Five experiments used a categorization habituation-of-looking paradigm to investigate infants' categorization of animals and vehicles based on static versus dynamic attributes of stimuli (color images versus dynamic point-light displays). Findings showed that 6-month-olds categorize animals and vehicles based on static and dynamic information, and…

Compares two different methods of educational instruction, both addressing the improvement of pupils in bird species identification skills. Uses hands-on and group-based learning styles with (stuffed) taxidermy specimens and teacher-based slide presentations. Reports an increase in knowledge with both instructional methods but different learning…

This article provides the American Psychiatric Association's definition of attention deficit disorder (ADD) and then gives an overview of ADD by considering the three types of ADD, the developmental impact of ADD, factors contributing to ADD, identification and assessment of students with ADD (emphasizing multimethod and consideration of…

Reports results from a national study into the perceived variation reported by health information managers related to the relevance-efficiency trade-offs of information classification across regions and practice settings. Findings suggest that due to major regional variation, stringent national information standards may be counterproductive for…

Presents a game of classifying objects according to their attributes using a three-set Venn diagram, then analyzing the classification of the objects to determine their accuracy. Requires students to capture opponents' game pieces (tangrams) by making mathematical arguments that identify misplaced pieces. (YDS)

Three experiments introduced 2- and 3-year-olds to novel adjectives either using full noun phrases and describing multiple familiar objects sharing a salient property or describing nouns of vague reference. Found that both groups mapped novel adjectives onto object properties when given taxonomically specific nouns with rich referential and…

Three studies investigated whether anatomical measures could separate phonologically based reading disability (PD) from non-phonologically based learning disabilities such as specific language impairments (SLI) in children. Results indicate that PD and SLI are qualitatively different disorders associated with anatomical deviations in opposite…

Discusses course material organization for Web-based courses that rely on the instructor's mental models of organization and describes a study that was conducted to determine if a discrepancy exists between instructor organization and student expectations of where to find materials. Highlights include a theoretical framework; categorization; and…

A study investigated whether higher prevalence of reading disabilities among boys is related to gender bias in the prediction of reading from IQ. Data from 1,139 New Zealand children (collected during ages 5-13) indicate a significant intercept bias. Boys' predicted reading scores were systematically overestimated, thereby inflating IQ-reading…

Five young adult females with mild mental retardation were given match-to-sample training to develop four classes of equivalent stimuli. All subjects demonstrated development of all possible equivalence classes involving these stimuli. For four of five subjects, the classes that included auditory stimuli developed more rapidly than those that did…

The study evaluated the utility of Kaufman-Assessment Battery for Children (K-ABC) subtests in differentiating learning-disabled children from students with other handicapping conditions, and compared K-ABC subtests with Wechsler Intelligence Scale for Children-Revised subtests. Results showed that subtest scores did not enhance differential…

Three types of instructional games (learning, practice, and creative) are distinguished and discussed, and their place in the second language classroom is considered. It is emphasized that instructional games should complement, not repeat, classroom instruction. (MSE)

Examines how the term "Middle Arabic" has been used insufficiently, inappropriately, and in inconsistent manners, and also defines Middle Arabic by historical period and linguistic level. An analysis is made of Middle Arabic's multiglossic complexity and the unique structure of Middle Arabic compared to Old and Modern Arabic. (23 references) (GLR)

Outlines an approach to the automatic construction of a knowledge base resulting in a system that is able in each phase of its construction to acquire domain knowledge from all new information that it is building, particularly index terms. Topics covered include production rules, the use of semantic networks, and user interfaces. (32 references)…

Describes activities for developing pattern recognition and classification using worksheets. The objectives, directions, extensions, and bibliography are provided for each activity. (YP)
