The dimensionality of phonological awareness: An application of item response theory.

A battery of 7 tasks composed of 105 items thought to measure phonological awareness skills was administered to 945 children in kindergarten through 2nd grade. Results from confirmatory factor analysis at the task level and modified parallel analysis at the item level indicated that performance on these tasks was well represented by a single latent dimension. A 2-parameter logistic item response (IRT) model was also fit to the performance on the 105 items. Information obtained from the IRT model demonstrated that the tasks varied in the information they provided about a child's phonological awareness skills. These results showed that phonological awareness, as measured by these tasks, appears to be well represented as a unidimensional construct, but the tasks best suited to measure phonological awareness vary across development.

Dissociation of sensitivity and response bias in children with attention deficit/hyperactivity disorder during central auditory masking.

Forty-three children (ages 7.0-14.5 years old) with and without attention deficit/hyperactivity disorder (ADHD), combined type had thresholds for detection of a 500-Hz pure tone estimated with and without a noise masker in the contralateral ear. The ear receiving the signal in the masked condition was varied randomly. A single-interval maximum-likelihood method estimated thresholds and false-alarm rate. Whereas the increase in threshold in children with ADHD in the presence of contralateral masking was comparable with controls, the increase in false-alarm rate was significantly greater. This dissociation between changes in sensitivity and response bias in the presence of masking noise supports suggestions that children with ADHD have difficulty inhibiting maladaptive responses and indicates that this deficit is quantifiable using psychoacoustic methods.

The role of instruction in learning to read: Preventing reading failure in at-risk children.

First and 2nd graders (N?=?285) receiving Title 1 services received 1 of 3 kinds of classroom reading programs: direct instruction in letter–sound correspondences practiced in decodable text (direct code); less direct instruction in systematic sound–spelling patterns embedded in connected text (embedded code); and implicit instruction in the alphabetic code while reading connected text (implicit code). Children receiving direct code instruction improved in word reading at a faster rate and had higher word-recognition skills than those receiving implicit code instruction. Effects of instructional group on word recognition were moderated by initial levels of phonological processing and were most apparent in children with poorer initial phonological processing skills. Group differences in reading comprehension paralleled those for word recognition but were less robust. Groups did not differ in spelling achievement or in vocabulary growth. Results show advantages for reading instructional programs that emphasize explicit instruction in the alphabetic principle for at-risk children.

Contextual effects of bilingual programs on beginning reading.

This study of 1,338 Spanish-speaking 1st graders examined contextual effects of bilingual programs on reading comprehension and the effect of language of instruction within these contexts. The study included 128 classrooms in 32 schools located in border Texas and in urban Texas and California. These classrooms used either English immersion or Spanish maintenance bilingual programs. Detailed observations of teachers' instructional language were made, sampled within the year. The analyses allowed classroom-level differences to be separated from student-level differences, and for Spanish and English passage comprehension to be considered simultaneously. While mean differences between programs were reduced for English passage comprehension, maintenance programs still outperformed immersion programs in Spanish. Results also indicated large program and locale covariance differences at the classroom level, implying important differences in how these programs operate in these locales.

The contributions of phonological awareness and letter-name knowledge to letter-sound acquisition—a cross-classified multilevel model approach.

In the present study, we investigated critical factors in letter-sound acquisition (i.e., letter-name knowledge and phonological awareness) with data from 653 English-speaking kindergartners in the beginning of the year. We examined (a) the contribution of phonological awareness to facilitating letter-sound acquisition from letter names and (b) the probabilities of letter-sound acquisition as a function of letter characteristics (i.e., consonant–vowel letters, vowel–consonant letters, letters with no sound cues, and vowel letters). The results show that letter-name knowledge had a large impact on letter-sound acquisition. Phonological awareness had a larger effect on letter-sound knowledge when letter names were known than when letter names were unknown. Furthermore, students were more likely to know the sounds of consonant–vowel letters (e.g., b and d) than vowel–consonant letters (e.g., l and m) and letters with no sound cues (e.g., h and y) when the letter name was known and phonological awareness was accounted for. Sounds were least likely to be known for letters with no sound cues, but reliable differences from other groups of letters depended on students' levels of phonological awareness and letter-name knowledge.

Relation of phonological and orthographic processing to early reading: Comparing two approaches to regression-based, reading-level-match designs.

K. E. Stanovich and L. Siegel (see record 81-030191) introduced regression-based logic to the reading-level-match design by statistically matching children with reading disabilities, with and without discrepancies in IQ, to normal-reading children on the basis of grade-adjusted decoding scores. The authors replicated this approach but contrasted it with statistical matches using w scores, which are Rasch-scaled decoding scores based on a common metric regardless of age or grade. No differences were found in cognitive skills between children whose reading performance was discrepant and not discrepant with IQ, regardless of whether age-adjusted decoding scores or w scores were used. Matching on w scores did not result in the phonological and orthographic tradeoffs seen when standardized scores were used. The orthographic-decoding relationship was nonlinear, with little functional relation between the skills at low levels of decoding. These results question the conclusion that orthographic skills are compensatory for reading-disabled children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Kindergarten Prediction of Reading Skills: A Longitudinal Comparative Analysis.

There is considerable focus in public policy on screening children for reading difficulties. Sixty years of research have not resolved questions of what constructs assessed in kindergarten best predict subsequent reading outcomes. This study assessed the relative importance of multiple measures obtained in a kindergarten sample for the prediction of reading outcomes at the end of 1st and 2nd grades. Analyses revealed that measures of phonological awareness, letter sound knowledge, and naming speed consistently accounted for the unique variance across reading outcomes whereas measures of perceptual skills and oral language and vocabulary did not. These results show that measures of letter name and letter sound knowledge, naming speed, and phonological awareness are good predictors of multiple reading outcomes in Grades 1 and 2.

Pictures and words: Spanish and English vocabulary in classrooms.

The current study evaluated the relation between Spanish and English vocabulary. Whereas previously reported correlations have revealed strong differences among types of vocabulary measures used and the ages of the students tested, no prior study had used a multilevel model to control for classroom-level differences. The current study used multiple measures of vocabulary—picture vocabulary and narrative production tasks—in multilevel models of 1,300 Spanish-speaking students in 247 kindergarten and 1st-grade classrooms in English immersion and bilingual transitional programs. The current results highlight the need to separate classroom effects from student effects, since for vocabulary measures, student-level correlations were strongly biased toward zero when classroom-level correlations were opposite in direction from student-level correlations. Most important, the current results support a strong distinction between types of vocabulary measure (e.g., picture vs. narrative) and suggest sizable influence of instruction for questions of bilingual performance.

Does growth rate in oral reading fluency matter in predicting reading comprehension achievement?

In this study, we examined the relationship of growth trajectories of oral reading fluency, vocabulary, phonological awareness, letter-naming fluency, and nonsense word reading fluency from 1st grade to 3rd grade with reading comprehension in 1st, 2nd, and 3rd grades. Data from 12,536 children who were followed from kindergarten to 3rd grade longitudinally were used. These children were administered Dynamic Indicators of Basic Early Literacy Skills subtests, Peabody Picture Vocabulary Test—Third Edition, and reading comprehension (Stanford Achievement Test, 10th ed.) tasks multiple times in each year. Students' initial status and rate of growth in each predictor within each grade were estimated using individual growth modeling. These estimates were then used as predictors in dominance regression analyses to examine relative contributions that the predictors made to the outcome: reading comprehension. Among the 1st-grade predictors, individual differences in growth rate in oral reading fluency in 1st grade, followed by vocabulary skills and the autoregressive effect of reading comprehension, made the most contribution to reading comprehension in 3rd grade. Among the 2nd- and 3rd-grade predictors, children's initial status in oral reading fluency had the strongest relationships with their reading comprehension skills in 3rd grade.
