Dewey emphasizes the present. According to him, the past is the past. The past and the future are nonsense unless they are connected with the present. He sees history as the past of the present, or the history of the prsent. And our aim of history education is to understand present social life. Dewey emphasizes economic and social history especially, because it is practical and expresses the process of growth of present life. In short, Dewey's theory of history, or history of education is also practical.
