The author suggests that, if the purpose of classification is to provide educational services, the category of learning disabilities be used to describe pupils with mild handicaps. She cites the folly of research on sytem-selected students because system-selection decisions are biased by political, practical, and financial influences. (CL)

Critically evaluates recent research aimed at empirical identification of homogeneous subtypes of learning disability. It is suggested that researchers strive for more commonality in the methods and measures used for subtype analysis leading to a single classification scheme to reduce heterogeneity and improve educational efforts.

The paper reviews the recent research bearing on the single cause/multiple cause controversy in regard to reading disabilities. The inadequacy of the common practice of comparing a group of disabled readers with a control group is noted. (Author/SW)

In agreement with Coles (EC 220 146), the article comments on the poor quality of research in the learning disability field, and Coles'"interactivity" theory as an alternative to the neurological-deficit theory which is applied to the problem of classification, intervention, and a societal approach.

For successful classification of children with attention deficit-hyperactivity disorder, major issues include (1) the need for explicit studies of identification criteria; (2) the need for systematic sampling strategies; (3) development of hypothetical classifications; and (4) systematic assessment of reliability and validity of hypothetical…

Reviews the methods, technologies, and operating tenets of case studies of reading disabilities completed during the late 19th and early 20th centuries. Results suggest that the assumptions of anatomical and functional modularity for cortical processes become guiding principles for diagnosing and correcting reading difficulties. (Author/CR)
