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 sociocultural 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.
