The dominance of North American (U.S. and Canadian) English is widely prevalent in Korean English language teaching (ELT). Students show more positive attitudes towards American English than any other English variety (Jung, 2005; Yook & Lindemann, 2013), and teachers impart and reinforce American English norms (Ahn, 2017; Ahn, 2011). Administrators and employers consider American English as the sole model for Korean ELT (Ahn, 2013; Harrison, 2010; Jenks, 2017; Song, 2013). Koreans’ preference for American English dates back to the 1950s, when the first national ELT curriculum explicitly favored American English over British English (Lee, 2015). Since then the status of American English as the standard among all varieties of English has been strengthened due to Korea's strong political, military, and economic ties with the US (Harrison, 2010; Yim, 2007).
