Most past and current learning technologies have been one- or two-dimensional in presentation. This may be fine if one is looking at a map or even a fine painting. However, to fully appreciate the detail of a statue or a machine part, it is better to be able to look at it from all sides. Use of holographic images allows an item to be shared with a…

Discussion of instructional transaction theory focuses on knowledge representation in an automated instructional design expert system. A knowledge structure called PEA-Net (processes, entities, and activities) is explained; the refrigeration process is used as an example; text resources and graphic resources are described; and simulations are…

Defines instructional roles of dynamic visual displays (DVDs), including animation and interactive video, and provides guidelines for using them in media-based instruction. Topics addressed include theoretical bases; examples of strategic applications of DVDs; six instructional conditions for using DVDs; and considerations for the design and…

Presents a classification system of four microcomputer simulation types developed to evaluate their instructional processes: structured questions and graphics, variable-assignment exercises, diagnostic simulations, and group-interactive simulations. How this taxonomy contributes to three tasks associated with classroom use of software is…

Routines developed for an ongoing course in research methods and statistics provides examples of the custom instructional applications that can be created using extended BASIC and a light pen, including title and transition displays, progressive disclosure, animation, overlays, and simulations. Strengths of this technique are reviewed. (MBR)

Scenario refers to specific courses of action/events occurring within computer simulations and attempting to recreate lifelike situations. This article identifies critical features and their elements in designing effective scenarios in computer-based instructional simulations: (1) sequence; (2) operating procedures; (3) characteristics of…

Description of microcomputer-based simulations used to help teachers-in-training acquire basic teaching and classroom intervention skills highlights the Speech Synthesizing Simulation, which is designed to train speech language clinicians. Computer-generated verbal exchanges between a teacher and a class of computer-defined pupils during a…

Describes the design of "Pharyngitis in Louisiana," a computer-based epidemiologic case study that was created to teach students how to conduct disease outbreak investigations. Topics discussed include realistic content portrayals; graphics; interactive teaching methods; interaction between the instructional designer and the medical…

Discussion of electronic publishing focuses on the four main purposes of media in general: communication, entertainment, motivation, and education. Highlights include electronic journals and books; hypertext; user control; computer graphics and animation; electronic games; virtual reality; multimedia; electronic performance support;…

Identifies desirable features that should be included in software for effective instructional computing use. Highlights include design of learning activities; curriculum role; modes of instruction, including drill and practice, tutorials, games, simulation, and problem solving; branching; menu driven programs; screen displays; graphics; teacher…
