The document summarizes the major debates around curriculum in American education from 1900 to the present. It discusses four major perspectives: the humanists who advocated for a classical curriculum focused on the humanities; the social efficiency educators who wanted schools to produce students ready for the workforce; the developmentalists who believed curriculum should follow child development; and the social meliorists who saw schools as vehicles for social change. Key figures like Dewey attempted to synthesize these perspectives, while advocates for progressive education criticized rigid, subject-focused curriculum.
