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…

Primary advantage of authoring languages is special subroutines facilitating educational programing; primary disadvantages are execution speed, memory limitations, and little gain in programing ease. Primary advantage of authoring systems is menu-driven editors; primary disadvantage is significant limitation in the frame-based branching programed…

Investigates the effects of single- and multiple-window displays on the achievement of fourth-grade students during computer-assisted instruction by applying research-based window design guidelines. Results showed that, although there were no differences in window use, high ability students in the single window treatment demonstrated higher…

Describes study of Army aviation students who were enrolled in training program that was designed to compare the effects of two strategies of error remediation during computer-based instruction (CBI). Treatments for the two experimental groups and a control group that had no CBI are described, and results of pretests and posttests are discussed.…

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…

Describes study that investigated the effects of well-designed computer-assisted instruction (CAI) versus poorly designed CAI on college students' computing behavior, quality of prewriting, and attitudes toward the instruction. Comparisons are made with paper versions of both CAI displays, and guidelines for CAI design are presented. (38…

Describes a quantitative study that examined the effectiveness of interactive video (IV) instruction by using a meta-analytic research review of the literature from 1978 to the present. Effect size as a function of study variables is examined, and test of homogeneity on effect sizes is discussed. (25 references) (LRW)

Discussion of control over sequence of instruction in computer-assisted instruction (CAI) focuses on a follow-up study that examined the effects of the breadth and depth of menus and the meaningfulness of menu category names on the learning and attitudes of college students. Posttests are described, and results are analyzed. (16 references) (LRW)

Describes study of Israeli elementary school students that examined student attitudes toward computer-assisted instruction (CAI) designed to provide drill and practice in arithmetic. Attitudes are compared in relation to students' aptitude, gender, grade level, and socioeconomic status, and implications for the design of CAI systems are discussed.…

Describes a study of undergraduate preservice teachers that investigated three types of advisement--adaptive, evaluative, and combined--and their effects in learner-controlled computer-based instruction for learners with varying locus of control orientations. Posttest results are reported, and it is concluded that there is no significant…
