The article investigates sustainable development from the holistic perspective, taking into account the complex nature of the world and the dynamism of the socio-economic systems. The study is interdisciplinary, as it addresses the issues of economics, mathematics and physics with the main focus on the modern perspective of sustainable development…

Reports on major change in computer software development process--the prototype model, i.e., implementation of skeletal system that is enhanced during interaction with users. Expensive and unreliable software, software design errors, traditional development approach, resources required for prototyping, success stories, and systems designer's role…

This critical analysis argues against the use of results from a computer model to project the growth and decay of cities as proposed by Forrester in his book "Urban Dynamics." (EB)

This demonstration of the use of a computer simulation research method based on the System Dynamics modeling technique for studying distance education reviews research methods in distance education, including the broad categories of conceptual and case studies, and presents a rationale for the application of systems research in this area. The…

Systems analysis and synthesis are applied to the supervision of school psychological services. A brief review of the key concepts of systems theory is followed by an explanation of one possible system for supervision. Illustrations of the usefulness of the systems approach to supervision are included. (Author)

This paper explores the use of a series of heuristic models that identify the interrelated components of the broader educational process. This heuristic schema was designed so that educators can examine the purpose and limitations associated with models and subsequently enhance their ability to guide changes within their own institutional setting.…

To address the question of why newspapers tend to become more and more fragmented internally and to propose a model of the interrelationships between the newspaper and its "operating environment," this paper draws on recent work by organizational theorists. Beginning by examining the central goal of newspapers, the first section suggests that the…

Educational change is a process occurring through time, a systemic and dynamic phenomenon in which every action leads to reactions in related areas of the system, and a multidimensional phenomenon requiring examination from the perspective of several disciplines. The success of an innovation depends on how the change process is managed, how the…

This document describes the construction/simulation software called Stella which can be used in the investigation of dynamic causal models. Topics considered are its built-in perspective of system dynamics and capabilities, its potential drawbacks, and its cognitive implications for educational applications. (JJK)

This paper examines trends and issues in international agricultural extension and offers seven reasons for the establishment of extension systems after World War II. It makes the case that, although the general situation is somewhat similar today, three current developments color and shape extension and may cause its demise: (1) institutional…

This paper, which updates and expands on a paper by Twelker and others that identified and described five instructional development (ID) models, presents a taxonomy for classifying ID models, comments on the limited degree of testing to which most ID models have been subjected, reviews 13 models, and provides a selected, annotated bibliography of…

Provides a summary of a series of research and development projects which investigated the reasons for failure in educational technology-based systems of instruction. Develops a new approach to the design of such systems and their subsequent implementation and control. A 17-item bibliography is included. (Author/CHC)

Although most models of connected discourse are strikingly similar in the types of relationships they describe, they are strikingly different in two areas: the unit of analysis and the dimensions on which cohesion versus coherence are described. Common systems for analyzing written text use the sentence, T-unit, clause, or proposition as the unit…

In the first part of the paper, the author discusses his observation that teachers perceive any form of theorizing in schools to be intellectually dependent on educational researchers. Teachers assume that their access to educational theories depends on a group external to themselves and that theory has little practical value in the classroom. In…

Several bodies of literature that shed light on some aspects of the relationship between information technology (IT) and research practice in science and engineering are reviewed. Subjects include: (1) the importance of calculation in research endeavors; (2) productivity in science and technology; (3) the philosophical differences between science…
