Discusses the use of icons in computer interface design. Highlights include picture processing time, complexity, recognition memory, differences between picture icons and picture/text icons, the use of color, size, placement, and touch design. (LRW)

Discusses the importance of the computer-user interface for instructional multimedia materials to motivate students effectively. Motivation, functionality, learner control, cognitive optimization, interactivity, cognitive load, and screen design are discussed. (LRW)

Identifies user interface problems as they relate to computer-assisted instruction (CAI); reviews the learning theories and instructional theories related to CAI user interface; and presents potential CAI user interface improvements for research and development based on learning and instructional theory. Focuses on screen design improvements.…

Effective message design for screen-based computer or video instructional programs requires knowledge from many disciplines. Evaluates current conventions and suggests a new set of guidelines for screen-based designers. Discusses screen layout, highlighting and cueing, text font and style, text positioning, color, and graphical user interfaces for…

Describes a Web site that introduces novice Web users to principles of design and navigation of instructional Web sites. Discusses the process involved in designing the site, lessons learned while developing it, and recommendations for further research. Includes a list of research-based guidelines derived from the literature in the areas of screen…

Discusses a prototype multimedia application that was designed to help college students solve problems and generate practice tests for an economics textbook. Highlights include step-by-step problem solving; a friendly interface; student tracking; inexpensive development costs; examples of screen displays; and generating random, scored tests on…

Computer-based instruction (CBI) has undergone tremendous changes in the past decade. This paper focuses on the following three areas of designing information presentation: (1) screen design literature is dated, and the existing guidelines do not allow for advances in computer technology; (2) open-ended guidelines may offer designers sufficient…

"Bohr's Atomic Model" is a small interactive multimedia program that introduces the viewer to a simplified model of the atom. This interactive simulation lets students build an atom using an atomic construction set. The underlying design methodology for "Bohr's Atomic Model" is model-centered instruction, which means the central model of the…

This paper reports on a project aimed at designing, implementing, and evaluating a hypermedia system, IPER-3, facing the three classical problems in the history of mathematics (i.e., trisection of the angle, quadrature of the circle, and duplication of the cube). The goal of the project is to study the opportunities offered by this kind of…

This article focuses on the effectiveness of computer-based instruction (CBI) screen designs, including their benefits and limitations, as well as human constraints in designing effective CBI. The paper begins with an overview of what comprises an effective CBI screen design, including characteristics of human factors, how information must be…

This paper presents interface guidelines from research at the University of Pittsburgh (Pennsylvania) School of Information Sciences in developing a collaborative, problem-based learning environment for the World Wide Web. The lessons learned are based on student use and evaluation of three interface prototypes over the course of 3 years and…

Modeling the functions of a teacher in a computer interface is not a new practice; most computer applications employ electronic performance support systems (EPSS) such as online help, wizards, coaches, and even some forms of artificial intelligence. This paper presents easy-to-implement strategies for increasing learner autonomy by embedding…

A difficult task in creating rich, exploratory interactive learning environments is building an environment that is truly engaging. Engagement can be defined as the nexus of intrinsic knowledge and/or interest and external stimuli that promote the initial interest in, and continued use of a computer-based learning environment. Complete and total…

This paper presents an information retrieval system for delivering educational visual materials through the World Wide Web. The system is designed to meet the following user requirements: lecturers prefer direct control over their visual resources; lecturers demand a browser-based interface that will allow them to create and modify their online…

This paper describes how student reactions shaped the design of a WWW (World Wide Web)-based course environment at the University of Twente (Netherlands), using the example of a first year course. The first section discusses the importance of user interface (re)design for WWW-based courses. The University's focus on student evaluations of…
