Dyslexia refers to a persistent difficulty specific to word reading and spelling. Dyslexia may lead to difficulties in text reading fluency, reading comprehension, and written expression, which in turn may impact learning across curricular content areas and contribute to social-emotional challenges. This research advisory provides an overview of…

This phenomenological study explored how five participants used their Texas state-approved definition of dyslexia to identify children with dyslexia as different from those with other global reading difficulties. Drawing on theories from disability studies in education and dis/ability critical race theory, I interviewed participants who identified…

We address defining and identifying students with dyslexia within the context of multi-tier systems of support (MTSS). We review proposed definitions of dyslexia, evidence for proposed definitional attributes, and emphasize the role of response to intervention in identifying students with dyslexia. We identify dyslexia as individuals with specific…

We address defining and identifying students with dyslexia within the context of multi-tier systems of support (MTSS). We review proposed definitions of dyslexia, evidence for proposed definitional attributes, and emphasize the role of instructional response in identifying students with dyslexia.

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…

Beginning with the 2020/21 school year, the Massachusetts Department of Elementary and Secondary Education (DESE) began an ongoing effort to collect and analyze literacy screening assessment data from schools and districts participating in certain state grants to inform improvement efforts. Grantee schools and districts that provide literacy…

The Social Constructionism and New Literacies Studies supported the idea that the concept of (struggling) reader is not a given but is constructed in social interactions. With the literature review, I found that the frequently used term, "struggling reader," was ill-defined and felt the need to see how the concept is used in reading…

Some children experience more difficulty than others becoming literate, often at great emotional, intellectual, social, and economic cost to themselves, but also to those who love and care for them, and for society at large. The causes of those difficulties and what to do about them have been the source of much research and sometimes heated…

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…

Dyslexia affects about one in every five individuals, making it the most commonly diagnosed learning disability. For individuals with dyslexia, specific portions of the brain typically associated with important reading processes may not develop or function in the same ways that they do in individuals without dyslexia. Neuroimaging research…

California's school system is under tremendous long-run fiscal pressure; allocating resources efficiently is therefore paramount. Economic analysis--making sure districts and schools are spending their budgets wisely--is the method used to identify effectiveness and efficiency. This method responds to the question educational professionals face:…

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…

Today 195 countries exist in the world. The purpose of this review was to provide a global picture of the services and opportunities for individuals with dyslexia. The intent was not to provide an exhaustive review of each topic, but rather to provide examples of what is occurring in different countries around the world. Through an Internet…
