive video in a college biochemistry course. Prior knowledge and learner internality/externality are discussed, and interaction between learner ability and…

Discussion of computer literacy, database technology, and higher-order thinking skills focuses on a study that compared the problem-solving performance of fourth-grade students receiving search strategy training during computer-assisted instruction with students who did not receive training. Time spent on problems and the number of correct answers…

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)…
