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…

Dyslexia is a difficulty in learning to decode (read aloud) and to spell. DSM5 classifies dyslexia as one form of neurodevelopmental disorder. Neurodevelopmental disorders are heritable, life-long conditions with early onset. For many years, research on dyslexia proceeded on the basis that it was a specific learning difficulty -- specific meaning…

This research synthesizes studies that used a Digitalized Interactive Component (DIC) to assess K-12 student mathematics performance during Computer-based-Assessments (CBAs) in mathematics. A systematic search identified ten studies that categorized existing DICs according to the tools that provided language assistance to students and tools that…

Recently, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) reported that although countries around the world must ensure that students with disabilities receive free, inclusive, and appropriate education, students with disabilities are less likely to complete primary or secondary school in many countries. Though this…

We review the evolution of the conceptualisation of dyslexia and along with it the current, 21st century definition of dyslexia. Our starting point is the seminal report by Pringle Morgan in 1896, followed by early 20th century reports by Hinshelwood, and continuing with concepts of brain injury and minimal brain dysfunctions then to the emergence…

This article describes the efforts of a U.S. History teacher to directly teach word meanings using the "robust vocabulary instruction" (RVI) approach, because research supports this method as a way to improve vocabulary knowledge for a range of students, including adolescents reading below grade level (i.e., struggling readers) and…

Knowing the meaning of academic vocabulary words helps adolescents understand content-area text and improves their academic achievement. To demonstrate deep understanding of words, students reading below grade level and students with learning disabilities must be explicitly taught word meanings, encounter target words in illustrative contexts, and…

This is the first of two papers that explore a role that occupational therapy can play in supporting children with reading challenges. Part I presents the grounding framework for an occupation and participation approach to reading intervention (OPARI) and serves to introduce the clinical application of the approach presented in Part II. In this…

The idea of this book arose out of an awareness that students with language learning disabilities are completely ignored in the Egyptian school system and there are no special programs that cater to these students. They are placed in normal schools that are not prepared to deal with their unique difficulties. This book, therefore, is an attempt to…

Experts have yet to reach consensus about what a learning disability is, how to determine if a child has one, and what to do about it. Leading researcher and clinician Deborah Waber offers an alternative to the prevailing view of learning disability as a problem contained within the child. Instead, she shows how learning difficulties are best…

A study of articles appearing in the "Journal of Learning Disabilities," from 1971 through 1980, yielded results such as 87 percent of definitions of dyslexia were in terms of a selective reading or spelling deficiency on a standardized test and only one of 45 studies classified dyslexics.

This paper discusses the current confusion in differentiating between reading disabilities and learning disabilities, as well as the role of the learning and reading specialist. The origin and history of the movement toward helping children labeled as having a reading or learning handicap are examined, and various definitions are discussed. It is…

This article presents an operational, inclusionary definition of dyslexia constructed by the Orton Dyslexia Society Research Committee and others. Each clause of the definition is explained in terms of relevant research findings. The definition attempts to identify unique factors of reading disability, independent of its common association with…

A look at the theories of reading and corresponding attributes of a learning disability suggests that there is not actually a difference between a learning disability and a reading disability. (Author)

Recounts a reading teacher's illuminating experience with a first grader who enjoyed reading Bill Martin's "Brown Bear" books, despite being labeled as dyslexic. Dyslexia is an elusive condition that is biological in origin and distinct from other reading problems. New research shows that reading difficulties, including dyslexia, occur as part of…
