This study examined the underlying constructs measured by the Differential Ability Scales (DAS; C.D. Elliott, 1990a) as they relate to the Cattell‐Horn‐Carroll (CHC) Theory (K.S. McGrew, 1997) of cognitive abilities. The DAS and Woodcock‐Johnson Tests of Cognitive Abilities (WJ‐III COG; R.W. Woodcock, K.S. McGrew, & N. Mather, 2001) were administered to 131 children in grades 3 through 5 who took part in a concurrent validity study included in the Woodcock‐Johnson Tests of Cognitive Abilities, Third Edition, technical manual (K.S. McGrew & R.W. Woodcock, 2001). Confirmatory factor analyses using maximum likelihood estimation were conducted with the AMOS 5.0 (J.L. Arbuckle, 2001) statistical program to evaluate three models of increasing complexity, to compare how well each fit the data set, and to identify the one that best described the underlying constructs measured by the DAS. Results suggested that the synthesized Three‐Stratum CHC Model provided the most parsimonious representation among the three models tested. © 2007 Wiley Periodicals, Inc.

This study assesses the predictive validity of the Phelps Kindergarten Readiness Scale (PKRS) for later academic achievement and explores the utility of a domain‐specific measure of kindergarten readiness. Kindergarten readiness scores were significantly correlated with both math and language arts achievement as measured by New York State fourth‐grade assessments for 148 students in a suburban, northeastern public school. In addition, each of the PKRS domains (Verbal, Perceptual, and Auditory) was correlated with later academic achievement. Two simultaneously calculated regression analyses showed that language arts skills were best predicted by the Verbal and Auditory domains of the PKRS and that math achievement was more complexly determined by all three readiness domains. Structural equation modeling using AMOS‐4 showed that the latent construct readiness, as measured by the PKRS domain scores, was positively and significantly related to the latent construct academic achievement. Finally, this relationship held when age, gender, and behavioral indices at the time of kindergarten screening were used as moderator variables. © 2004 Wiley Periodicals, Inc.

This study examined the relative contributions of measures of Cattell‐Horn‐Carroll (CHC) cognitive abilities in explaining writing achievement. Drawing from samples that covered the age range of 7 to 18 years, simultaneous multiple regression was used to regress scores from the Woodcock‐Johnson III (WJ III; Woodcock, McGrew, & Mather, 2001) that represent CHC broad and narrow abilities onto the WJ III Basic Writing Skills and Written Expression cluster scores. At most age levels, Comprehension‐Knowledge demonstrated moderate to strong effects on both writing clusters, Processing Speed demonstrated moderate effects on Basic Writing Skills and moderate to strong effects on Written Expression, and Short‐Term Memory demonstrated moderate effects. At the youngest age levels, Long‐Term Retrieval demonstrated moderate to strong effects on Basic Writing Skills and moderate effects on Written Expression. Auditory Processing, and Phonemic Awareness demonstrated moderate effects on only Written Expression at the youngest age levels and at some of the oldest age levels. Fluid Reasoning demonstrated moderate effects on both writing clusters only during some of the oldest age levels. Visual‐Spatial Thinking primarily demonstrated negligible effects. The results provide insights into the cognitive abilities most important for understanding the writing skills of children during the school‐age years. © 2008 Wiley Periodicals, Inc.  相似文献

Based on previous findings (McGrew, Flanagan, Keith, & Vanderwood, 1997) that auditory processing (Ga) predicts reading decoding, and crystallized intelligence (Gc) predicts reading comprehension beyond the prediction of reading by g(broad general intelligence), this study examined the cross‐ethnic predictive validity of Ga and Gc for reading achievement among low‐SES English‐speaking White and Hispanic students. Subtests of the Woodcock‐Johnson Psycho‐Educational Battery‐Revised (WJ‐R) cognitive subtests were used to measure Ga and Gc, and the WJ‐R achievement subtests were used to measure basic reading skills and reading comprehension. Results indicated that there are no differences between ethnic groups in the prediction of reading ability, and that phonetic coding and crystallized intelligence together are strong predictors of reading achievement. © 2000 John Wiley & Sons, Inc.  相似文献

This study examined the concurrent validity of the Slosson Full‐Range Intelligence Test (S‐FRIT) by comparing S‐FRIT scores to the scores of the Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Woodcock‐Johnson Tests of Achievement–Revised (WJ‐R). Data from 123 elementary students' screening and psychological testing results were examined. Results revealed that the S‐FRIT scores were more related to overall intelligence, verbal, and math abilities than nonverbal intelligence, reading, or written language abilities. Further, it was found that 89% of the participants' S‐FRIT Full‐Range IQ scores fell within one standard deviation of their WISC‐III FSIQ scores, with an average discrepancy of 7.6 points. Discrepancies between S‐FRIT and WISC‐III scores were also examined by educational diagnostic categories and ability levels. Limitations and suggestions for future research are provided. © 2002 John Wiley & Sons, Inc.  相似文献

This study examines cognitive ability profiles of children with specific age-based normative weaknesses in reading comprehension and compares those profiles to the profiles of (a) children with at least average achievement in reading comprehension, reading decoding skills, and mathematics and (b) children with low achievement across the 3 achievement areas. When compared across 9 cognitive ability composite scores derived from Cattell–Horn–Carroll theory and measured by the Woodcock–Johnson III [Woodcock, McGrew, & Mather (2001). Woodcock–Johnson. Itasca, IL: Riverside], groups differed in overall level of performance. When individual abilities were considered, the poor comprehenders scored significantly lower than the average achievement group on all nine composite scores and significantly lower than the normative population on all composite scores except Processing Speed and Long-Term Retrieval. In contrast, the poor comprehenders also scored significantly higher than the low achievement group on all composite scores except for Visual–Spatial Thinking and Phonemic Awareness. Although the poor comprehenders as a group scored lowest on composite scores measuring language- and knowledge-based abilities, review of the profiles of individual poor comprehenders revealed no consistent pattern of performance across cognitive ability composite scores.  相似文献

The validity and reliability of curriculum‐based measures in reading as indicators of performance and progress for secondary‐school students were examined. Thirty‐five grade 8 students completed reading aloud and maze‐selection measures weekly for 10 weeks. Criterion measures were the state standards test in reading and the Woodcock–Johnson III Test of Achievement. Different time frames for each measure were compared. Most alternate‐form reliability coefficients were above .80. Criterion‐related validity coefficients ranged from .77 to .89. No differences related to time were found. Only maze selection reflected significant growth, with an average increase of 1.29 correct choices per week. Maze growth was related to the reading performance level and to change on the Woodcock–Johnson III from pre‐ to posttest.  相似文献

This study examined the accuracy of three shortened measures of intelligence: the Woodcock–Johnson Tests of Cognitive Ability, Third Edition Brief Intellectual Ability (WJ III COG BIA) score; the Stanford–Binet Intelligence Scale, Fifth Edition Abbreviated IQ (SB5 ABIQ); and the Kaufman Brief Intelligence Test IQ Composite (K‐BIT) in predicting giftedness as assessed by the SB5 Full Scale IQ score (SB5 FSIQ). Participants were 202 third grade students who were individually administered the SB5, WJ III, and K‐BIT. Four scores (SB5 ABIQ, K‐BIT, WJ III COG BIA, and SB5 FSIQ) were extracted. Correlational analyses revealed positive, significant relationships among the four scores. Discriminant function analyses, conducted to examine the accuracy of the three shortened measures of intelligence in predicting giftedness, revealed that overall, the WJ III score was the most accurate, and the K‐BIT score was the least accurate in identifying giftedness. © 2008 Wiley Periodicals, Inc.  相似文献

The factor structure of the Woodcock Reading Mastery Tests–Revised (WRMT‐R) was analyzed using data from a sample of 140 special education students with learning disabilities, mild mental retardation, and serious emotional disturbance. Woodcock asserted that the WRMT‐R measured two important aspects of reading ability: Basic Skills and Reading Comprehension. According to Woodcock, the Word Identification and Word Attack Tests measure two elements of Basic Skills, and the Word Comprehension and Passage Comprehension Tests measure two elements of Reading Comprehension. Together, Basic Skills and Reading Comprehension produce the Total Reading Full‐Scale score. Principal axis factor analysis with a promax rotation and confirmatory factor analysis were used to evaluate evidence that the four tests of the WRMT‐R combine to form the two factors: Basic Skills and Reading Comprehension. The results of the analyses indicated a robust single factor (Total Reading Full‐Scale), and provided little support for Woodcock's hypothesized two‐factor structure. © 2001 John Wiley & Sons, Inc.  相似文献

Research Findings: A difficulty for developmental researchers is disambiguating children's general maturation from the influence of schooling. In this study, we use a natural experiment to examine the influence of prekindergarten and kindergarten schooling experiences on the development of literacy and mathematics. Children (n = 60) whose birthdates fell within 2 months of the state-determined cutoff date for prekindergarten and kindergarten entry were administered 4 subtests of the Woodcock–Johnson III Tests of Achievement in the fall and spring of the school year. Using hierarchical linear modeling coupled with propensity score matching, we found that children who were starting kindergarten and who had prior experience in prekindergarten had higher scores on measures of phonological awareness, early reading, and mathematics skills than did children who had not attended prekindergarten previously, even though they were essentially the same age. Fall vocabulary scores did not differ in relation to whether children had prekindergarten experience. In addition, although children who attended kindergarten as well as those who attended prekindergarten exhibited growth on all measures during the school year, children who attended kindergarten demonstrated greater gains in early reading and vocabulary during the school year. Practice or Policy: These findings highlight the potential of early schooling processes to facilitate children's intellectual growth.  相似文献

This study examined the reliability and validity of scores on a fluency‐based measure of reading comprehension. The Dynamic Indicators of Basic Early Literacy Skills (DIBELS; 6th ed. revised) Retell Fluency (RTF), Oral Reading Fluency (DORF), and Woodcock Johnson III NU Tests of Achievement (WJ‐III NU ACH) Reading Comprehension measures were administered to fourth‐grade students. Results indicated a large difference between real time and recorded retell fluency scores for each passage. In addition, students' retell fluency scores had a low correlation with their reading comprehension scores. In light of these findings, practitioners may want to exercise caution in using fluency‐based story‐retell scores as a measure of reading comprehension. © 2011 Wiley Periodicals, Inc.  相似文献

The present investigation examined the validity of the Comprehensive Test of Nonverbal Intelligence (CTONI) with the Woodcock‐Johnson III Tests of Cognitive Abilities (WJ‐III COG) by administering these instruments in counterbalanced order to 60 college students. Results indicated that the mean CTONI NIQ score was not significantly different from the mean WJ‐III COG General Intellectual Ability (GIA) score. However, mean score differences were found between the CTONI NIQ and the WJ‐III COG Verbal Ability, Thinking Ability, Comprehension‐Knowledge, and Fluid Reasoning cluster scores. Although the correlations between the CTONI and the WJ‐III COG cluster scores were generally of small magnitude, the CTONI Geometric Nonverbal IQ composite score demonstrated construct specificity, whereas the CTONI Pictorial Nonverbal IQ scale did not. The implications of the findings are discussed and practitioners are asked to use caution when using this instrument to assess the fluid reasoning abilities of college students. © 2007 Wiley Periodicals, Inc.  相似文献

Reading comprehension rate (RCR) is a direct measure of reading skills that may be useful in formatively evaluating students reading beyond the fourth‐grade level. To investigate the concurrent validity of RCR, we correlated RCR, reading comprehension level (RCL), and words correct per minute (WC/M) with the Broad Reading Cluster Scores of the Woodcock‐Johnson III Tests of Achievement (WJ‐III ACH) across 88 students in 4th, 5th, and 10th grades. Results showed that aloud‐RCR was significantly correlated with the WJ‐III ACH scores for 4th‐grade (r = .90; n = 22), 5th‐grade (r = .87; n = 29), and 10th‐grade (r = .65; n = 37) students. Regression analysis specified a one‐predictor model for 4th‐grade students (aloud‐RCR), a two‐predictor model for 5th‐grade students (WC/M and aloud‐RCR), and a one‐predictor model for 10th‐grade students (WC/M). Discussion focuses on directions for future research and applied issues related to RCR probe passage development. © 2007 Wiley Periodicals, Inc. Psychol Schs 44: 373–388, 2007.  相似文献

Relations between marital conflict, children's respiratory sinus arrhythmia (RSA), and fluid cognitive performance were examined over 3 years to assess allostatic processes. Participants were 251 children reporting on marital conflict, baseline RSA, and RSA reactivity (RSA‐R) to a lab challenge were recorded, and fluid cognitive performance was measured using the Woodcock–Johnson III. A cross‐lagged model showed that higher levels of marital conflict at age 8 predicted weaker RSA‐R at age 9 for children with lower baseline RSA. A growth model showed that lower baseline RSA in conjunction with weaker RSA‐R predicted the slowest development of fluid cognitive performance. Findings suggest that stress may affect development of physiological systems regulating attention, which are tied to the development of fluid cognitive performance.  相似文献

The psychometric properties of the Classroom Performance Profile (CPP), a teacher rating scale, were investigated using primary grade children from economically at‐risk families. Students were rated as they progressed from kindergarten through third grade. The CPP demonstrated high internal consistency yielding Cronbach alpha coefficients for the total score of at least .96. CPP ratings were correlated with scores from the Woodcock‐Johnson Psycho‐Educational Battery–Revised: Tests of Achievement and the Social Skills Rating System–Teacher Form, Elementary Level. Results suggest that the CPP ratings were positively correlated with measures of academic achievement, academic competence, and social skills, and negatively correlated with problem behaviors. © 2002 Wiley Periodicals, Inc.  相似文献

This study examined the concurrent validity of the General Ability Measure for Adults (GAMA1; Naglieri & Bardos, 1997) and the Wechsler Adult Intelligence Scale‐Third Edition (WAIS‐III; Wechsler, 1997). Sixty college students were administered both instruments in counterbalanced order. A comparison of the mean scores on the GAMA and WAIS‐III indicated that the sample obtained similar GAMA and WAIS‐III PIQ scores. In contrast, the sample's mean GAMA IQ score was significantly lower than the sample's mean FSIQ and VIQ scores. Although the GAMA IQ score was positively correlated with all WAIS‐III IQ and Index scores, this new instrument was more clearly associated with visual‐spatial reasoning, as defined by the WAIS‐III PIQ. The GAMA's accuracy in predicting performance on the WAIS‐III FSIQ and PIQ also was examined, with the GAMA underestimating WAIS‐III FSIQ and PIQ scores for participants falling within the Superior and Very Superior range of intellectual functioning. © 2001 John Wiley & Sons, Inc.  相似文献

Components of early number sense, as identified in two Delphi studies and in the number sense literature related to mathematics difficulties, were assessed for 176 children in preschools and childcare centres across one local government area in Sydney, Australia, using tasks or modifications of tasks reported in the number sense literature. In addition, the children’s receptive vocabulary was measured using The Peabody Picture Vocabulary Test (third edition) and math reasoning was measured using Woodcock‐Johnson III Tests of Achievement. Although the children demonstrated a broad range of skills, there were no significant differences between children attending childcare and preschools for any of the measures. However, boys performed significantly better than girls in quantitative concepts and girls performed better than boys in subitising. In discussing the data, a comparison is made of the skills demonstrated by children and skills that were highlighted in the two Delphi studies and in the early number sense literature as being essential components of number sense prior to school entry. Implications for kindergarten mathematics curricula and approaches to the teaching of early number skills are discussed.  相似文献

This study is an examination of the relationship of perceived social support and adolescents' adjustment behaviors over time. The sample (n = 82) included students from two at‐risk urban middle schools. Utilizing two measures, the Child and Adolescent Social Support Scale (CASSS; C. K. Malecki, M. K. Demaray, & S. N. Elliott, 2000) and the Behavior Assessment System for Children, Self Report of Personality (BASC; C. R. Reynolds & R. W. Kamphaus, 1998), data were collected at three time points. Results point to a relationship between social support and student adjustment behaviors over time. Specifically, support from parents was related to clinical maladjustment and emotional symptoms one year later. In fact, parent support was still related to clinical maladjustment one year later even after students' earlier levels of clinical maladjustment were taken into account. Parent support was also related to personal adjustment in the short term (6 months). Classmate support was related to students' emotional symptoms one year later. Finally, school support was related to school maladjustment one year later even after students' earlier school maladjustment was taken into account. Implications for school psychologists are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 691–706, 2005.  相似文献

Curriculum‐based measures have been validated for use in evaluating reading, mathematics, and writing skills (Marston, 1989). Despite its common use by school psychologists (Wilson & Reschly, 1996), the relationship between the Woodcock Johnson‐Revised and curriculum‐based measures of writing has not been evaluated. This study investigated the relationship between the Woodcock Johnson‐Revised Writing Samples subtest and alternate curriculum‐based measures of written expression. In addition, the sensitivity of the measures to the effects of a short group writing intervention was assessed. Forty‐five third and fourth graders participated in an intervention that consisted of brainstorming ideas, presenting those ideas on a dry‐erase board, and writing a complete sentence on paper with writing quality feedback before completing a CBM (curriculum‐based measurement) writing passage. Numbers of words written as well as five alternate measures of writing samples were used to assess the effects of the intervention. The intervention had a positive effect on total words written. Total punctuation marks, simple sentences, and words in complete sentences emerged as the best predictors of the Woodcock Johnson‐Revised Writing Samples subtest scores in regression analyses. The implications of the analyses, limitations of the study, and directions for future research are discussed. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 291–300, 2004.  相似文献
