John Dewey was an early 20th century educational reformer who advocated for a progressive approach focused on meeting students' needs and involving them in planning their education. He felt the traditional system was too authoritarian and did not adequately prepare students for participation in a democracy. Dewey believed learning should be interactive and build on students' interests and experiences rather than just transmitting facts. While progressive education gave students more freedom, Dewey argued it still needed structure to maximize learning. His ideas challenged the traditional system but some aspects remain today.
