Learning is the foundation of the human experience. It begins at birth and never stops, a continuous and malleable link across life stages of human development. Disparities in learning access and outcomes around the world have deep consequences for income, social mobility, health, and well-being. For international development practitioners faced with today's unprecedented environmental and geopolitical pressures, learning should be viewed as a touchstone and target for those seeking to truly effect global change. This book traces the path of international development work―from its pre-colonial origins to the emergence of economics as the dominant discipline in the field―and lays out a new agenda for policymakers, researchers, and practitioners, from early education through adulthood. Learning as Development is an attempt to rethink international education in a changing world.
