This study examined intervention fidelity (IF) and the extent to which this essential feature of response to intervention (RtI) was included within artifacts (laws and guidance documents) for states requiring RtI for specific learning disability (SLD) identification. Intervention fidelity is defined as the degree to which an intervention is…

Background: Previous research indicated a high prevalence of disordered sleep among adults with learning disabilities, however issues with design impacted findings. The current systematic review aims to: (1) present how disordered sleep and sleep disorders amongst adults with learning disabilities are described in the literature, and (2) report on…

We use critical qualitative methods to demonstrate how ambiguities present in definitions of learning disability (LD) and processes for determining LD eligibility under IDEA result in inequitable outcomes for minoritized students. To investigate this issue, we first outline how the LD label is situated within medical and psychological…

The concept of twice-exceptional is used to define individuals who are gifted or talented in one or more domains while having disability, disorder or difficulty in certain areas. This situation has made the definition and acceptance of the concept difficult since giftedness and disability are mentioned together. In order to clarify current…

Learning disabilities are the most common eligibility category in which children qualify for special education services. Despite this, there is surprisingly little current information on the prevalence and needs of children with math disabilities, and even less information on interventions to support children in schools. This dissertation aimed to…

Background: Here, I examine the status of 'learning disability' as a basic concept. This kind of questioning may be thought a task for philosophy, or at least for 'theory' or 'disability studies'. Materials and methods: I identify history instead as a discipline well placed to reveal the category errors that surround the concept. Results: These…

In the US, undeniable evidence shows that socioeconomic inequities explain a high proportion of individual differences in school achievement. Although not all countries show this same effect due to socioeconomic status, it is consistently found that social inequities lead to achievement gaps. These achievement gaps then manifest into trajectories…

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…

This article addresses the nature of dyslexia and best practices for identification and treatment within the context of multitier systems of support (MTSS). We initially review proposed definitions of dyslexia to identify key commonalities and differences in proposed attributes. We then review empirical evidence for proposed definitional…

This paper addresses the nature of dyslexia and best practices for identification and treatment within the context of multi-tier systems of support (MTSS). We initially review proposed definitions of dyslexia to identify key commonalities and differences in proposed attributes. We then review empirical evidence for proposed definitional…

Over the past decade, there has been a rapidly declining trend in the prevalence of students with learning disabilities in South Korea. In 2019, only 1.5% of students receiving special education support were identified as having learning disabilities. This column reports on three current issues related to learning disabilities to provide a greater…

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…

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…
