Drawing on a synthesis of research and practice in global citizenship education, this book presents The World Course--a rigorous and coherent curriculum to foster student agency, empathy, and deep knowledge and skills to recognize the biggest global challenges and opportunities of our times, and to advance sustainability, human rights, and peace. Integrating current thinking on twenty-first-century competencies and deeper learning, and deploying pedagogies that cultivate student responsibility, imagination, and creativity, such as project-based learning and design thinking, this book is a blueprint to reinvent education to empower global citizens.
