In response to a previous article, the paper suggests it is unrealistic to expect one theory or even multiple theories within one paradigm to explain learning disabilities. The emphasis on reaching a consensus regarding theory or paradigm is seen as unproductive. (DB)

Briefly reviews conceptual and operational limitations of classic approaches to classifying learning disabled children. Examines new classification research with learning disabled populations which is investigating alternative classification schemes through systematic and empirical hypothesis-testing paradigms, and sparking renewed interest in…

In response to a previous article, the paper discusses the distinction between basic and applied research, two contributions of applied research to theory concerning learning disabilities, and issues in metatheory development. (DB)

In response to a previous article, the paper suggests that solutions to current problems in learning disabilities are not directly dependent upon, and may not be affected by, basic research. The necessity of a coordinated theoretical foundation for research and the wisdom and feasibility of a movement to basic research are discussed. (DB)

In response to a previous article, the paper characterizes learning disabilities as the consequence of a transaction between students exhibiting certain individual differences and the social system of the schools. Basic and applied research can be related in good instructional research which includes the context of disability. (DB)

Four issues facing the field of learning disabilities are discussed: (1) defining learning disabilities in terms of discrepancy scores; (2) delineating the boundaries of how specific a learning disability must be; (3) identifying treatments with scientific credibility; and (4) implementing instructional policy that is in the best interest of the…

In response to a previous article, the paper notes additional reasons for the deficit in basic research and theory in learning disabilities, stresses the need for more good systematic research using multiple methods, and suggests that a metatheory for learning disabilities is not yet possible or profitable. (DB)

In response to a previous article, the paper stresses that, in addition to theory development, the field of learning disabilities needs to resolve definitional issues involving disability specificity, intelligence, measurement concepts, and the continua of abilities. Suggestions for developing operational definitions of both learning disabilities…

This article urges establishment of an infrastructure to promote reform in the design, adoption, selection, and implementation of high quality commercial technology, media, and materials (TMM) to benefit all students, especially students identified as learning disabled. Four "brutal" market realities suggest that the emphasis must be on quality…

The article addresses what is regarded as unjustifiably pessimistic characterizations of memory strategy instructional research, and argues that solid laboratory research on strategy use is needed though much memory instructional research with direct classroom applications to learning-disabled students has been completed. (Author/DB)

This article introduces a series of papers on cognitive process-based instruction for students with learning disabilities. Cognitive process-based instruction is defined and differentiated from the process training advocated by S. Kirk in the 1970s. The method's basis of sound theory and academic tasks is stressed. (DB)

The review describes the advance organizer technique and reviews the empirical evidence on the effectiveness of advance organizers with both normal students and students classified as handicapped. Examples of advance organizers include the expository advance organizer, the comparative advance organizer, the graphic advance organizer, and…

In response to a previous article, the paper argues that effective instruction of the learning disabled is most likely to develop from systematic theoretically based research though instructional studies can contribute to theory development. Research in many other areas is necessary to develop the powerful teaching methods required. (DB)

In response to a previous article, the paper finds weaknesses in the mechanistic worldview represented by the emphasis on information processing research in constructing a metatheory for learning disabilities. An alternative--contextualist--world view is proposed which is holistic, social, and developmental providing insight into processes of…

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…
