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…

Issues and implications related to the use of microcomputers for providing practice activities are addressed, including which skills should be automatized, requirements for ensuring that a skill has attained automaticity, scheduling and amount of practice, and the type and use of data that should be collected on individual student practice…

Emphasizing more effective use of existing equipment, this article highlights distributed computing design considerations applicable to educational environments; identifies potential roles of networking in the provision of adequate teaching aids; presents a networking model; and describes the development of a distributed computing configuration at…

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)

Discusses microcomputer network benefits; points out their current shortcomings in the areas of software availability and legal use, required equipment, and vendor reliability; describes how to set up a worthwhile specialized network despite these shortcomings; and outlines reasons for expecting networks to play a larger future role in education.…

Because of the need for models to illustrate some possible answers to practical courseware development questions, a specific, three-section model incorporating the Corrective Feedback Paradigm (PCP) is advanced for applying theory to courseware. The model is reconstructed feature-by-feature against a framework of a hypothetical, one-to-one,…

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…

A principal limitation of frame-based computer assisted instruction (CAI) results not from the characteristics of the computer medium, but rather from prior instructional design practices, specifically the logical abstraction of behavioral objectives. Learning hierarchy-based instruction implemented in the interactive computer-based medium results…

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)

Outlines several factors to be considered by teachers when designing text displays for computer assisted instruction. Types of frames--introductory, pretesting, teaching/testing, practice, criterion testing, and rule-example--are defined and discussed to aid developers in organizing a computer assisted instruction lesson. (MBR)

Reviews research on uses of computer sound and suggests how sound might be used effectively by instructional and interface designers. Topics include principles of interface design; the perception of sound; earcons, both symbolic and iconic; sound in data analysis; sound in virtual environments; and guidelines for using sound. (70 references) (LRW)

Describes the development of educational computer software called scenario software that was designed to incorporate advances in cognitive, affective, and physiological research. Instructional methods are outlined; the need to change from didactic methods to discovery learning is explained; and scenario software design features are discussed. (24…

Discussion of the design of computer menus focuses on two experiments that examined task time across several orderings of menu lists. Findings are described that demonstrated that good physical layout in screen design is not sufficient without good conceptual layout. The size of menu lists for maximizing efficiency is considered. (Contains 17…

Discussion of design principles in creating interactive video simulations for second-language learning focuses on two interactive video simulations on the Eurocentres Videodisc (ECVD). Four design principles are explained, instructional procedures involved in the ECVD are described, and learners' reactions are discussed. (four references) (LRW)
