The purposes of this study were to review developmental stages of acculturation, to establish dimensions and components of intercultural communicative competence, and to suggest teaching methods in the elementary school based on the dimensions and the components of the stages. In order to achieve these purposes, theoretical research on the nature of intercultural communicative competence and teaching methods of intercultural dimensions and components was carried out in terms of developmental stages of acculturation. The stages of acculturation have relation to cognitive domain, affective domain, and cultural awareness. In the domain of cognitive development, the models such as Cummins (1981), Wong-Fillmore (1983), and Ausubel (1968) were presented. In the affective domain of second language research, the models of Gardener and Lambert (1972), Maslow (1954), and Bloom (1974) were argued. Modifying the models of Ausubel, Cummins, Wong-Fillmore, the dimensions and components of intercultural communicative competence were established. In addition, it was suggested that cultural syllabus and lesson plan based on tourist and survivor stage should be considered.
