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…

The author argues that despite the vast proliferation of scientific research, our understanding of dyslexia is marked by serious weaknesses of conceptualization, definition, and operationalization that are not only unscientific but also result in impoverished practice in schools, social inequity in both understanding and provision for many…

In 2016, the US Preventive Services Task Force concluded that there was "insufficient" ("I" statement) evidence to support universal primary care screening for autism spectrum disorder. The statement led to controversy among research and clinical communities. Although a number of papers have since been published arguing for the…

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. We identify dyslexia as individuals with specific…

Ensuring the provision of a free, appropriate public education (FAPE) to students qualified for services under the disability category of emotional disturbance (ED) has been both challenging and controversial. Examining this population in light of the five characteristics listed in the federal definition may provide useful insights to address…

Introduction: This study examined the interstate variability in eligibility criteria for the disability category of deafblindness. Methods: We systematically reviewed and coded information related to the location of state data, the use of federal language in state definitions, additional eligibility criteria (i.e., disability eligibility…

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…

Attention-Deficit/Hyperactivity Disorder (ADHD) includes a multitude of symptoms and can be difficult to diagnose due to a variety of international definitions. Research identifies different viewpoints on diagnosis and treatment including medical, psychological, and sociocultural views. Some research suggests ADHD is a social construct and is…

This chapter is structured for teaching young learners with physical (orthopedic) disabilities in special education. Orthopedic impairments encompass a range of disabling conditions. Orthopedic impairments are typically grouped into three main categories: (1) congenital anomalies (CA) such as absence of a member or clubfoot, (2) impairments caused…

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…

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…

This chapter examines how studies focused on the same topic--disproportionality in special education--can generate vastly different conclusions about its sources and causes. By analyzing existing disagreements in the field, we explore essential questions about what constitutes high-quality and relevant evidence when seeking to understand how,…

Cerebral or cortical visual impairment (CVI) is not the unknown condition it was 50 years ago. Although research had been conducted and papers published, it was not until the 1980s that it really became an issue of concern and much debate for educators. This interest was primarily sparked by the increasing numbers of children who had been…
