This paper reviews some of the cognitive and linguistic functions which develop during the period of concrete operational thought (ages 4-9) as defined in Piaget's developmental theory. Discussion centers on the formation of classes and relations and the development of the language associated with these operations. Also discussed are conservation…

The focus of this paper is on groups of teachers classified according to self-reported national and/or racial heritage. The problem studied was simply notation of similarities and differences among mean scores of groups of in-service teachers in the U.S.A. when the teachers were so classified. Ss were over 3,000 in-service teachers from the 50…

Reading comprehension questions selected from readers, teacher manuals, and workbooks of three current, widely used and representative basal reading series were analyzed according to the Barrett Taxonomy to determine cognitive objectives. The taxonomy has five major divisions and thirty-three levels within, claimed to be cumulative and sequenced…

An attempt to locate, review, classify, and abstract a more extensive set of measurement instruments and tests relevant to education and care programs for children from birth to age eight was made. Publishers' catalogs, test review, journals and other measurement documents have been examined to obtain a list. After extensive examination of…

Naming tasks were used in two studies to test for conceptual organization in young children by comparing the latencies for naming objects in primed vs. non-primed conditions. In the primed condition, a taxonomic category was primed by prior activation of a coordinate member of the same category. In Study 1, 54 kindergarten children were randomly…

This study attempted to determine whether a combination of seriation and classification training would produce more general intellectual gains. (Author/SB)

An approach to teaching grammar concepts treats conceptualization as a process of sensitization, consisting of three stages: motivating the student to learn the concept, presenting the operating concept and the grammatical category in question, and consolidating and enriching the concept in the student's mind.

This study evaluated the diagnostic validity of a task measuring abstract categorization ability in learning disabled (LD) and non-LD children. Data showed that the component of abstract category knowledge that best disciminates LD children from non-LD, is the knowledge of how members of abstract categories differ from each other. (Author/JAZ)

Details a study in which high school students were introduced to a categorization strategy for vocabulary terms related to literary analysis. Concludes that the strategy was a worthwhile addition to the traditional Socratic approach to literary analysis. (FL)

Variations in sorts of rural Mexican-Spanish "have" verbs were analyzed using two approaches: one which measures subject differences from a standard categorization, and another which directly compares pairs of individual subject's sorts. "The second approach revealed a consistent structure for a subset of the subjects not revealed…

Analyzes key problems associated with representation of the intellectual content of digital objects. Presents a framework for analysis based on Peirce's notion of unlimited semiosis. This analysis is based on the assumption that every element in the subject indexing process could be regarded a sign. (AEF)

This article considers whether Asperger syndrome (AS) should necessarily be viewed as a disability or as a difference. It concludes that "difference" is a more neutral and fair description. A model (the emphasizing-systemizing model) is summarized that attempts to define in what way individuals with AS are different. (Contains references.)…

Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…

Performance on a battery of tests of vocabulary words by 72 college students was compared as a function of whether the prior instruction involved presenting material in an organized or scrambled fashion. Organizing vocabulary words during study facilitated performance in categorizing, processing for understanding, or producing a word. (SLD)

Using cluster analysis, a study empirically divided 54 children with attention-deficit/hyperactivity disorder (ADHD) based on their Full Scale IQ and reading ability. Clusters had different patterns of cognitive, behavioral, and neurochemical functions, as determined by discrepancies in Verbal-Performance IQ, academic achievement, parent…
