This is the fourth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form. It describes the general functional and software requirements of an NAL system using external sources of bibliographic data. Various system design…

This paper discusses the use of a technique called windowing in computer assisted instruction to allow independent control of functional areas in complex CAI displays and simultaneous display of output from a running computer program and coordinated instructional material. Two obstacles to widespread use of CAI in computer science courses are…

The document highlights in nontechnical language the development of the Defense Documentation Center (DDC) Remote On-Line Retrieval System from its inception in 1967 to what is planned. It describes in detail the current operating system, equipment configuration and associated costs, user training and system evaluation and may be of value to other…

Redesign of human-computer interface for users of computerized information systems can make substantial difference in training time, performance speed, error rates, and user satisfaction. Information and computer scientists are using controlled psychologically oriented experimentation, and evaluations during system development and active use to…

This report describes an experimental system for remote direct access to files of computer-stored information which has been indexed by the Universal Decimal Classification (UDC). The data base for the experiment consisted of references from a single issue of Nuclear Science Abstracts. The Special Subject Edition of UDC for Nuclear Science and…

This is a collection of 12 working papers dealing with instructional management systems (IMS). The papers are divided into three sections--systems definition, pedagogical studies, and hardware/software studies. IMS is generically defined as a set of procedures and mechanisms for gathering and processing pupil data and returning useful information…
