Previous work assessing the effectiveness of computers in education has gone no further than acknowledging a network of interconnected variables (comprising a system) which contribute to computer impact and describing its component parts. An impact systems model developed by Glasman and Bibiaminov (1981) has been adapted to facilitate measurement…

A simulation model is developed to reflect characteristics of a typical information retrieval system on three specific microcomputer configurations using Cromemco System 3, Apple II, and Telima 1000. Systems are compared in terms of installation costs, think time, multiprogramming level, response time, and main storage utilization. Three…

This paper defines problems of school officials in dealing with the new information society, and suggests a planning framework applicable to the design of school and district microcomputer systems. Educators' problems in addressing the demands and opportunities of the emergent information society include inadequate comprehension of a major shift…

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…

This report examines and evaluates the application of prototyping methodology in the design of a microcomputer-based online library catalog. The methodology for carrying out the research involves a five-part examination of the problem on both the theoretical and applied levels, each of which is discussed in a separate section as follows: (1) a…

Summarizes the historical trend of distributing computer power within universities, and describes a model for an information technology environment for higher education. Based on a broad distribution of information and computing power, this model allows users to share information using micro- and minicomputers. (CLB)

Builds on a National Science Foundation (NSF) microcomputer based laboratory project to introduce system dynamics into the precollege setting. Focuses on providing students with powerful and investigatory theory building tools. Discusses developed hardware, software, and curriculum materials used to introduce model building and simulations into…
