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…

This article commences with an excerpt from a memo entitled "Problems in Assessment of LD Children," recently found when the U.S. Office of Special Education Programs (OSEP) relocated their offices. The letter was written by then junior staffer Lou Danielson to a university professor. Although Danielson's letter was written in 1977, 27…

This study used electropalatography (EPG) to identify place of articulation for lingual plosive targets /t/, /d/, /k/ and /g/ in the speech of 15 school age children with repaired cleft palate. Perceptual judgements indicated that all children had correct velar placement for /k/, /g/ targets, but /t/, /d/ targets were produced as errors involving…

Using the Decoding the Disciplines model, faculty who are deeply ingrained in their disciplinary research answer a series of questions to understand how students think and learn in their field. The cross-disciplinary nature of the process clarifies the thinking for each discipline. (Contains 1 figure.)

Reference set computation -- the construction of a (global) comparison set to determine whether a given derivation is appropriate in context -- comes with a processing cost. I argue that this cost is directly visible at the acquisition stage: In those linguistic areas in which it has been independently established that such computation is indeed…

There has been an interest in the World Health Organization's framework of functioning and disability by those in communication disorders since the original 1980 International Classification of Impairments, Disabilities, and Handicaps (ICIDH). In 2001, WHO published the substantially revised International Classification of Functioning, Disability,…
