This book makes a comprehensive, multi-disciplinary argument for investing in effective early childhood education programs, especially those that develop in children their proven natural capacity to construct knowledge by building meaningful relationships. Recent insights in the fields of law, policy, economics, pedagogy, and neuroscience demonstrate that these particular programs produce robust educational, social, and economic benefits for children and for the country. The book also provides legal and political strategies for achieving these proven benefits as well as pedagogical strategies for developing the most effective early childhood education programs. The book concludes by making visible the wonderful learning that can take place in an early education environment where teachers are afforded the professional judgment to encourage children to construct their own knowledge through indispensable learning relationships.
