Abstract

Many universities stress gradually the importance of english-medium class in order to improve the international competitiveness and the internationalization of the university. In this paper, we compare english-medium class with korean class using course evaluation score. Also we analyze the factors that affect the effectiveness of the course evaluation score of english-medium class. First, logistic regression analysis is used to examine the main effects of subjects and individual characteristics. Also, decision tree analysis is used to examine the interaction effects for subjects and individual characteristics. The results of this paper are as follows. Grade, department category, class size, GPA and screening method affect the effectiveness of english-medium class. The highest effectiveness group of english-medium class is that grade is freshmen and department category is humanity. Also the group of the second highest effectiveness group is that grade is freshmen and department category is nature and art and GPA is high.

요즘 대부분의 대학들이 국제화를 목표로 재학생들의 어학능력 및 국제적 경쟁력 강화와 함께 영어강의의 중요성이 증대되고 있다. 본 연구에서는 강의평가점수를 이용해서 과목특성 변수들과 개인특성 변수들 별로 영어강의와 한국어강의의 효과성을 비교하였다. 또한 로지스틱회귀분석과 의사결정나무분석을 이용하여 어떤 요인들이 영어강의가 한국어강의에 비해서 효과적인지를 주효과와 상호작용효과 측면에서 분석하였다. 분석결과에 따르면 영어강의의 효과성에 영향을 미치는 변수로는 학년, 계열, 강좌규모, 평균평점, 계열, 전형방법 등으로 나타났다. 또한 영어강의 효과성이 특히 높은 그룹은 1학년이면서 인문계열인 경우, 그리고 1학년이면서 자연 및 예체능계열이고 평균평점이 높은 그룹이 높게 나타났다. 그리고 영어강의의 효과성 비율이 특히 낮은 그룹은 2-3학년 학생이면서 강좌규모가 크고 인문계열인 경우로 나타났다.
