"This book addresses a key issue in mathematics education today. The perspective from which this text is written is one that is needed as a response to the occurring reform in mathematics education and the movement to understand learning and doing mathematics as social construction. How to align this newer conceptualization with testing procedures is an issue that is often raised in the circles in which I am active. I especially like the emphasis on the use of assessment as an integral part of the learning and teaching process that is evident in several of the chapters." — Constance Smith, State University of New York at Geneseo"The book will appeal to mathematics education researchers, curriculum developers, supervisors, and personnel at state and national testing agencies. Those interested in general issues of assessment will also be interested in this book, particularly because mathematics is leading the reform of curriculum and assessment in schools in this country today." — Judith T. Sowder, San Diego State University
