Widely regarded as the standard reference in the field, this comprehensive handbook presents state-of-the-art knowledge about the nature and classification of learning disabilities (LD), their causes, and how individuals with these difficulties can be identified and helped to succeed. Best practices are described for supporting student performance in language arts, math, and other content areas. Contributors also identify general principles of effective instruction and review issues in service delivery within response-to-intervention (RTI) frameworks. The book critically examines the concepts and methods that guide LD research and highlights important directions for future investigation.
