Step-by-step explanation:
The movement led by John Dewey that discussed reforming schools, defining what school is, what a curriculum should be, and what teaching should entail is known as the Progressive Education Movement. This movement emerged against the backdrop of a broader societal push for reform through public education and encompassed a commitment to preparing young Americans for social and civic responsibilities. Central to Dewey's philosophy was the belief that education should be rooted in real-life experiences and encourage critical thinking to create an informed citizenry capable of participating in a democratic society. It was part of a larger Progressive reform effort that sought various changes in the social structure, government, business practices, and education to promote efficiency, fairness, and democracy. Education reformers like Horace Mann played significant roles in advocating for public education as a means to combat ignorance and cultivate morality, discipline, and academic competence.
