This article proposes use of a life-span developmental perspective in research on adults with learning disabilities. Considerations for incorporating such essential concepts as mediating variables, context, and age-span phases into research on this population are discussed. (DB)

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…

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…

This article examines the research surrounding definitions and selection criteria for learning disabilities and attention deficit/hyperactivity disorder at the postsecondary level. Implications from and for the courts follow a critical analysis of the professional literature. The need for theory-based models to investigate relationships between…

This article reviews Bakker's developmental neuropsychological model (the Balance Model) of reading development (EC 602 750), notes the need for validating research before employing these procedures in clinical practice, and raises some conceptual problems such as evidence that learning disability subtypes evolve over time.

This article uses a sociocultural perspective of teaching and learning to synthesize previous articles in the series and speculate on future inquiry in the field of learning disabilities. It provides a model showing the expanding sociocultural contexts that frame learning and teaching. (DB)
