The purpose of this study is to present an analysis of how the structure and design of the Interactive 3D Graphics Learning Objects can be effective and efficient in terms of Performance, Time on task, and Learning Efficiency. The study explored two treatments, namely whole versus Part Presentations of the Interactive 3D Graphics Learning Objects,…

The purpose of this study was to examine the effects of visual representations and time-compressed instruction on learning and learners' perceptions of cognitive load. Time-compressed instruction refers to instruction that has been increased in speed without sacrificing quality. It was anticipated that learners would be able to gain a conceptual…

Investigated the effects and efficiency of mandatory and optional note taking by undergraduate students (n=81) during computer-based instruction. The required note takers entered notes on every screen of the HyperCard lesson; this group scored significantly higher on the post-test and took significantly longer to complete the instruction than did…

Undergraduate students who were given specific instructions to form mental images while reading a text passage containing spatial information scored significantly higher than the control group on a drawing posttest. Significant correlations also resulted between the test scores and both reading time and use of imagery. The use of imagery…

The effect of instructional analogy training on the level of immediate, as well as 14-day delay, comprehension of tangible and intangible physiological concepts was investigated. Ninety-four college-aged subjects were given training either with or without instructional analogies over five tangible and five intangible advanced physiological…

College students with varying degrees of prior conceptual understanding of a scientific topic were randomly assigned to a program-controlled or a learner-controlled treatment in a sequence of computer-assisted video learning. (Author/LMO)

Describes a study that was conducted at Tilburg University (The Netherlands) to test the impact of system and domain knowledge on search behavior in an online catalog. Highlights include time spent on task; the number of search patterns performed; and search patterns used most frequently. (11 references) (LRW)

Describes a study at the University of Southern Queensland (Australia) that measured self-efficacy for computer use of teacher education students at the beginning of their course and again following a semester in which some students had completed computer courses. The amount of time spent using computers contributed most to the variance in…

This study manipulated the timing and control of error feedback in problem solving and examined their effects on skill acquisition by 40 undergraduate students learning to program in the computer language Lisp under four error feedback conditions. These four conditions included two types of symbol-by-symbol feedback that vary in content, a…

Describes a study of college students that investigated whether various types of visual illustrations influenced abstract concept learning when combined with audio instruction. Discusses results of analysis of variance and pretest posttest scores in relation to learning performance, attitudes toward the computer-based program, and differences in…

A computer-assisted instruction (CAI) program using Utah PILOT programming language was constructed that includes the same objectives that are taught during the presentation of a traditional library tour. The amount of time necessary to complete the CAI program is approximately the same time needed by a student taking a library tour. The…

Discussion of hypertext structures focuses on three studies of preservice teachers that assessed the effects of different methods of explicitly mapping expert knowledge structures onto hypertext on the acquisition of structural knowledge. Topics addressed include time on task, semantic networking, cognitive limitations of browsing behavior, and…

Describes a study of college students that was conducted to investigate the effect of two review strategies on the recall of information from an interactive video program. Treatments for the active review group, the passive review group, and the control group are described. Recall posttests and amount of time required to complete the instruction…

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)

Although both learner control and feedback have been heavily researched, very little research has been conducted on giving learners control over the feedback which they receive. The purpose of this study was to examine the effect of learner control of feedback in a computer assisted instruction (CAI) lesson. The independent variables were type of…
