Decades of research and billions of dollars have been spent to develop and evaluate evidence-based interventions and develop multitiered systems of support (MTSS) toward the goal of more effectively delivering interventions and improving student outcomes. Available evidence, however, suggests interventions are often adopted slowly and delivered…

This article discusses six theoretical frameworks of disability which dominate studies of dyslexia: (1) the biomedical, (2) the biopsychosocial, (3) the social model, (4) the critical realist, (5) the post-structuralistic, and (6) the neurodivergent approach. The aim of this paper is to demonstrate how models of disability alter our understandings…

This article is the second part of a two-part article focusing on research that has been conducted on Content Enhancement Routines, instructional routines developed to be used during inclusive subject-area instruction. Part I of this article (Schumaker and Fisher, 2021) reviews the original validation studies that were conducted on four Content…

The National Joint Committee on Learning Disabilities (NJCLD) affirms that the construct of learning disabilities represents a valid, unique, and heterogeneous group of disorders, and that recognition of this construct is essential for sound policy and practice. An extensive body of scientific research on learning disabilities continues to support…

RTI has the potential to meet the challenges of increasing diversity in student populations and the need for increasingly complex systems of instructional design. Three fundamental shifts in understanding systems and systems change must ground RTI policy and implementation work. First, RTI must be seen as an activity system nested within a larger…

The changing job market requires a sophisticated array of literacy skills that adolescents with learning disabilities reading below grade level have not yet acquired. This summary of the research on reading comprehension highlights emerging findings and related instructional conditions necessary to achieve optimal student outcomes with limited…

We are entering a new phase in learning about childhood disabilities. While we have found out much of what we need to know about their causes and aetiology, solutions to many of the challenges we will face in the future will come from the evidence base held by practitioners. Practitioners are ideally placed to carry out "real world" research but…

The article describes the eligibility model developed by the community college system of California for students with learning disabilities. Major activities of the research and development process leading to the eligibility model are detailed including components, procedures, and criteria. The process combines clinical and databased evidence with…

Examines previous hypotheses of the causes of dyslexia. Proposes that dyslexia results from a subtle language deficiency rather than from defects in the visual system. Discusses current theories and assesses instructional strategies for dyslexics. (ML)

This article describes "Solve It!," a research-based instructional program for middle school students who have difficulty with mathematical word problems. It describes the theoretical framework of the program, reviews research on the program, presents an overview of the program, and discusses implementation issues such as finding time for…

This article presents the strategies instruction model as an effective intervention for students with learning disabilities. It describes the model's components (curriculum, instruction, environment), its theoretical basis, the teacher's role, teacher-student interaction, and appropriate contexts. Studies of the model's effectiveness are…

Special education research has undergone one of the most significant developments in the history of education during the past two decades (Gersten, Vaughn, Deshler, & Schiller, 1997). These developments can be related to the Individuals with Disabilities Education Act of 1997 and the resulting knowledge about teaching individuals with…

The Interagency Committee on Learning Disabilities, which submitted its report to Congress in August 1987, recommended a revision in the legislative definition of learning disabilities. It also recommended funding interdisciplinary research centers "to devise broad and longitudinal multidisciplinary approaches" and a central…

This article describes a multistep method for identifying effective teacher-developed instructional procedures and translating them for wide-scale use. The method employs both objective and naturalistic assessments of academic gain and engagement and was used to identify effective practices of teachers of 59 fourth- and fifth-grade students with…
