Korean Language Education and English Education in Korea －Effects of English Education on Korean Language Education－ Hwang, Jong-bai The present study reviews previous studies which have investigated the effects of foreign language education on the acquisition or education of native language, and explores an effective way of Korean language education which considers the positive or negative effects of English education on Korean language education. Most of negative effects of foreign language learning have been found in the area of native language attrition, which is not important in the context of English education in Korea. Positive effects have been more frequently reported than negative effects in the areas of native language pronunciation, grammar, learners' cognitive ability, and native language literacy. Unfortunately, there have been few studies which investigate the effects of English education on Korean language in Korea. Future studies which try to find the effects, positive or negative, of English education on many aspects of Korean language education are required for planning and implementing appropriate policies of Korean language education.
