Raises questions regarding the classification system Darwin and Gray offer for phrasal verbs on the basis of utility in the classroom. Darwin and Gray clarify the purpose of their classification system and provide additional corpus-based data. (Author/VWL)

A study investigated categorization strategy training effects on the abilities of five children with autism to accurately complete uni-, bi-, and tri-dimensional sorting. Five children showed strategy acquisition and generalization during training, four showed strategy maintenance 4 months later, and one showed uni- and bi- dimensional strategy…

Provides a brief background of the Biological Abstracts' title index, "Biological Abstracts' Subject in Context" (BASIC) "Stop List," or compilation of nonsignificant words that were going to be automatically stopped from printing. Notes that the Stop List provided an improvement over the raw computer output of titles while…

Provides examples of current work in social science disciplines that address the policy research argument that understanding the impact of changes in human numbers on social and cultural life requires moving beyond current standards of empirical categories. Discusses enumeration categories suggested by the United Nations. (SLD)

Discusses knowledge management that seeks to minimize information overload in order to enhance performance. Highlights include the differences between data, information, and knowledge; the relationship between learning, knowledge, and performance; the use of focus groups; documenting results; and knowledge classification. (LRW)

Used classification and seriation games over 4 months to teach the oddity principle and insertion into a series to Head Start 4-year-olds during free play. A comparison group participated in free play without the teacher-directed classification and seriation games. At the conclusion, intervention students were significantly better than comparison…

Describes an interactive computer program that provides students with a means for learning classification concepts in the psychology classroom; if computers are not available, clip art can be utilized to study classification. Maintains that the program encourages students to see the importance of modifying any classification system as new data…

Investigated patterns of teachers' interaction behaviors in early childhood classrooms. Identified four homogenous interaction clusters. Found cluster differences for teachers' education; teachers' sensitivity; classroom quality; group child engagement; and center licensing level. (Author/HTH)

Provides and illustrates a method to compute the expected number of misclassifications of examinees using three-parameter item response theory and two state classifications (mastery or nonmastery). The method uses the standard error and the expected examinee ability distribution. (SLD)

Investigated 3-month-olds' categorization of animals and vehicles based on static and dynamic attributes. Found that regardless of viewing static or dynamic displays, infants showed habituation to varying exemplars from the same category, dishabituated to an exemplar from a novel category, and showed a novelty preference for a novel-category…

Outlines a proposed classification system for 2-year institutions that is based on cluster analysis and could provide a framework for policy-relevant research. Public institutions, not-for-profit institutions, and private-for-profit institutions are further divided to yield a seven-category classification system. (SLD)

Students prefer to classify creatures along the criteria of habitat and locomotion (method of movement). Discusses the educational consequences for biology instruction, particularly with regard to biological taxonomy, biodiversity, and evolution. (Contains 33 references.) (Author/YDS)

Points out the difficulties students have when they are expected to learn functional groups, which are frameworks for chemical and physical properties of molecules. Presents a classification key for functional groups categorized by 10 common functional groups. (YDS)

Increases in regulatory oversight of animal research require verification of effects of standard practices. There are no formal guidelines for establishing free-feeding weights in adult pigeons. In the present study, pigeons were obtained from a commercial supplier, weighed upon arrival, and then held in quarantine for 7 days with free access to…

This article presents a systematic ethnographic study of emic ethnic classification in Puerto Rico, including a replication and extension of Marvin Harris's (1970) seminal study in Brazil. I address three questions: (1) what are the core emic categories of color? (2) what dimensions of semantic structure organize this cultural domain? and (3) is…
