Twenty-five white children in the bright normal range of intelligence were administered both the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scale for Children-Revised (WISC-R). The mean values for the normally obtained mental age (MA) and adjusted MA were then compared to the mean WISC-R test age (TA). The normally obtained Stanford-Binet MA and the WISC-R TA values were nearly identical. However, the adjusted values for the Stanford-Binet MA were found to be significantly lower (p<.05) than the WISC-R TA. The findings failed to support the common practice of computing an adjusted MA score. 相似文献

The WISC-R and the Fourth Edition of the Stanford-Binet (SB: FE) were compared in the identification and assessment of 48 intellectually gifted students in the primary and secondary grades. While only a 3.2-point difference between the mean SB: FE Composite score and the mean WISC-R Full Scale score was found, (r = .393, p. ⩽ .01), the t test between the two scores was significant (t = 2.30, p ⩽ .05). Correlations between the three scales of the WISC-R and the SB: FE four broad area and Composite scores ranged from −.219 (SB: FE Abstract/Visual Reasoning with WISC-R Verbal) to .599 (SB: FE Short-Term Memory with WISC-R Full Scale). Within the correlational matrix, only 5 of the 15 correlations were significant. Both the SB: FE Abstract/Visual Reasoning and Quantitative Reasoning Area scores had no significant correlations with any of the WISC-R scores. 相似文献

The Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) are two tests that are often used in the assessment process for special education referrals. Sex differences apparent in these tests were examined in a sample of Arkansas school children who were first-time referrals for a psychological evaluation. The subjects' PPVT-R standard scores, WISC-R IQ scores, and WISC-R subtest scores were divided into groups according to one-year intervals from ages 6 through 16. A separate 2 × 11 (subjects' sex x subjects' age) analysis of variance was performed for each dependent variable. Results indicated significant sex differences among WISC-R Full Scale, Verbal, and Performance IQs and PPVT-R standard scores (p < .01). Several WISC-R subtests also revealed significant sex differences. Further significant sex differences were indicated at several age groups on each dependent variable, with males consistently scoring higher than females on 87%. of the dependent measures excluding the WISC-R subtest Coding, on which females scored higher. Implications concerning the referral process are discussed. 相似文献

This study investigated the performance of 166 special education students who had been administered the WISC-R and approximately 3 years later the WISC-III. The sample ranged in age from 6.0 to 16.6 years. The scores were analyzed using Pearson product moment correlation coefficients and t tests of the differences between means for related samples. The results indicated that there was a significant, positive correlation among global scales (p < .001). This finding suggests that the WISC-R and the WISC-III IQ scores measure similar abilities. Analysis of mean IQ score differences revealed significant differences in the WISC-R and the WISC-III IQ scores, with the WISC-III global scores being lower. Implications for the evaluation of students for special education are discussed, with special emphasis on the role and function of the psychologist practicing in the schools. © 1996 John Wiley & Sons, Inc. 相似文献

The K-BIT and the WISC-R were administered in counterbalanced order to 35 referred students. Although the K-BIT IQ Composite correlated significantly with the WISC-R Full Scale IQ scores (r=.81), the mean scores differed significantly (difference = 6.2 points; p<.001). The results provide moderate support for the K-BIT as a screening instrument when the WISC-R is the follow-up or comprehensive measure of intelligence. 相似文献

Scores from Koppitz' scoring system for the Bender-Gestalt and Beery's Developmental Test of Visual-Motor Integration for a group of 86 elementary students referred for psychoeducational evaluation were correlated with Wide Range Achievement Test scores, controlling for WISC-R IQ. Although zero-order correlations of the visual-motor measures with achievement were of moderate magnitude (.33 to.48) and were all statistically significant (p<.01), first-order partial correlations were of lower magnitude (.13 to.22) and half failed to reach statistical significance (p>.05). It was suggested that visual-motor ability may not offer a unique contribution to the prediction of achievement. 相似文献

The present study evaluated the technical aspects of three WISC-R administrations of five psychology graduate students using the WISC-R Administration Observational Checklist (WAOC). The observations also were used as a means of evaluating interrater agreement on the WAOC. Based on a total of 15 observations of two raters, Cohen's x was calculated for 29 of the measures on the checklist. The x values for 24 of these measures were significant (p < .01). Overall scores on the WAOC indicated that students performed significantly better on the second than on the first observation. Their level of performance was maintained, but was not significantly improved, at the time of a third observation made during the second semester. Error patterns were similar to those found by Fantuzzo, Sisemore, and Spradlin (1983), using the Criteria for Competent WISC-R Administration (CCWA). 相似文献

So as to compare predicted achievement based upon WISC-R IQs and observed achievement by the WRAT standard scores, both instruments were administered by the same school psychologist to 282 urban students referred for psychological evaluation. The correlations obtained, even on this nonrandom population, were substantial, significant (p < .001), and should be useful to school psychologists in statistically relating intelligence test scores to school achievement. 相似文献

So as to compare the results of the WISC and WISC-R, both instruments were administered to 58 children randomly selected from a school population of 583. All administration and scoring was performed by the same psychologist, with a two-month interval separating the administrations for each child. All IQs were significantly higher (p <.01) on the WISC, with the Performance difference being greater than the verbal difference. Also, 8 of the 10 required subtest scaled scores were significantly greater (p <.05) on the older instrument. Regression equations were obtained to predict WISC-R IQs from WISC scores. 相似文献

The Woodcock Language Proficiency Battery (WLPB) was administered to 18 learning-disabled adolescents from a culturally variant population in rural southern Louisiana and to a matching group of normal achievers. ANOVA results revealed that group status (learning-disabled vs. normally achieving) had a significant effect on cluster scores (Oral Language, Reading, and Written Language), p < .001. Significant effects for cluster scores were not discovered; however, the significant interaction (p < .05) between subjects and cluster scores was determined to be the result of group differences on all cluster scores. Kolmogorov-Smirnov Z-test results indicated that all WLPB cluster scores for the learning-disabled group were significantly lower (p < .001) than the test's means for each of these clusters; but, for the achieving group, only the Oral Language Cluster mean was significantly lower than the WLPB mean, p < .001. Additional t-test investigation revealed that the learning-disabled group means were significantly lower than the achieving group means on all subtests except for Picture Vocabulary. A modified contrastive linguistic analysis did not uncover the existence of test bias for semantics when error responses were evaluated. The results of this study suggest that the WLPB may be a useful tool for culturally diverse students when interpretation is based on a community norm perspective. 相似文献

Raw scores on the 16 K-ABC subtests and the total raw scores on the sequential and simultaneous processing scales and the achievement scale were correlated with age in months for two separate samples, each subdivided by race and sex: the K-ABC standardization sample (N = 2000) and an additional group of blacks and whites tested during the development of the K-ABC sociocultural norms (N = 615). Within each sample, the highest and lowest correlations from all race/sex groups were contrasted across all K-ABC subtests and scales. All correlations between age and raw scores were statistically significant (p ⩽ .05). No significant differences occurred in the magnitude of these relationships as a function of race/sex grouping, supporting the construct validity of the K-ABC as a developmental measure of children's aptitude and achievement for blacks, whites, Hispanics, males, and females. 相似文献

To determine the relationship between relative age and achievement in middle school, standardized math and reading scores for a sample of middle-class, suburban middle school students (N = 933) were examined. Analysis of variance revealed a significant difference among relative age groups in only one area, sixth-grade reading, F(2, 146) = 3.1, p < .05. There was no main effect for gender and no interaction between age and gender in sixth, seventh, or eighth grade. When the birth month of students who had repeated one or more grades was examined, it was revealed that a large percentage of these students would have been the youngest in the class when beginning school. Results suggest that a relationship between relative age and achievement may exist in the lower grades but diminishes or disappears by seventh or eighth grade because of the retention of a larger proportion of the youngest children. 相似文献

Each year thousands of children are evaluated or reevaluated utilizing the current edition of the Wechsler Intelligence Scale to determine their eligibility for gifted programs. The Wechsler Intelligence Scale for Children-III (1991) is new enough that only limited research is available on how it compares to the previously used Wechsler Intelligence Scale for Children-Revised (1974). The purpose of this study was to determine the comparability between the previously dominant intelligence scale, the WISC-R, and the revised WISC-III with gifted children. The results of this study indicate that the latest revision (WISC-III) and the earlier version (WISC-R) produce remarkably similar scale and subtest scores when administered under clinical conditions to gifted children. All 51 children determined eligible through the administration of one of these two Wechsler tests would have been eligible for services had the other test been administered. The Verbal and Performance scale IQ scores were within two points of each other across the two test administrations, while only a one-point difference existed between the Full Scale IQ scores. The Arithmetic, Comprehension, and Object Assembly subtest scores were in high agreement across the two administrations (p<.01). The level of agreement between some subtests across the two administrations suggests that clinical judgment is just as important as scores in considering who is eligible for gifted programs. 相似文献

The WISC and WISC-R protocols of 94 special education students (51 white males, 5 black males, 30 white females, and 8 black females) who tested in the mildly retarded and borderline range of abilities (IQs of 50–78) were examined. Their test performance was then followed longitudinally for two additional WISC and WISC-R assessments. Mean age of subjects was 8 years at Test 1, 10.75 years at Test 2, and 14.9 years at Test 3. As predicted, subjects had lower IQ equivalent scores on Bannatyne's Sequencing Ability category than their IQ equivalent scores on the Verbal Comprehension or Perceptual Organization factors of the WISC and WISC-R for all three testings. Results were interpreted as supporting the notion that mildly retarded children and learning disabled children have qualitatively similar learning patterns. 相似文献

The purpose of this study was to determine the degree of comparability between the WISC and the WISC-R over time. Hypotheses were tested using a sample of 276 mildly mentally handicapped children enrolled in special education classes who had received a WISC (Trial 1) and a WISC or WISC-R (Trial 2) after an interval of approximately three years. The sample was grouped on the basis of test administered in Trial 2. Group I contained those children who received the WISC on Trial 2 and included 183 children, of whom 121 were males and 62 were females. Mean age at time of initial testing was 8–10; mean age at second testing was 11–8. Group II was composed of 93 children who had been posttested on the WISC-R and included 72 males and 21 females. Mean age at initial testing was 9–5; mean age at posttest was 13–0. The study was conducted in five school districts and one county department of education. Verbal IQ, Performance IQ, and Full Scale IQ for both instruments administered were transcribed from the special education folders of the children. The design used to test hypotheses was repeated measures analysis of variance. Data analysis resulted in rejection of the hypotheses that the WISC-R yields mean Verbal, Performance, and Full Scale IQ scores greater than or equal to the corresponding mean IQ scores of the WISC. It was concluded that the WISC-R may unfairly penalize special education children who are reevaluated with this instrument. Fluctuations in IQ scores due to the instrument of measurement must be recognized, and appropriate action should be taken to insure that children are evaluated for special class placement on comparable bases. 相似文献

The present study was undertaken to examine scatter analysis and Kaufman regroupings of WISC-R scores. Thirty-one non-learning-disabled children (NLD) and 29 learning-disabled children (LD) determined by individual IQ and achievement scores served as subjects. Scatter indices were computed within the Verbal and Performance subtests as well as between the Verbal and Performance IQ scales. Also, the regrouping categories proposed by Kaufman (1979) were examined. A significant difference in Verbal and Performance IQs was found between the LD and NLD group. Significantly more students in the LD group exhibited the Kaufman regrouping pattern than in the NLD group (p < .01). These results suggest that Kaufman regroupings and Verbal-Performance scatter analysis may be used to assist in diagnosing LD children. 相似文献

PPVT and WISC-R scores were compared for 259 students ranging in age from 6 to 16. In descending order, Pearson product correlations ranked best for the total sample, emotionally disabled, regular class, mentally retarded, and learning disabled. In all groups, the PPVT overestimated ability and was significantly different from the WISC-R scores as measured by correlated t-tests. 相似文献

The relationship between the WISC-R and WAIS-R was studied in a sample of 30 special education children (22 male and 8 female). Children were administered the WISC-R at an average age of 13.85 years and the WAIS-R at an average age of 17.52 years. ANOVAs indicated that the two tests yielded Verbal, Performance, and Full Scale IQS that were not significantly different. For example, the mean Full Scale IQ was 81.13 for the WISC-R and 82.70 for the WAIS-R. Product-moment correlations also were highly significant, with rs ranging from .76 to .86 for the three scales. The results suggest that, for children of limited intelligence, the WISC-R and WAIS-R provide comparable IQs over a four-year time period. 相似文献

Background:?The increasing numbers of teaching assistants (TAs) and their widening role in English primary classrooms is part of wider international developments. Several large quantitative studies have been influential in shaping debate, but little qualitative research exists on TAs and the content of their activity in the key area of mathematics. Purpose:?The article addresses the question: How do TAs in primary schools perceive their role in daily mathematics lessons? Sample:?Twenty-four TAs employed in English primary schools participated in the study. Their experience ranged from 2 to 20 years. Two were men; the rest were women. Design and methods:?Interviews were undertaken in the spring and summer of 2011, transcribed and coded using Glaser and Strauss’ recommended method (B. Glaser and A. Strauss, 1967, The discovery of Grounded Theory: Strategies for qualitative research; Chicago, IL: Aldine Publishing Company). A typology of TA activity was created and used together with other cross-cutting factors to ascertain what TAs did in general and, specifically, in mathematics teaching. Results:?The results show that previous pictures generated from large-scale quantitative studies of TAs working with children seen as having the greatest difficulty in mathematics are essentially (though not universally) correct. However, they may be internally differentiated to a greater extent than previously envisaged. Conclusion:?The range of TA activities in mathematics classrooms is considerably wider than previously thought; professional development for TAs and teachers needs to take account of this. 相似文献

This study investigated sex differences on the WISC-R subtests for retarded males and females who were matched in terms of WISC-R Full Scale IQs. The sample consisted of 126 children and youth (63 females, 63 males) ranging in chronological age from 7–3 to 8–3, with a mean CA of 7–8. Each subject was matched in terms of Full Scale IQ score. A 2 × 10 analysis of variance with repeated measures on a single factor was used to analyze the data. Students' T and Fisher's F ratios were calculated, and differences between subtest means were analyzed by Newman-Keuls test for sample effects. Evidence from the investigation indicated that a significant interaction effect existed between sex and subtest scores. 相似文献
