The current emphasis on energy conservation in buildings must be balanced by a careful consideration of how proposed approaches affect building occupants. A headlong rush toward building designs that conserve energy at the expense of the quality of buildings as judged by occupants would be a very shortsighted approach. There must be a continual…

The major findings and generalizations of nine separate experiments summarized in this report have come out of a program of research on human factors in telecommunications and teleconferencing systems at Johns Hopkins University. These findings, already published in greater detail in the open literature, relate to (1) how people naturally…

Presented is a report on a Research and Development program in the use of computer-assisted instruction to teach mathematics in grades 4 through 6. Approximately 60 computer terminals of the PLATO type were installed in elementary school classrooms, 4 terminals per classroom. Each student received one-half hour of mathematics lessons, via…

This online pilot project demonstrates the feasibility of using the OCLC transaction tapes to create an online catalog, and the utility of the BRS database structure for loading this data and for online searching. It also shows the feasibility of a user-cordial interface for patrons and for staff and provides an opportunity to test many factors…

The Voice Interactive Analysis System study continued research and development of the LISTEN real-time, minicomputer based connected speech recognition system, within NAVTRAEQUIPCEN'S program of developing automatic speech technology in support of training. An attempt was made to identify the most effective features detected by the TTI-500 model…

The paper examines information systems from the viewpoint of implementations based on current knowledge and experience. It reviews studies that report on how information has been and can be communicated for its exploitation. It discusses various types of systems and schemes that have been developed to aid the information transfer process,…

The Network Measurement System (NMS) represents the implementation of a new approach to the performance measurement and evaluation of computer network systems and services. By focusing on the service delivered to network customers at their terminals, rather than on the internal mechanics of network operation, measurements can be obtained which are…

To minimize training time, an adaptive training model for optimizing path sequencing in computer aided instruction was developed. The model reduced a course to logical components or quanta, then plotted the material for possible sequences and evaluated each component quanta as to importance to subject assimilation. For implementation and testing,…

As a response to several specific economic analysis questions asked by the staff of Massachusetts' Management and Information System for Occupational Education (MISOE), this paper focuses on concepts of costs and benefits required for cost-effectiveness analysis, as well as the methodology of cost-effectiveness analysis. Useful as background…

This document is a translation and commentary on a French language document intended to introduce teachers to the concepts of computerized instruction. It is looked at from the viewpoints of teachers engaged in occupational, vocational, and career education and from the point of view of manpower studies. The potential uses and limitations of…

NLS-SCHOLAR is a prototype system that uses artificial intelligence techniques to teach computer-naive people how to use a powerful and complex text editor. It represents a new type of computer-assisted instruction (CAI) system that integrates systematic teaching with actual practice; i.e., one which can keep the user under tutorial supervision…

During 1968 the name of the project was changed from Stanford Physics Information Retrieval System" to "Stanford Public Information Retrieval System" to reflect the broadening of perspective and goals due to formal collaboration with Project BALLOTS (Bibliographic Automation of Large Library Operations using a Time-Sharing System).…

An instrument has been designed and used to quantify the degree of student dissatisfaction with computer-assisted instruction (CAI) experiences. The instrument, entitled PERPI-LPI, was derived from the service test Perceptions Etudiantes de la Relation Professeur-Etudiants (Student Observations on the Teacher-Student Relationship). It measures the…

A description is provided of the Experimental Time-Sharing System (ETSS), a multi-language, general-purpose time-sharing system designed to support a wide range of computing applications. Included among these are the control of an on-line behavioral research laboratory. Major topics discussed in the report are: 1) the system's hardward…

An individual trainer for giving students in the radar intercept observer (RIO) schools concentrated practice in procedures for air-to-air intercepts was designed around a programmable graphics terminal with two integral minicomputers and 8k of core memory. The trainer automatically administers practice in computing values of variables in the…
