Min Hyunsik Philosophy of Korean language education (KLE) is a research area that investigates various issues of KLE from a perspective of language educational philosophy. The controversial issues of the Korean language (KL) are values, status, language unification, and identity of KL. Several teaching issues of KL are the features and domains of the subject and curriculum of KL and contents structures and teaching orders in the curriculum. KLE should attach great importance to learners’ development of world view through KL texts. The Korean language education policy includes the issues of KLE and Korean language policy which has a direct influence on the policy of textbooks and entrance examination. We need to establish the communicative integration of KL, as well as to prepare for the language unification, to build grammar standardization, to revise orthographies, to compile a mega-corpus, and to improve the literacy of KL. Systematic Hanja education at elementary school is also necessary aside from the exclusive use of Hangeul. Korea has high linguistic vitality in terms of demographic capital, political capital, economic capital, and cultural capital. A strong theoretical foundation of philosophy of KLE produces good KLE policy that will make an effective influence on KLE.
