The purpose of this study is to consider the contextual meaning of subject-matter in primary education by conceptual investigation. The meaning of subject-matter has not been differentiated to various educational stages. Nevertheless, if it is possible to differentiate the meaning of subject-matter according to educational contexts, it is significant what\'s the meaning of subject-matter for primary education is discussed. The relevance between education and the contexts of life makes the contexts of education. Primary education as a contextualized language could be recognised as development for the whole being and preparation for the foundations for child\'s the future. In this manner, the subject-matter for primary education is intrinsic as well as instrumental in that it facilitates the present interests and needs of child and prepares foundations necessary for the future life of child. In this paper, the meaning of subject-matter for primary education is following : 1) the development of the characteristic and the initiation for social life, 2) the acquisition of practical wisdom and the formation of value, 3) the dialectical development through objectification of subjectivity. In effect, the meaning of subject-matter for the context of primary education could be founded only when we recognize the meaning of education as the process of life and acknowledge the unique values of various educational contexts.
