This essay indicates that education is a subject concerning humans. Humans not only fail to stay away from sociality but also are endowed with the quality of Being. Thus educational problems consist of the problem of human being and existence. Heidegger revealed the necessity for explicitly restating the question of Being. He took the ontological analytic of Dasein as laying the horizon for an interpretation of the meaning of Being and existential constitution in general . Another hand, in this process of questioning anew the meaning of Being , Heidegger overtook a strait of antagonism which raised by traditional epistemology and thereby to establish firmly base for ontology which rooted Dasein . Based on this , this essay, by analyzing hermeneutic phenomenology of Heidegger , intends to manipulate the methodology of education on the basis of existential-ontology and to point out the possible contribution in educational studies.
