Drawn from the 15th International Conference on Motivation, held in Thessaloniki, Greece, in 2016, and contributed by education, psychology, and other researchers working in Europe, the US, Israel, the United Arab Emirates, and Australia, the 12 chapters in this volume examine the role of motivation in relation to the impact of global changes on education, schools, and student learning and adjustment and how to support achievement motivation in challenging times. They discuss current motivational theories at a time of global change and uncertainty, including expectancy-value theory, educational relevance, teaching motivational practices based on self-determination theory, and motivation interventions; individual and contextual factors related to motivation, namely identity, gender, parental beliefs and practices, and immigrant and refugee students; and motivation and current challenges due to global change and uncertainty, with discussion of motivation in collaborative learning, school alienation in early adolescence, and at-risk secondary students with and without a migration background.
