John Dewey was an American philosopher, psychologist, and educational reformer who lived from 1859-1952. He obtained his PhD in 1884 and later opened the Laboratory School in 1896, where he tested his progressive ideas about education. Dewey rejected a curriculum-centered view of education and instead proposed a student-centered approach where students interact with the curriculum to make their own knowledge. He believed the teacher's role is as a facilitator and that education should provide freedom and values to help students reach their full potential.
