Addresses philosophical grounds for artificial intelligence (AI) and cybernetic models by investigating three epistemological views--realism, a priorism, and phenomenology--to determine the problems in information transfer between a model and the real world. It is suggested that phenomenology demonstrates the most promise for opening up…

With the advent of web-based programs that automate the scoring of exercises, materials are now being developed from the outset with the capabilities of the web in mind. Materials developed without consideration of the web's capabilities, on the other hand, must be retrofitted. Texts that are retrofitted to the web have the advantage of being…

Purpose: This article seeks to address the interface between individual learning facilitators that use course management systems (CMS) data to support decision-making and course design and institutional infrastructure providers that are responsible for institutional business intelligence.

Purpose: The purpose of the paper is to evaluate the effectiveness or success of universities' portal implementation from the perspective of students as users. Adopting the model developed by Delone and McLean, portal effectiveness is defined as being composed of information quality, systems quality and service quality. In addition, the paper also…

In the policy making process, one of the important steps is the consideration of the consequences deriving from the alternative choices. For the case of information policy, the present research has begun the development of a methodology for doing so. The methodology chosen was modeling. Information policy modeling serves the dual purposes of…

In view of the apparent complexity and dynamism of the learner, only a systems approach to learning processes can provide a viable and practical frame of reference within which to conduct educational research. There are fundamental weaknesses in the current cybernetic model of learning, and therefore, it is useful to consider the learner as an…

The properties of an associative memory are examined in this paper from the viewpoint of automata theory. A device called an associative memory acceptor is studied under real-time operation. The family "L" of languages accepted by real-time associative memory acceptors is shown to properly contain the family of languages accepted by one-tape,…

Reviews the scientist practitioner model in counseling and examines problems associated with it. Discusses insights of general systems theory and Rychlak's insights into deficiencies in the current model of psychological research, and presents a revised model. (JAC)

A potential long range role for information science involves active participation in forming a complete suprasystem of knowledge which would unify the arts, sciences and professions. (Author/MM)
