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)

A system of medical classification based on the dimensions of body system, etiology, and stage of disease was evaluated by classifying the content of one specialty board's examinations. This classification system may allow a board to define the content of its examinations, monitor requirements for certification, and communicate its standards.…

Psychoeducational assessment variables for 119 referred high-school students were subjected to discriminant function analysis. Variables predictive of learning-disability classification were spelling, intelligence quotient, and the interview question, "Do you think going into a special class/program would help you?." (MSE)

Describes exercises in which tabs from aluminum beverage cans are used to introduce principles of classification, biostratigraphy, and evolution. Provides diagrams which represent dorsal and ventral views of species and a table which graphs units of time in relation to species duration. (RT)

Summarizes responses from 40 states and 5 provinces to a survey of their space recommendations for public elementary and secondary schools. (MLF)

Discusses and defines immediate and delayed feedback as they apply to computer-assisted instruction and testing. A research classification matrix is presented to provide a framework for classifying existing feedback studies and to guide future research, and a sample bibliography classified according to the matrix is given. (31 references) (LRW)

Describes differences in the socialization setting provided by all-boy and all-girl play groups, and explores possible reasons for children's tendency to congregate in same-sex groups. Considers three classes of possible explanatory processes: biological factors, socialization pressures from adults, and gender cognitions. (RH)

Attempted to classify convicted rapists, child molesters, and three different control groups, based on information from various assessment sources. Results indicated that behavioral measures combined with life history data could accurately classify subjects well above chance rates. Fairly accurate classification was obtained for three of five…

A multidimensional model of mental retardation is proposed, based on medical, behavioral, and social dimensions. The model's theoretical underpinning emphasizes that an individual might be retarded in one or a combination of senses. The model introduces a conception of socially constructed retardation and suggests methods for operationalizing and…
