Reports on two empirical studies that examined the nature and causes of information management indeterminism in an online research environment. A knowledge-based design for alleviating indeterminism which contains a system-generated thesaurus and an inferencing engine is proposed. (Contains 63 references.) (JLB)

This study found that categorization strategy training resulted in increased performance on unidimensional, bidimensional, and tridimensional sorting tasks by 4 males (ages 12-16) with autism. Three subjects also showed improvements on generalization probes and maintenance of performance. (Author/JDD)

Examines the structure and components of information storage and retrieval systems and information filtering systems. Identifies 13 components as representations of data objects (copies, excerpts, descriptions, abstractions, and identifying references) and functions that operate on them. Reduces the functional components to transformation and…

Two studies involving 195 undergraduates investigated memory errors occurring when the context standard used in judging target behaviors differs from the category norm standard available when behaviors are recalled. Results support a "natural" tendency to use the current categorical meaning of a judgment to reconstruct the referent of…

Cluster analysis grouped 621 jobs into 6 "contours" showing that from 1973-1990 employment distribution shifted away from 2 middle-quality to the 2 highest-quality contours; no change was apparent in the 2 lowest quality. Black and Hispanic men were affected by a worsening job mix and drop in the quality of low-skill jobs. Women experienced a…

Examines a model for children's strategies for inclusion tasks. Suggests that young children are not consistent in task strategies and that they display mixed response strategies. Strategies may change with development. (ET)

The use of taxonomies of types and levels of learning for student assessment in higher education is discussed. Five taxonomies designed for a variety of instructional areas are described. The reasons for their use are examined from four points of view: pedagogical, professional, quality assurance, and management. (MSE)

Examines the origins and parallel uses of the concept of "facet" in bibliographic classification theory and behavioral research. Suggests that social sciences in general were receptive to conceptual borrowing, but that library and information science as a discipline was relatively isolated. (contains 108 references) (Author/AEF)

A national study of 260 older adult education programs identified 5 models: (1) university-based; (2) Older Adult Service and Information Systems; (3) coalitions of religious congregations (Shepherd's Centers); (4) community colleges; and (5) senior centers. New roles for older learners are emerging in planning, teaching, governance, and community…

This article offers guidelines for applying creative thinking to modern life stresses, focusing on the organization of experience into meaningful patterns. Suggestions are drawn from typical adult life stages, changes in role perception, mental effects of physical exercise, the use of suggestive fiction, mental classification of experience, and…

Two experiments examined the development of recall organization by observing use of categorical and spatial clustering strategies and how encoding experiences and recall task influence degree of organization. Children and adults recalled furniture from their home. Older subjects organized items spatially; when recalling objects and their…

Summarizes the revised economic and policy types of the Economic Research Service's rural county classification system. The new typology is based on conditions in more recent years, includes Alaska and Hawaii, redefines persistent poverty, includes more county types, makes economic types nonoverlapping, and classifies counties designated as…

Presented a categorization of types of science education research, their possible contributions to cognitive science, and the potential of results from cognitive science for enriching the science education research accounts. Explored the relationship of an example of cognitive work to cognitive science. (15 references) (Author/JRH)

Proposes an instructional transaction class hierarchy and describes capability, knowledge, interactions, and associated transactions for three classes of transactions: (1) component transactions (identify, execute, and interpret); (2) abstraction transactions (judge, classify, decide, generalize, and transfer); and (3) association transactions…

This paper compared clinicians' diagnosis and DSM-III (Diagnostic and Statistical Manual), DSM-III-R (Revised), and ICD-10 (International Classification of Diseases) diagnoses of 52 individuals with autism and 62 nonautistic, developmentally disordered individuals. The DSM-III-R system overdiagnosed the presence of autism, and ICD-10 closely…
