The purpose of the article is to study Dewey's aesthetics and it's application in postmodern art education. The application is such as “Kaprow's Happenings” and “service-learning as postmodern art pedagogy”. Both Rorty and Hassan had ever mentioned that we should rethink the importance of Dewey's idea in postmodern world. Just as Dewey said about artistic objects in “Art as experience that “this ” task is to restore continuity between the refined and intensified forms of experience that are works of art and the everday events, doing, and sufferings that are universally recognized to constitute experience.” The concept of Dewey's aesthetics is different from what people think in traditional art, but it could be consistent with what postmodern artist think. In Dewey's aesthetics, “an experience” and “an artistics experience” are two important concepts different from so called “normal experience”. “An experience” of thinking has its own esthetic quality, and it could be enhanced to be “an artistic experience” when it had more intensity and meaning. To have an artistic experience, we must experience and feel sincerely, such as seeing, hearing, tasting, reason, feeling and positive passion.
