A componential approach to understanding reading and its difficulties in preadolescent readers

The present study is predicated on the logic of interrelated functional information processing components as an approach to understanding reading and its difficulties in preadolescent readers. The structural equation modelling (and its variants) involved these three latent components: (a) orthographic/phonological component, (b) morphological component, and (c) sentence and paragraph comprehension component. These components were subserved by a total of ten measurable tasks, all administered on-line via the microcomputer under laboratory conditions with reaction time measures as indices of mental representation of word knowledge and sentence/paragraph comprehension. The latent dependent component of reading performance was subserved by standardized vocabulary and reading comprehension tests. The total sample consisted of 298 children in grades, 4, 5, and 6. Maximum likelihood analyses using LISREL show that the data in general do not disconfirm the proposed model for grade 4 readers. The three-component model, with some variables set free, provides a reasonable fit for the grade 5 data but less claim could be made about the goodness of fit for grade 6. The results show the mutually reinforcing and mutually facilitating effects of multilevels and multicomponents of reading. Word structure and word knowledge are particularly predictive of reading. The present Phase 1 work would be validated in a follow-up of another cohort of readers and would also lead to the systematic training of some of the components with poor readers. This study was supported by a grant (No. 410-86-0048) from the Social Sciences and Humanities Research Council of Canada.     

Augmenting the Simple View of Reading for Struggling Adult Readers: A Unique Role for Background Knowledge

This study explored the background knowledge (BK) and reading comprehension (RC) relationship for struggling adult readers. Using confirmatory factor analyses, a single-factor BK model exhibited better fit than a two-factor model separating academic knowledge and general information, which indicates that BK represents a unidimensional construct for this population. In addition, one measure of oral vocabulary loaded with a latent factor of BK, which was separable from a latent factor of two additional oral vocabulary subtests. Using structural equation modeling, we found that BK exhibited a direct effect on RC after controlling for participants’ grade level, decoding, listening comprehension, and oral vocabulary.     

Exploration of the Developmental Components Contributing to Elementary School Children's Reading Comprehension

The purpose of this study was to compare rauding theory (Carver, 1995) to our own evolving model of reading acquisition, which supports stage and phase theories of reading development. The relations among rauding variables--cognitive power, auditory-accuracy level, word-recognition level, comprehension-accuracy level, reading-rate level, and reading-comprehension-rate level-were examined using structural equation modeling. The Kaufman Assessment Battery for Children and the Kaufman Test of Educational Achievement subtests were used to operationalize the various constructs. Carver's (1993) model was assessed at each grade in two parts, with overlapping paths allowing cross-validation of some coefficients. For Grades 1 and 2, the fit indices were above. 95, indicating a good model fit. One additional path was supported-from word recognition to reading comprehension rate. The fit indices for Grades 3 and 4 were above. 95, supporting the modified Carver model. Analyses for Grades 5 and 6 produced fit indices above. 90, indicating drops in the level of association among the variables compared to earlier grades. The results of this study offer support to Carver's (1993) rauding theory and further advance the theories that children go through stages or phases of reading development. Although word recognition is a notable component of reading development throughout the elementary grades, its contribution to comprehension begins to lessen at Grades 5 and 6. There is, however, an increase with grade of the influence of cognitive power on reading comprehension, which is greater for crystallized (Peabody Picture Vocabulary Test-Revised) intelligence than for global (fluid and crystallized) or fluid intelligence.     

Is oral/text reading fluency a “bridge” to reading comprehension?

In the present study we investigated developmental relations among word reading fluency, listening comprehension, and text reading fluency to reading comprehension in a relatively transparent language, Korean. A total of 98 kindergartners and 170 first graders in Korea were assessed on a series of tasks involving listening comprehension, word reading fluency, text reading fluency, and reading comprehension. Results from multigroup structural equation models showed that text reading fluency was a dissociable construct from word reading fluency for both kindergartners and first graders. In addition, a developmental pattern emerged: listening comprehension was not uniquely related to text reading fluency for first graders, but not for kindergartners, over and above word reading fluency. In addition, text reading fluency was uniquely related to reading comprehension for kindergartners, but not for first graders, after accounting for word reading fluency and listening comprehension. For first graders, listening comprehension dominated the relations. There were no differences in the pattern of relations for skilled and less skilled readers in first grade. Results are discussed from a developmental perspective for reading comprehension component skills including text reading fluency.     

A dominance analysis approach to determining predictor importance in third, seventh, and tenth grade reading comprehension skills

The purpose of the present study was to investigate and rank order by importance the contributions of various cognitive predictors to reading comprehension in third, seventh, and tenth graders. An exploratory factor analysis revealed that for third grade, the best fit was a four-factor solution including fluency, verbal reasoning, nonverbal reasoning, and working memory factors. For seventh and tenth grade, three-factor solutions with fluency, reasoning, and working memory factors were the best fit. The three and four-factor models were used in separate dominance analyses for each grade to rank order the factors by predictive importance to reading comprehension. Results indicated that fluency and verbal reasoning were the most important predictors of third grade reading comprehension. For seventh grade, fluency and reasoning were the most important predictors. By tenth grade, reasoning was the most important predictor of reading comprehension. Working memory was the least predictive of reading comprehension across all grade levels. These results suggest that inferential reasoning skills become an important contributor to reading comprehension at increasing grade levels.     

Using structural equation modeling to fit models incorporating principal components

The aim of this article is to consider models incorporating principal components from the perspective of structural equation modeling. These models include the principal component analysis of patterned matrices, multiple analysis of variance based on principal components, and multigroup principal component analysis. We demonstrate that these models can be fit readily using the programs LISREL 8 and Mx. The models and certain extensions are discussed, and several illustrations are given.     

Developmental Relations Between Vocabulary Knowledge and Reading Comprehension: A Latent Change Score Modeling Study

The present study followed a sample of first‐grade (N = 316, M_age = 7.05 at first test) through fourth‐grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and reading comprehension to test for the presence of leading and lagging influences. Univariate models indicated growth in vocabulary knowledge, and reading comprehension was determined by two parts: constant yearly change and change proportional to the previous level of the variable. Bivariate models indicated previous levels of vocabulary knowledge acted as leading indicators of reading comprehension growth, but the reverse relation was not found. Implications for theories of developmental relations between vocabulary and reading comprehension are discussed.     

The simple view of reading redux: vocabulary knowledge and the independent components hypothesis

This study investigated the hypothesis that the contributions of oral language comprehension (C) and word recognition (D) to reading comprehension (R) in the simple view of reading (SVR) are not independent because a component of C (vocabulary knowledge) directly contributes to the variance in D. Three analysis procedures (hierarchical regression analysis, exploratory factor analysis, and structural equation modeling) were used to analyze data obtained from a sample (N = 122) of 7-year-old students who were administered tests of vocabulary knowledge, nonword reading, word recognition (two standardized tests), and parallel forms of listening and reading comprehension. Results from the regression analysis indicated that vocabulary made a contribution to R beyond that made by word recognition and listening comprehension; results from the exploratory factor analysis showed that two factors (Decoding and Linguistic Comprehension) were extracted, with vocabulary and listening comprehension loading highly on the Linguistic Comprehension factor; and results from structural equation modeling revealed that the latent construct, C, influenced R not only directly but also indirectly through the latent construct, D.     

Relations Among Oral Reading Fluency,Silent Reading Fluency,and Reading Comprehension: A Latent Variable Study of First-Grade Readers

In the present study, we examined oral and silent reading fluency and their relations with reading comprehension. In a series of structural equation models with latent variables using data from 316 first-grade students, (a) silent and oral reading fluency were found to be related yet distinct forms of reading fluency, (b) silent reading fluency predicted reading comprehension better for skilled readers than for average readers, (c) list reading fluency predicted reading comprehension better for average readers than for skilled readers, and (d) listening comprehension predicted reading comprehension better for skilled readers than for average readers.     

Is the Whole Greater Than the Sum of Its Parts? Modeling the Contributions of Language Comprehension Skills to Reading Comprehension in the Upper Elementary Grades

Language comprehension is crucial to reading. However, theoretical models and recent research raise questions about what constitutes this multifaceted domain. We present two related studies examining the dimensionality of language comprehension and relations to reading comprehension in the upper elementary grades. Studies 1 (Grade 6; N = 148) and 2 (Grade 3–5; N = 311) contrasted factor models of language comprehension using item level indicators of morphological awareness and vocabulary (Studies 1 and 2) and syntactic awareness (Study 2). In both studies, a bifactor model—including general language comprehension and specific factors for each language component—best fit the data, and general language comprehension was the strongest predictor of reading comprehension. In Study 2, the morphology-specific factor also uniquely predicted reading comprehension above and beyond general language comprehension. Results suggest the value of modeling the common proficiency underlying performance on tasks designed to tap theoretically distinct language comprehension skills.     

What We Know,What We Still Need to Know: Teaching Adolescents to Write

The purpose of this study was to uncover any differences in the early reading and spelling processes of children learning to read in a first language (L1) and children learning to read in a second language (L2). The reading and spelling development of native Dutch-speaking children and minority children in the first two grades of elementary school were compared. The children were given a number of tasks to test their vocabulary knowledge and the efficiency of their word decoding (including grapheme knowledge and word blending), word spelling (including cipher knowledge and phonemic segmentation), and reading comprehension processes. Analyses of variance were used to test for differences between the L1 and L2 learners. LISREL analyses were used to explore the components underlying the reading and spelling processes in the 2 groups of children. The results showed that the minority children kept up with the native Dutch-speaking children on word blending and word decoding tasks. On word spelling and reading comprehension, however, the minority children were found to be less efficient than their monolingual Dutch peers. The structural models for word decoding and word spelling were highly comparable for the 2 groups. For reading comprehension, vocabulary knowledge was found to have more of an impact on the L2 learners than on the L1 learners. This finding suggests that children learning to read in an L2 should be helped to build their lexical knowledge and that reading instruction should be matched to this knowledge.     

Prosodic reading,reading comprehension and morphological skills in Hebrew‐speaking fourth graders

Employing prosody skilfully, one of the cornerstones of fluent reading, is an indicator of text comprehension. Morphological knowledge has been shown to underlie lexical acquisition and to be related to reading development. The relationship between reading comprehension, prosodic reading and morphological knowledge was investigated in 51 Hebrew‐speaking fourth‐grade students aged 9–10. Participants were tested on comprehension of two stories and on appropriate prosodic reading of one of them. Their prosodic reading was compared with an agreed prosodic map compiled from experts' reading. Participants were also administered a battery of morphological tasks. All three domains, including almost all of their component parts, were strongly correlated. The multiple regression in steps showed that morphology and reading comprehension each contribute to prosodic reading, while morphology and prosody each contribute to reading comprehension. The connection between reading comprehension and prosodic reading is however moderated by good morphological skills.     

Training Orthographic and Sentence Structures Helps Poor Readers in Chinese

We trained 36 12-year-old Chinese students with reading disorders in the analysis, synthesis and integration of orthographic constituents of semantic and phonetic bujians (radicals); and also their writing (spelling and composing) skills. These target students were compared with 37 age-controls in a pre-test and post-test design on a number of reading literacy indicators predicated on the “Blueprint of the Reader”. The tasks were: essay writing; morphological compounding; correction of errors; segmentation; text comprehension; fluency; copying of words, and of texts; writing to dictation; and reading aloud words and text. A promax oblique structure analysis of the performance of the 73 students found the tasks clustered into four components. A two (group) × 11 (tasks) multivariate analysis of covariance with the pre-training tasks as covariates followed by analyses of variance showed that the experimental students outperformed their age-peers in essay writing, morphological compounding, correction of errors, text comprehension and reading text aloud. They were also highly satisfied with their training as shown in a questionnaire survey.     

Investigating profiles of lexical quality in preschool and their contribution to first grade reading

This longitudinal study investigated profiles of lexical quality domains in preschool children and the extent to which profile membership predicted reading comprehension in first grade. A latent profile analysis was conducted to classify 420 preschool children on lexical quality domains, including orthography, phonology, morphosyntax, and vocabulary. Regression analysis was used to determine whether profile membership was associated with first grade outcomes across reading comprehension and its components (i.e., listening comprehension and word recognition). Results revealed five profiles of lexical quality which were predictive of all three outcomes in first grade. Children in low lexical quality profiles performed more poorly on the outcome measures than children in the higher lexical quality profiles. Additionally, profile membership did differentially predict later reading outcomes. These results suggest that lexical quality profiles are associated with reading and therefore may offer a means of early identification of children who are susceptible to future reading difficulties.     

Not all reading disabilities are alike

In this article, reading disability is defined broadly to refer to below-average achievement in reading comprehension as assessed by a standardized test. With our research we tried to answer the question of whether all children with reading disability share a common etiology of deficient phonology, or constitute heterogeneous groups. The answer to this question was sought in four studies that examined reading disabilities from the perspective of componential skills of reading. In Part 1, the results of the first study are reported. A principal-components analysis of the performance of 139 children from Grades 3, 4, and 6 on reading-related tasks yielded two factors: decoding and comprehension. However, factor analyses conducted for each grade separately indicated that orthographic skill and processing speed could possibly constitute a third component. The orthography-speed factor emerged as a factor only in the 6th grade. Part 2 of this article reports the findings of three studies that analyzed the componential skills profiles of poor readers. It was found that the poor readers constituted heterogeneous groups and that four different types of poor readers could be identified with deficiency in any one of the following skills: (a) decoding only, (b) comprehension only, (c) a combination of decoding and comprehension, and (d) a combination of orthographic processing and reading speed. It was also found that the criteria used in selecting poor readers influenced the distribution of the ratio of the four types of poor readers within any given group.     

A latent variable approach to the simple view of reading

The present study utilized a latent variable modeling approach to examine the Simple View of Reading in a sample of students from 3rd, 7th, and 10th grades (N = 215, 188, and 180, respectively). Latent interaction modeling and other latent variable models were employed to investigate (a) the functional form of the relationship between decoding and linguistic comprehension in third grade, (b) the contribution of these predictors as children progress through school, and (c) the contribution of passage fluency, working memory, and performance IQ to a model of reading for all grades. Results did not support the Simple View of Reading for students in grades 3, 7 and 10. Additionally, it was found that passage fluency significantly predicted reading comprehension after controlling for decoding and linguistic comprehension for students in grades 7 and 10. Likewise performance IQ was found to be a significant predictor of reading comprehension for students in third grade.     

The Role of Orthographic and Semantic Learning in Word Reading and Reading Comprehension

We tested the theoretically driven hypotheses that children’s orthographic and semantic learning are associated with their word reading and reading comprehension skills, even when orthographic and semantic knowledge are taken into account. A sample of 139 English-speaking Grade 3 children completed a learning task in which they read stories about new inventions. Then they were tested on their learning of the spelling and meaning of the inventions (i.e., orthographic and semantic learning, respectively). Word reading and reading comprehension were assessed with standardised tasks, and orthographic and semantic knowledge were assessed with choice tasks targeting the spelling and meaning of existing words. The results of our structural equation modeling indicated that orthographic learning predicted word reading directly and reading comprehension indirectly via word reading. We also found that semantic learning predicted reading comprehension directly. These findings support integration of the self-teaching hypothesis and the lexical quality hypothesis.     

Relations among reading skills and sub-skills and text-level reading proficiency in developing readers

Despite the recent attention to text reading fluency, few studies have studied the construct of oral reading rate and accuracy in connected text in a model that simultaneously examines many of the important variables in a multi-leveled fashion with young readers. Using Structural Equation Modeling, this study examined the measurement and structural relations of the rate and accuracy of variables important in early reading: phonemic blending, letter sounds, phonograms, decoding, single-word reading, reading comprehension, and text reading as well as reading comprehension among second grade readers. The effects from phonemic blending fluency and letter sound fluency to decoding were completely mediated by phonogram fluency, decoding fluency, single-word reading fluency, and reading comprehension had direct effects on the text reading fluency of the second grade students. Understanding the relationship among the many component skills of readers early in their reading development is important because a deficiency in any of the component skills has the potential to affect the development of other skills and, ultimately, the development of the child as a proficient reader.     

Metacognitive strategies and reading comprehension in elementary-school students

The aim of this study was to explore comprehension monitoring and perceived use of reading strategies as factors of reading comprehension. Participants were elementary school students from the fifth to the eighth grade. Error correction and text sensitivity tasks from the Metacomprehension test (Pazzaglia, De Beni, &; Cristante, 1994). and the cloze-task were used as measures of comprehension monitoring during reading. A Strategic reading questionnaire (Koli?-Vehovec &; Baj?anski, 2001b) was applied as a measure of perceived use of strategies during reading. Girls had better results than boys on text comprehension, all measures of comprehension monitoring, as well as on the Strategic reading questionnaire. Significant developmental improvements in comprehension monitoring occurred after the fifth grade and between the sixth and the eighth grade. A similar change was evident in reading comprehension. All measures of comprehension monitoring were significantly related to text comprehension in all age groups. However, perceived use of reading strategies was significantly related to reading comprehension only in eighth-grade students.     

Cognitive component of componential model of reading applied to different orthographies

Whether the simple view of reading (SVR) as incorporated in the componential model of reading (CMR) is applicable to other orthographies than English was explored in this study. Spanish, with transparent orthography and Chinese, with opaque orthography were selected because of their diverse characteristics. The first part reports a study of students from grades 2 and 3, whose home language and medium of instruction was Spanish, and were administered tests of decoding, listening, and reading comprehension. A comparison group of 49 children from Grade 2, 54 children from Grade 3, and 55 children from Grade 4, whose home language and instruction was English, were also administered tests of decoding, listening, and reading comprehension. Multiple regression analysis showed that approximately 60% of the variance in reading comprehension of Spanish participants and 50% of the variance in reading comprehension of English participants were explained by decoding and listening comprehension. Furthermore, the performance of third grade Spanish participants resembled that of fourth grade English-speaking participants. In the second study, 102 Chinese students from Grade 2 and 106 students from Grade 4 were administered tasks of Chinese character recognition, reading fluency, listening, and reading comprehension. Multiple regression analyses showed character recognition and listening comprehension accounted for 25% and 42% of the variance in Chinese reading comprehension at Grades 2 and 4 respectively. These results indicate that the simple view of reading is applicable to writing systems other than that of English.
