This is a volume on problems and new solutions in the field of intercultural learning and development. Although it seems to be intuitively quite clear what is meant by "intercultural learning and development," it quickly becomes vague and hard to grasp. Many isolated and diverse studies have been conducted, but demonstrate only minor effectiveness. A more promising framework, based on socio-cultural and historical activity theory and mindful identity negotiation, is presented here. It is tested for intervention purposes and empirically evaluated by means of a design experiment. This volume is addressed to professors, students, and professional practitioners, whether working in educational research or in practical course design and implementation in different fields, such as general education, business studies, management training, workplace learning, or in studies on diversity and modern language teaching. Contents: Approaching the diffuse topic of intercultural learning and development - Framework for intercultural learning and development - Implementation and results of the intervention study.
