This paper focuses on an approach to instructional development that consists of three basic stages interrelated by feedback. The first stage, system definition and management, is an exhaustive effort to define the problem, study the existing instructional context, and determine staff support and management controls. Stage two, design analysis and…

Few companies are comfortable with their performance appraisal system. The author suggests trying (1) systems that recognize competing priorities and attempt to alleviate conflicts through intelligent design and (2) management training that emphasizes the importance of providing staff with ongoing feedback.

Explains how to create an organizational system that will result in good performance. Topics discussed include process versus system; two views of a system, i.e., mechanistic and organic; and components of a system, including performance guides, measurement of results, feedback, and training.

John Goodlad (1958) stated that "Nowhere in education is there greater need for a conceptual system to guide decision-making than the field of curriculum." This research attempts to explore ways in which systems thinking can provide a conceptual system, to illuminate the study of curriculum and guide the design of curricula. (Author/RK)

Presents a model that places Boolean database queries into conjunctive normal form, thereby allowing probabilistic ranking of documents and the incorporation of relevance feedback. Experimental results compare the performance of a sequential learning probabilistic retrieval model with the proposed integrated Boolean probabilistic model and a fuzzy…

This paper reports on a transaction log analysis of 51,473 queries from 18,113 users of Excite, a major World Wide Web search engine. Approximately 2,500 of these queries were from the use of relevance feedback. Given the high level of research activity and historical success of relevance feedback in assisting users in locating relevant…

Reports experiments with a term weighting model incorporating relevance information in which it is assumed that index terms are distributed dependently. It is argued that, if high recall searches are required, relevance feedback based on the modified dependence model may be superior to the Boolean search. (Author/VT)

A theoretical framework used to derive a weighting mechanism for ranking output documents in Boolean retrieval systems is described in detail. A simple illustrative example is included, and the implications of such an approach are discussed. (64 references) (Author/CLB)

A conceptual framework of cognitive growth is sketched and a mathematical model of cognitive growth is presented with the conclusion that the most plausible model is a model of logistic growth with delayed feedback. The model is transformed into a dynamic systems model based on the logistic-growth equation. (SLD)

Describes rough sets theory and discusses the advantages it offers for information retrieval, including the implicit inclusion of Boolean logic, term weighting, ranked retrieval output, and relevance feedback. Rough set formalism is compared to Boolean, vector, and fuzzy models of information retrieval and a small scale evaluation of rough sets is…

Describes the three subsystems of an information retrieval system (document descriptions, queries, and matching algorithms) and argues that the interdependency of these subsystems requires adaptation for the system to perform when any component changes. An algorithm for redescribing documents, in response to changes in queries and retrieval rules,…

This paper examines strategies to enhance learning, based on innovations in technology. It represents an evolution of thought from the ancient masters, great thinking, and the Great Learning all the way to the present. A syllabus for the future is constructed, using a model of communication, the Rhetorical Systems Model. The model is based on a…
