The present study aims to examine the realization of language immersion education for FLE (Français Langue Étrangère) and CLE (Coréen Langue Étrangère). Foreign Language teachers’ role has been recently concerned as to find out the interaction between a teacher and a learner in language immersion education. The success of language immersion education depends on the learners’ attitudes and motivation. The learners’ motivation can be enhanced through the electronic sources online made by the nonnative language teachers or through the extra-curricular language activities. The findings of the present study are summarized as follows. First, the teachers must perceive learners’ first language and culture to accomplish a successful interaction. Second, the foreign language policy should favor not only English, but also other various languages as well. Third, the feedback through the self-evaluation should be followed by its purposes and types.
