This paper reviews research on learning from dynamic visual representations and offers principles for the design of animations and simulations that assure their educational effectiveness. In addition to established principles, new and revised design principle are presented that have been derived from recent research. Our review focuses on the…

Discusses elements involved in the visual design of the computer-learner interface. Topics discussed include the need for consistency in screen layout; information representation, including accuracy in images and visual cuing strategies; and menu selection interfaces, or command representations, including their placement on the screen. (11…

Reviews possible sources of reinforcement in computer assisted instruction and systematic utilization of these sources in courseware design. Sources reviewed include reinforcement from the machine itself; from the content of the instructional modules and its arrangement in a learning sequence; and from sources external to the modules.

Describes computer-based voice recognition technology, including disadvantages; identifies vocabulary, training requirements, and ability to understand continuous speech as the basic characteristics of voice-recognition systems; describes applications in education and industry; suggests guidelines for design and implementation; and discusses…

Reviews the literature pertaining to the design of the layout of computer text screens as a means of maximizing comprehension in computer-assisted learning. The literature on the design of instructional text is also examined to extrapolate principles that may apply to screen design. (Author/LRW)

Computer based instruction (CBI) is composed of individual frames viewed one at a time. Compared to a typical textbook, CBI restricts the adult learner's capacity to access information from different parts of the lesson and to view complex presentations. Designers of CBI must compensate for these limitations by making a concerted effort to…

Drawing from the conclusions of research studies by linguists and psychologists, this paper describes four classes of principles for constructing readable prose for both print materials and computer screens: (1) global principles dealing with a schema-theory approach to discourse type, with topical focus, and with parallelism; (2) sentence-level…

Discussion of intelligent tutoring systems (ITS) focuses on what is required to evaluate the efficacy of an ITS. Research and development aspects of ITS are examined; and seven main principles that may be used to design, plan, and implement an effective ITS evaluation are described. (Contains 40 references.) (LRW)

Instructional design considerations involved in using level four videodisc systems when designing simulations are explored. Discussion of the hardware and software system characteristics notes that computer based training offers the features of text, graphics, color, animation, and highlighting techniques, while a videodisc player offers all of…

Defines the functions of windows that are used as visual display techniques in computer software systems, reviews research on the effectiveness of window environments, discusses knowledge structures, and presents principles for designing windowed environments based on research findings and individual differences and screen design research. (10…

This paper summarizes research in modern cognitive theory that relates to the role of computer drill and practice programs in learning and describes a prototype program that exemplifies recommended characteristics. Focus is on four major issues that are relevant to the design and optimization of computer drills: interference, spaced practice,…

Attempts to train learning strategies have not produced marked or lasting increases in academic IQ, probably because current training models fail to recognize the evolutionary nature of strategies acquisition. Empirical and theoretical evidence supports an incidental learning model, which engineers the instructional environment following study…

The development and evaluation of a potential viewdata-style delivery system for computer assisted learning (CAL) at the Open University are described. First examined are Open University problems with CAL and television delivery systems, which resulted in the consideration of a viewdata approach involving allocation of a small central processor to…

Discusses text displayed on computer screens and examines the effects of three layout variables--justification, line length, and leading--on reading speed and comprehension. Current literature on each variable is reviewed, and implications for the design of computer-based instruction are presented. (Author/LRW)

Examines methods of lecturing in the past, including blackboards, whiteboards, flip charts, and overhead transparencies; discusses the increasing use of computer technology and specifications for future systems; and describes possible scenarios for future lecturing technologies, including the generation of computer-assisted instructional materials…
