The increased complexity of educational processes at times of global change calls for new research and theoretical inquiry to address how changes such as economic, social and political disruption, financial recession, international migration, and new and rapid technological advancements affect education, schools, and student learning and adjustment. Specifically for motivation in education, the fundamental assumption is that, on the one hand, change and challenge have a significant impact on students' and educators' motivation to learn and achieve and, on the other hand, motivation can have a significant impact on students' and educators' capacity to cope with change and challenge effectively. This chapter introduces the reader to the present volume in the Advances in Motivation and Achievement Series which is dedicated to the role of motivation at times of change and uncertainty.
