||Kwon, Jeong Hye & Lim, Jeongwan. (2018). An analysis of the topics and cultural contents in high school English textbooks under the national curriculum revised in 2015. The Linguistic Association of Korea Journal, 26(3), 117-137. The purpose of this paper is to investigate the topics and cultural contents in Korean High School English textbooks currently authorized by the national curriculum revised in 2015. A total of 11 authorized High School English textbooks are carefully examined, focusing on the topics and cultural contents of the main texts, for four categories: 1) the core competencies of the English curriculum revised in 2015, 2) the cultural topics, 3) the cultural background countries, and 4) the types of learning activities. The results of the study indicated that: First, the key competencies were distributed relatively evenly throughout all textbooks, and the most frequently introduced capability was civic competency. Second, among 19 cultural topics, the most common was general culture in these textbooks. Third, regarding the nationalities related to cultural background, native English cultures showed the highest distribution. Finally, almost all of the textbooks presented information retrieval activities and communication activities, but only some of them had hands-on activities. Based on these findings, the study provides pedagogical implications for cultural teaching and learning in English textbooks in Korea.
