Visible Learning: A Synthesis of Over 800 Meta-Analyses Relating to Achievement

The lexical quality hypothesis (LQH) claims that variation in the quality of word representations has consequences for reading skill, including comprehension. High lexical quality includes well-specified and partly redundant representations of form (orthography and phonology) and flexible representations of meaning, allowing for rapid and reliable meaning retrieval. Low-quality representations lead to specific word-related problems in comprehension. Six lines of research on adult readers demonstrate some of the implications of the LQH. First, large-scale correlational results show the general interdependence of comprehension and lexical skill while identifying disassociations that allow focus on comprehension-specific skill. Second, word-level semantic processing studies show comprehension skill differences in the time course of form-meaning confusions. Studies of rare vocabulary learning using event-related potentials (ERPs) show that, third, skilled comprehenders learn new words more effectively and sho...

Reading Ability: Lexical Quality to Comprehension

The authors report a systematic meta-analytic review of the relationships among 3 of the most widely studied measures of children's phonological skills (phonemic awareness, rime awareness, and verbal short-term memory) and children's word reading skills The review included both extreme group studies and correlational studies with unselected samples (235 studies were included, and 995 effect sizes were calculated) Results from extreme group comparisons indicated that children with dyslexia show a large deficit on phonemic awareness in relation to typically developing children of the same age (pooled effect size estimate: -137) and children matched on reading level (pooled effect size estimate: -057) There were significantly smaller group deficits on both rime awareness and verbal short-term memory (pooled effect size estimates: rime skills in relation to age-matched controls, -093, and reading-level controls, -037; verbal short-term memory skills in relation to age-matched controls, -071, and reading-level controls, -009) Analyses of studies of unselected samples showed that phonemic awareness was the strongest correlate of individual differences in word reading ability and that this effect remained reliable after controlling for variations in both verbal short-term memory and rime awareness These findings support the pivotal role of phonemic awareness as a predictor of individual differences in reading development We discuss whether such a relationship is a causal one and the implications of research in this area for current approaches to the teaching of reading and interventions for children with reading difficulties

Phonological skills and their role in learning to read: A meta-analytic review.

In this critique of current reading research and practice, the author contends that the extreme ambiguity of English spelling-sound correspondence has confined reading science to an insular, Anglocentric research agenda addressing theoretical and applied issues with limited relevance for a universal science of reading. The unique problems posed by this "outlier" orthography, the author argues, have focused disproportionate attention on oral reading accuracy at the expense of silent reading, meaning access, and fluency, and have significantly distorted theorizing with regard to many issues-including phonological awareness, early reading instruction, the architecture of stage models of reading development, the definition and remediation of reading disability, and the role of lexical-semantic and supralexical information in word recognition. The dominant theoretical paradigm in contemporary (word) reading research--the Coltheart/Baron dual-route model (see, e.g., J. Baron, 1977; M. Coltheart, 1978) and, in large measure, its connectionist rivals--arose largely in response to English spelling-sound obtuseness. The model accounts for a range of English-language findings, but it is ill-equipped to serve the interests of a universal science of reading chiefly because it overlooks a fundamental unfamiliar-to-familiar/novice-to-expert dualism applicable to all words and readers in all orthographies.

On the Anglocentricities of current reading research and practice: the perils of overreliance on an "outlier" orthography.

Alphabetic orthographies differ in the transparency of their letter-sound mappings, with English orthography being less transparent than other alphabetic scripts. The outlier status of English has led scientists to question the generality of findings based on English-language studies. We investigated the role of phonological awareness, memory, vocabulary, rapid naming, and nonverbal intelligence in reading performance across five languages lying at differing positions along a transparency continuum (Finnish, Hungarian, Dutch, Portuguese, and French). Results from a sample of 1,265 children in Grade 2 showed that phonological awareness was the main factor associated with reading performance in each language. However, its impact was modulated by the transparency of the orthography, being stronger in less transparent orthographies. The influence of rapid naming was rather weak and limited to reading and decoding speed. Most predictors of reading performance were relatively universal across these alphabetic languages, although their precise weight varied systematically as a function of script transparency.

Orthographic Depth and Its Impact on Universal Predictors of Reading A Cross-Language Investigation

This study provides a meta-analysis of the correlational literature on measures of phonological awareness, rapid naming, reading, and related abilities. Correlations (N = 2,257) were corrected for sample size, restriction in range, and attenuation from 49 independent samples. Correlations between phonological awareness (PA) and rapid naming (RAN) were low (.38) and loaded on different factors. PA and RAN were moderately correlated with real-word reading (.48 and .46, respectively). Other findings were that (a) real-word reading was correlated best (r values were .60 to .80) with spelling and pseudoword reading, but correlations with RAN, PA, vocabulary, orthography, IQ, and memory measures were in the low-to-moderate range (.37 to .43); and (b) correlations between reading and RAN/PA varied minimally across age groups but were weaker in poor readers than in skilled readers. The results suggested that the importance of RAN and PA measures in accounting for reading performance has been overstated.

Rapid Naming, Phonological Awareness, and Reading: A Meta-Analysis of the Correlation Evidence

There has been much discussion in the literature in recent years on the problems involved in the identification of children with reading disabilities. One of the most influential sources of knowledge in the field of learning disabilities is the National Institute of Child Health and Human Development (NICHD). This agency has typically been a major funding source for methodologically rigorous reading intervention research. Further, such research has contributed significantly to the validity of identifying children suspected of learning disabilities as “treatment resistors” (e.g. Vellutino et al., 1996). Yet, the NICHD has recently been the focus of some controversy. The purpose of this chapter was to synthesize NICHD funded research conducted over the past 10 years via a meta-analysis to determine what can be generalized from this body of research that can be applied to the identification of students with learning disabilities in reading. The results of the synthesis were that a prototypical intervention study has a mean effect size (ES) of 0.67 (SD=0.42), indicating that most interventions designed to increase reading skills were effective. The overall ES ranged, however, from 0.19 to 1.76, and therefore some criterion could be established for identifying treatment resistors. Performance below an overall ES of 0.25 was suggested as one of several criteria for identifying children with potential reading disabilities. However, this suggestion must be put in the context of intervention outcomes. The synthesis indicated that: (a) performance was more pronounced on skill or process measures (e.g. ES varies from 0.45 to 1.28 on measures of segmentation and pseudoword reading) than on measures of actual reading (ES varies from 0.17 to 0.60 on real word and comprehension measures); (b) the magnitude of effect sizes were more related to instructional activity (e.g. explicit instruction/practice) than to the content of instruction (e.g. type of phonics instruction); and (c) the bulk of intervention studies focused on a narrow range of reading behaviors (i.e. phonological awareness). Implications related to identification and sound teaching practice versus content training of reading instruction (e.g. phonological skills, comprehension skills) are discussed.
