Discusses a new model of concept learning called prototype theory and describes an experiment with nursing education students in which the differential effects of prototype formation on classification were explored through an instructional program on the concept of shock. Hypotheses tested are discussed and results of pretests and posttests are…

Six children were studied from the age of 6 months to 1 year and 6 months to chart their developing comprehension vocabularies from the first to the 100th word. Observational data were used in the first instance to identify newly comprehended words and then controlled testing was carried out for each word to confirm and expand the observational…

Investigated possible priming effect of two neuropsychological tests, the Booklet Category Test (BCT) and Wisconsin Card Sorting Test (WCST). Obtained counterbalanced order effects on like-aged sample of 63 South African elementary school students (normally- achieving, low-functioning, learning-disabled). Found a significant effect of set-shifting…

Discusses catalog records for non-English books created by European booksellers and loaded into OCLC; describes a study of Italian language monographs to compare vendor records with Library of Congress and OCLC member libraries' records; and considers changes in cataloging workflow needed to edit records to include Library of Congress call numbers…

This article first describes two types of assessment (problem solving and standard treatment protocol) within a "responsiveness-to-instruction" framework to identify learning disabilities. It then specifies two necessary components (measures and classification criteria) to assess responsiveness-to-instruction, and present pertinent findings from…

Visual perception may be a developmental prerequisite to some types of social understanding. The ability to perceive social information given visual motion appears to develop early. However, children with autism have profound deficits in social cognitive function and may fail to see social motion in the same way that typically developing children…

Overt-relational and reactive-proactive subtypes of aggression have demonstrated a reliable network of relationships with social-adjustment variables and these variables have been shown to be effective predictors of future behavior problems and social maladjustment. In this study, the two measures representing these classification systems were…

Objective: To investigate the effect of a nutrition education intervention and four hours of related teaching on the nutrition concepts of a sample of 9 year-old children. Design: Prepost test design. Children's food classification concepts were assessed before and after the intervention and nutrition teaching. Setting: Year 4 class of a suburban…

This paper examines inclusive design delivery through interface design, with a particular focus on access to healthcare resources for seniors. The goal of the project was to examine how seniors are able to access drug information using two different online systems. In the existing retrieval system, pills are identified using a standard search…

This paper reports an example of a situation in which university students had to solve geometrical problems presented to them dynamically using the interactive computerized environment of the "MicroWorlds Project Builder". In the process of the problem solving, the students used ten different solution strategies. The unsuccessful…

This article examines the social nature of teachers' conceptions by showing how teachers frame the "mismatch" of students' perceived abilities and the intended school curriculum through conversational category systems. This study compares the conversations of 2 groups of high school mathematics teachers addressing the Mismatch Problem…

In this paper, the multilateral comparison method of classifying languages is described and analyzed. It is suggested that while it is espoused as a simple and reasonable approach to language classification, the method has serious flaws. "Multilateral" or "mass" comparison (MC) is not a method of genetic language…

This article considers arguments for and against the use of coding systems in classroom-based language research and touches on some relevant considerations from ethnographic and conversational analysis approaches. The four authors each explain and elaborate on their practical decision to code or not to code events or utterances at a specific point…

Cost-effectiveness analysis and cost-benefit analysis are two related yet distinct methods to help decision makers choose the best course of action from among competing alternatives. For both types of analysis, costs are computed similarly. Costs may be reduced to present value amounts for multi-year programs, and parameters may be altered to show…

The major focus of this study, it is stated, was on two comparisons of performance of four pre-school groups consisting of retarded, brain-injured, normal, and disadvantaged subjects; examining both the effects of two versus three dimensional formats on and the correlation between identification and Concept-Matching responses.
