Choi, Jin-sook. 2017. “International Students' Attitude Changes towards English as per their Korean skills”. The Sociolinguistics of Korea Journal 25(3). 327~349. This study aims at identifying the international students' attitudes towards English change as per their Korean skills after learning English over one semester. Sixty international students, who consisted of three groups as per their Korean skills, participated in the questionnaire survey at the beginning stage of the class. After one semester, the same questionnaire was given to the participants. Two questionnaire surveys showed similar results: the participants with a higher level of Korean skills demonstrated more favorable attitudes towards English and were less fearful in learning English, compared to those with a lower level of Korean skills. The attitude changes were also different as per the Korean skills: when compared to the attitudes at the beginning, while the participants with a higher level of Korean skills changed more favorably towards learning English, the participants with a lower level of Korean skills showed no attitude changes or picked up less favorable attitudes, and their fear about learning English rather increased. This study implies that English learning may improve English skills for the international students with a higher level of Korean skills but does not affect those with a lower level of Korean skills.
