The subject of access control mechanisms in computer systems is concerned with effective means to protect the anonymity of private information on the one hand, and to regulate the access to shareable information on the other hand. Effective means for access control may be considered on three levels: memory, process and logical. This report is a…

Described is The Source, a telecomputing network that gives the user access to thousands of programs and data bases, and the ability to communicate electronically with other users interactively and through electronic mail. It also provides access to the United Press International (UPI) wire service through the use of key words. (KC)

Discusses what generalized data-based management systems are and how they can be utilized in the field of education. Advantages of using the system and its effect on educational management are considered in detail. (DN)

Development and implementation of an off-line catalog card production system and an on-line shared cataloging system are described. An account is given of system design and equipment selection for the on-line system. File organization and programs are described, and the on-line cataloging system is discussed.

The evolution of a medium scale, general purpose, multi-language, time sharing computer system at the Learning Research and Development Center (LRDC) at the University of Pittsburgh is detailed. A strategy for the interfacing and control of laboratory devices is described with respect to several application environments; experimentation in the…

Rising costs of programming and program maintenance have caused discussion concerning the need for generalized information systems. These would provide data base functions plus complete report writing and file maintenance capabilities. All administrative applications, including online registration, student records, and financial applications are…

In 1972, Main Township (Illinois) High School District 207 eliminated its inhouse data processing operation and joined Educational Management Systems (EMS), a regional data processing cooperative. EMS was created by the Institute for Educational Research (IER), which first conducted a thorough study of school district's data processing practices.…

This paper discusses batch processing; and on-line, time-sharing operations, and their associate input/output equipment. Special emphasis is placed on electronic display equipment. It concludes that future equipment trends will allow the user more and easier access to the machine he uses. (Author)

As an illustration of an attempt at dealing with the problem of time-sharing small computers for laboratory control resulting from conflicts between real-time responsiveness needs and the matter of priorities and administration of the system as a whole, a description is provided of a time-shared system that is used to control and service multiple…

A medium sized time-sharing minicomputer performs both administrative and academic computing for the University of the South. Some advantages of the system include the opportunity for student access to the terminals, and the creation of new student jobs involving computer activities. Also, the minicomputer system hardware is less expensive to run…

The major features of Computer Managed Instruction (CMI) are diagnosis and testing, analysis, record keeping, and prescription. Diagnosis and testing are used to evaluate each student's performance at regular intervals. The results are analyzed to update the student's record and provide a prescription which suggests the learning process the…

Intended as an overview of the nature and use of computers in schools, this document describes the history and development of computers generally and of computer-assisted instruction (CAI) specifically. Included is information on several CAI systems currently in operation including (1) Programmed Logic for Automatic Teaching Operations (PLATO),…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…
