This paper reviews research on the classification of students with learning disability (LD). It first examines the evolution of LD definitions and the evidence for three components of LD classification: discrepancy, heterogeneity, and exclusion. It suggests that classification hypotheses involving discrepancy and exclusion have weak validity and…

This paper provides a rationale for basic research and metatheory development in the field of learning disabilities, outlines the steps and cognitive parameters involved in validating such a metatheory, and discusses integrating the findings of basic research with instructional manipulations and reasons for the poor integration of theory and…

This paper affirms H. Lee Swanson's views in "Toward a Metatheroy of Learning Disabilities" and elaborates upon the role of basic research in learning disabilities. An alternative perspective on the nature of applied research is described that views applied research as theoretically driven research aimed at practical matters. (JDD)

In response to H. Lee Swanson's paper, "Toward a Metatheory of Learning Disabilities," this article argues that the field of learning disabilities does not need to be legitimized and that basic research in learning disabilities is not necessarily the prerequisite vehicle by which theoretical progress can be made. (JDD)

This article synthesizes articles discussed as part of the research symposium at the 24th International Conference on Learning Disabilities on October 11, 2002. Topics include translating learning disability research to practice, identification of learning disabilities, special education and postmodernism, and the response to treatment model.…

This article examines what science offers general and special educators who teach reading. It reviews scientific findings about reading and their practical implications and considers some broader ways that science may be useful to educators. Suggestions for educators interested in becoming more astute consumers of research are provided. (Contains…

In response to H. Lee Swanson's paper, "Toward a Metatheory of Learning Disabilities," this counterpoint addresses the role of basic versus applied research, limitations of the procedure proposed by Swanson for establishing external validity and proving the metatheory, and limitations of metatheoretical research with regard to developing…

In rebuttal to H. Lee Swanson's paper, "Toward a Metatheory of Learning Disabilities," this article emphasizes that a bias toward applied research in learning disabilities is appropriate, that explanatory theories may not provide control over the phenomena explained, and that the field's orientation toward social consensus rather than…

This response to H. Lee Swanson's paper, "Toward a Metatheory of Learning Disabilities," argues that the field's development from social consensus has positive consequences and that the field is a "prenormal' science. A megatheory is suggested, incorporating metatheoretical aspects of the learning-disabled's information processing…

This article synthesizes key findings to facilitate the translation of research into classroom practice and provides guidelines for how effective instructional practices might be implemented, supported, and sustained in schools. Excerpts from a case study are presented to show how research-based instructional approaches translate into classroom…

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…

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…

Reactions to H. Lee Swanson's paper "Toward a Metatheory of Learning Disabilities" are outlined, and his arguments are applied to reading disabilities, focusing on the importance of the scientific attitude, the misuse of ecological validity, interpretation of Thomas Kuhn's work, modularity and reading disability, and scientific progress…

This critique of H. Lee Swanson's "Toward a Metatheory of Learning Disabilities" comments on Swanson's concept of learning disabilities, cognitive science, and information processing theory. A different research and theory-building agenda is proposed, focusing on society's definition of learning disabilities and instructional issues and…

This article analyzes factors related to bringing research-validated practices to scale to enable implementation of responsiveness-to- intervention models in special education. Key components of effective literacy programs are discussed, along with findings from reading intervention research. The need for professional collaboration among…
