The present study aimed at investigating the awareness of linguistic culture and education of linguistic culture from teachers and students in the Washington D. C. area and at finding the implication of the education of linguistic culture. The following is the result of this investigation. First, as education of culture should consider the students’ needs, the education of linguistic culture amongst education of culture which particularly is useful to learn Korean language should be considered importantly. Second, arranging the teaching and learning method and educational content should be given priority over any others in relation of the education of linguistic culture. Third, usually teachers respect the students’ need and they have the will to apply it in the teaching-learning situation. It is also necessary to narrow the perceived gap between the teachers and students through a number of case studies and researches about education of linguistic culture. Fourth, that there is the difference between heritage students and non-heritage students should be considered when teaching. It may be difficult to generalize these findings due to the nature of the case study. However, such study needs to be conducted persistently as concrete and rich data from accumulated case studies such as the present study would make it possible to find general principles about education of Korean culture.
