Complex computer and video games may provide a vehicle, based on appropriate theoretical concepts, to transform the educational landscape. Building on the original game object model (GOM) a new more detailed model is developed to support concepts that educational computer games should: be relevant, explorative, emotive, engaging, and include…

Although computer graphics professionals usually consider only technical graphic design issues, recent improvements may make the only limiting design factors the user's purpose, imagination, style, and taste rather than computer hardware or software technology. Computer graphics designers can be helped to avoid pitfalls by understanding the visual…

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…

This investigation of the encoding features of graphs begins with a description of a cognitive framework which allows designers to factor into the process of designing displays how people interpret the information found and what display properties are responsible for this interpretation. The framework also provides a performance measure for use in…

Discussion of online catalogs focuses on issues in interface design. Issues addressed include understanding the user base; common user access (CUA) with personal computers; common command language (CCL); hyperlinks; screen design issues; differences from card catalogs; indexes; graphic user interfaces (GUIs); color; online help; and remote users.…

In an increasingly technological society, there is a social need for designing communication technology around the perceptual abilities and cognitive strategies of people. A growing demand for information has created additional pressure on emerging communication technologies to provide electronic alternatives to the printed page. Design depends…

This four-section paper begins with a brief description of videotex and the paths its development has followed during its short lifespan. The second section examines how videotex systems should present and display information, and how such information should be internally organized so that it is maximally useful for the reader/user. The analysis,…

This paper examines graphic computing environments, identifies potential problems in providing access to blind people, and describes programs and strategies being developed to provide this access. The paper begins with an explanation of how graphic user interfaces differ from character-based systems in their use of pixels, visual metaphors such as…

In most existing computer assisted instruction (CAI), the nature of the instruction would not actually require a computer. Text is presented and read, questions are asked, and then materials are presented or reviewed depending on students' answers. There are two problems with this approach: computer capabilities for interactive task simulation are…

Outlines the design considerations that go into making an authoring system. Uses examples from the author's system, "Private Tutor," to illustrate. Emphasis is on the concepts that define the operation of the authoring system. Also discusses design principles of "Private Tutor" in relation to the Macintosh computer. (Author/LMO)

Computer assisted instruction, software design, and course organization are among the topics discussed in this varied, 15-paper collection which includes descriptions of specific projects, general essays and practical suggestions for improving or implementing computer-oriented instruction. The following papers are presented: (1) "Organization…

This analysis of trends in computer-based instruction (CBI) during the past decade briefly describes evaluation criteria from 1974 and discusses changes in attitudes toward CBI (costs, instructional effectiveness); system selection criteria (graphics, input devices, quantity and quality of software); the CBI marketplace (including transportability…
