This book is a collection of papers presented at the symposium, "Conference on Ordinal Scales of Cognitive Development", sponsored by the California Test Bureau.

Inhelder in her introduction. The reason for this unity is that explanatory adequacy can be attained only by exploring the formative and constructive aspects of development. To explain a psychologic reaction or a cognitive mechanism (at all levels, including that of scientific thought) is not simply to describe them, but to comprehend the processes by which they were formed; failing that, one can but note results without grasping their meaning. JEAN PlACET VI Man distinguishes himself from other creatures primarily by his abstract reasoning capacity and his ability to communicate his knowledge by highly complex symbolic processes. What is called "humanity" and progress is to a large degree a measure of his consciousness and the deployment of his creative potentials. There are few scientists who have explored the universe of cogni tion, and contributed to the understanding of the realm of knowledge, with greater genius, care, and scientific intuition than Jean Piaget and his longtime collaborator Barbel Inhelder. Professor Inhelder and her assistant Dr. Harold Chipman realized this book in spite of the heavy load of research, teaching, and administra tive duties in a rapidly expanding Institute. It is therefore a particular pleasure for me to presen t this book.

Piaget helps us to see the developmental significance of a child's failures and successes in thought and action during everyday experience by breaking down each activity into its separate mental elements. We have to tried to draw the educational implications from the developmental facts thus revealed. In recent years teachers have had to learn a great deal about mental measurement as this has become an important feature in our educational structure. This has led to much emphasis on the quantitative assessment of intellectual ability, since in most intelligence tests the main concern is with the number of right responses. In his 'open-ended tests' Piaget seeks to find in a large number of situations what it is that we take for granted which the children have not grasped. To do this he examines the processes of thought and the degree of success and failure, which should be of much greater diagnostic value to the practising teacher. It also gives further support to those who believe in the need for an individual approach to each child's learning. For many years, people who have worked in child centred education have had philosophical theory and intuitive judgment to guide them, but have lacked scientific justification for what they were doing. Piaget's work is now providing scientific evidence from experiments, with concrete examples and demonstration from children's behaviour for what was previously a matter of opinion. We have chosen the examples to cover a wide age range partly to emphasise the genetic approach and partly to appeal to as wide an audience of teachers as possible. In addition we tried to choose pieces that held special promise of applicability in schools.

This volume marks the 20th Anniversary Symposium of the Jean Piaget Society. Some of the American contributors were among the first to introduce Piaget to developmental and educational psychology in the United States, while some of the international contributors worked with Piaget to develop his program of genetic epistemology and continue to make significant contributions to it. Within this volume the possibility of Piaget's paradigm is reviewed not only as the stuff of normal science, yielding fascinating empirical questions that linger within it, but also, and more importantly, as the stuff of revolutionary science, with continuing potential to comprehensively structure our thinking about developmental theory. The constructive contribution Piaget's theory has for developmental theory emerges as four central themes in the volume: understanding the intentional or semantic aspect of mental life without abandoning the Piagetian assumption that is rational and committed to truth testing; examining mental life and its development as a dialectical relation of function and structure--a relation Piaget introduced in his study of the developmental relation between procedural and operational knowledge; exploring new and interdisciplinary perspectives on equilibration as the driving force of constructive adaptive processes; understanding social and historical forces in individual and cultural development--not necessarily as forces antithetical to Piaget's perspective but as forces that take on new meaning within his framework which avoids erroneous dichotomies such as the distinction between subjective and objective knowledge.

This collection of original contributions by leading researchers celebrates the 1996 centenary of the births of the two most seminal figures in education and developmental psychology - Jean Piaget and Lev Vygotsky. Research in their footsteps continues worldwide and is growing. What are the implications for the future for this extensive programme? Which of the large body of findings has proved most important to current research? Based around five themes, these original contributions cover educational intervention and teaching, social collaboration and learning, cognitive skills and domains, the measurement of development and the development of modal understanding.

What is meant by the term "intelligence" and, once de-fined, how do we go about achieving a valid measurement of this faculty? This classic textbook, originally published in 1979, and now reissued with a new preface by Sybil Eysenck, incorporates a broad range of findings and reanalyzes much of the existing literature in this area.In The Structure and Measurement of Intelligence, Hans Eysenck draws on methods for determining the effect of genetics and environment on the development of intelligence and examines the validity of the term as defined in relation to internal as well as external criteria. He tests a number of hypotheses on intelligence against empirical research findings and considers various criticisms in detail. The significance of intelligence and its measurement in society are explored in depth. Eysenck greatly expands upon such questions as: Does IQ measure intelligence? How valid is the nature versus nurture argument? and, How might socioeconomic status influence one's intelligence? Designed primarily for students and scholars in psychology and education, this text will make thought-provoking reading for all concerned with the development and measurement of intelligence in the individual. Hans J. Eysenck (1916-1997) was professor of psychology at the University of London and the director of its psychological department at the Institute of Psychiatry. He was best known for his experimental researches in the field of personality. Among his many books are Rebel with a Cause, Dimensions of Personality, The Dynamics of Anxiety and Hysteria, Intelligence, and Decline and Fall of the Freudian Empire, all available from Transaction. Sybil B. G. Eysenck, wife of the late author, is co-director of Personality Investigations, Publications and Services (PIPS), an organization devoted to the promotion of the writings and research of Hans J. Eysenck. She is the co-author, with Hans Eysenck, of Psychoticism as a Dimension of Personality and Personality Structure and Measurement and the co-editor, with Donald Saklofske, of Individual Differences in Children and Adolescents, published by Transaction.

This book, the last one written by Piaget, presents a new line of empirical studies based on a revised formulation of his theory of the development of logical reasoning. The amended theory overcomes many problems and criticisms of his earlier formulations by providing a fresh explanation for the origin of mental operations and mental organization based on the concept of meaning. It also offers a more elegant vision of the continuity in mental development from birth to adulthood. As the final revision of Piaget's theory -- and one that opens up new areas of inquiry -- this book calls for a reinterpretation of his earlier work -- a task which will occupy scholars for decades to come.

"From applied behavior analysis to vicarious reinforcement, overviews of theories outline concepts basic to the field of educational psychology. Each of the 275 scholarly articles give sample suggestions for further research. All told, the set provides a useful introduction to a bourgeoning area of study and is highly recommended for academic libraries." —John R. M. Lawrence "This comprehensive, informative, cross-disciplinary, and authoritative encyclopedia supports a holistic approach to preschool to adult education and would make a welcome addition to any undergraduate collection." —Library Journal Educational Psychology is a special field of endeavor since it strives to apply what we know about many different disciplines to the broad process of education. In the most general terms, you can expect to find topics in this area that fall into the categories of human learning and development (across the life span), motivation, measurement and statistics, and curriculum and teaching. There are few comprehensive overviews of the field of educational psychology, and the purpose of this two-volume Encyclopedia is to share this information in a way that is, above all, informative without being overly technical or intimidating. With more than 275 contributions, the Encyclopedia of Educational Psychology opens up the broad discipline of educational psychology to a wide and general audience. Written by experts in each area, the entries in this far-reaching resource provide an overview and an explanation of the major topics in the field of human development. While the Encyclopedia includes some technical topics related to educational psychology, for the most part, it focuses on those topics that evoke the interest of the everyday reader. Key Features Addresses topics that are of particular interest to the general public such as vouchers, Head Start, divorce, learning communities and charter schools Shares subjects that are rich, diverse, and deserving of closer inspection with an educated reader who may be uninformed about educational psychology Draws from a variety of disciplines including psychology, anthropology, education, sociology, public health, school psychology, counseling, history, and philosophy Presents many different topics all tied together by the theme of how the individual can best function in an educational setting, from pre-school through adult education Key Themes Classroom Achievement Classroom Management Cognitive Development Ethnicity, Race, and Culture Families Gender and Gender Development Health and Well-Being Human Development Intelligence and Intellectual Development Language Development Learning and Memory Organizations Peers and Peer Influences Public Policy Research Methods and Statistics Social Development Teaching Testing, Measurement, and Evaluation Theory This practical Encyclopedia brings the field of educational psychology to the everyday person making it a welcome addition to any academic or public library.
