The Use of the Regression Discontinuity Design in Tiered Intervention Research: A Pilot Study Exploring Vocabulary Instruction for At‐Risk Kindergarteners

The purpose of this article was twofold: (1) to explore the feasibility of the regression discontinuity design (RDD) in response‐to‐intervention implementation research and (2) to expand upon the limited research on vocabulary instruction for kindergarten students who are at risk for reading failure due to limited vocabularies. This pilot study employed an abbreviated, prototypical tiered instructional model to deliver vocabulary instruction to both at‐risk kindergarten students and students not at risk for reading failure. The study was designed using RDD and the data were analyzed using a regression‐based analytic model. The pros and cons of this research design, specifically in regards to learning disabilities research, is examined.     

From Professional Development to Implementation: A District's Experience Implementing Mathematics Tiered Systems of Support

This article is about a school‐district‐initiated partnership with university faculty and their effort to implement a mathematics multi‐tiered system of support (MTSS). In addition to reporting research about MTSS implementation, we describe how this district translated research into practice. We also share the perceptions of key stakeholders about implementing mathematics MTSS in their district. We found that stakeholders identified time and human capacity as barriers to implementation, while the primary facilitator to implementation was identified as the acquisition of concrete strategies and tools supporting instruction. These stakeholder perceptions have implications for other districts with limited resources attempting to implement mathematics MTSS in their buildings through professional development and coaching.     

The Common Core State Standards and Reading: Interpretations and Implications for Elementary Students with Learning Disabilities

The K‐5 reading standards within the English Language Arts Common Core State Standards provide guidance to teachers about grade level expectations for students. Though the authors of the standards acknowledge that some students may experience difficulty reaching the rigorous expectations, they explain that the standards outline a pathway to proficiency for all students, including those who struggle with literacy. Students with learning disabilities, who often have significant literacy difficulties, may face particular challenges when their instruction is framed by these standards. This article unpacks the complex K‐5 reading standards and provides a discussion of the implications for students with learning disabilities and their general and special education teachers. Examples from K‐5 lessons and recommendations for teachers and researchers are provided.     

Not Such a Simple Story: Contradictory Evidence from a Review of Story Structure Research for Students At‐Risk

The Common Core State Standards and the continued inclusion of students with learning disabilities (LD) in Tier 1 classrooms are changing how close reading of texts occurs in English Language Arts classrooms. Therefore, understanding the potential impact of literacy‐related evidence‐based practices during Tier 1 instruction that includes students with reading‐related disabilities is essential. This article reviews the research on story‐structure instruction for students with LD and at‐risk for failure. Findings across 16 studies indicate several features of strong methodological designs including random assignment and inclusion of students with LD. However, substantial limitations in the research base include contradictory outcomes, limited outcomes disaggregated for students with LD, reliance on researcher‐developed measures, a lack of instructional features to support students with LD, and limited features of feasible implementation.     

Evaluating the cost-effectiveness of the Dyslexia Pilot Project: A multitiered system of supports for early literacy

The Dyslexia Pilot Project provided funding to school districts to implement a multitiered system of support (MTSS) framework for the prevention, early identification, and early intervention of reading difficulties. This article describes the evaluation of the multiyear Dyslexia Pilot Project for students in kindergarten through Grade 2. The evaluation extended a conceptual model for evaluating the systems effects of an MTSS for reading by including a cost-effectiveness analysis. The results indicate that mean rates of improvement on Dynamic Indicators for Basic Early Literacy Skills Next curriculum-based measures for students in participating schools exceeded the expected rates of improvement based on benchmark norms. This reduction in risk precluded the need for more intensive, individualized, and costly interventions and specialized educational services. Implications of the findings and future directions are discussed.     

The Effects of Read‐Aloud Accommodations for Students With and Without Disabilities: A Meta‐Analysis

Read‐aloud accommodations have been proposed as a way to help remove barriers faced by students with disabilities in reading comprehension. Many empirical studies have examined the effects of read‐aloud accommodations; however, the results are mixed. With a variance‐known hierarchical linear modeling approach, based on 114 effect sizes from 23 studies, a meta‐analysis was conducted to examine the effects of read‐aloud accommodations for students with and without disabilities. In general, both students with disabilities and students without disabilities benefited from the read‐aloud accommodations, and the accommodation effect size for students with disabilities was significantly larger than the effect size for students without disabilities. Further, this meta‐analysis reveals important factors that influence the effects of read‐aloud accommodations. For instance, the accommodation effect was significantly stronger when the subject area was reading than when the subject area was math. The effect of read‐aloud accommodations was also significantly stronger when the test was read by human proctors than when it was read by video/audio players or computers. Finally, the implications, limitations, and directions for future research are discussed.     

Integrating multi‐tiered measurement outcomes for special education eligibility with sequential decision‐making methodology

Changes to federal guidelines for the identification of children with disabilities have supported the use of multi‐tiered models of service delivery. This study investigated the impact of measurement methodology as used across numerous tiers in determining special education eligibility. Four studies were completed using a sample of inner‐city children (N = 150) who were administered a reading screener twice and a reading measure adapted from the state high‐stakes reading test. A sub‐sample of children identified as At‐Risk were administered a comprehensive reading assessment and compared with a randomly selected control group, who were also administered a comprehensive reading assessment (n = 14). A model was developed to estimate the likelihood of special education eligibility based on both theoretical and empirical measurement parameters. Depending on the measurement assumptions of the multi‐tiered model, special education eligibility outcomes varied from a low of 0.2% to as high as 11%, depending on the type of measure used, decision‐making criteria used at each tier, and the number of tiers in the model. This study highlights the importance of measurement specification, explicit decision‐making criteria, and empirical investigation to fully understand outcomes associated with the implementation of multi‐tiered models. Implications for special education eligibility policy and practical implications for implementing comprehensive measurement practice in multi‐tiered systems at the school level are discussed. © 2012 Wiley Periodicals, Inc.     

A Tiered Intervention Model for Early Vocabulary Instruction: The Effects of Tiered Instruction for Young Students At Risk for Reading Disability

Vocabulary knowledge at school entry is a robust predictor of later reading achievement. Many children begin formal reading instruction at a significant disadvantage due to low levels of vocabulary. Until recently, relatively few research studies examined the efficacy of vocabulary interventions for children in the early primary grades (e.g., before fourth grade), and even fewer addressed vocabulary intervention for students at increased risk for reading failure. In more recent work, researchers have begun to explore ways in which to diminish the “meaningful differences” in language achievement noted among children as they enter formal schooling. This article provides a review of a particularly effective model of vocabulary intervention based on shared storybook reading and situates this model in a context of tiered intervention, an emerging model of instructional design in the field of special education. In addition, we describe a quasi‐experimental posttest‐only study that examines the feasibility and effectiveness of the model for first‐grade students. Participants were 224 first‐grade students of whom 98 were identified as at risk for reading disability based on low levels of vocabulary. Results of a multivariate analysis of variance revealed significant differences on measures of target vocabulary knowledge at the receptive and context level, suggesting that students at risk for reading failure benefit significantly from a second tier of vocabulary instruction. Implications for classroom practice as well as future research are provided.     

Teaching English Language Learners At Risk for Reading Disabilities to Read: Putting Research into Practice

The purpose of this article is to describe features of interventions that are empirically validated for use with first‐grade students at risk for reading disabilities who are English language learners (ELLs) and whose home language is Spanish. The empirical evidence supporting these interventions is summarized. Interventions for improving oral language and reading abilities with struggling readers who are ELLs taught in either Spanish or English are described as a means to assist school districts and teachers in defining and implementing effective interventions for ELLs at risk for reading difficulties. The interventions described may be useful to educators seeking information about Response to Intervention as a means of identifying ELLs who require services for learning disabilities.     

Determining Appropriate Accommodations for Postsecondary Students with Reading and Written Expression Disorders

One of the most significant barriers facing postsecondary students with reading and written expression disorders who are eligible to receive specific accommodations is the lack of professional knowledge pertaining to issues surrounding accommodations. Though guided by Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act, the process by which accommodation decisions are made varies considerably across institutions of higher education. Given the recent rise in litigation surrounding the practice of how accommodations are determined as well as the increasing number of postsecondary students with reading and writing disabilities who are requesting accommodations, it is imperative that accommodation decisions be defensible and supported by empirical research. The purpose of this article is to provide an overview of current research on the effectiveness of accommodations for postsecondary students with language‐based learning disabilities, discuss important considerations in the accommodation selection process, and offer recommendations for future research.     

Print Reading in General Education Kindergarten Classrooms: What Does It Look Like for Students At‐risk for Reading Difficulties?

The purpose of this study was to examine the amount of time spent actively engaged in reading sounds, words, and connected text for students at‐risk for reading difficulties in the first formal grade of reading instruction, kindergarten. Observational data of 109 kindergarten students at high‐risk for later reading difficulties were collected during general education reading instruction across the school year. Findings revealed students read orally for just over 1 minute during their reading instruction with approximately equal time spent reading sounds, words, or connected text. Implications of these results for early reading instruction and intervention for students at‐risk for reading difficulties or disabilities are presented.     

The Literacy Skills of English Language Learners in Canada

The purpose of this article is to review published studies of the English literacy of children in Canada who are English language learners (ELLs) with the goal of understanding the reading development of ELLs and characteristics of reading disabilities (RD) in this population. Phonological processing, syntactic awareness, and working memory of ELLs with and without RD were compared to that of native English‐speaking (L1) students with and without RD. Our review found that ELLs with RD experienced reading difficulties similar to those of L1 students with RD. On the basis of the evidence, ELLs are not at greater risk for RD than their native English‐speaking peers. We propose that the diagnosis of a reading disability can be made in a similar manner in both ELL and L1 students.     

How do general knowledge and reading strategies ability relate to reading comprehension of high school students at different educational levels?

The study examines the relationship between general knowledge, skills in applying reading strategies, and reading comprehension for ninth‐grade students at varying educational levels: academic, semi‐academic, vocational and learning disabilities. Two hundred and five students received a battery of tests evaluating their general knowledge, skills in applying four reading strategies (summary, self‐questioning, clarification and prediction), and two reading comprehension tests. The findings revealed differential contributions of general knowledge and strategy application to reading comprehension. Compared with the academic students, semi‐academics have deficient strategic skills. Vocational students, in addition to deficient strategic skills, have poor general knowledge, which further impedes their reading comprehension. The deficiency of students with learning disabilities goes beyond these two components. These results led us to recommend different foci of comprehension intervention for each group.     

Assessing college-level learning difficulties and "at riskness" for learning disabilities and ADHD: development and validation of the learning difficulties assessment

This article describes the development and validation of the Learning Difficulties Assessment (LDA), a normed and web-based survey that assesses perceived difficulties with reading, writing, spelling, mathematics, listening, concentration, memory, organizational skills, sense of control, and anxiety in college students. The LDA is designed to (a) map individual learning strengths and weaknesses, (b) provide users with a comparative sense of their academic skills, (c) integrate research in user-interface design to assist those with reading and learning challenges, and (d) identify individuals who may be at risk for learning disabilities and attention-deficit/hyperactivity disorder (ADHD) and who should thus be further assessed. Data from a large-scale 5-year study describing the instrument's validity as a screening tool for learning disabilities and ADHD are presented. This article also describes unique characteristics of the LDA including its user-interface design, normative characteristics, and use as a no-cost screening tool for identifying college students at risk for learning disorders and ADHD.     

A Meta‐Analysis of Research on the Read Aloud Accommodation

Read aloud is a testing accommodation that has been studied by many researchers, and its use on K‐12 assessments continues to be debated because of its potential to change the measured construct or unfairly increase test scores. This study is a summary of quantitative research on the read aloud accommodation. Previous studies contributed information to compute average effect sizes for students with disabilities, students without disabilities, and the difference between groups for reading and mathematics using a random effects meta‐analytic approach. Results suggest that (1) effect sizes are larger for reading than for math for both student groups, (2) the read aloud accommodation increases reading test scores for both groups, but more so for students with disabilities, and (3) mathematics scores gains due to the read aloud accommodation are small for both students with and without disabilities, on average. There was some evidence to suggest larger effects in elementary school relative to middle and high school and possible mode effects, but more studies are needed within levels of the moderator variables to conduct statistical tests.     

Accommodating differences: variations in differentiated literacy instruction in Grade 2/3 classrooms

Although teachers are acutely aware of variance in students' literacy needs, many are unsure exactly how to support these needs in the dynamic classroom. This study reports on compelling evidence from Grade 2/3 classrooms in which teachers differentiated instruction in a variety of ways to benefit all students. In particular, teachers provided additional scaffolding for struggling literacy learners by offering a menu of tiered work products, expert tutoring and additional supports. At the base of instruction were common essential understandings grounded in best literacy practices: shared reading and writing, guided reading, excellent texts and literacy centres. The article emphasises the critical importance of responding to the needs of diverse and at‐risk learners in the regular classroom. Differentiated instruction is suggested as a powerful organising framework in the language arts classroom.     

The Effectiveness of a Color‐Coded,Onset‐Rime Decoding Intervention with First‐Grade Students at Serious Risk for Reading Disabilities

This study was an investigation into the effectiveness of a color‐coded, onset‐rime–based decoding intervention with first‐graders at serious risk for reading disabilities using a single‐subject multiple probe design. Students increased their ability to decode instructional words on average 73% over baseline. For novel words from instructed rime patterns, scores increased by an average of 56%. Transfer at the vowel level to uninstructed rime patterns was limited, with scores improving by an average of 29%. Students maintained decoding gains at 1‐week and 1‐month maintenance. While acknowledging the difficulty in predicting reading disabilities based on first‐grade performance, the effectiveness of the early intervention is a promising step in finding an instructional approach that is successful with the most at risk or disabled students who often do not respond to effective remedial programs.     

Using Test Scores From Students With Disabilities in Teacher Evaluation

Much of the recent focus of educational policymakers has been on improving the measurement of teacher effectiveness. Linking student growth to teacher effects has been a large part of reform efforts. To date, neither researchers nor practitioners have arrived at a consensus on how to treat test scores from students with disabilities in growth‐based teacher effectiveness indicators, despite the fact that these students make up approximately 13% of the K‐12 student population. In this study, we leverage longitudinal data from the population of teachers in one state to explore practical questions related to including general assessment scores from students with disabilities in teacher evaluation. Findings suggest that including test scores from students with disabilities allows more teachers to be evaluated and does not substantially affect teachers’ scores. Moreover, including disability‐related covariates can allow for fairer evaluations for teachers with many students with disabilities in their class.     

Promising Practices for Providing Alternative Media to Postsecondary Students with Print Disabilities

For postsecondary students with disabilities influencing reading performance, printed class materials pose a substantial barrier and have a negative impact on academic achievement. Digital technologies offer alternative ways of accessing print materials for students with print‐related disabilities. Alternative media is a broad term that encompasses a variety of formats into which printed text is converted. Alternative media, together with assistive computer technologies designed to read aloud the text, provide a means to access textual information and bypass the difficult reading process. The purpose of this article is to provide an overview of model programs and pertinent research on the use of alternative media by postsecondary students with print disabilities; we will identify promising practices for students whose disabilities negatively influence reading performance.
