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)

Discusses computer assisted instruction programs that deal with the specific area of the modeling of systems and the programing techniques that affect their educational value. An environment intended to increase the impact of interactive CAI is described and developed. (Author/CHC)

Discusses the design and development of the user-computer interface in terms of the personal computer user's psychological needs and physical, perceptual, and conceptual contact with the system. Principles for the development of a user-system dialog that meets the requirements of transparency and visibility are suggested. Twenty-six references are…
