This unique volume reflects a global perspective on the nature and nurture of human motivation and will be of special interest to scholars concerned with motivation research. It also speaks directly and usefully to the practical challenge of motivating others in many different contexts, and so will be of great interest and value to all who are called upon to lead, direct, and enhance the actions of others (teachers, parents, employers, coaches,...) - which, incidentally, includes most of us at one time or another. Martin Maehr, PhD, Professor of Education and Psychology, University of Michigan In this important book, an international crew of experts provides a wealth of up-to-the-minute information for all those interested in motivation. The book advances our understanding in two main ways: First, by stimulating us to consider global versus contextualized aspects and approaches. And secondly, by highlighting the interrelatedness of motivation with other factors that influence learning and instruction, such as affect, emotions and self-regulation. The book is an indispensable source of inspiration for motivation research. Erik De Corte, Center for Instructional Psychology and Technology, University of Leuven
