The purpose of this study was to measure and analyze viewers' electroencephalographic reactions to motion and still pictures, and to increase knowledge on the differential impact of the two modes on brain wave production. Since beta brain wave indicates focused attention, an additional purpose was to determine whether the two media differed…

Videodiscs have four characteristics that are valuable to the researcher, namely, that: (1) the contents of the videodisc are permanent, allowing multiple repetitions using the same material; (2) the order and sequencing of the material may be changed according to the focus of an instructional program or research study; (3) videodiscs can be…

A controlled experiment studying effects of adding voice-over sound to a silent electronic text service tested program acceptability and memory retention. Results indicate no significant differences in ratings for acceptability although the test for memory retention resulted in significantly higher scores for the sound group on recall and…

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…

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…

Describes a study which compared film and written material with regard to effects produced by order in which conflicting information is presented. Results indicate film is more influential and better recalled than conflicting written information: conflicting paragraphs produce a primacy effect, whereas analogous film segments produce no order…

This paper questions both what was being tested in prior instructional media research on the educational value of film and television and the value of some of those findings. An alternative way of conceptualizing the communication process that occurs when students view an instructional film or television program is proposed, which places viewers…

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.…

This study investigated the effectiveness of videotape as a medium for communicating skills in audiovisual instruction to education students at a university. Results indicate videotape mediated instruction can be better for developing skills in some practical aspects of audiovisual instruction than the lecture method. (MBR)

Past studies of media credibility have yielded contradictory results. In some research, television has the most credibility, while in others, radio or newspapers have the most. A probable reason for this is the way survey questions are phrased. In asking for a "major source of news," some questions focus on the "most likely medium" for news in…

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…

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…

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)
