Progressive education emerged in the early 20th century based on principles of social reform, children's interests and needs, and opposed autocratic teaching methods. Two main influences were John Dewey who founded a laboratory school emphasizing student choice, and Maria Montessori who believed education activities could influence development. During this era, schools became more diverse but many immigrant and minority students faced punishment for their native languages and disrespect of their cultures. The progressive education movement declined after WWII as its approach was seen as too soft.
