The question studied whether the specific seven TICCIT system colors used within color coding schemes can be a source of confusion, or not seen at all, by the color-blind segment of target populations. Subjects were 11 color-blind and three normally sighted students at Brigham Young University. After a preliminary training exercise to acquaint the…

A mainline CAI system is an individualized instructional system of major scope which uses the computer as a tool for instructional management and information transmission. Such systems are developed according to a design science approach and used as a less costly alternative to conventional instruction. In contrast, adjunctive systems have a much…

Reduced or stabilized costs of education can only be attained by positive changes in productivity as defined by the ratio of outputs to inputs. Educational units or districts could do research on productivity improvement at low costs if they combined for such research and development (R and D) activities. The area of productivity research that…

Results of the experience gained in designing and using an autonomous computer-assisted testing system are reported, including conclusions based on more than two years testing with typical classes. In this system, definitely expandable auxiliary storage for testing items and programs or scores is provided. Cathode ray tube display of questions and…

This report describes the development of computer programs called user agents, which, through interaction with users, can either learn new facts and store them in a data base or learn new procedures for data manipulation and represent them as programs. These programs are written in RITA, the Rule-directed Interactive Transaction Agent system, and…

One of the responsibilities of the National Science Foundation (NSF) is to support the effective dissemination of scientific information. The performance of this responsibility requires NSF to evaluate alternative information systems/services which are proposed for this purpose. This responsibility necessitates making decisions which are similar…

This paper describes the construction and implementation of an autoprogramming system. An autoprogrammer is an interactive computer programming system which automatically constructs computer programs from example computations executed by the user. The example calculations are done in a scratch pad fashion at a computer display, and the system…

Research on man-machine communication was examined to gain insight into techniques for improving interactive programs through the enhancement of communicative style. The human-computer interaction is compared to a conversation, and specific recommendations for improving this interaction are enumerated. The suggestions are general in nature and are…

The course contained in this book was written for training data processing machine operators; it is intended to prepare adults to qualify for an entry-level job. It is not aimed at developing high proficiency on any one machine, but rather at introducing the student to a variety of equipment, and developing an understanding of how the data flow…

A minimum of 30 minutes is required to learn even the rudiments of the command language (Symbolic Language). Although written instructions are helpful, practice is essential. The programmed instruction routines, which took approximately 20 minutes, were mostly of the 'yes-no' variety. Expanded routines, which would require other replies and would…

In contrast to conventional information storage and retrieval systems in which a body of knowledge is thought of as an indexed codex of documents to which access is obtained by an appropriately indexed query, this interdisciplinary study aims at an understanding of what is "knowledge" as distinct from a "data file," how this knowledge is acquired,…

The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic…

Project Intrex is a program of experiments intended to provide a foundation for the design of future information transfer systems, with the library of the future visualized as a computer-managed communications network. In order to discover the necessary facts, especially in the area of the user's interaction with the system, experimentation is…

This first of a four-volume series of reports summarizes the results of the MITRE Corporation's five years of technical, economic, and operational studies of interactive television. First reviewed are some major accomplishments such as: 1) the development of a new cable television (CATV) system configuration 2) the application for social services…

A system of computer-assisted data analysis (CADA) was developed at the University of Iowa to handle the mechanical, arithmetical and computational tasks associated with Bayesian statistical analysis. The original programs were subsequently expanded and a CADA monitor constructed to aid their use; a search was then undertaken to find a means of…
