Code-oriented instruction for kindergarten students at risk for reading difficulties: A randomized field trial with paraeducator implementers.

The purpose of this study was to evaluate the effectiveness of code-oriented supplemental instruction for kindergarten students at risk for reading difficulties. Paraeducators were trained to provide 18 weeks of explicit instruction in phonemic skills and the alphabetic code. Students identified by their teachers meeting study eligibility criteria were randomly assigned to 2 groups: individual supplemental instruction and control. Students were pretested in December, midtested, and posttested in May-June of kindergarten. At posttest, treatment students significantly outperformed controls on measures of reading accuracy, reading efficiency, oral reading fluency, and developmental spelling. Treatment students had significantly higher linear growth rates in phonemic awareness and alphabetic knowledge during the kindergarten treatment. At a 1-year follow-up, significant group differences remained in reading accuracy and efficiency. Ethical challenges of longitudinal intervention research are discussed. Findings have policy implications for making supplemental instruction in critical early reading skills available. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Story retell: A fluency-based indicator of reading comprehension.

This article presents a fluency-based measure of reading comprehension. A part of the Vitals Indicators of Progress (VIP) system, the measure outlined here represents an alternate form to the retell-fluency measure in the Dynamic Indicators of Basic Early Literacy System (DIBELS). Measures of retell fluency provide an efficient, fluency-based tool for teachers to use in identifying the handful of children whose oral reading fluency may not adequately represent comprehension. When used in tandem with oral fluency measures, retell measures provide a vehicle for more reliably targeting classroom and school-level resources and for maximizing the efficiency and effectiveness of early reading instruction.

Effects of Viewing the Television Program Between the Lions on the Emergent Literacy Skills of Young Children.

Does viewing Between the Lions, an educational television series featuring literacy instruction, improve the emergent literacy skills of kindergarten and first-grade children? Do improvements vary as a function of the child's initial reading risk status? In this study, higher word recognition and standardized reading test scores were noted for all viewers compared with nonviewers. In addition, significantly higher means and accelerated slopes for phonemic awareness and letter-sound tasks were found for viewers compared with nonviewers. Even so, improvements in literacy skills (i.e., speech to print, word building, concepts of print) varied, mostly favoring moderately at-risk to not-at-risk kindergarten children who viewed the program. Kindergarten children at great risk and first graders did not benefit as much from the program. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Development of Reading in Children Who Speak English as a Second Language.

Patterns of reading development were examined in native English-speaking (L1) children and children who spoke English as a second language (ESL). Participants were 978 (790 L1 speakers and 188 ESL speakers) Grade 2 children involved in a longitudinal study that began in kindergarten. In kindergarten and Grade 2, participants completed standardized and experimental measures including reading, spelling, phonological processing, and memory. All children received phonological awareness instruction in kindergarten and phonics instruction in Grade 1. By the end of Grade 2, the ESL speakers' reading skills were comparable to those of L1 speakers, and ESL speakers even outperformed L1 speakers on several measures. The findings demonstrate that a model of early identification and intervention for children at risk is beneficial for ESL speakers and also suggest that the effects of bilingualism on the acquisition of early reading skills are not negative and may be positive.

Modeling oral reading fluency development in Latino students: A longitudinal study across second and third grade.

This study examines growth in oral reading fluency across 2nd and 3rd grade for Latino students grouped in 3 English proficiency levels: students receiving English as a second language (ESL) services (n = 2,182), students exited from ESL services (n = 965), and students never designated as needing services (n = 1,857). An important focus was to learn whether, within these 3 groups, proficiency levels and growth were reliably related to special education status. Using hierarchical linear modeling, the authors compared proficiency levels and growth in oral reading fluency in English between and within groups and then to state reading benchmarks. Findings indicate that oral reading fluency scores reliably distinguished between students with learning disabilities and typically developing students within each group (effect sizes ranging from 0.96 to 1.51). The growth trajectory included a significant quadratic trend (generally slowing over time). These findings support the effectiveness of using oral reading fluency in English to screen and monitor reading progress under Response to Intervention models, but also suggest caution in interpreting oral reading fluency data as part of the process in identifying students with learning disabilities.

Longitudinal predictors of reading and math trajectories through middle school for African American versus Caucasian students across two samples.

This study's primary purpose was to examine the relative contribution of social-behavioral predictors to reading and math skills. The study expands on Duncan et al.'s (2007) work by using longitudinal methodology from the National Institute of Child Health and Human Development's Study of Child Care and Youth Development (SECCYD) and the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (ECLS-K) databases, and by focusing on potential differences in patterns of early predictors of later reading and math trajectories for African American versus Caucasian students. Predictor measures were selected at kindergarten, and the outcomes included standardized reading and math scores obtained from Grades 1, 3, 5, and 9 for the SECCYD sample, and Grades 3, 5, and 8 for the ECLS-K sample. Consistent with Duncan et al.'s findings, results reflect the relative contributions of early reading and math skills to later functioning in these respective academic domains for both samples, and there are indications for the importance of early expressive language skills to both reading and math in the SECCYD sample. Findings related to the power of social-behavioral predictors, however, are not consistent across samples. Although the SECCYD sample evidenced no such predictors, several interactions in the ECLS-K sample suggested the moderating effects of early ratings of aggressive behaviors and internalizing behaviors on later reading and math for African American students. The moderating effects of early teacher ratings of attention and internalizing behaviors for African American students as compared with Caucasian students in later math growth also were noted. The importance of early social-behavioral functions as related to later academic skills remains an important area of inquiry. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Fine motor skills and early comprehension of the world: Two new school readiness indicators.

Duncan et al. (2007) presented a new methodology for identifying kindergarten readiness factors and quantifying their importance by determining which of children's developing skills measured around kindergarten entrance would predict later reading and math achievement. This article extends Duncan et al.'s work to identify kindergarten readiness factors with 6 longitudinal data sets. Their results identified kindergarten math and reading readiness and attention as the primary long-term predictors but found no effects from social skills or internalizing and externalizing behavior. We incorporated motor skills measures from 3 of the data sets and found that fine motor skills are an additional strong predictor of later achievement. Using one of the data sets, we also predicted later science scores and incorporated an additional early test of general knowledge of the social and physical world as a predictor. We found that the test of general knowledge was by far the strongest predictor of science and reading and also contributed significantly to predicting later math, making the content of this test another important kindergarten readiness indicator. Together, attention, fine motor skills, and general knowledge are much stronger overall predictors of later math, reading, and science scores than early math and reading scores alone.

Early identification of reading difficulties using heterogeneous developmental trajectories.

Serious conceptual and procedural problems associated with current diagnostic methods call for alternative approaches to assessing and diagnosing students with reading problems. This study presents a new analytic model to improve the classification and prediction of children's reading development. Growth mixture modeling was used to identify the presence of 10 different heterogeneous developmental patterns. In all, 411 children in kindergarten through Grade 2 from 3 elementary schools in Texas were administered measures of phonological awareness, word recognition, and rapid naming skills 4 times a year. The mean ages were 5.8 years (SD = 0.35) for the kindergartners, 6.9 years (SD = 0.39) for Grade 1, and 8.0 years (SD = 0.43) for Grade 2; the percentage of boys was 50%. The results indicate that precursor reading skills such as phonological awareness and rapid naming are highly predictive of word reading (word recognition) and that developmental profiles formed in kindergarten are directly associated with development in Grades 1 and 2. Students identified as having reading-related difficulties in kindergarten exhibited slower development of word recognition skills in subsequent years of the study.

Literacy development in early French immersion programs.

Research findings on reading acquisition in early French immersion programs are reviewed. Findings on general reading outcomes, in English and French, are reviewed first, followed by a review of reading outcomes for students who are at risk for reading difficulty because of below-average levels of academic ability, poor first language abilities, disadvantaged socioeconomic backgrounds, and minority language status. There follows a review of studies on individual differences in reading outcomes, including research on students with or at risk for reading difficulties, and on interventions to support students with reading difficulties in immersion. Conclusions along with suggestions for future research are offered. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Growing readers: A hierarchical linear model of children's reading growth during the first 2 years of school.

Using the first 4 waves of data from the Early Childhood Longitudinal Study-Kindergarten cohort (ECLS-K), this piecewise 3-level (time-student-school) growth-curve model provides a portrait of students' reading growth over the first 2 years of school. On average, students make much greater reading gains in 1st grade than they do in kindergarten. First-grade monthly reading growth averages 2.65 points per month, whereas kindergarteners make approximately 1.67 points of reading growth per month. Student-level variables (including socioeconomic status, ethnicity, kindergarten entry age, and gender) were better able to explain between-schools variability in students' initial reading scores and students' reading growth than school-level variables (percentage of minority students, percentage of free-lunch students, and sector). Although socioeconomic status had a minimal impact on reading growth while school was in session, it had a larger impact on summer reading growth. These results suggest that between-schools differences in achievement are largely explained by the differences in school clientele, rather than differences in instruction or resource allocation. These results also underscore the potential importance of preschool and summer programs for low-socioeconomic status children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Improving the efficacy of first grade reading screening: An investigation of word identification fluency with other early literacy indicators.

This study investigated the accuracy of several early literacy measures that have been used in research and practice for first grade reading screening. A set of measures, Word Identification Fluency (WIF), Letter Naming Fluency, Phoneme Segmentation Fluency, and Nonsense Word Fluency, were administered as screening measures with 138 first grade students in the fall of the school year. Reading skills were assessed at the end of first grade using Oral Reading Fluency, the Test of Word Reading Efficiency (Sight Word Efficiency and Phonemic Decoding Efficiency), reading Maze, and a latent variable composite. Analyses compared the accuracy at which each screening measure, as well as combinations of screening measures, classified students according to successful or unsuccessful reading outcomes at the end of the year. Receiver operating characteristic curve analyses indicated that when compared with other single screening measures, WIF tended to demonstrate the strongest overall classification accuracy. With levels of sensitivity held constant at .90, combining screening measures with WIF using predicted probabilities from logistic regression analyses resulted in modest improvements in accuracy by reducing the number of false positives. More measures were not always better, however, as models of two or three measures were as accurate as models consisting of all measures. Overall results provided support for WIF as a starting point for first grade reading screening, whereby additional steps might be taken to reduce false positives.

Early predictors of biliteracy development in children in French immersion: A 4-year longitudinal study.

English language predictors of English and French reading development were investigated in a group of 140 children who were enrolled in French immersion programs. Children were first tested in kindergarten, and their reading achievement was tested yearly in both English and French from Grades 1 to 3, with word-level and passage-level measures that assessed accuracy as well as fluency. Hierarchical linear modeling was used to examine which English variables predicted Grade 3 outcomes and growth rates in English and French, and to determine the set of predictors that accounted for the most variance in outcomes and growth rates in English and French reading. The variables that predicted English reading development were consistent with studies of monolingual English children, even though participants were concurrently learning to read in French. Our findings provide evidence that at least some of the skills that play a role in learning to read are general cognitive and linguistic skills that transfer across languages. Phonological awareness, letter-sound knowledge, rapid automatized naming, and grammatical ability in English were able to predict reading ability in French. In contrast, English receptive vocabulary was a language-specific predictor. These findings demonstrate that first-language measures can be useful in the early identification of children at risk for difficulty in learning to read in a second language.

Examining Ethnic, Gender, Language, and Socioeconomic Bias in Oral Reading Fluency Scores among Caucasian and Hispanic Students.

Research has demonstrated that oral reading fluency probes are reliable and valid for indexing reading achievement. If these probes are to be used for decision making, bias must be examined for various factors, including ethnicity, gender, language background, and socioeconomic status. Data from nearly 4,000 Caucasian and Hispanic students in grades one through three were used to examine potential bias in oral reading fluency scores predicting Stanford Achievement Test-Ninth Edition (SAT-9; Harcourt Brace & Co., 1997a, 1997b) Total Reading scores. Using a series of hierarchical multiple regression models, bias was first examined using concurrent SAT-9 scores as the criterion and then examined using subsequent SAT-9 scores as the criterion. The results reveal that it is the combination of factors, not any one in isolation, that significantly contributes to intercept bias findings. Overall, home language emerged as the strongest factor influencing bias in the prediction of SAT-9 scores from oral reading fluency scores. The implications of these findings are discussed as related to current and proposed uses of oral reading fluency probes. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Growth in reading skills of children from diverse linguistic backgrounds: Findings from a 5-year longitudinal study.

This article reports on the results of a longitudinal investigation of the reading development of a sample of 824 children (406 girls, 418 boys). The sample included 689 native English-speaking (L1) children and 135 English-language learners (ELLs) representing 33 different native languages. In kindergarten and 4th grade, children's word reading, spelling, phonological processing, syntactic awareness, and working memory skills were assessed with standardized and experimental measures. In addition, word reading was assessed from kindergarten through 4th grade, and reading comprehension in 4th grade. Comparisons of reading skills between the ELLs and the L1 speakers demonstrated that despite slightly lower performance of the ELLs on several kindergarten tasks, differences at 4th grade were negligible. Fourth-grade word reading was predicted by the same kindergarten tasks for both language groups, and prediction of reading comprehension differed by only 1 task. Finally, the trajectory of word reading was nonlinear for both groups, although predictors of this trajectory differed between groups. The findings suggest that early identification models established through research with L1 speakers are appropriate for identifying ELLs at risk for reading difficulties.

Resilient readers? University students who are poor recoders but sometimes good text comprehenders.

The authors screened 194 university students to determine whether some could comprehend text well despite very poor recoding skills, measured by pseudoword reading. Most of the 17 poorest recoders had never been identified as reading disabled. We classified 6 poor recoders as "resilient readers" because their text comprehension scores were average or above, relative to the sample as a whole. They were indistinguishable from 6 matched typical readers on measures of text comprehension derived from oral-reading think-aloud protocols. There was no evidence that the resilient readers relied on superior verbal ability or working memory to compensate for poor recoding. The resilient readers were poor at spelling, reading isolated words, and reading text rapidly, but they showed adequate phonemic awareness.

What's meaning got to do with it: The role of vocabulary in word reading and reading comprehension.

There is at present no clear consensus as to the nature of the relations between oral vocabulary and specific literacy skills. The present study distinguished between vocabulary breadth and depth of vocabulary knowledge to better explain the role of oral vocabulary in various reading skills. A sample of 60 typically developing Grade 4 students was assessed on measures of receptive and expressive vocabulary breadth, depth of vocabulary knowledge, decoding, visual word recognition, and reading comprehension. Concurrent analyses revealed that each distinct reading skill was related to the vocabulary measures in a unique manner. Receptive vocabulary breadth was the only oral vocabulary variable that predicted decoding performance after controlling for age and nonverbal intelligence. In contrast, expressive vocabulary breadth predicted visual word recognition, whereas depth of vocabulary knowledge predicted reading comprehension. The results are discussed in terms of interrelations between phonological and semantic factors in the acquisition of distinct reading skills.

Evaluation of the integrity of the hypothalamic-pituitary-adrenal axis by insulin hypoglycemia test

We retrospectively reviewed dynamic ACTH and cortisol responses to insulin hypoglycemia in 193 subjects with suspected ACTH deficiency to ascertain the predictive values of various diagnostic criteria. Based on the achievement of a peak cortisol level of 18 micrograms/dL or above, 133 subjects were classified as having an intact hypothalamic-pituitary-adrenal (HPA) axis, and 60 subjects were determined to have ACTH deficiency. Baseline and peak cortisol concentrations were strongly correlated (r = 0.63; P < 0.0001). Peak cortisol increased in parallel to ACTH increments, but plateaued at approximately 22 micrograms/dL at peak ACTH levels above approximately 75 pg/mL (r = 0.61; P < 0.0001). Basal cortisol values above 17 micrograms/dL or below 4 micrograms/dL were highly predictive of an intact or impaired HPA axis, respectively, but intermediate values had only limited sensitivity and specificity. The criteria of HPA axis integrity, defined as an increment in plasma cortisol of more than 7 micrograms/dL above the baseline or as a doubling of the baseline cortisol value, were associated with high false positive and false negative rates. We conclude that 1) the baseline morning serum cortisol concentration has very limited predictive power in differentiating between normal and impaired HPA function; 2) the use of criteria based on incremental changes in serum cortisol from baseline leads to unacceptably high false positive and false negative rates; and 3) insulin hypoglycemia is still the best indicator of the integrity of the response of the HPA axis to stress.     

Assessment for instructional decisions: Toward a proactive/prevention model of decision-making for early literacy skills.

Uses a case study to illustrate a problem solving model of educational decision making using Dynamic Indicators of Basic Early Literacy Skills (DIBELS) measures to provide a local normative context, to monitor progress, and to evaluate the effects of interventions on an individual basis. The linkage between assessment information and educational decisions is demonstrated in the 4 phases of the problem solving model: Problem Identification, Problem Validation, Exploring Solutions, and Evaluating Solutions. For the case study, the problem solving model using DIBELS measures of phonological awareness provided important information regarding who to target for intervention, what skill to target in the intervention, and which interventions were effective. Using DIBELS measures of early literacy skills, educators can intervene early to prevent serious reading difficulties later. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Instructional approaches that significantly increase reading comprehension.

The purpose of this study was to analyze the effects of the most widely used literacy instructional approaches on the reading comprehension of Grade 2–6 students. Participants (N = 660) were enrolled in 4 districts in the United States; 53% were male (n = 348) and 47% were female (n = 312); 51% were Caucasian (n = 338), 23% were African American (n = 149), 21% were Hispanic (n = 138), and 5% represented other ethnic backgrounds (n = 35). Sixty-two percent came from low to low-middle socioeconomic status schools, and 38% came from middle to high socioeconomic status schools. The study was a quantified experimental versus controlled group comparison. Analyses of variance were used to determine the differences between literacy scores. Two-level hierarchical linear modeling analyses were used to examine the effects of school variables on academic achievement. The highest comprehension scores for all populations occurred through three approaches. When struggling readers received 20 min of instruction with 1 of these 3 approaches, their literacy growth was equal to or greater than that of their peers. Implications are that treatments using classroom books produced significantly higher comprehension scores than workbook practice or extending basal treatments.

Oral reading rates of second-grade students.

The importance of reading fluently is widely recognized in school effectiveness, reform, and improvement efforts of the educational community, yet there are few large-scale, structured assessments of the progression of students' reading rates over time. This study documented 2nd-grade students' oral reading rates on the basis of fall, winter, and spring assessments. Using growth curve analysis, we identified models for a sample (n = 5,796) of students in 79 schools in a large urban school district in the United States. We found that, although school characteristics were significant predictors of the children's initial oral reading status, they were mostly not significant predictors of their reading rate over time. At the individual level, girls had a better performance than did boys in reading achievement testing, and no statistically significant difference was noted between boys and girls in their growth rates during the 2nd grade. On the other hand, special education children not only achieved less than did non-special education children in oral reading but also evidenced a significantly lower rate of increase. The trustworthiness of “at risk” and “low risk” instructional recommendations on the basis of oral reading rates was high. We discuss these findings in light of the existing research on reading fluency. Our findings have implications for research and instruction for fluency and literacy development of both fluent and nonfluent readers. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
