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)

A discussion of constructing research designs that avoid the conflict between securing internal validity at the expense of external validity. Several such designs and examples of their application are offered. (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)

This paper poses and generates the answers to six questions about the use of newer media in education and the areas of disagreement that seem to recur as new media become available for teaching. Cast in the context of videodisks, those questions ask whether: (1) videodisk technology is more effective than traditional media in promoting learning;…

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…

Reconstructing media research so that generalizable knowledge can be produced requires an increased emphasis on attributes of media which interact with individual differences to effect learning. In order to accomplish this, media researchers must make a distinction between research "with" media and research "on" media. Privious efforts to…

Recent meta-analyses and other studies of media's influence on learning are reviewed. Consistent evidence is found for the generalization that there are no learning benefits to be gained from employing any specific medium to deliver instruction. Problems and suggestions concerning current media attribute and symbol system theories are described.…

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 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 is the most recent in a series of retrospective bibliographies on television and children. It includes an annotated listing of research reviews, position papers, and planning documents entered in the ERIC system in the years 1974-1977. Over 100 documents are listed in 14 categories: helping children to learn from television, new experimental…

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.,…
