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…

After a multitude of studies across more than a century, researchers have failed to consistently identify characteristics or patterns that distinguish dyslexia from other decoding challenges. Many researchers and educators argue the construct is too vague and contradictory to be useful for educators. Nevertheless, attention to dyslexia in policy…

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…

This is a personal story of a twice-exceptional high school student.

In this study, researchers evaluated the effects of peer-assisted multimedia vocabulary instruction, which was designed to address the goal of building knowledge of discipline-specific definitions of language arts terminology for six ninth-grade English Language Learners (ELLs) with or at-risk for learning disabilities. To evaluate the effects of…

The purpose of this study was to examine whether English language learners (ELLs) would increase their vocabulary scores in the areas of word recognition, word meaning, and word application when iPads were used during vocabulary instruction. Five third-grade ELLs, at risk of being diagnosed as having learning disabilities, participated in the…

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 purpose of the White Paper is to provide additional information for and guidance to the federal government, professional organizations, practitioners, and the public. The Learning Disabilities Association of America (LDA) is hopeful that this document will facilitate legal, regulatory, policy, and training decisions, and ultimately, service…

This study examined and compared patterns of errors in the oral definitions of newly learned words. Fifteen 9- to 11-year-old children with language learning disability (LLD) and 15 typically developing age-matched peers inferred the meanings of 20 nonsense words from four novel reading passages. After reading, children provided oral definitions…

We provided a multicomponent academic vocabulary intervention to six English learners with learning difficulties in a fifth-grade general education setting. A multiple probe design across word sets and replicated across students evaluated the effects of the intervention on students' use of expressive language to read and define content-specific…

Learning disabilities (LDs) are associated with underachievement in one or more areas such as reading, spelling, writing and/or mathematics. In general, it is assumed that LDs are neurological in origin, permanent in nature and resistant to intervention. Moreover, LDs are not considered the result of intellectual, physical or sensory disabilities,…

What is mathematical learning disability (MLD)? The reviews in this special issue adopt different approaches to defining the construct of MLD. Collectively, they demonstrate the current status of efforts to establish a consensus definition and the challenges faced in this endeavor. In this commentary, we reflect upon the proposed pathways to…

In the fourth session of the National Research Center on Learning Disabilities Responsiveness-to-Intervention Symposium in 2003, Good, Vellutino, and Torgesen presented papers that addressed the question, "How should unresponsiveness to secondary intervention be operationalized in an RTI approach to LD identification?" In this commentary, I…

Replies to criticism of work at Minnesota Institute for learning disabilities. Suggests that the work (what is known) in LD reflects the state of practice (what is done). Suggests the LD population is not clearly defined, and research does not indicate that LD children require interventions unique to their category. (Author/CL)

This article discusses issues of classification and identification, while evaluating some of the continuing controversies about learning disabilities (LD) related to those topics. The author suggests that many problems have to do with confusion between the two. Despite years of effort and an extraordinary increase in the number of individuals…
