Describes a system of categories to subdivide the gifted and talented population into the following more homogeneous subgroups: mild, moderate, high, exceptional, and extreme. Based on the metric system, each of the five levels, including the minimum threshold, selects the top 10% of the previous level. (Author/CR)

Describes the classification of minorities developed by J. Ogbu as autonomous, voluntary (immigrant), and involuntary (nonimmigrant) and explains Ogbu's cultural ecological theory of minority school performance. Implications of the theory for pedagogy are explored. The typology of minority groups is regarded as a heuristic device for analysis.…

Five experiments involving 173 college students show that people frequently do not apply the category inclusion rule when evaluating categorical arguments involving natural categories and a single nonexplainable predicate. Judgments tended to be proportional to the similarity between premise and conclusion categories. (SLD)

Evaluates the retrieval performance of an algorithm that automatically categorizes medical documents, which consists in assigning an International Code of Disease (ICD) based on well-known information retrieval techniques. Reports on experimental results that tested precision using a database of over 20,000 medical documents. (Author/LRW)

Reflects on Needham's findings on infants' object recognition and segregation. Examines the role for perceptual bias in explaining infant performance, places Needham's studies in historical perspective, and assesses their theoretical significance. Discusses the merits of positing different kinds of information sources for object segregation, and…

Three studies examined lexical categorization in 2-year- olds. Findings indicated that even with minimal opportunities to familiarize themselves with novel artifacts, children generalized their names in accordance with the objects' functions, even when they had to discover the functions on their own or when all the test objects had some…

Affirms that taking time to learn type classification, terminology, and use will be a major step in producing more effective high school newspapers. Considers that desktop publishing is both a blessing and a curse when it comes to type use. Provides type use definitions. (PA)

Two accounting strategies for classifying college or university endowment losses are compared: reduction of permanently restricted net assets and reduction of unrestricted net assets. The approaches differ in their effects on classification of net assets only when capital losses on endowment investments bring the fund below the level required in…

Presents the historical context of Diderot and how he systematized and represented mechanical arts in two dimensions in order to demonstrate how the development and packaging of technology has influenced today's delivery systems. Addresses four issues: conceptual framework, systematic analysis and description, theory and practice, and technology…

A general approach to the analysis of nominal-scale ratings is discussed that is based on a simple measurement error model for a rater's judgments. The basic measurement error model gives rise to an agreement model for the agreement matrix of two or more raters. (SLD)

Discusses using literature as a vehicle to develop mathematical understanding in a natural way. This investigation for grades three and four uses the story of "The Three Little Pigs" to motivate students to think and reason mathematically. The investigation focuses on developing the process of classification, especially an awareness of…

Defines a rubric as a set of scaled criteria, one of several methods recommended for student performance assessment. Topics include classification of performance; evaluating academic and social skills; advantages and disadvantages; types of rubrics; and rubrics for information literacy. (LRW)

Questions how secondary school students view science models. Concludes by recommending that teachers mold scientific modeling to their students, encourage the use of multiple models in science lessons, progressively introduce sophisticated models, systematically present in-class models using the Focus, Action, and Reflection (FAR) guide, and…

Discusses the definition and classification of second language learning strategies, the range of strategies used among second language learners, the importance of learning strategies, and learner strategy training. (Author/VWL)

Developed a new classification method for the logistic regression (LR) procedure for differential item functioning (DIF) based on methods used in the Simultaneous Item Bias test and conducted a simulation study to determine if the effect size measure affects the Type I error and power rates for the LR DIF procedure. Results show that inclusion of…
