Presents a database system development model in which theoretical support in the form of automated theorem proving is brought to bear on the problem of enforcing integrity, i.e., ensuring that the database system represents only those states and transitions that are possible in the world it models.

This description of the development of expert systems designed to solve management problems focuses on the issue of corporate divestment as an example. Software needs are discussed, and an example of a management expert system for divestment analysis at James Madison University is briefly described. (Author/LRW)

Presents a model of human information needs which classifies information need types by their inherent properties. The influence of information needs on human behavior, and the need to incorporate this concept into information storage and retrieval systems, are discussed. (15 references) (CLB)

Emphasizing more effective use of existing equipment, this article highlights distributed computing design considerations applicable to educational environments; identifies potential roles of networking in the provision of adequate teaching aids; presents a networking model; and describes the development of a distributed computing configuration at…

The use of general systems theory in the field of instructional systems design (ISD) is explored in this paper. Drawing on work by Young, the writings of 12 representative ISD writers and researchers were surveyed to determine the use of 60 general systems theory concepts by the individual authors. The average number of concepts used by these…

Presents a model for instructional software design as a collaborative effort involving computer scientists and educators, which stresses the process of design through documentation. The documentation used to exchange information at each phase of the process is described, and the advantages of this model are discussed. (CLB)

Defines interactivation; outlines a theoretical framework based on Merrill's Component Display Theory for systematic analysis of instructional strategies contained in conventional films and videotapes; and explores how computer-based interactive video systems can be used to improve strategies contained in conventional films and tapes through…

The study described in this paper produced a comprehensive model for the design of micro- or minicomputer systems containing concepts and practices that educational administrators can use for the successful design of school district computer systems. This report focuses on the methodology used to build the model, which included the following…

Designed to focus attention on the design process in such computer science activities as information systems design, database design, and expert systems design, this paper examines three main phases of the design process: understanding the context of the problem, identifying the problem, and finding a solution. The processes that these phases…

Considers possible contributions of developmental psychology to analysis and solution of practical problems by proposing a practical action model comprising the following: nature of the phenomenon or problem; existence of the phenomenon or problem; outcome in case of no intervention; goals for intervention; achievement of goals; and assessing…

This report begins with a summary of the implications of the Systemic Evaluation project as a whole, and then provides a framework for the commonplaces of schooling, along with an extensive sampler of the ways they can be used for building an information system. The first chapter presents some common conceptions of schooling that have typically…

Describes two research projects based on QUEST and proposes an information handling model. Design, interrogation, and evaluation of data files are discussed relative to restraints imposed by child's developmental stage and nature of software employed. Implications of computer-related information handling for curriculum design and children's…

A state educational indicator system being developed by the Pennsylvania Educational Policy Studies (PEPS) project at the University of Pittsburgh (Pennsylvania) is described. The extensive database that has been established as part of the PEPS project includes thousands of variables that are descriptive of the 500 Pennsylvania school districts.…

This report examines and evaluates the application of prototyping methodology in the design of a microcomputer-based online library catalog. The methodology for carrying out the research involves a five-part examination of the problem on both the theoretical and applied levels, each of which is discussed in a separate section as follows: (1) a…

Features articles on topics related to use of expert systems for training: machine intelligence effectiveness in military systems applications; automated maneuvering board training system; intelligent tutoring system for electronic troubleshooting; technology development for intelligent maintenance advisors; design of intelligent computer assisted…
