Progressive education aims to bring democratic ideals into the classroom by respecting diversity and developing critical thinking skills. It began in the late 19th century as Americans questioned education's role in creating uniform citizens. Progressive educators like John Dewey wanted schools to teach community and participation. Dewey tested his ideas in a laboratory school and others later founded the Progressive Education Association to promote child-centered, socially focused learning through projects and collaboration rather than separate academic and vocational training. While progressive schools still exist, their ideals became less accepted in the 1950s amid Cold War fears and conservatism, though modern public education seeks a balance with traditional methods.
