HCI is a field which has an increasing popularity by virtue of the spread of the computers and internet and gradually contributes to the production of the user-friendlier software and hardware with the contribution of the scientists from different disciplines. Teacher candidates studying at the computer and instructional technologies department…

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)

Outlines the need for the development of computer-based curriculum in a trial set of courses that incorporates interactive technology. If the trial courses are successful it could lead to a major national curriculum development effort. (MD)

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…

Describes the design of a prototype of a computerized courseware production and presentation system that provides a user-friendly environment for the creation, maintenance, and presentation of courseware. Object-oriented material is discussed, types of operations that may act on the objects are explained, and interaction techniques are described.…

Compares the strengths and weaknesses of four authoring systems that can be used for courseware development: (1) Quest; (2) PCD3; (3) IconAuthor; and (4) Course of Action. Evaluation procedures used to assess their power, ease of use, and productivity aids are explained; menu and icon structures are described; and interactive design implications…

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)

This article uses the example of a single training course to show how to incorporate human factors into the interactive multimedia courseware development process. Three types of testing to identify human factors issues in courseware are discussed: usability testing, pilot testing, and field testing. (Author/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.…
