Discusses conceptual differences between electronic and printed texts using a literature review that categorizes studies as convergent (i.e., electronic text as conceptually the same as printed text) or divergent (i.e., electronic text as conceptually different.) Four differences based on theoretical positions and findings from divergent studies…

Discusses research on the effectiveness of computer-based instruction (CBI) and proposes computer modeling as a tool to redirect CBI research toward more theoretically relevant and prescriptive research. Limitations of media comparison studies and media replication studies are described, and computer modeling in CBI research is reviewed. (48…

Describes three studies conducted at Pennsylvania State University to determine the effects on achievement and student satisfaction of various ratios of questions or highlights to text in computer assisted instruction (CAI) modules; question or highlight placement; and having questions or highlights on same or following page of target text. (MBR)

Describes a study that examined the relationship between academic ability or aptitude, as measured by grade point average and American College Test scores, and achievement with and without computer-assisted instruction. (15 references) (CLB)

A review of computer assisted instruction research and recent meta-analytical reports suggests that all research on the learning benefits of the instructional uses of computers should be halted until there is a plausible reason to expect that computers are instrumental in learning, since all existing evidence indicates that computers do not yield…

Current issues in educational communications and technology are addressed in this collection of 48 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., field dependence/independence, learning strategies, information processing, spatial ability, cognitive style, and cognitive strategies.…

Addresses the implicit assumption that instructional media represent meaningful experimental variables independent of instructional content or strategy. Results of computer-based instruction (CBI) studies (both well-designed and flawed) and meta-analyses are reviewed to support the authors' position that this assumption is invalid, and new…

The "symbol systems approach" to the study of computers in education that is outlined avoids the pitfalls of past media research--particularly research on the effects of television on children's learning and knowledge--and asserts that media can be usefully distinguished in terms of the symbol systems they present and the kinds of…

Current issues in educational communications and technology are addressed in this collection of 47 conference papers in which research reports predominate. Topics discussed include factors related to the learner, e.g., learning strategies, information processing, spatial ability, cognitive style, and cognitive strategies. Presentation format and…

Computer-based instruction (CBI) studies analyzed by Kulik et al. were examined to explore the validity of competing claims about the computer's contribution to measured achievement gains. Results suggest achievement gains found in CBI studies are overestimated and are due to uncontrolled but robust instructional methods embedded in CBI…

Current issues in educational communications and technology are addressed in this collection of 35 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., field dependence/independence, reading ability, learning strategies, and cognitive style. Presentation format and media and stimulus…

Criticizes the statistical methods used in a previously published article that compared a commercially produced computer program with traditional teaching methods. Measures of instructional effectiveness are described, the assignment of student pairs is examined, and the use of blocking variables with analysis of variance is discussed. (LRW)

This field study examined learning effects attributable to instructional design characteristics when eighth-grade science students used a print encyclopedia or a videotex version of the encyclopedia to write term papers. Results suggest that specific effects of instructional design characteristics of a delivery system are of a limited nature. (MBR)

Current issues in educational communications and technology are addressed in this collection of 31 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., aptitude, recall, computer anxiety, field dependence/independence, reading ability, learning strategies, and cognitive style. Presentation…

Current issues in educational communications and technology are addressed in this collection of 47 papers, in which research reports dominate. Topics discussed include factors related to the learner, e.g., problem-solving skills, motivation, comparison of instructional design strategies, effects of organizational cues and text layouts, and…
