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…

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…

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,…

The purpose of this project was to examine programs and services for students with emotional/behavioural disorders (E/BD) across Canada. It is a replication of a survey undertaken a decade prior intended to examine similarities and differences in Canada's provinces and territories, as well as exploring overall changes to policy and process 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 paper attempts to illuminate a central concept and idea in special education discourse, namely, "special needs". It analyses philosophically what needs are and on what grounds they are defined as "special" or "exceptional". It also discusses whether sorting needs into ordinary and special is discriminatory. It is argued that individualistic…

School psychologists in North America are facing a transformation of their professional practices brought about by impending changes in operational definitions of learning disabilities (LD). This multimethod study explores the learning disabilities-related beliefs and practices of school psychologists in Western Australia, where these changes have…

The effects of broadening the definition of eligibility for services from the Washington State Division of Developmental Disabilities (DDD) are analyzed. Five different definitions are discussed. The existing definition includes: (1) "statutory conditions," which includes persons who are mentally retarded or have difficulty carrying out…

This paper argues that because estimates of the number of people with developmental dyslexia range from 3% to 20% of the population, it is imperative that educators be knowledgeable about dyslexia, including being up-to-date on the neuroanatomical dyslexia research. It then reviews neuroanatomical research, including findings from seminal research…

This report summarizes characteristics of students with disabilities in the National Education Longitudinal Study (NELS:88), which conducted a base-year survey in 1988 of all U.S. public and private schools containing eighth grades, followed up at 2-year intervals in 1990, 1992, and 1994. Among general observations are the following: (1) students…

This report responds to Delaware state legislation requiring the development of proposed revised regulations for the classification of students as learning disabled (LD). The report first describes the current system, noting that in 1997 15 percent of the student population were served under the Individuals with Disabilities Education Act and over…

This article describes the problem-solving model (PSM) used in the Minneapolis Public Schools to guide decisions regarding intervention in general education, special education referral, and evaluation for special education eligibility for high-incidence disabilities. Program evaluation indicates students received special education services earlier…

The process whereby children are identified as learning disabled (LD) and the validity of subsequent educational placements were evaluated. A representative sample of 1,000 students were analyzed both quantitatively and qualitatively, and extensive questionnaires were administered to LD teachers, principals, and other professionals involved in LD…
