Twenty percent of all school aged children in this country have been labeled Learning Disabled. But what is a genuine learning disability and how does it differ from garden-variety poor learning? How can we more accurately assess and then teach to learning strengths instead of to weaknesses? In this passionately argued yet clear-headed book, internationally acclaimed cognitive psychologist Robert Sternberg and research scientist Elena Grigorenko tackle these controversial issues, urging that we must first understand the full range of factors that contribute to learning disabilities (and sometimes to their misdiagnosis) in order to improve the American educational and diagnostic systems.From the biological bases of dyslexia and other disabilities, to the tests that do and do not accurately assess learning abilities, to the social and educational pressures that contribute to misdiagnosis in this country, clearly outlines the issues that concern both parents and teachers, ultimately pointing to clear strategies for improving our system to help children with all manner of learning problems.
