Twenty-eight third graders were administered the Peabody Individual Achievement Test (PIAT) during the middle third of their third-grade year. Their scores on all subtests of the PIAT were correlated with their Total scores obtained on the Screening Test of Academic Readiness (STAR), which had been administered to them prior to their kindergarten year of school. Results show that the STAR is a useful instrument for predicting third-grade achievement. 相似文献

The overlap of words specifically taught in reading textbooks with the contents of standardized reading achievement tests may be a source of bias that is frequently overlooked in psychoeducational assessments. This study compares the standardized achievement test performance of 62 second graders receiving instruction in two different reading curricula (Open Court and Houghton-Mifflin) to determine whether either curriculum generates different quantitative estimates of reading achievement. Reading subtest scores derived from the Kaufman Test of Educational Achievement-Brief Form (K-TEA), the Wide Range Achievement Test-Revised (WRAT-R), and the Reading Recognition and Reading Comprehension subtests from the Peabody Individual Achievement Test (PIAT) were examined. Grade level equivalents and scaled scores from the California Achievement Test (CAT) were also examined. Three Curriculum × Test repeated measures ANOVAs were conducted using grade level scores (2×7), standard scores (2×4), and CAT scaled scores (2 × 5) as dependent measures. A significant Curriculum × Test interaction was identified, suggesting differences among tests in estimates of reading ability as a function of the reading program. 相似文献

To investigate the concurrent validity of the Peabody Individual Achievement Test and the KeyMath Diagnostic Arithmetic Test, both instruments were administered to 171 adolescents. Math scores on the Peabody Individual Achievement Test were correlated with all scores on the KeyMath Diagnostic Arithmetic Test. Partial correlation coefficients were computed according to age, sex, race, IQ, and total group. The presence of relatively high and positive partial correlations between the scores supported the concurrent validity of the instruments. 相似文献

Although there have been a number of studies that compared the test results of the Wide Range Achievement Test (WRAT) and the Peabody Individual Achievement Test (PIAT), none had been accomplished with a group of college-aged learning disabled students. Indeed, few researchers had investigated populations over 16 years of age, and none had compared grade scores and standard scores with appropriate subtest scores as derived from these two instruments. With the recent emphasis on postsecondary education for the learning disabled, it is deemed critical that researchers should develop a data base for study of this population. The current research demonstrated that although both tests purport to measure academic achievement in reading, spelling, and arthmetic, in reality, significantly different scores are derived when WRAT (1965, 1978) norms are compared to PIAT (1970) norms as stated in grade scores and standard scores. These significant differences in the grade and standard scores clearly indicate that the WRAT and the PIAT, particularly in regard to arthmetic and to a lesser degree to reading, are not interchangeable instruments of academic achievement. 相似文献

Correlations between the WISC-R Full, Verbal, Performance, and Freedom from Distractibility Scale IQs, WISC-R subtest scaled scores, and Wide Range Achievement Test Reading, Spelling, and Arithmetic standard scores were computed for a sample of 114 children (64 boys, 50 girls), aged 6 to 16 years, who were referred for psychological evaluation because of academic or learning difficulties. The Full Scale IQ, Verbal Scale IQ, and Freedom from Distractibility IQ correlated moderately with the three achievement area standard scores (rs of .48 to .59). However, the Performance Scale IQ correlated minimally with reading and spelling scores (rs of .26 and .27), but moderately with arithmetic scores (r = .40). The results support the concurrent validity of the WISC-R. 相似文献

Word reading and math computation scores were predicted from Wechsler Abbreviated Scale of Intelligence Full Scale IQ, 10 neuropsychological tests, and parent attention deficit hyperactivity disorder (ADHD) ratings in 214 general population elementary school children. IQ was the best single predictor of achievement. In addition, Digit Span contributed significantly to reading prediction, and the Developmental Test of Visual-Motor Integration (VMI) and Coding contributed to math prediction. The remaining neuropsychological test scores did not significantly improve achievement prediction. Exploratory factor analysis yielded a general ability factor (comprising the four IQ subtests, Digit Span, VMI, reading, and math), five factors made up solely of subtests from single measures (Wisconsin Card Sorting Test, Stroop Color and Word Test, Gordon Diagnostic System, California Verbal Learning Test, and ADHD ratings), a factor consisting of Grooved Pegboard Test and Coding, and a factor consisting of Symbol Search and Animal Naming Test. 相似文献

The effects that item order and basal and ceiling rules have on test means, variances, and internal consistency estimates for the PIAT mathematics and reading recognition subtests were examined. Seven items on the math subtest and one item on the reading recognition subtest were significantly easier or harder than their test placement indicated. The use of basal and ceiling rules had a pronounced effect on the means, variances, and reliabilities on the multiple choice math subtest, while the rules' effects on the reading recognition subtests were minor. Item order also affected scores on the math subtest. 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 appropriateness of the starting points for PIAT subtests as suggested by the test authors was investigated. For a sample of 113 subjects with an average WISC-R Full Scale IQ of 98, there was an average difference of nearly 8 points between the suggested starting points for the Mathematics subtest and the actual basals. The difference between suggested starting points and basals for the other subtests ranged from 8 to 12 points. It was suggested that the PIAT user start each subtest approximately 8 items below that suggested by the Manual. 相似文献

The ability of a battery of kindergarten screening measures to predict educationally relevant criteria was investigated. Subtest scores on The Vane Test of Language and The Vane Kindergarten Test administered at the beginning of kindergarten were examined and compared to the Metropolitan Achievement Test scores in reading and math, The Otis-Lennon School Ability Test index, and placement into special education or high achievement programs at the end of second grade. A weighted combination of subtests accurately predicted 77% of the children classified as special education students. The same battery also predicted 73% of the children who were classified as high-achieving students. 相似文献

The basic question addressed in this study was whether the discrepancies found between the Mental Processing Composite (ability component) and the Achievement subtests of the Kaufman Assessment Battery for Children (K-ABC) corresponded with the discrepancies found between the WISC-R Full Scale IQ and the PIAT subtests, or whether use of the K-ABC over the WISC-R and PIAT results in the identification of different students. The differences were evaluated using four standard score procedures for calculating a severe discrepancy. It was found that the K-ABC and WISC-R/PIAT approaches to the determination of a score difference resulted in the identification of different populations of students. The high average PIAT standard scores together with the lower subtest reliabilities appeared to be the primary source of disparity between the K-ABC and WISC-R/PIAT comparisons. 相似文献

This study investigated the validity of the WISC-R IQs as predictors of achievement as measured by the PIAT. Both tests were administered to 188 children referred to the author because of learning problems. Regression analyses were run with each of the PIAT subtests and the total score as criteria and the WISC-R IQs as predictors. Each of the IQs was a significant predictor of each of the PIAT subtests, but the Verbal IQ predicted best. Regression equations were provided and several indications of the importance of the results were presented. 相似文献

The usefulness of a particular standardized achievement test with a specific population may be determined largely on the basis of experience. Sixty-six behaviourally disturbed students were administered portions of a test battery including the Reading Recognition subtest of the Peabody Individual Achievement Test (PIAT), PIAT Reading Comprehension, the Reading subtest of the Wide Range Achievement Test (WRAT), and Stanford Diagnostic Reading Test (SDRT); PIAT Mathematics, WRAT Arithmetic, Stanford Diagnostic Mathematics Test (SDMT), and KeyMath Diagnostic Arithmetic Test. Toward the end of the academic year, teachers estimated students' grade levels in reading and mathematics. Results indicated that, in mathematics, the SDMT and the PIAT predicted teachers' ratings equally well and better than the other tests; in reading, all tests predicted teachers' ratings equally well except for the PIAT Reading Comprehension, which performed less well than others. Explanations for these results are offered, together with suggestions for identifying achievement tests suitable to specific populations. 相似文献

An operational index of discrepancy to assist in identifying learning disabilities (LD) in the cognitive domain was derived using the Full Scale IQ, Wechsler Intelligence Scale for Children (Wechsler, 1949, and relevant subtest scores on the Peabody Individual Achievement Test (PIAT) (Dunn and Markwardt, 1970. The index was applied to all legally identified LD children (N = 60) of a Michigan county who were in the LD program (1% of the total elementary school population of 6000 children). Of the 50 males and 10 females (mean age: 9 years 2 months; mean IQ: 91), the index identified 74% and 30% respectively as may be LD in the cognitive domain. This comprised 67% of the 60 children, or 2/3 of 1 % of the total elementary school population. Of the 67% may be LD children, 93% had discrepancy low PIAT subtest scores in Reading Recognition, 88% in Reading Comprehension, 83% in Spelling, and 52% in Arithmetic. Considerable caution should be exercised when classifying children, especially females, as LD. 相似文献

The utility of kindergarten screening measures in predicting first grade achievement was examined for 246 children classified as Anglo-American-English as home language (AA-E), Mexican-American-English as home language (MA-E), and Mexican-American-Spanish as home language (MA-S). All children were administered the Boehm Test of Basic Concepts, Draw-A-Design and Draw-A-Child subtests of the McCarthy Scales of Children's Abilities, and a Criterion Referenced Test at the beginning of kindergarten and at the end of kindergarten. The SRA Achievement Series was then administered during first grade. Stepwise multiple regression analyses were conducted for each group of children employing each set of kindergarten measures as predictors. All resulting equations were significant (p < .001) and revealed differential predictive power of the kindergarten measures as a function of ethnicity and home language, content of the criterion measures, and time of assessment. The Criterion Referenced Test was found to be a significant predictor of first-grade reading scores and the Draw-A-Design subtest emerged as a significant predictor of first-grade math achievement for the MA-S children, whereas the Boehm consistently emerged as a significant predictor and accounted for substantially more variance in first-grade reading and math scores for the AA-E and MA-E children. For all three groups, beginning kindergarten measures accounted for more variance in first-grade achievement than end of kindergarten measures. The importance of utilizing language measures, as well as predictive validity techniques, was discussed in relation to future cross-cultural research. 相似文献

The predictive validity of the WISC-R IQs and factor scores was examined with a sample of 64 Mexican-American children. All the correlations among the WISC-R factor scores and academic achievement as measured by the Wide Range Achievement Test (WRAT) were found to be low, ranging from .09 to .31. Significant relationships were observed only between WRAT Reading and Perceptual Organization (PO) factor, WRAT Arithmetic and PO factor, and Freedom from Distractibility (FD) factor and WRAT Arithmetic scores. In contrast to this, however, significant relationships were observed between IQ scores and achievement measures, suggesting predictive utility of the WISC-R IQs in predicting achievement for Mexican-American children. 相似文献

The Visual Aural Digit Span (VADS) and the Bender Visual Motor Gestalt Test (Bender) were studied with regard to their ability to discriminate low from average achievers in reading and arithmetic skills, as identified by the Iowa Test of Basic Skills. A sample of 78 normal children aged 6 through 9 were administered a battery of tests, including the verbal section of the WISC-R. Analysis of covariance with IQ controlled showed that the Bender and the VADS were able to discriminate between achievement groups for vocabulary and math concepts. The Bender discriminated between math problem-solving groups, but neither test could discriminate between reading comprehension groups. Age was a significant variable for the Bender and all VADS subtests except Aural-Written. Correlational analysis indicated that although the VADS was related to Verbal IQ, it is related only minimally to the Bender when age is controlled. 相似文献

Extended families of 12 young adults (9 LD, 3 non-LD) were given a battery of tests and questionnaires, and 131 persons, ranging
in age from 6 to 85, were classified as LD or non-LD on the basis of subtest scores 1 SD below the mean or less on subtests
of the PIAT and WRAT achievement tests. Pedigree analysis indicated that LD was strongly familial, with the most probable
mode involving a major gene effect, but the type of disability (reading/ math) was not directly inherited. Autoimmune disorders
were significantly correlated (P<.005) with LD, especially in families in which LD remained a major handicap into adulthood,
a trait that also varied between families. In two of the LD families, adults showed little evidence of the reading/spelling
deficits they had shown when tested as children, while adults in other families failed to make gains in reading and spelling. 相似文献

The Peabody Individual Achievement Test–Revised (PIAT‐R) and Wechsler Individual Achievement Test (WIAT) contain measures of written expression. However, these subtests are not theory‐based and were assessed with inappropriate psychometric analyses. This study attempted to enhance the study of written expression by reexamining the reliability and validity of the PIAT‐R and WIAT Written Expression scoring systems, applying theory and more appropriate statistical analyses. First, items were identified that were the most and least reliable, determined by interrater agreement. Next, the most and least valid items were identified, based on item–total correlations. Subjects included 50 adolescents, men, and women aged 13 to 46 years; raters were three graduate students with experience and training similar to that of the typical test user. Results indicate that seven items were too easy, as virtually all subjects received the maximum score on these items—these items were eliminated. The remaining 24 items were classified as both reliable and valid (9 items), reliable but not valid (4 items), valid with limited reliability (5 items), and neither reliable nor valid (6 items). The WIAT written expression scoring system was found to have more items that were both reliable and valid compared to the PIAT‐R scoring system. Items measuring global, rather than specific, content were also found to be more reliable and valid. © 1999 John Wiley & Sons, Inc. 相似文献

The purpose of this study was to examine the validity evidence of first-grade spelling scores from a standardized test of nonsense word spellings and their potential value within universal literacy screening. Spelling scores from the Test of Phonological Awareness: Second Edition PLUS for 47 first-grade children were scored using a standardized procedure and an alternative invented spelling procedure. Correlations were examined among spelling and diagnostic word reading and decoding scores, along with scores from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS). Spelling scores were significantly correlated with word reading and decoding scores, as well as DIBELS scores, except Phoneme Segmentation Fluency. Hierarchical multiple regression analyses revealed that spelling scores reliably accounted for significant variance in decoding but not word reading scores, beyond DIBELS scores. Implications are discussed related to the potential value of including early spelling scores within universal literacy screening. 相似文献
