What should students learn to best prepare for the twenty-first century?In this book, the Center for Curriculum Redesign (CCR) describes a framework built to address this question, so that curriculum is redesigned for versatility and adaptability, to thrive in our volatile present and uncertain future. The framework focuses on knowledge (what to know and understand), skills (how to use that knowledge), character (how to behave and engage in the world), and meta-learning (how to reflect on and adapt by continuing to learn and grow).This book is essential for teachers, department heads, heads of schools, administrators, policymakers, standard setters, curriculum and assessment developers, and other thought leaders and influencers, who seek to develop a thorough understanding of the needs and challenges we all face, and to help devise innovative solutions.
