The terms interactive and dynamic would never have been associated with psychological and psychoeducational assessment a generation ago. They have currency now because of widespread dissatisfaction with the normative, standardized testing model, criticism of theoretical concepts of intelligence, recognition of abuses of standardized intelligence testing, and frustration with prediction and classification as primary goals of assessment. It is almost certainly true that public policy concerns propel scientific activity far more often than science propels public policy In the case of psychological assessment, public policy concerns have arisen in the last 20 years primarily around issues of possible "discrimination" against members of ethnic minorities. At the same time, there has been a re surgence of dedication to "excellence in education" goals. These concerns have led to such extreme measures as prohibition of the use of standard ized intelligence tests to determine school placement decisions, especially for minority children. They have led also to a search for alternatives to standardized, normative testing. The chapters in this volume represent a variety of answers to this need."

This book portrays an extensive and intensive discussion of theories and research that refer to Vygotsky's and Feuerstein's theories of mediated learning and their effects on learning potential and cognitive modifiability. Most topics are discussed in relation to a broad spectrum of developmental and cognitive research that are under the conceptual umbrella of mediated learning and cognitive modifiability. Some topics such as neural plasticity, executive functions, mental rotation, and cognitive education are related to mediated learning, though indirectly, and therefore are included in this book. In many ways the book presents an extension of Vygotsky and Feuerstein's theories and empirical validation in a variety of family, social and cultural contexts. The book includes a thorough analysis and summary of 50 years of research and methodology of the intimate relation between mediated learning interactions and cognitive modifiability and of dynamic assessment underlying measurement of cognitive modifiability. Special emphasis is given to Tzuriel's dynamic assessment instruments developed during more than four decades. Tzuriel's novel instruments are interwoven in the extensive research on parent-child interactions, siblings' , teachers' and peers' mediation and in validation of dynamic assessment approach and cognitive education programs aimed at development of thinking skills and academic achievements.

The past two decades have witnessed a proliferation of research dealing with dynamic-interactive assessment as an alternative to conventional psychometric measures. This book establishes dynamic assessment as a useful approach that complements standardized normative tests in portraying an accurate picture of cognitive functioning and offering a more adequate assessment of handicapped persons and persons with learning disabilities.
