Research articles (n=174) published in the "Journal of Learning Disabilities" from 1989 through 1993 were analyzed and coded by type of research design and statistical technique used. Eighty percent of the research designs were nonintervention methods; 55% of all statistical techniques were coded as primary, 32% were intermediate, and…

Discussion of conceptual and methodological aspects of reading intervention research focuses on nine specific design limitations of previous intervention research; ways to measure and analyze change as a function of development, treatment intervention and ecological influences; assumptions of individual growth models; and advantages, conditions,…

Examination of methodological issues in the design and interpretation of studies on the genetics of reading disability suggests three tests of increasing rigor for determining whether reading score distributions are categorical and thus not subject to analyses which assume a continuous normal distribution. Also noted are interactive relationships…

The importance and relevance of longitudinal research in learning disabilities is addressed, including its value in verification of appropriate hypotheses concerning particular developmental patterns and debunking of misconceptions. Examples from various longitudinal studies are given. (DB)

The author replies to responses to her article, "The Newtonian Mechanistic Paradigm, Special Education, and Contours of Alternatives" (EC 220 916). Topics covered include the degree of objectivity versus the idea of objectivity, theory-data separation versus theory-laden data, Piagetian theory and the question of theory versus paradigm,…

The paper deals with the contribution of empirical psychology to the problems of instruction and proposes a conceptual framework to promote helpful interactions between experimenters and teachers of children with learning difficulties. Both groups share a common concern, the definition of tasks by testing instructions in action. (Author/DB)

Synthesizes information from a 1995 international symposium on longitudinal research in learning disabilities. Discussion of generic considerations of longitudinal research is followed by examination of issues specific to learning disabilities including definition, attrition, composition of research teams, ethical concerns, data collection, and…

Issues are raised about the Council for Learning Disabilities Research Committee's standards for describing research subjects, including justification for the recommended standards, relationship between description of subjects and probability of replication, and impact of the type of research on subject description standards. Recommendations are…

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…
