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…

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…

Critiques comparative research and evaluation methods used to assess effectiveness of interactive video and proposes alternative models of research design that go beyond comparative analysis into understanding and control of the effective dimensions of interactive video, i.e., controlled correlation; instructional events, cognitive psychology, and…

This study investigated the degree to which seventh- and eighth-grade students of different abilities acquired strategic planning knowledge from a problem-solving computer game called Wumpus. Regression analysis was used to determine the influences of individual differences and either activating or modeling instruction, and to assess transfer of…

The suspected sources of confounding in current meta-analytic studies of computer based instruction (CBI) are uncontrolled effects of instructional method and/or the John Henry Effect (i.e., compensatory rivalry). To determine which confounding is most plausible, a random 30% sample of the 128 studies which formed the original Kulik meta-analyses…
