The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

The major task in solving a physics problem is to construct an appropriate model of the problem in terms of physical principles. The functions performed by such a model, the information which needs to be represented, and the knowledge used in selecting and instantiating an appropriate model are discussed. An example of a model for a mechanics…

This brief paper presents background information and a description of the organizational structure and educational objectives of the Office of Computer-Based Instruction, formerly the Delaware PLATO project, whose name was changed to reflect the University's ongoing commitment to providing leadership in educational computing following the…

This report describes how Educational Radio and Television of Iran (ERTI) can use economic and manpower projection data in its planning. A summary of the conclusions reached in regard to Iran's most important education and training needs is followed by discussion of the particular types of information needed by ERTI and its availability. The…

The purpose of this research effort was to develop and evaluate a prototype system-independent Programming Design Guide (PDG) for one of the 13 offline job aids previously developed for use with the Instructional Systems Development (ISD) model. This PDG is intended to provide all of the guidance necessary for a user to implement the job aid on…

This paper documenting the development of the Individualized Study by Telecommunications (IST) instructional model describes both the design features of the model, and the current status of procedures used for developing and adapting courses for individualized study by telecommunications. A combination of audio technology, computer technology and…

THREE METHODS OF COST-EFFECTIVENESS ARE DISCUSSED--USE OF COMPUTERS, MATHEMATICS, AND EXPERTISE. THE USE OF EXPERTISE IS EMPHASIZED. THE DISCUSSION ON EXPERTISE JUDGMENT IS BASED ON PAPERS BY O. HELMER, WHICH ILLUSTRATE THE DELPHI METHOD OR CYBERNETIC ARBITRATION. ALTHOUGH COMPUTER AND MATHEMATICAL ANALYSIS (PARTICULARLY GAME THEORY) ARE BECOMING…

Four observations about computers and education are offered. 1) By 1972, development of new computer systems had fallen off, and several systems developed in the mid-1960's had been terminated. The decline was particularly intense in computer-based vocational guidance systems and in computer-assisted instruction projects. The only area showing…

This booklet presents the rationale and processes for ENSIM II, a computer-based long-range enrollment simulation model designed to consider variables not usually addressed in traditional projection techniques. The first ENSIM model was constructed for districts facing extensive residential growth and had as its primary focus the analysis of…

The National Academy of Sciences suggests models for biomedical research which include a biology-wide information system with computerized database accessible from a multitude of dimensions. Links could help discover whether toxic chemicals have effects similar to hormones. Commonalities from molecules to ecosystems might restructure available…

Through a discussion of research on institutions using computer-based planning models, this question is addressed: How does the institutional decision maker make decisions using state-of-the-art computing tools without neglecting nonquantitative realities? (MSE)

Describes a computer-based Wilderness Travel Simulation Model that reduces the complexity of the outdoor system under study, allows students to act as managers (devising and testing their own management strategies), and increases student exposure to characteristics of actual park and wilderness areas. Two scenarios of recreational use patterns are…

Provides a brief description of the University of Iowa (including the computing setting) and lessons learned while implementing an information technology plan. Such implementation considerations as sponsorship of effort, community involvement, and strategic choices are discussed. Refinements of the initial strategy are also considered. (JN)

INSTAN, a computer program designed to aid in appropriate media selection for classroom teaching, comprises three interrelated sections which focus on instructional objectives, the instructional environment, and instructional material selection. INSTAN is not described as an all-inclusive media selection model, but as a paradigm for further…

Presents methodological considerations in developing an automatic cheap algorithm for computerized path diagraming, gives some plotted results, and describes a program which produces the plots from an input matrix of path coefficients on a standard line printer. The program accommodates unidirectional and reciprocal causation and represents…
