The first comprehensive quantitative analysis of intervention research in the learning disabilities field, this volume synthesizes the results of 272 scientifically credible group and single-subject studies in an effort to identify what works best for learning disabled children. The book examines pertinent findings on all academic, cognitive, and behavioral domains. Intervention outcomes are evaluated across instructional domains, sample characteristics, intervention parameters, methodological procedures, and article characteristics. Addressing such questions as the merits of inclusion settings and the relative benefits of direct and strategy instruction, Swanson offers timely recommendations for instructional design, assessment, and policy.
