The eighteenth edition of the Dewey Decimal Classification system is reviewed. (SJ)

Reviews the history and development of the Dewey Decimal Classification, including the recent purchase of rights by OCLC and the production of a digitalized version. The contents and organization of the most recent edition are described and evaluated. (one reference) (CLB)

Two statistical measures are used to compare the Library of Congress and Dewey Decimal Classification systems by applying them to the library science portions of the two systems using a database drawn from MARC records. It is concluded that the measures characterize two different properties of dispersion. (Author/EM)

Explores the potential usefulness of the Library of Congress Classification (LCC) system as a tool in online retrieval. Unique features of LCC are described and a theoretical analysis of its potentials and limitations in terms of subject browsing, enhanced vocabulary, and class number searching are presented. (CDD)

A diminished top-down influence has been proposed in autism, to account for enhanced performance in low-level perceptual tasks. Applied to perceptual categorization, this hypothesis predicts a diminished influence of category on discrimination. In order to test this hypothesis, we compared categorical perception in 16 individuals with and 16…

Rudner (2001, 2005) described an expected classification accuracy index for determining the asymptotic expectation of accuracy of classifications of examinees into score categories. This article expands on that exposition by evaluating the index as it is likely to be used in practice (as a point estimate of classification accuracy), provides a…

Purpose: The purpose of this research is to show how the self-archiving of journal papers is a major step towards providing open access to research. However, copyright transfer agreements (CTAs) that are signed by an author prior to publication often indicate whether, and in what form, self-archiving is allowed. The SHERPA/RoMEO database enables…

This report examines whether knowledge about function influences the formation of artifact categories in 11-12- month old infants. Using an object-examination task, a set of artificial stimuli was presented that could either be grouped according to overall similarity or according to similarity in one functionally relevant part. Experiment 1…

We investigated how exposure to pairs of different items (as compared with pairs of identical items) influences 10-month-olds' (n=79) categorization of horses versus dogs in an object-examining task. Infants responded to an exclusive category when familiarized with pairs of different items but not when familiarized with pairs of identical items…

The ability to sequence genes has vastly altered our understanding of higher-level relationships among organisms such as those found at the kingdom level. It is important for biology teachers to incorporate these new views and not retain outdated concepts still present in some textbooks. This article provides an overview of our new understanding…

In this paper we examine the development of children's metamemory and provide practical implications of research findings for the classroom. In the first part of the paper we define and discuss the global concept of metacognition, the component processes of metacognition and the importance of each component to children's learning. We…

The results of Romanian school students in Science PISA and TIMSS testings have been and continue to be systematically slack. In the present paper we intend to do a comparative analysis of Science curriculum TIMSS 2007 and Romanian Science school curricula of 4th and 8th grades. This analysis, based on Bloom's taxonomy of cognitive domain,…

This Independent Learning Project (ILP) discusses the best practices in educational technology to improve the behavior, instruction, and learning of at-risk youth, for whom technology offers unique opportunities. Research is compiled from numerous scholarly print and online sources. A guide for teachers provides detailed strategies, software…

The purpose of this study was to determine whether students with identified behavioral needs were provided a different level of behavioral intervention based on their special education disability category verification. A second purpose of this study was to determine what caused potential differences as interpreted by individuals working in the…

Presented at the national conference for AERA (American Educational Research Association) in April 2009. The large variability of SAT taker population across states makes state-by-state comparisons of the SAT scores challenging. Using a mixture modeling approach, therefore, the current study presents a method of identifying subpopulations in terms…
