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…

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)

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 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 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…

An examination of definition, causes, variables, and strategies of implementation suggests the kinds of data necessary for measuring school effectiveness. By focusing on students who first enter school below grade level standards and by understanding that student learning is embedded in a system of key elements or variables that, over time, are…
