The objective of this book is to strengthen and systematize the effectiveness of global citizenship education through the use of new technologies, within and outside the school context. The aim is to provide theoretical basis and specific tools that can be used directly in educational activities, to promote critical thinking and the active involvement of young people in topics such as human rights, migration, climate change and the Sustainable Development Goals. Both the theoretical and practical sections have been laid out starting from the good practices already tested in several European countries, and the proposed educational methodologies intend to foster technology as an inclusive tool, therefore as an incentive for participation and dialogue between different cultures.
