Presents a computational modeling system (CMS) which is intended to provide scientific investigators with a unified computation environment and easy access to a broad range of modeling tools. A major objective of the design of CMS is to hide computational details that are irrelevant to scientific research. (53 references) (Author/JKP)

Discusses the design of computer applications, focusing on understanding design representations--what makes design representations work, and how, in different contexts. Examines the place of various types of representation (e.g., formal notations, models, prototypes, scenarios, and mock-ups) in design and the role of formalisms and representations…

Presents a formal object-oriented specification model (OSS) for computer software system development that is supported by a tool that automatically generates a prototype from an object-oriented analysis model (OSA) instance, lets the user examine the prototype, and permits the user to refine the OSA model instance to generate a requirements…

Considers the possibility of designing CAI (computer-assisted instruction) systems that are managed by semantic networks. Topics discussed include general descriptions of the suggested approach, lesson-presentation modes, and the architecture of a CAI system managed by a semantic network. (10 references) (MES)

Discussion of information systems methodologies that can contribute to interface design for public access systems covers: the systems life cycle; advantages of adopting information systems methodologies; soft systems methodologies; task-oriented approaches to user interface design; holistic design, the Star model, and prototyping; the…

Discusses knowledge, organization, and the organization and representation of knowledge. Addresses the relevance of international auxiliary languages as problems of development and use of special sign systems. Argues that--for computer realization of intellectual processes by modeling, not imitation--the psychological mechanisms of human memory…

Discusses one approach to project organization providing a baseline lifecycle model for multimedia/CBT development. This variation of the standard four-phase model of Analysis, Design, Development, and Implementation includes a Pre-Analysis phase, called Definition, and a Post-Implementation phase, known as Maintenance. Each phase is described.…

Proposes a framework for commercial Web application development based on prior research in hypermedia and human-computer interfaces. First, its social acceptability is investigated. Next, economic, technical, operational, and organizational viability are examined. For Web-page design, the functionality and usability of Web pages are considered.…

In this paper, a model is presented that uses educational dialogues to support the design process for learning support systems. The model is argued to provide a structure that links pedagogically motivated empirical studies of student-tutor-system interactions to problem specification and system design, and to result in the creation of learning…

Discussion of the portability of educational software focuses on the software design and development process. Topics discussed include levels of portability; the user-computer dialog; software engineering principles; design techniques for student performance records; techniques of courseware programing; and suggestions for further research and…

This report characterizes human problem solving in digital circuit design. Protocols of 11 different designers with varying degrees of training were analyzed by identifying the designers' problem solving strategies and discussing activity patterns that differentiate the designers. These methods are proposed as a tentative basis for assessing…

Presents a conceptual framework for building an intelligent documentation system (IDS) for computer software by integrating hypermedia and expert systems technologies. The need for online computer documentation for end-users is discussed, and elements of the synergetic model are described, including knowledge representation, the hypermedia…

This paper discusses the factors involved in making decisions about a multimedia display system. Theoretical factors, including gaining and holding learner attention, specific attention-getting devices, encoding and retrieval of information by learners, and presentation of information are considered. Ways that video is associated with computer…

Describes the development and validation of a microcomputer software system that enhances undergraduate students' interests in becoming engineering graduate students. The development of a database with information on engineering graduate programs is discussed, and a model that matches individual and institutional needs using Southwell's Relaxation…

The purpose of this study was to develop and validate a computer-based system that would allow interactive video developers to integrate and manage the design components prior to production. These components of an interactive video (IVD) program include visual information in a variety of formats, audio information, and instructional techniques,…
