Interactive computer simulations with complex representations and sophisticated graphics are a relatively new addition to the classroom, and research in this area is limited. We have conducted over 200 individual student interviews during which the students described what they were thinking as they interacted with simulations. These interviews…

Presents a set of guidelines for the display features and content of information that should be given to the learner in a computer-generated error message. Examples of common errors and suggested message displays are given. (8 references) (CLB)

Explains how the different levels of instructional videodisc programs serve different teaching situations. Characteristics of the software and the hardware system required for its use are described; the role of the teacher is discussed; and levels of interactivity between the student and the computer are described. (LRW)

Provides an example that illustrates the interrelationship of the factors that influence educational software portability. Nielsen's seven-level approach to human-computer interaction is used as the basis for a model for factors that influence portability, and five phases in the life cycle of a software product being adapted are considered. (10…

Identifies human factor issues involved in the student-computer interface in computer assisted instruction and makes specific recommendations for screen design. Factors considered include simplicity, spaciousness, relevance, standardization, changing display screen contents, color coding, shape and size coding, and brightness coding. (Author/LRW)

Provides an overview of the articles in this special issue, which deals with the portability, or transferability, of educational computer software. Motivations for portable software relating to cost, personnel, and time are discussed, and factors affecting portability are described, including technical factors, educational factors, social/cultural…

Describes a study of graduate students that observed the interaction between users of a graphical statistical package and a human playing the role of a simulated intelligent advisory system to guide the design of advice-offering user-assistance software. The use of video to examine the users' role in the interaction is discussed. (Contains 37…

Presents a list of recommended practices for designing computer-based instruction courseware based on principles derived from learning research. Research-based principles and the corresponding design practices are outlined for the areas of stimulus design, learner responses, feedback, and lesson control. (6 references) (CLB)

Discussion of the social role that computers play in the classroom focuses on an empirical study of human-computer interaction. Classes of high school and undergraduate students are described that were chosen to examine interactivity patterns among students with significantly different social characteristics. (11 references) (LRW)

Discussion of speech recognition technology and its use in computer-assisted instruction focuses on prototype systems designed for medical education. Commercial speech recognition systems are described, hardware and software requirements are examined, and the use of a speech recognition system to streamline an existing user interface is discussed.…

The Portable Courseware Project (PORTCO) of the U.S. Department of Defense (DoD) is typical of projects worldwide that require standard software interfaces. This paper articulates the strategy whereby the federal multimedia courseware initiative leverages the open systems movement and the new realities of information technology. The federal…

Arguing that what sets the computer apart from all other teaching devices is its potential for interactivity, this paper examines the concept of interactivity and explores ways in which its power can be harnessed and put to work. A discussion of interactivity in human-to-human communication sets a context within which to view human/computer…

This document presents a discussion of the development of a set of software tools to assist in the construction of interfaces to simulations and real-time systems. Presuppositions to the approach to interface design that was used are surveyed, the tools are described, and the conclusions drawn from these experiences in graphical interface design…

Describes adoption of microcomputer tutorial for library orientation at state-owned school of approximately 2,800 students. Highlights include advantages and disadvantages of microcomputer-assisted instruction, production of tutorial software, the program, evaluation, and revisions. Goals for library instruction and sampling of questions used to…

Discusses the application of computer based training (CBT) to human-computer interface design. Describes course considerations; courseware; and software environment for practice, and presents a case study outlining small group production of interactive guidebooks. Concludes that CBT can reduce instructional time and is an effective method for…
