This column provides an overview of the Common Core text exemplars and gives examples of ways teachers can group text exemplars and other trade books in ways that will support middle graders' understanding of complex texts. Building background by supplementing text exemplars with other titles is particularly emphasized. Suggestions for grouping…

The idea of integrating programs for the gifted into the total fabric of the school program is so central to the work of the field in the last 20 years or so that it is hard to believe that the myth of separatism is still alive and well. There is little question but that gifted programs must show a connection to the work that all of public…

In the tug-of-war between researchers and IT for supercomputing resources, a centralized approach can help both sides get more bang for their buck. As 2010 began, the University of Washington was preparing to launch its first shared high-performance computing cluster, a 1,500-node system called Hyak, dedicated to research activities. Like other…

The author of this article observes that sometimes educators are so overwhelmed by the needs of struggling learners that they believe they do not have time for the gifted, talented, high achieving, and high potential students. However, those students are just as desperate as any other students for good teachers to help them progress. Middle school…

Addresses selecting among and using the numerous quantitative job classification procedures, with a focus on the decision-making tasks and practical difficulties that confront users of each. (Author/ABB)

Using examples of data from the areas of information retrieval and of multivariate data analysis, six hierarchic clustering algorithms (single link, median, centroid, group average, complete link, Wards's) are examined and evaluated by using three proposed coefficients of hierarchic structure. Nine references are cited. (EJS)

Addresses the application of automatic classification methods to the problems associated with computerized document retrieval. Different kinds of classifications are described, and both document and term clustering methods are discussed. References and notes are provided. (Author/JD)

Discusses the problem of processing fuzzy queries in databases and information retrieval systems and presents a prototype of a fuzzy query processing system for databases that is based on data clustering and uses Pascal programing language. Clustering schemes are explained, and the system architecture that uses natural language is described. (14…

Gary and Tall (2001) recently suggested that mathematics can be split up into "three worlds": the embodied, the proceptual and the axiomatic. They claim that objects from each of these worlds are formed, and reasoned about, in significantly different ways. During the course of this article the author considers the three world's theory…

Presents system for automatic handling of ordered sets, states based on these sets, and differing points of view regarding Universe of Discourse. Aspects are represented by new logical "overlap" function with examples taken from Ranganathan's horse and carriage parable and several books involving four main concepts (history, geography,…

Describes results of a citation analysis of 209 articles from the "Journal of the American Society for Information Science" (JASIS) that was conducted to determine the intellectual base and the research front. Topics discussed include citation-based mapping techniques, including bibliographic coupling and cocitation analysis; and…

A classification of propositions (consisting of a verb and its arguments) is presented with a stipulation of the properties of each type, and clarification is given for how the classfication and the properties function in the interaction between propositions and Japanese aspectual auxiliary verbs. The different types of verbs include: (1) state…

Many different systems have been developed for classifying occupations. A few of the major systems are described here, along with an idea of the kind of information collected and published by the agency using the system. (Author/SSH)

Describes methods for effecting the partition of information systems consisting of many components and interconnections into subsystems which are later made to interface with one another achieving an overall system. Clustering algorithms for the specific case of information systems are obtained and exemplified. Twenty-seven references are…

Argues that the account of coordination of unlike categories ought to be unified with the account of feature neutralization under phonological identity. Further argues that this unified account ought not be couched in terms of string of features, but rather in terms of the logic of categories. Study concludes with a discussion of the interactions…
