This book is an essential resource for teachers seeking to understand the critical role that digital citizenship education plays in promoting a more informed, engaged, and responsible global citizenry. While digital technologies have opened up new opportunities for life-long learning, they have also given rise to emerging concerns, notably in relation to the rise of disinformation and hate speech online. Aimed at building the capacities of teachers to prepare learners to act ethically and responsibly in physical and digital environments, these guidelines stress the importance of considering how Global Citizenship Education (GCED) and related knowledge, values, skills and attitudes can be fostered for teaching, learning and engaging for a more sustainable, inclusive, just and peaceful world.
