The role pictures and graphics can play in making Telidon, a Canadian home information retrieval videotex service, a viable communications medium is discussed. This report concentrates on contributions of theories of perception and cognition to knowledge of how different kinds of visual images can most effectively be used on Telidon. The issues of…

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…

Seventy-one college students were taught probability and statistics for one month by one of three methods: MP, manipulative-pictorial; P, pictorial; and S, symbolic. Analysis of variance yielded significant differences (p.05) between treatment groups for selected subtests of an achievement test and generally favored MP and P over S.

Three members of the Ohio State University Astronomy department developed an audiovisual program in Astronomy to provide a format for more active student participation than is possible in large lecture sessions. The program consists of 18 filmstrip/cassette modules and an integrated textbook which were utilized on an individual basis, allowing…

Research conducted over the past 80 years is examined to answer three questions on sensory modality as it relates to reading. In the 18 studies reviewed which relate to the superiority of one modality over another, there was no consensus regarding the relative effectiveness of modalities among adults. The evidence leans toward greater…

Effects of trait and state anxiety levels (low, medium, high), response mode (reading, constructed response), and program length (short, long) on performance for familiar and technical computer-assisted instruction materials were investigated. High trait anxiety was associated with high levels of state anxiety. Constructed response groups had…

A study was conducted of Tanzanian adolescent school children's responses to filmic elements. The design included a very large sample in a complicated factorial design, varying such factors as color, type of action, background and sound of the film, and the demographic characteristics of the subjects. Results showed that of these variables,…

With the advent of multi-screen capability in multi-media communication centers, it is possible to control the visual learning environment in a number of interesting ways. The basic assumption implicit in the concept of the multiple-image presentation is that it increases learning. A study tested the effect on learning of single- and…

An experiment compared the effectiveness of color and non-color (black-and-white) pictures in a paired associate learning task. The study also used individual eye movement quantifications as a predictor of preference for color and non-color pictures. Specifically, eye movement fixation patterns were used as indices of preference for color and…

This examination of computer-assisted instruction (CAI) covers early predictions concerning CAI, the variables that have been addressed by CAI research, guidance in identifying the effectiveness of CAI, and future directions for CAI in education. (MER)

Examined the responses of 58,288 college students to 8 scales involving 53 items from the National Survey of Student Engagement to gauge whether individuals respond differently to surveys administered via the Web and paper. Found that mode effects were generally small; however, students who completed the Web-based survey responded more favorably…

Discussion of collaborative learning techniques focuses on an empirical study that explored the impact on nontraditional higher education students of using asynchronous conferencing technology to complete collaborative teamwork. Highlights include gender differences; differences between face-to-face and asynchronous collaboration; and…

Reviews what has been learned about the use of motivational and informational feedback in traditional instruction, examines how this knowledge may be useful in the design of feedback for computer-based instruction (CBI), and discusses the relationship between feedback and learning outcomes. Further research needs are suggested. (13 references)…

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…
