Intensive instruction affects brain magnetic activity associated with oral word reading in children with persistent reading disabilities

Fifteen children ages 7 to 9 years who had persistent reading difficulties despite adequate instruction were provided with intensive tutorial interventions. The interventions targeted deficient phonological processing and decoding skills for 8 weeks (2 hours per day) followed by an 8-week, 1-hour-per-day intervention that focused on the development of reading fluency skills. Spatiotemporal brain activation profiles were obtained at baseline and after each 8-week intervention program using magnetoencephalography during the performance of an oral sight-word reading task. Changes in brain activity were found in the posterior part of the middle temporal gyrus (Brodmann's Area [BA] 21: increased degree of activity and reduced onset latency), the lateral occipitotemporal region (BA 19/37: decreased onset latency of activation), and the premotor cortex (increased onset latency). Overall changes associated with the intervention were primarily normalizing, as indicated by (a) increased activity in a region that is typically involved in lexical--semantic processing (BA 21) and (b) a shift in the relative timing of regional activity in temporal and frontal cortices to a pattern typically seen in unimpaired readers. These findings extend previous results in demonstrating significant changes in the spatiotemporal profile of activation associated with word reading in response to reading remediation.     

Computer-assisted instruction to prevent early reading difficulties in students at risk for dyslexia: Outcomes from two instructional approaches

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately half of the instruction was delivered by specially trained teachers to prepare students for their work on the computer, and half was delivered by the computer programs. At the end of first grade, there were no differences in student reading performance between students assigned to the different intervention conditions, but the combined-intervention students performed significantly better than control students who had been exposed to their school’s normal reading program. Significant differences were obtained for phonemic awareness, phonemic decoding, reading accuracy, rapid automatic naming, and reading comprehension. A follow-up test at the end of second grade showed a similar pattern of differences, although only differences in phonemic awareness, phonemic decoding, and rapid naming remained statistically reliable.     

Neurocognitive predictors of reading outcomes for children with reading disabilities

This study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the predictive capability of the following models: (a) an intervention and phonological processing model that included intervention group, phonological awareness, and rapid naming and (b) an additive cognitive neuropsychological model that included measures of memory, visual processes, and cognitive or intellectual functioning. Over and above the substantial explanatory power of the base model, the additive model improved classification of poor and good responders. Several of the cognitive and neuropsychological variables predicted degree of reading outcomes, even after controlling for type of intervention, phonological awareness, and rapid naming.     

A comparison of two reading interventions for children with reading disabilities

This study compared the effectiveness of two reading interventions in a public school setting. Forty-five second-grade children with reading disabilities were randomly assigned to a 6-week phonological awareness, word analogy, or math-training program. The two reading interventions differed from each other in (a) the unit of word analysis (phoneme versus onset-rime), (b) the approach to intervention (contextualized versus decontextualized), and (c) the primary domain of reading instruction (oral versus written language). Results indicate that children in both reading programs achieved significant gains in beginning reading skills, learning the specific skills taught in their respective programs, and applying what they had learned to uninstructed material on several transfer-of-learning measures, in comparison to children in the control group. For children in both reading intervention groups, the most significant mediator of growth in oral reading fluency was a child's initial level of word identification skill. Implications of these findings are that systematic, high quality reading intervention can occur in a small group, public school setting and that there are several different paths to the remediation of children with reading disabilities.     

Predicting word-level reading fluency outcomes in three contrastive groups: Remedial and computer-assisted remedial reading intervention,and mainstream instruction

The aim of the longitudinal intervention study was to build a model of predictive values of reading fluency in three contrastive reading groups: remedial and computer-assisted remedial reading intervention, and mainstream instruction, to identify the most effective type of intervention for children with different profiles of compromised pre-reading skills. The participants were 7-year-old Finnish school beginners (N = 166). Two remedial interventions took place in four weekly sessions of 45 min over a period of 28 weeks in Grade 1. For a child with deficits in the core pre-reading skills (letter knowledge, phonological awareness or rapid automatized naming), the computer-assisted remedial intervention would be the most successful in remediating reading fluency in the transparent Finnish language. Furthermore, children in the computer-assisted intervention were able to reach the average level of the mainstream children by the end of Grade 2.     

Identifying children with specific reading disabilities from listening and reading discrepancy scores

A method of identifying children with specific reading disabilities by identifying discrepancies between their reading and listening comprehension scores was validated with disabled and nondisabled readers in Grades 4, 5, and 6. The method is based on a modification of the reading comprehension subtest of the Peabody Individual Achievement Test (Dunn & Markwardt, 1970). In this modification, even-numbered sentences are read by subjects, and odd-numbered sentences are read by the test administrator as subjects listen. The features of this test that reduce demands on working memory, thereby making it suitable for the detection of a discrepancy between reading and listening comprehension in readers with disabilities, are discussed. A significant group-by-modality interaction was obtained. Children with reading disabilities scored significantly lower on reading than on listening comprehension, while nondisabled readers scored slightly higher, but not significantly so, on reading than on listening comprehension. The appropriateness of this method as a substitute for the traditional method, which is based on the detection of a discrepancy between intelligence and reading and which has recently been proscribed in certain school districts, is discussed. Issues concerning the listening comprehension skills of disabled readers are also discussed.     

Putting struggling readers on the PHAST track: a program to integrate phonological and strategy-based remedial reading instruction and maximize outcomes

PHAST (for Phonological and Strategy Training) is a research-based remedial reading program that attempts to capitalize upon current research on reading disabilities and their remediation. The focus of the program is on the primary obstacles to word identification learning and independent decoding that most disabled readers face and the steps necessary to help these children achieve independent reading skills. A framework of phonologically based remediation was used as a foundation upon which a set of flexible and effective word identification strategies were scaffolded in an integrated developmental sequence. The program uses a combination of direct instruction and dialogue-based metacognitive training, with the pedagogical emphasis shifting from an initial direct instruction, remedial focus to increasingly metacognitive-strategy-based methods. A continuum of intervention over 70 hours provides both (a) remediation of the basic phonological awareness and letter-sound-learning deficits of disabled readers and (b) specific training of five word identification strategies that offer different approaches to the decoding of unfamiliar words and exposure to different levels of subsyllabic segmentation. Explicit instruction in the application and monitoring of multiple word identification strategies and their application to text-reading activities continues throughout the PHAST Program. PHAST training provides the disabled reader with the opportunity to become a flexible reader who approaches new words in or out of context with multiple strategies and has the ability to evaluate the success of their application. The PHAST Program was developed following the controlled evaluation of its components in laboratory classroom settings and recent positive results from their sequential combination. PHAST represents a new integrated approach to programming in this area using instructional components that have already demonstrated their efficacy with children with severe reading disabilities.     

Clinical applications of the Stanford-Binet intelligence scale: Fourth edition to reading instruction of children with learning disabilities

When children are referred to psychologists for evaluation, the most useful resulting information for the classroom teacher is not a label but suggestions regarding instruction. In its present format, the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE; Thorndike, Hagen, & Sattler, 1986) lends itself to the selection of instructional strategies in reading for children with learning problems. The data on cognitive skills obtained from the SB:FE provide important insights into cognitive strengths and weaknesses that may be related to academic functioning. Although there is no one-to-one correspondence between scores on a particular subtest and performance in a particular academic area, clinical interpretation of SB:FE test data can help psychologists answer the question, “How do I teach him to read?”     

Early reading instruction for children with reading difficulties: meeting the needs of diverse learners

Several multiple-probe-across-participants design studies were employed to evaluate the effectiveness of a supplemental tutoring intervention using Read Well (Sprick, Howard, & Fidanque, 1998-2000). In Year 1, we conducted two studies with 7 first-, second-, and third-grade children (1 girl and 6 boys), who were classified as having learning disabilities, having attention-deficit disorder, or being English language learners and were identified by their teachers as poor readers. The results of the two studies indicated that 3 of the 5 children who received Read Well instruction showed improvement in passage fluency. Student performance on other measures of reading and comprehension was varied. Differences in student characteristics and in the amount of Read Well instruction received (2 to 7 weeks) seemed to account for the differences in performance. In Year 2, we implemented the same tutoring intervention for a longer duration (up to 16 weeks) and included 5 children in second and third grades (2 girls and 3 boys) with reading difficulties. Two of these children had previously participated in the Year 1 studies. The results indicated growth in reading, spelling, and comprehension for most children. Overall, the findings from Year 1 and 2 studies indicate the benefits of increased instructional intensity and duration for children who struggle with emerging reading skills.     

The effects of age and sublexical automaticity on reading outcomes for students with reading disabilities

For students with reading disabilities, reading fluency has proven difficult to remediate. The current study examined age‐related effects on measures of word and text‐reading outcomes, within the context of a phonologically based remedial reading program. The contribution of speeded‐reading of sublexical sound–spelling patterns to fluency outcomes was also examined. The youngest group of participants showed better outcomes on measures of word and pseudoword reading. All age groups made significant and meaningful improvements on measures of reading fluency and reading comprehension. Participants' mastery of speeded, sublexical sound–spelling reading contributed variance to fluency outcomes beyond pre‐intervention fluency scores. Practice with sublexical spelling patterns may be one important component of programs directed at remediating accuracy and fluency deficits for students with reading disabilities. What is already known about this topic

• Reading fluency has proven difficult to remediate for students with reading disabilities.
• Training with sublexical sound–spelling patterns has increased recognition of the trained patterns, but transfer has been limited.
• Young children with reading difficulties appear to have an advantage at closing the reading achievement gap; however, there are some inconsistencies in the literature.

What this paper adds

• Automaticity with sublexical patterns made a unique contribution to fluency outcomes in this sample of students with reading disabilities.
• In the context of the reading program examined, all age groups made significant and meaningful standard score gains on reading fluency.
• Young children did not score higher than the two older groups on measures of oral reading fluency or reading comprehension; bringing into question conclusions drawn from prevention versus intervention studies.

Implications for theory and practice

• Findings lend support to models of reading acquisition that emphasize multilayered, sublexical spelling–sound knowledge as important to reading fluency, beyond that of sight‐word reading efficiency.
• Including speeded practice of a broad range of sublexical sound–spelling patterns and training these to mastery deserves further study as one potential approach to improving fluency interventions for students with reading disabilities.
• We suggest that this sublexical training may mimic reading practice in terms of building orthographic representations that support fluent reading.

     

Comprehensive reading instruction for students with intellectual disabilities: Findings from the first three years of a longitudinal study

This longitudinal experimental study investigated the reading progress of students with IQs ranging from 40 to 69 (i.e., range for students with mild or moderate mental retardation or intellectual disabilities [ID]) across at least two academic years, as well as the effectiveness of a comprehensive reading intervention for these students across the same period of time. Participants were 59 elementary students who were randomly placed into treatment and contrast groups. Students in the treatment condition received daily, comprehensive reading instruction in small groups of 1–4 students for 40–50 minutes per session across two or three academic years. Measures of phonemic awareness, phonics, word recognition, comprehension, and oral language were included. Findings indicate that students with IQs in the ID range made significant progress on multiple standardized measures of reading. Furthermore, significant differences between the treatment group and contrast group were found on several measures, including progress‐monitoring measures of phoneme segmentation, phonics, and oral reading fluency. Results demonstrate that, on average, students with ID, even those with IQs in the moderate range, learn basic reading skills given consistent, explicit, and comprehensive reading instruction across an extended period of time. © 2010 Wiley Periodicals, Inc.     

Academic responding during instruction and reading outcomes for kindergarten students at-risk for reading difficulties

The purpose of this study was to investigate the academic responding of students at-risk for reading difficulties in beginning reading instruction. Opportunities for kindergarten students at-risk for reading difficulties to respond academically during teacher-facilitated reading instruction in the general education classroom were examined in relation to student reading achievement as well as social behaviors. Student academic responding during teacher-facilitated instruction significantly predicted end of year reading achievement. Teacher perceptions of students’ social skills (positive correlation) and problem behaviors (negative correlation) were significantly correlated with academic responding. When academic responding and teacher perceptions of social behaviors were examined together, only teacher perceptions of academic competence and problem behaviors predicted spring outcomes.     

Reading fluency: implications for the assessment of children with reading disabilities

The current investigation explored the diagnostic utility of reading fluency measures in the identification of children with reading disabilities. Participants were 50 children referred to a university-based clinic because of suspected reading problems and/or a prior diagnosis of dyslexia, where children completed a battery of standardized intellectual, reading achievement, and processing measures. Within this clinical sample, a group of children were identified that exhibited specific deficits in their reading fluency skills with concurrent deficits in rapid naming speed and reading comprehension. This group of children would not have been identified as having a reading disability according to assessment of single word reading skills alone, suggesting that it is essential to assess reading fluency in addition to word reading because failure to do so may result in the under-identification of children with reading disabilities.     

Computer-based reading and spelling practice for children with learning disabilities.

To examine the effects of computer-based reading and spelling practice on the development of reading and spelling skills, a pretest-training-posttest experiment was conducted in The Netherlands. Eleven girls and 17 boys with written language disorders (on the average, 9 years, 7 months old and performing 2 grades below age expectancy) practiced hard-to-read words under three conditions: reading from the computer screen, copying from the screen, and writing from memory after presentation on the screen. For all words, whole-word sound was available on call during practice. To assess learning effects, both a dictation and a read-aloud task were administered in which nonpracticed control words were also presented. During training, the computer kept record of several aspects of the pupils' learning behavior. It was found that copying words from the screen resulted in significantly fewer spelling errors on the posttest than writing words from memory, and that both forms of spelling practice led to fewer spelling errors than only reading words during practice. All three forms of practice improved to the same degree both the accuracy and fluency of reading the practiced words aloud. The way in which spelling and reading practice, in combination with speech feedback, support the development of phonological skills in children with written language disorders is highlighted in the discussion.     

Language abilities and progress in a direct instruction reading program for students with learning disabilities

Direct instruction reading programs have been found to be a successful way to teach reading to many, but not all, students with learning disabilities. This study investigated whether reading improvement for students with learning disabilities receiving reading instruction through a direct instruction reading program might be related to their language abilities. The reading progress of 26 students (19 male, 7 female), 7 to 10 years old, was measured over 2 years. In addition, phonological and syntactic abilities were assessed. The results indicated that phonological ability was related to progress in word attack skills and that syntactic ability was related to improvement in comprehension skills. These results have implications for the reading instruction of students with learning disabilities.     

Comparing two teacher development programs for innovating reading comprehension instruction with regard to teachers’ experiences and student outcomes

This study compared a year-round intensive coaching of teachers (35 h) with a restricted in-service course (13 h), designed on the basis of research-based components of effective professional development of teachers. Both courses were developed to innovate reading comprehension instruction in elementary schools. Fourteen second- and 16 fifth-grade teachers participated. Results indicated that both conditions were equally effective in changing students’ reading comprehension, reading fluency, reading strategy use, and self-efficacy perceptions. Teachers’ experiences with the professional development course were also comparable in both conditions. A significant point of difference indicated; however, that teachers attending the restricted in-service course experienced more workload with regard to settling in the innovations.     

Code-oriented instruction for kindergarten students at risk for reading difficulties: a replication and comparison of instructional groupings

The purposes of this study were to replicate previous research on phonics-based tutoring in kindergarten and to compare treatment effects for students who received individual instruction compared to instruction in dyads. Thirty classroom teachers from 13 urban elementary schools referred at-risk students for participation. Students who met screening criteria were quasi-randomly assigned, within classroom, to one of three conditions: individual tutoring (n = 22), tutoring in dyads (n = 32), or no tutoring (n = 22, classroom instruction only). Twenty-one paraeducators provided 18 weeks of explicit instruction in phonemic skills and the alphabetic code to students during the latter half of kindergarten. Multilevel model results showed that tutored students outperformed non-tutored controls on posttest measures of phonological awareness, word reading accuracy, oral reading fluency, spelling, and comprehension. However, no significant differences were found between the two tutored groups on any measure, suggesting that code-oriented tutoring for pairs of students is a viable alternative to the gold standard of individual instruction.     

Self-concept and IQ as predictors of remedial success in children with learning disabilities

Twenty-five children with learning disabilities (LD) in the auditory-linguistic realm participated in the present study over two academic years. The purpose of the experiment was to test whether IQ and self-concept were significant predictors of learning ability. IQ was found to have no relationship to the children's learning ability, whereas self-concept predicted patterns of successful achievement in spelling, arithmetic, and written language, but not in visual word recognition. The results were interpreted as support for the "specificity" presumption in LD, but also as support for the importance of self-concept as possibly a primary cause of academic underachievement. The paper develops a remedial model of LD that accounts both for the interplay of self-concept and cognition in learning and for the fundamental implications of the specificity principle.
