In this study, we meta-analyzed empirical research of the effectiveness of intelligent tutoring systems (ITS) on K-12 students' mathematical learning. A total of 26 reports containing 34 independent samples met study inclusion criteria. The reports appeared between 1997 and 2010. The majority of included studies compared the effectiveness of ITS…

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…

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…

Review of the research literature focuses on research comparing computer-assisted instruction with conventional instruction; basic research issues for instructional technology; implications of the information processing model; implications of cognitive strategies and knowledge organization for instructional technology; computers as tools for…

The "symbol systems approach" to the study of computers in education that is outlined avoids the pitfalls of past media research--particularly research on the effects of television on children's learning and knowledge--and asserts that media can be usefully distinguished in terms of the symbol systems they present and the kinds of…

Discusses the nature of interactive video, its educational use, evidence for its effectiveness, and the design of interactive video courseware. Use by the military and industry is also described, studies comparing video with other instructional methods are reviewed, and areas for further study are suggested. Ninety-four references are provided.…

This article addresses the problem of ascertaining the most suitable learning environment for learning diagnostic skills in health education--specifically diagnostic reasoning and the selection of therapy--through the design, development, and evaluation of a videodisc program. It describes the design, development, and formative evaluation of a…

The purpose of this report is to communicate findings on current knowledge of simulation design, development, and evaluation. Research on this project was guided by questions posed by the Defense Systems Management College in Fort Belvoir, Virginia. These questions fall into three categories: the constituents of good instructional simulations, the…

Proposes a framework to help course developers design criteria for optimal media deployment. The merits of radio, television, audio, video, and print are briefly compared with computer-based media and analyzed in light of six types of media characteristics: symbol system, access, controllability, student reactivity, interactivity, and adaptivity.…
