This study is the process of finding answers to the following questions. Cultural content is needed to study Vietnamese language? Do Vietnamese language learners feel the need for classes using cultural content? Do Vietnamese teachers use cultural contents in class? In order to find out the answer, I conducted a questionnaire survey on Vietnamese students in Chungnam Foreign Language High School, interviewed teachers and analyzed the case examples. As a result of the questionnaires and interviews, it was found that the necessity of cultural contents development in Vietnamese language education is a requirement for both teachers and learners. Based on these results, we developed a case study on cultural education contents for Vietnamese language education. However, the model of teaching Vietnamese language utilizing cultural contents needs to be developed through more diverse academic analysis. Its effectiveness should also be investigated in depth. We will propose this as a future research project.
