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…

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…

In order to compare the instructional effectiveness of realistic and non-realistic color cueing on visualized instruction, an instructional unit on the human heart, using slides and an audiotape, was presented to 244 college students. Four treatment groups received the same oral presentation, with the addition of different types of visual…

Third in a series on teaching methods in higher education, this updated volume reviews and evaluates research on audiovisual aids and related instructional hardware. While the emphasis is on the effectiveness of technical aids in higher education as instructional tools, some information on technical and administrative problems is also provided.…

This paper presents a global approach to the media comparison literature. Beginning with the pros and cons of media research, it discusses the results of both individual and meta-analysis research, compares the different methods researchers have used to determine media selection, and concludes with the most recent trends in media selection. It is…

Proposes directions to help researchers balance instructional technology goals with the performance of well-designed and scientifically sound studies. Issues concerning the external validity of studies, use of media replications, and learner control as a means of adapting instructional strategies to individuals are emphasized, and designs for…

This study examined whether the sources of information children use to substantiate story-based inferences are influenced by the medium of delivery. The 48 third grade students who acted as subjects were stratified by sex and randomly assigned to one of two media conditions; i.e., each child was presented an African folktale either (1) as a…

Relationships between media format, sensory channel, and cognitive information processing are not straightforward. Media format does not determine information processing and storage except when a deliberate attempt is made to model cognitive processes by manipulating the medium. Sensory channel only affects processing and learning for relatively…

This discussion of questions related to the most appropriate role for the computer in undergraduate postsecondary education begins by describing the Educational Testing Service's evaluations of two large-scale funded projects intended to stimulate the incorporation of computer assisted instruction (CAI) into undergraduate instruction--the…

Reviews some instructional media research that has been done in developing countries and makes recommendations for its improvement. Twenty-two references are listed. (Author/LLS)

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…

This review considers two major areas--research on educational media and research on school media centers (learning resource centers). Research reviewed in this report is limited to studies carried out in public school settings or that deal with issues of concern in public education. An introduction discusses the changing definition of…

Claims that computers and other high technology can replace teachers and staff, thereby reducing educational costs, are unwarranted for several reasons. First, most cost analyses focus on hardware costs, which are not the major factor directing the cost of computer assisted instruction (CAI). Second, technology is more likely to change the skill…

In response to Congressional direction, a quantitative, analytical review (a meta-analysis) was completed of interactive videodisc instruction applied in Defense training and in the related settings of industrial training and higher education. Over all instructional settings and applications, interactive videodisc instruction was found to improve…

Although some aspects of the educational effects of computer assisted instruction (CAI) are still unclear, some research findings are now quite definite. Two meta-analysis reviews of CAI have been completed at the University of Michigan, one on secondary school teaching and one on college teaching, and their findings have been independently…
