Twenty-three single-subject studies aimed at improving the writing achievement of students identified as having a learning disability were analyzed meta-analytically. The effect size phi was used to compare the writing strategies. The dependent measures used to assess the efficacy of the interventions were also coded and reviewed. Results suggest…

To provide timely and effective supports for students reading below grade level, schools require methods for quickly and accurately identifying those students in need. One method for identifying those students is through universal screening. Assessments such as oral reading fluency (ORF) and Maze reading comprehension are commonly used as…

Concerns about the ability-achievement discrepancy method for specific learning disability (SLD) determination led to alternative research-based methods, such as failure to respond to intervention. Neither of these "regulatory" methods address the "statutory" SLD definition, which explicitly includes a deficit in "basic…

The purpose of this article is to examine models designed for the determination of a learning disability and compare them to specific criteria to determine whether the given diagnostic process is ecological in nature. The traditional child-centered deficit model (CCD), Relative Achievement Discrepancy model (RAD), and Responsiveness to…

This study suggests that the Peabody Picture Vocabulary Test and the Slosson Intelligence Test measure different and limited aspects of a child's ability and are only rough estimates of his/her capability of what is generally termed intelligence. Scores from either should be interpreted with care and in light of other information about a child.…

Assessed the degree of comparability between the tests over time for two samples of referred adolescents of borderline intelligence. Results indicated that the Wechsler Adult Intelligence Scale-Revised significantly overestimated the Wechsler Intelligence Scale for Children-Revised by three to five points. Differences were most marked at the lower…

Learning disabled college students (N=16) were tested to compare the Wide Range Achievement Test (WRAT) with the Peabody Individual Achievement Test (PIAT). Significantly different scores are derived when WRAT norms are compared with PIAT norms, indicating that the tests are not interchangeable instruments for academic achievement. (RC)

This study compared the three scales of the WISC and the WISC-R for degree of intercorrelation. Results included significant correlations in all cases, no systematic changes in variance, and significantly lower IQs on the WISC-R for all children in the sample, except the EMRs. (Author)

Results show that Peabody Picture Vocabulary Test (PPVT) IQs are not interchangeable with Wechsler Intelligence Scale for Children-Revised (WISC-R) IQs in a sample of reading disabled children. The PPVT yielded higher IQs on the average than did the WISC-R, supporting results obtained with learning disabled students. (Author/BEF)

Compares the performance of learning disabled students on the WISC-R and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery. This study finds that learning disabled subjects performed more poorly on the Tests of Cognitive Abilities than on the WISC-R. (Author)

Results of the Kaufman Assessment Battery for Children (K-ABC) and Bender-Gestalt Test were compared for a sample of learning disabled children that included 24 blacks and 24 whites; mean age 9 years. A significant correlation coefficient was found between the K-ABC Simultaneous Scale and the Bender-Gestalt Test error score. Implications of these…

Paper explores the use of an intelligence test in a southwestern university. Honor students performed significantly better than the average freshmen and the developmental/remedial students. Results suggest that developmental students lack specific cognitive abilities as well as some higher order thinking skills. Implications are discussed. (RJM)

An operational index of discrepancy to assist in identifying learning disabilities was derived using the Full Scale IQ, Wechsler Intelligence Scale for Children, and relevant subtest scores on the Peabody Individual Achievement Test. Considerable caution should be exercised when classifying children, especially females, as learning disabled.…

WISC-R (Wechsler Intelligence Scale in Children-Revised) Verbal and Performance scores were correlated with WRAT-R Wide Range Achievement Test-Revised scores. The verbal score was found to predict reading, spelling, and arithmetic. The performance score did not add significantly to the predictions. Results were consistent with earlier studies.…

Compared nonhandicapped (NH), educationally disadvantaged (ED), and learning disabled (LD) Navajo children on intellectual dimensions measured by the WISC-R. The ED and LD group means were similar on verbal measures, but the LD group scores were lower than ED group scores on performance measures. (Author/RC)
