The present paper represents a demonstration of how LISREL V can be used to investigate scale invariance (1) across time (its relationship to test-retest reliability), and (2) across groups. Five criteria were established to test scale invariance across time and four criteria were established to test scale invariance across groups. Using the…

This summary of the combined Hearing and Workshop on Applications of Computer-Based Information Systems and Services in Agriculture (May 19-20, 1982) offers an overview of the ways in which information technology--computers, telecommunications, microforms, word processing, video and audio devices--may be utilized by American farmers and ranchers.…

The first article, "LOGO and von Neumann Ideas," deals with the creation of new procedures based on procedures defined and stored in memory as LOGO lists of lists. This representation, which enables LOGO procedures to construct, modify, and run other LOGO procedures, is compared with basic computer concepts first formulated by John von…

Ways a microcomputer can be used to establish and maintain an evaluation database and types of data management features possible on a microcomputer are described in this report, which contains step-by-step procedures and numerous examples for establishing a database, manipulating data, and designing and printing reports. Following a brief…

If computer assisted instruction is to become viable in the speech communication classroom, the curriculum must be changed to include a discussion of the types of educational materials and formats that are possible and available for classroom use. Furthermore, the teacher and student need to know the capabilities of commercially available…

A product of the UNISIST International Centre for Bibliographic Descriptions (UNIBIB), this reference manual presents a standardized communication format for the exchange of machine-readable bibliographic information between bibliographic databases or other types of bibliographic information services, including libraries. The manual is produced in…

In order to study the processes people employ in reading technical material and the ways in which information engineering can facilitate those processes, 13 adults, including electrical engineers, stockboys, secretaries, graduate students, and teachers, were asked to perform an assembly task by following concise, step-by-step instructions provided…

The purpose of this study was to determine if individualized instruction structured by a teaching model which utilized student selected objectives and an instructional guide produced by a computer would change student achievement in physics measured by two methods and affect positively the students' attitudes toward the course of physics.

Gavilan College has purchased a small computer system which provides a workable student data base, a course data base, and an efficient student registration system. It can also be used to generate reports. This one system handles the record keeping and still leaves terminals free for instructional purposes. (DC)

The author discusses some approaches to assessing the impact of inaccurate information when the planning system involves formulae of the management accounting type or models of the operational research variety. The most appropriate method for quantifying information value in management information systems is through Bayesian analysis and decision…

Defining videotex and teletext as the most revolutionary innovations in communication since the invention of movable type, this paper describes The Interactive Videotex Project of public television station KPBS in San Diego, California. Following a brief overview of videotex and teletext technologies, the paper discusses (1) the development of the…

This computer-assisted curriculum is intended to be used to enhance a vocational mathematics/applied mathematics course. A total of 32 packets were produced to increase the basic mathematics skills of students in the following vocational programs: automotive trades, beauty culture, building trades, climate control, electrical trades,…

Proceedings of a 1986 CAUSE conference on the impact of converging information technologies are presented. Topics of conference papers include: policy issues in higher education, planning and information technology, people issues in information technology, telecommunications/networking, special environments, microcomputer issues and applications,…

This paper examines the administrative uses of the microcomputer, stating that high performance educational managers are likely to have microcomputers in their organizations. Four situations that would justify the use of a computer are: (1) when massive amounts of data are processed through well-defined operations; (2) when data processing is…

The first of three articles on the ways in which people formulate their observations, this paper considers the basic assumptions of both syntactic and paradigmatic models of cognition and their applications in natural (i.e., human) and artificial (i.e., computer) information processing. The analysis begins with background information on the nature…
