The introduction to the theme of the issue of AVCR gives the rationale for concentrating on aptitude-treatment interaction research and summarizes and comments on the contribution of each author. (Author)

Author suggests a number of strategies for constructing a taxonomy that would take into account media, individual differences, and behaviors. (Author/HB)

The major theme is that better and more productive studies could emerge if media research would move out of its traditional either-internal- or-external validity conflict. (Author/MV)

Research on media and technology in education appears in many forms and styles. The results of this research so far has been quite disappointing, in that researchers have failed to point out the difference between research on media and research with media. Research also has tended to become highly specific, thus losing representativeness. A…

Considers the question of whether instructional methods are replaceable or interchangeable. Topics discussed include the influence of external events on learning and cognitive processes, media variables, linking instructional design to research on learning from instruction, construct validity, and an example of adequate instructional design and…

This report characterizes the resources that exist in the state of California which might be more fully utilized through legislation providing incentives for its development. Selected existing postsecondary education programs and selected information systems are reviewed to exemplify successful uses of instructional and informational media. An…

Review of the materials which came to the attention of the Educational Resources Information Center (ERIC) Clearinghouse on Media and Technology at Stanford University in 1973 leaves one with mixed feelings about the current and future status of instructional technology (IT). It seems as if officials in schools and government have negative…

Discusses different points of view about the impact of media on learning, motivation, and efficiency gains from instruction. The author's arguments about research and theory of media effects are summarized; reactions to the claim that media do not influence learning are characterized; and responses are given to Robert Kozma's specific criticisms…

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…

Reviews the developments in communications and educational psychology that have influenced present educational media strategies and shows how recent breakthroughs in learning theory and media research offer a new direction in the design and use of instructional media. (Author/JM)

Reviews issues raised in an earlier article that claimed that instructional media do not influence learning achievement or motivation. Topics discussed include differences between media and instructional methods; instructional technology; delivery technology; problems with meta analyses; thinking skills; cognitive processing; and research…

This study compared the use of an animated pedagogical agent (agent) with an electronic arrow and voice narration (arrow and voice) in a multimedia learning environment where 74 college level English as a Second Language (ESL) students learned English relative clauses. No significant differences in learning or performance were found between the…

Most evaluations of technology-based instruction are poorly designed because of failure to control three common confounding variables: (1) use of different instructional methods in different treatments; (2) presentation of different content in different treatments; and (3) the novelty of new media, which tends to increase early motivation and…

Defines authentic technology and describes how it can be developed and tested. Proposes collaboration among practitioners, technologists, scientists, craftspeople, and artists to develop authentic educational technologies. Offers three examples of current social and educational technologies. (AEF)

In the first of four symposium papers, Clark reviews the research on learning from media and uses his argument that media comparison studies show no differences in learning attributable to any one medium over another to dispute recent research on computer-assisted instruction. He also takes the position that the media attribute argument (i.e.,…
