J. Dewey (1859-1952), an American educator, psychologist, and philosopher, had a profound influence on American intellectual life throughout the twentieth century. He not only has research in the field of philosophy, but also delves into social issues, especially the renovation of American schools. He once said that the school must represent the present life, which is really as vivid as the children's life when in the family, where they live or on the playground. Dewey especially appreciates the role of education, considering education as the fundamental method of social progress and reform. Carrying out that role is the moral duty of the school. In the popular view of many Vietnamese and even educational administrators, the school's ethical mission is only to teach ethical subjects, and through other collective activities.
