Despite decades of research, it has been difficult to achieve consensus on a definition of common learning disabilities such as dyslexia. This lack of consensus represents a fundamental problem for the field. Our approach to addressing this issue is to use model-based meta-analyses and Bayesian models with informative priors to combine the results…

Aims: Studies on literacy difficulties have mainly focused on children or adults who have a diagnosis of dyslexia. Some students enter university without such a diagnosis, but with literacy difficulties, and this may impact their ability to become independent learners and achieve academically. This exploratory study aims to employ a hybrid model…

Although the instructional strategy described in this article can be used to support all learners, the purpose of this article is to address the needs of students with learning disabilities, who are often several grade levels behind in reading comprehension. Specifically, this article explores how an explicitly taught instructional practice that…

This revised edition updates and expands on the first edition published in 2016. In this revised edition, theories of different types of learning strategies are expanded and more recent studies are added. A large amount of tabular information is also reconstructed in a more meaningful manner. The book is divided into five chapters. Chapter one…

As implementation of multi-tiered systems of support becomes common practice across the nation, practitioners continue to need strategies for intensifying interventions and supports for the subset of students who fail to make adequate progress despite strong programs at Tiers 1 and 2. Experts recommend making several changes to the structure and…

The purpose of this article is to provide the reader with insight into the clinical reasoning process involved in the assessment and intervention planning for a child with a reading disability. A Cattell-Horn-Carroll (CHC) theoretical/neuropsychological approach shall serve as the foundational theoretical framework for this case study, and…

School psychologists' training provides a variety of skills from which its practitioners may draw, including consultation, intervention, counseling, staff development, and assessment. Despite these broad skills, school psychologists' primary roles involve assessment and assessment-related tasks, generally as related to eligibility determination…

The present study employed data simulation techniques to investigate the 1-year stability of alternative classification schemes for identifying children with reading disabilities. Classification schemes investigated include low performance, unexpected low performance, dual-discrepancy, and a rudimentary form of constellation model of reading…

Rapid automatized naming (RAN) is widely used to identify reading disabilities (RD) and has recently been considered a potential predictor of risk for mathematics learning disabilities (MLD). Here we longitudinally examine RAN performance from Grades K to 8, to view how growth on RAN response time differs for children with RD versus MLD. Across…

Response-to-intervention (RTI) models incorporate a screening process to identify students who appear to be at risk for learning disabilities (LDs). The purpose of this position article is to incorporate what is known about screening into a flexible, yet comprehensive screening system to help school psychologists and other school administrators in…

The Individuals With Disabilities Education Act (IDEA) of 2004 encourages schools to use interventions to ensure that students' literacy difficulties are not instructional problems before assuming a learning disability. The law frames these interventions in two ways: as a strategy for identifying students with learning disabilities--a measurement…

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…

Multisensory Structured Language Instruction has been used for decades by clinicians and practitioners as an intervention for teaching students with dyslexia. Multisensory Structured Language Instruction uses the integration of multiple senses (visual, auditory, and kinesthetic/tactile) simultaneously to teach literacy. Although the anecdotal…

The purpose of this article is to describe research-based reading intervention within a Response-to-Intervention (RTI) model, using prevention science as a context. First, RTI is defined and a rationale is provided for its use in improving the reading performance of all students, particularly those students identified as at risk for…

The authors sought to (a) identify interventions that immediately increased the oral reading fluency of students with or at risk for disabilities, (b) estimate to what extent these gains maintained over time, and (c) evaluate whether particular characteristics of students (e.g., gender, disability status) predicted their response to fluency…
