Disability can affect adults across the life span-and it is the one minority group every person could join. This sourcebook aims to broaden the view of disability from a medical or economic concern to a social justice concern. It examines practical, theoretical, and research aspects of disability-including those who question disability classifications-and situates it as a political and social justice concern, technical and pragmatic concern, and personal experience. The authors present the perspectives of individuals with disabilities, service providers, parents, and teachers and offer analyses that range from the personal to the broadly political. This is the 132nd volume of the Jossey-Bass higher education quarterly report series New Directions for Adult and Continuing Education. Noted for its depth of coverage, this indispensable series explores issues of common interest to instructors, administrators, counselors, and policymakers in a broad range of adult and continuing education settings.
