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

In order to clarify the concurrent validity of the Peabody Individual Achievement Test (PIAT) and the Metropolitan Achievement Test (MAT), product-moment correlations were computed for all subscores and total scores for 26 normal-range public school third-grade girls and boys. The reading comprehension subtests correlated.81, spelling.88, and PIAT Mathematics with MAT Total Math.64. Correlations were computed for the Otis-Lennon Mental Ability Test and the PIAT General Information subtest as.77, and the Otis-Lennon and the PIAT Total Test scores as.79. Concurrent validity of the PIAT with both tests is tentatively considered adequate except in the area of mathematics, in which the PIAT, relative to the MAT, appears to be reflecting ability to handle math concepts (.68) more accurately than math computation (.41) or math problem solving (.56). Correlations with IQ partialed out suggest the PIAT Total Test, and PIAT and MAT reading and spelling measures, are relatively uninfluenced by IQ variations, whereas with IQ held constant, the weak positive correlations between the PIAT and MAT math subtests became essentially random relationships. 相似文献

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

This study analyzed the factor structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Picture Vocabulary Test (PPVT), and the Peabody Individual Achievement Test (PIAT) in a psychiatric sample that ranged in age from 6 to 16 years (mean age = 11.1 years; SD = 3.0). The resultant factor structure of this sample was compared with patterns reported on normal and learning-disabled children. The subjects were 329 children under inpatient and outpatient care who had been referred for emotional disturbances. The results were similar to previous factor analytic studies of the WISC-R and PIAT, showing four factors: Verbal Comprehension, Verbal Achievement, Perceptual Organization, and Number Facility. The implications for the interpretation of these tests in a psychiatric sample and the appropriateness of a maximum likelihood technique in analysis of psychometric data are discussed. 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

Comprehension tests are often used interchangeably, suggesting an implicit assumption that they are all measuring the same thing. We examine the validity of this assumption by comparing some of the most popular reading comprehension measures used in research and clinical practice in the United States: the Gray Oral Reading Test (GORT), the two assessments (retellings and comprehension questions) from the Qualitative Reading Inventory (QRI), the Woodcock–Johnson Passage Comprehension subtest (WJPC), and the Reading Comprehension test from the Peabody Individual Achievement Test (PIAT). Modest intercorrelations among the tests suggested that they were measuring different skills. Regression analyses showed that decoding, not listening comprehension, accounts for most of the variance in both the PIAT and the WJPC; the reverse holds for the GORT and both QRI measures. Large developmental differences in what the tests measure were found for the PIAT and the WJPC, but not the other tests, both when development was measured by chronological age and by word reading ability. We discuss the serious implications for research and clinical practice of having different comprehension tests measure different skills and of having the same test assess different skills depending on developmental level. 相似文献

The Peabody Individual Achievement Test was administered to matched samples of 30 Mexican-American and 30 Anglo-American children. Split-half reliabilities for both groups were similar to stability reliabilities found in standardization. Indices of internal consistency and standard errors of measurement were generally equivalent for groups. It was concluded that the PIAT is as reliabel with Mexican-American children as with their Anglo counterparts. 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

The authors replicated a study (White, 1979) in which high correlations were obtained among the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Individual Achievement Test (PIAT), and the Goodenough-Harris Draw-A-Man (DAM), and conclusions were drawn that all these instruments might not be necessary in the same test battery. The present study involved a larger sample (360 children). Much lower correlations among the instruments were obtained, although the pattern of correlation was similar. It was concluded that results of the White study may have overestimated the relationships between the variables because of factors unique to the sample. Test specificity appeared using the larger, normally distributed sample, suggesting a legitimate use of all three tests in a single battery. 相似文献

The Peabody Individual Achievement Test has attained widespread use in the academic assessment of school-age children. Despite its popularity, little has been published regarding the appropriate interpretation of the five subtests making up the PIAT. The present paper provides standard errors of measurement of scaled scores for each subtest at five grade levels. Differences in scaled score units required at .05 and .01 significance levels for comparing each subtest to the mean subtest score are provided, and implications for interpretation are discussed. 相似文献

This study investigated the cognitive abilities as measured by the Inventory of Piaget's Developmental Tasks (IPDT) (Furth, 1970) of male and female fourth and fifth graders with learning disabilities. In addition, their cognitive abilities were compared to their reading and mathematics achievement, as measured by the Peabody Individual Achievement Test (PIAT) (Dunn & Markwardt, 1970). A two-way analysis of covariance revealed a significant mean difference in cognitive ability between students with learning disabilities and nondisabled students. No significant differences existed in performance between males and females. Multiple regression showed that a linear combination of reading and mathematics achievement yielded a significant positive correlation to cognitive ability. 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

Examiners seeking guidance on multiple‐choice and true/false tests are likely to encounter various faulty or questionable ideas. Twelve of these are discussed in detail, having to do mainly with the effects on test reliability of test length, guessing and scoring method (i.e. number‐right scoring or negative marking). Some misunderstandings could be based on evidence from tests that were badly written or administered, while others may have arisen through the misinterpretation of reliability coefficients. The usefulness of item response theory in the analysis of academic test items is briefly dismissed. 相似文献

In this investigation, the relationships between the Revised Peabody Picture Vocabulary Test, the Peabody Individual Achievement Test, and McCarthy Scales of Children's Abilities were explored. The sample included 26 children randomly selected from three classes in an elementary school. The Revised Peabody Picture Vocabulary Test correlated positively and significantly with the Peabody Individual Achievement Test's total score (.53) and most of its subtests. The Revised Peabody Picture Vocabulary Test also correlated significantly with the Verbal, Quantitative, Memory, and General Cognitive Indexes of the McCarthy Scales (Median r = .76). The mean Peabody Picture Vocabulary Test score was 104.6 and nearly identical to the McCarthy General Cognitive Index (104.4) but significantly smaller than the Peabody Individual Achievement total test score (114.5). 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

In this investigation, the relationships between the McCarthy Scales General Cognitive Index, the McCarthy Screening Test, Kaufman's McCarthy short form, and the Peabody Individual Achievement Test were examined. The sample included 39 children randomly selected from four classes in an elementary school. Results indicated that the Estimated General Cognitive Index by Kaufman's short form was virtually identical to the McCarthy Scales (full form) Index. The McCarthy Scales, McCarthy Screening Test, and Kaufman's short form all correlated significantly (p=.01) with the Peabody Individual Achievement Test, with the exception of the McCarthy Motor Scale. Moreover, there was no significant difference between the Peabody Total Test/Kaufman McCarthy short form correlation of.55 and the Peabody Total Test/McCarthy Screening Test correlation of.54 (t=0.09). Implications of these findings are discussed. 相似文献

Assessing Pupils’ Progress (APP) arose from a government drive to increase the amount of teacher-based assessment within school and to make this consistent across schools. We conducted semi-structured interviews with head teachers to gain insight into how their schools applied APP and we compared the APP levels for English and Maths, provided by teachers across 11 schools for 72 pupils, to a standardised assessment (Wechsler Individual Achievement Test-II; WIAT). There was a strong correlation between the APP and WIAT for literacy but not for numeracy. Head teacher interviews revealed that APP is used differently across schools and at times is used in a way inconsistent with government guidance, which raises the question of how teacher assessments are used and their purpose. Questions that should be considered are; how is moderation used in schools, what is the function(s) of teacher assessments and what is good practice in relation to these assessments? Clarity about the function of assessments is of vital importance as is ensuring that assessments are meaningful to teachers, pupils, families and schools, especially in light of the weight that can be placed on teacher assessments for all these groups. 相似文献

This prospective longitudinal study, using data from the National Longitudinal Survey of Youth (NLSY; N = 614), addresses the gap in the research literature regarding the effects of welfare reform on children. Key questions addressed include whether welfare dynamics and support services relevant to welfare reform, both measured across the first 5 years of life, are associated with mothers' earnings in the 6th year and three child cognitive outcomes in the 7th and 8th years: Peabody Individual Achievement Test (PIAT) math and reading scores, and the Peabody Picture Vocabulary Test (PPVT). Welfare dynamics are represented by total time on welfare, degree of cycling on and off welfare, and degree to which welfare and work are combined. Support services measured include three forms of child care (relative, babysitter, and center-based), as well as three forms of human capital supports (child support, job training, and education). Controlling for a range of background factors and for different patterns of welfare use across the first 5 years, small positive associations with mother's earnings were found for child support, education, and job training. Small positive associations also were found between child support and both math and reading scores. Finally positive associations of medium effect size were found between center care and both mothers' earnings and child PPVT scores. Although effect sizes are generally small, the results suggest the potential value of welfare reform approaches that emphasize long-term human capital development. Interactions between welfare dynamics and support services suggest subgroup differences. Specifically, positive effects of support services on earnings are strongest among mothers with higher levels of human capital (higher levels of work while on welfare, lower total time on welfare). Babysitter care appears to have negative effects on both reading and math scores of children whose mothers report low levels of work while on welfare. Implications for welfare reform policy are discussed. 相似文献
