John Dewey is probably most famous for his role in what is called progressive education. Progressive education is essentially a view of education that emphasizes the need to learn by doing. Dewey believed that human beings learn through a ‘hands on’ approach. This places Dewey in the educational philosophy of pragmatism.
Pragmatists believe that reality must be experienced. From Dewey’s educational point of view, this means that students must interact with their environment in order to adapt and learn. Dewey felt that the same idea was true for teachers and that teachers and students must learn together. His view of the classroom was deeply rooted in democratic ideals, which promoted equal voice among all participants in the learning experience.
