The global movement to educate all children has produced one of the most remarkable silent revolutions experienced by humanity, integrating most children and youth into institutions invented to pass on to them what each generation considers valuable, and to help them develop the competencies to improve the world. Changes in a range of domains, from technology to politics, from the ways in which we communicate and associate, to the ways in which we produce goods and services, continue to expand our aspirations for how schools should prepare the young to invent the future. There is much innovation worldwide responding to this aspiration, and the need to bring such innovations to scale so they benefit all children. The contributors to this book explain what the opportunities and challenges are to scale educational change to make schools relevant to the demands of our times. Based on a Think Tank convened by the Global Education Innovation Initiative at Harvard University, this book aims to stimulate broad social dialogue on how to support students and teachers to live fulfilling lives in the volatility and complexity of our times.
