Despite dramatic, sweeping changes in recent decades, a strong case can be made for guiding the reformation of contemporary public education in the United States on common school ideology of the nineteenth century. The author argues that the common school remains a public institution capable of preparing America's youth to contribute to the community in a positive manner, and that education must be treated at a public good where all children-regardless of social class-have a right to a quality education. The work includes a thorough overview of Horace Mann's writings on K-12 public education that support the common school ideal-concepts that are over 150 years old, yet still highly relevant today.
