Sylwester says education must begin relying more on biology than social and behavioral science. All brain systems move from a slow, awkward functional level to a fast, efficient level. Contributions of metacognition, self-regulation, emotions, reflective and reflexive responses, comparison, and classification to cognitive development are…

Concerns development of children's understanding of data and classification. Studies three intact classrooms worked over several sessions to categorize drawings made by children and progressively mathematize their categorization rules. Concludes that by engaging with data characterized by prototypic rather than crisp membership values, students…

Proposes use of parallel computing systems to overcome the computationally intense clustering process. Results show some near linear speed up in higher threshold clustering applications, meeting the requirements to classify, group and process large document sets within nonprohibitive execution times. Includes graphs and charts. (JAK)

Discussion of assigning identifiers to books and bibliographic citations focuses on identifiers in the networked information environment, including URLs (Uniform Resource Locators); URNs (Uniform Resource Names); the OCLC Persistent URL (PURL); the SICI (Serial Item and Contribution Identifier) code; and the Digital Object Identifier (DOI). (LRW)

The Dewey Decimal Classification was not fulfilling genealogical researchers' needs, who search for ancestors by place (not subject). A new system that was developed at Rowan Public Library (Salisbury, North Carolina) is described. Also given are suggested additions to the Library of Congress Subject Headings to provide geographic orientation.…

An analysis of 205 records in the OCLC Online Union Catalog (OLUC) found considerable duplication among subject access points provided by title, subject heading, and classification number fields. On average, only 4.12 unique access points were found per record. The results suggest that online catalogs might outperform card catalogs more in…

Several recent court decisions provide ammunition for fighting over-identification of students who have impairments (like Attention Deficit Disorder) but who fail to meet the remaining eligibility requirements under Section 504 of the 1973 Rehabilitation Act. Distinguishing between Section 504 and IDEA requirements is crucial. (MLH)

Investigates ways in which people group or categorize documents associated with a voluminous work to guide the construction of organized displays for information retrieval systems. Discusses results of cluster analyses based on "A Christmas Carol" (Charles Dickens) and suggests implications for metadata standards and digital libraries as…

Introduces an activity on arthropod genetics that involves phenotype and genotype identification of the creature and the construction process. Includes a list of required materials and directions to build a model arthropod. (YDS)

Examines the information seeking and evaluative behavior of attorneys and explores the dynamic mental models attorneys construct. Highlights include domain-specific relevance; cognitive maps; current research on the retrieval performance of two full-text legal databases, LEXIS and WESTLAW; and implications of attorneys' mental models for legal…

Explores aspects of information retrieval complexity, specifically the demands on users and information systems, using a proposed query as an example. Discusses previous writings on subject access, search strategies and retrieval potential, and classification as a retrieval tool. An appendix shows the subject headings assigned to books in a…

Two experiments examined preschoolers' and adults' relative reliance on visual and verbal information in identification of animals and machines. Findings include both children and adults can use either visual or verbal cues in categorization, and a stricter definition is used in identifying animals. Results suggest that a perceptual to conceptual…

Analyzes the use of metapragmatic description in the ethnoclassification of language by native speakers on the Franco-Antillean island of Saint Barthelemy. A prevalent technique for metapragmatic description based on honorific pronouns that reflects the varied geolinguistic and generational attributes of the speakers is described. (Author/MSE)

A review of learning disabilities in gifted children provides definitions of "learning disabilities" and "giftedness", a classification of gifted students with learning disabilities, the importance of a multidimensional approach to identifying students with gifts/learning disabilities, characteristics, programming guidelines, teaching strategies,…

Argues that with regard to an important part of verbal morphosyntax (Tense-Aspect-Mood or TAM), it is possible to speak of a Standard Average European. Focus is on origins and evolution of TAM-markers, or TAM-auxiliation, suggesting that particular verb structures provide conceptual sources for auxiliation, and that it has an areal configuration…
