Exploratory and confirmatory factor analyses of the Woodcock reading mastery tests–revised with special education students

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.     

The Relationship Among Oral Language,Decoding Skills,and Reading Comprehension in Children with Autism

The purpose of this study was to examine the relationship among oral language, decoding, and reading comprehension for children with autism. Participants included 13 English-speaking children with a diagnosis of high-functioning autism (IQ > 70) who were included in a typical classroom, and who had parents who spoke English. Parts of the Clinical Evaluation of Language Fundamentals, OWLS: Listening Comprehension, and the Peabody Picture Vocabulary Test were administered to measure oral language abilities, and parts of the Woodcock Reading Mastery Test and Test of Word Reading Efficiency were given to assess decoding and reading comprehension. Results indicated there was no significant relationship between phonology and decoding, but there was a significant relationship between semantics and decoding. There were also significant relationships between semantics and comprehension and syntax and comprehension.     

Using teacher judgment and IQ to estimate reading and mathematics achievement in a remedial-reading program

This study investigated the relative merits of using teacher judgment and the Slosson Full-Range Intelligence Test to estimate the math and reading achievement of students in a summer remedial-reading program. The subjects included children in grades kindergarten through six who were enrolled in the Auburn University Summer Clinic. Components analyses showed that the Slosson Full-Range Intelligence Test recovered substantially more variance from the distributions of the KeyMath-Revised and the Woodcock Reading Mastery Tests-Revised than did teacher judgments. Analysis of variance showed that significant differences between the means of the three tests resulted from the inclusion of students with learning disabilities. Implications of the results are discussed.     

Concurrent validity of the Slosson full‐range intelligence test: Comparison with the Wechsler intelligence scale for children–third edition and the Woodcock Johnson tests of achievement–revised

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.     

The Contribution of Naming Speed to the Simple View of Reading

The purpose of this study was to investigate whether naming speed makes a contribution to the prediction of reading comprehension, after taking into account the product of word decoding and listening comprehension (i.e., the Simple View of Reading; [Gough, P.B. & Tunmer, W.E. (1986). Remedial and Special Education 7, 6–10]), and phonological awareness. In grade 3, word decoding was measured with the Woodcock [(1998). Woodcock Reading Mastery Tests – Revised. Circle Pines, MN: American Guidance Services]. Word Identification and Word Attack subtests, listening comprehension with the Woodcock (1991) [Woodcock Language Proficiency Battery – Revised. Chicago: Riverside Publishing Company] test of Listening Comprehension, naming speed with a picture naming task, and 4 measures assessed phonological awareness. Reading comprehension was assessed in grades 3, 4, and 5 with the Woodcock (1998) Passage Comprehension subtest and in grade 5 with the Gates–MacGinitie reading test. The Simple View was evaluated twice: first, with a pseudoword measure for decoding (Grapheme–Phoneme-conversion product) and, second, with a word identification measure for decoding (word recognition product). Hierarchical regression and commonality analyses indicated that the decoding and listening comprehension products accounted for considerable variance in reading comprehension. Naming speed had a small but significant effect after accounting for the Grapheme–Phoneme-conversion product (2–3%), but little effect after accounting for the word-recognition product (0–2%). Subgroup analyses indicated that naming speed had its primary effect for less able readers. Commonality analyses supported the interpretation that naming speed contributes after the Grapheme–Phoneme-conversion product but not after the word recognition product because naming speed has already had its effect upon word recognition. These results indicate that it is important how the Simple View decoding term is defined, and that the Simple View may be incomplete, especially for less able readers.     

Reading Comprehension Tests Vary in the Skills They Assess: Differential Dependence on Decoding and Oral Comprehension

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.     

Improvements in interval time tracking and effects on reading achievement

This study examined the effect of improvements in timing/rhythmicity on students' reading achievement. 86 participants completed pre‐ and post‐test measures of reading achievement (i.e., Woodcock‐Johnson III, Comprehensive Test of Phonological Processing, Test of Word Reading Efficiency, and Test of Silent Word Reading Fluency). Students in the experimental group completed a 4‐week intervention designed to improve their timing/rhythmicity by reducing the latency in their response to a synchronized metronome beat, referred to as a synchronized metronome tapping (SMT) intervention. The results from this non‐academic intervention indicate the experimental group's post‐test scores on select measures of reading were significantly higher than the non‐treatment control group's scores at the end of 4 weeks. This paper provides a brief overview of domain‐general cognitive abilities believed effected by SMT interventions and provides a preliminary hypothesis to explain how this non‐academic intervention can demonstrate a statistically significant effect on students' reading achievement scores. © 2007 Wiley Periodicals, Inc.

The Slosson as a predictor of Wide Range Achievement Test performance

This study investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test, using the Slosson Intelligence Test For Children and Adults as the predictor. Ninety-five children referred for psychological evaluations in a five-county area in southeastern Nebraska were given both instruments, and a regression analysis was conducted where the Slosson IQ scores were separately regressed on Reading, Spelling and Arithmetic standard scores from the Wide Range Achievement Test. The results indicated that the Slosson IQ significantly predicts Wide Range standard scores. Derived regression equations are reported.     

The cognitive levels test: Its relationship with reading and mathematics achievement

Any instrument designed to measure broad cognitive ability is expected to correlate substantially with valid measures of academic achievement. This report describes an investigation designed to evaluate the relationship between the Cognitive Levels Test, a newly available instrument, and two tests of academic achievement that have been widely used for nearly two decades: the Woodcock Reading Mastery Tests and the KeyMath Diagnostic Arithmetic Test. The study included children in grades K-2 who were enrolled in a remedial summer school program. The results showed the Cognitive Levels Test (Cognitive Index) to be rather highly correlated with the KeyMath Diagnostic Arithmetic Test Total score (r=.72) and moderately correlated with the Woodcock Reading Mastery Tests Total Reading score (r=.55). A repeated measures analysis of variance comparing standard scores for the Cognitive Levels Test with those of the Woodcock Reading Mastery Tests indicated few mean differences between the two sets of scores. Implications concerning the validity of the Cognitive Levels Test were discussed.     

Predicting reading performance using the slingerland procedures

The purpose in this study was to examine predictive relationships between the Slingerland Pre- Reading Screening Procedures and performance on measures of word recognition and reading comprehension. Longitudinal data were collected on 104 children administered the Slingerland Procedures in kindergarten and the Stanford Achievement Test at first, third, and fifth grades. Outcome measures included achievement subtests, Word Study Skills, Reading Comprehension, Reading and Listening Total. Significant relationships were found between Slingerland measures and reading outcomes. However, prediction varied across grades and according to the measure of reading used. Listening contributed to reading comprehension but not to word recognition, and visual skills influenced early but not later reading performance. Gender and socioeconomic status influenced the strength of associations.     

Effectiveness of the DISTAR Reading I Program in Developing First Graders’ Language Skills

Abstract

The purpose of this study was to determine if the DISTAR Reading I program was more effective than a basal reading program in increasing school-based language ability. Additionally, I examined the hypothesis that DISTAR develops language more effectively for children who enter school with lower initial language ability than for children with higher language ability, as measured by the Metropolitan Readiness Test. Subjects were 80 Black 1st-grade learners randomly selected from two urban elementary schools. I assessed initial language with the language subtest of the Metropolitan Readiness Test. The adjusted mean score of the DISTAR classes on the posttest of the Slosson Intelligence Test was approximately 9 points higher than the adjusted mean of the basal reader group. Contrary to the second hypothesis, the DISTAR program was equally as effective for students with average or high initial language ability as for students with low initial language ability. The results are discussed as support for the proposition that the use of DISTAR direct-instruction procedures is a successful means of developing school-based language.     

Learning reading strategies by triggering reading motivation

In this article, the effectiveness of an intervention aimed at the development of reading motivation and reading strategies within problem-oriented learning environments is evaluated. The basic assumption underlying the intervention is that reading should occur in meaningful contexts and that reading and science should be regularly integrated. The intervention challenges pupils to investigate a self-formulated problem, read several books or texts on the topic and report the results of their study. The participants were six experimental third-grade classes and seven comparable control classes. The effects of the intervention were measured using a pretest-posttest control group design. Analyses of covariance were conducted to examine the effects as measured by a standardized Reading Comprehension Test, a Reading Comprehension Questionnaire, a Reading Strategy Test and a Reading Motivation Scale. The results showed the experimental group to outperform the control group with regard to knowledge of reading strategies (Reading Comprehension Questionnaire) and the use of such strategies (Reading Strategy Test). A significant difference in favour of the experimental group was also found for the Reading Motivation Scale. An effect on the standardized Reading Comprehension Test was not found.     

Convergent and concurrent validity of two measures of phonological processing

The purposes of this study were to determine the degree to which two measures of phonological awareness/ability (Test of Phonological Awareness; Comprehensive Test of Phonological Processing) correlate with each other and with a measure of reading (Letter‐Word Identification), and to determine which of the individual measures of phonological ability best predict early reading skill in kindergarten children. With one exception, all correlations among measures of phonological awareness/ability were significant. In addition, all correlations among the phonological awareness measures and the reading measure were significant. Multiple regression analyses revealed that the combination of all predictor variables accounted for approximately 51% of the variability in scores on the Woodcock Letter‐Word Identification subtest. The Phonological Awareness and the Rapid Naming composites of the CTOPP were the best predictors of performance on the measures of word identification. © 2002 Wiley Periodicals, Inc.     

Investigating Reading Achievement Using a Causal Model

The causes of high and low reading achievement were investigated using a causal model that involves 4 echelons of proximal and distal causes. In Study 1, 55 elementary students were individually administered a battery of tests in 2 sessions-around 2 hr each session on Saturdays. In Study 2, 83 students in Grades 4 and 5 were tested in their classrooms. There were 1 or more tests that were designed to measure almost all of the constructs in the causal model, plus 2 tests from the Woodcock Reading Mastery Tests (Woodcock, 1973) and the Reading Comprehension test from the Iowa Tests of Basic Skills (H. D. Hoover, Hieronymus, Frisbie, & Dunbar, 1993). The results generally were consistent with the causal model because (a) the fit of structural equations to the first 3 echelons of the model was. 89 or higher in 8 analyses, and (b) when the best measures of each construct were used, the normed-fit-index (Bentler & Bonett, 1980) was. 98 in Study 1 and. 95 in Study 2. There was considerable correlational support for the first 3 echelons of the causal model of reading achievement, that is (a) the 2 proximal causes of reading achievement are reading level and rate level, (b) the 2 proximal causes of reading level are verbal knowledge level and word identification knowledge level, and (c) the 2 proximal causes of rate level are word identification knowledge level and naming speed level. However, the 2 measures that were developed to measure verbal aptitude and pronunciation aptitude, at Echelon 4 of the model, were not highly consistent with the hypothesized causal connections. An implication of the model is that teaching and learning relevant to improving listening comprehension (meaning emphasis) and word identification (code emphasis) proximally affect verbal knowledge and pronunciation knowledge, and distally affect reading level, reading rate, and reading achievement.     

How word decoding, vocabulary and prior topic knowledge predict reading comprehension. A study of language-minority students in Norwegian fifth grade classrooms

This study examined the contribution of word decoding, first-language (L1) and second-language (L2) vocabulary and prior topic knowledge to L2 reading comprehension. For measuring reading comprehension we employed two different reading tasks: Woodcock Passage Comprehension and a researcher-developed content-area reading assignment (the Global Warming Test) consisting of multiple lengthy texts. The sample included 67 language-minority students (native Urdu or native Turkish speakers) from 21 different fifth grade classrooms in Norway. Multiple regression analyses revealed that word decoding and different facets of L2 vocabulary explained most of the variance in Woodcock Passage Comprehension, but a smaller proportion of variance in the Global Warming Test. For the Global Warming Test, prior topic knowledge was the most influential predictor. Furthermore, L2 vocabulary depth appeared to moderate the contribution of prior topic knowledge to the Global Warming Test in this sample of language minority students.     

Hearing Matters More Than Seeing: A Cross-Modality Study of Statistical Learning and Reading Ability

ABSTRACT

There is growing interest in the link between implicit statistical learning (SL) and reading ability. Although learning to read involves both auditory and visual modalities, it is not known whether reading skills might be more strongly associated with auditory SL or visual SL. Here we assessed SL across both modalities in 36 typically developing children and 36 healthy adults using the classic triplet-learning paradigm. Auditory SL was significantly associated with sentence reading fluency (Woodcock Johnson III Test of Achievement) in the combined sample of children and adults after controlling for age and nonverbal intelligence. In further analysis of the child data, auditory SL was significantly associated with nonword reading accuracy (Woodcock Reading Mastery Test), a relationship which appeared to be mediated by phonological processing abilities (Comprehensive Test of Phonological Processing). These findings suggest that auditory SL might contribute more strongly to certain aspects of reading development compared to visual SL.     

Employing teachers' ratings in selection of achievement tests in reading and mathematics with a behaviorally disturbed population

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.     

Curriculum bias and reading achievement test performance

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.     

Development and validation of a reading-related assessment battery in Malay for the purpose of dyslexia assessment

Malay is an alphabetic language with transparent orthography. A Malay reading-related assessment battery which was conceptualised based on the International Dyslexia Association definition of dyslexia was developed and validated for the purpose of dyslexia assessment. The battery consisted of ten tests: Letter Naming, Word Reading, Non-word Reading, Spelling, Passage Reading, Reading Comprehension, Listening Comprehension, Elision, Rapid Letter Naming and Digit Span. Content validity was established by expert judgment. Concurrent validity was obtained using the schools' language tests as criterion. Evidence of predictive and construct validity was obtained through regression analyses and factor analyses. Phonological awareness was the most significant predictor of word-level literacy skills in Malay, with rapid naming making independent secondary contributions. Decoding and listening comprehension made separate contributions to reading comprehension, with decoding as the more prominent predictor. Factor analysis revealed four factors: phonological decoding, phonological naming, comprehension and verbal short-term memory. In conclusion, despite differences in orthography, there are striking similarities in the theoretical constructs of reading-related tasks in Malay and in English.     

Comparison of reading disabled children's scores on the WISC-R,Peabody Picture Vocabulary Test,and Slosson Intelligence Test

Scores on the Slosson Intelligence Test and Peabody Picture Vocabulary Test, two frequently used screening devices, are examined to determine how well they predict scores on the Wechsler Intelligence Scale for Children—Revised. Two hundred seven children representing reading disabled children in the average classroom were administered each of the three measures of this study. The degree of relationship between the PPVT and the WISC-R was found to be.57, and the degree of relationship between the SIT and the WISC-R was found to be.73. The results of this study suggest that the PPVT and SIT measure different and/or limited aspects of a child's ability as measured by the WISC-R and are therefore only rough estimates of capacity to function in situations requiring what is generally termed intelligence.
