사설 인터넷 강의와 EBS 특강 수강이 수학능력시험 사회탐구 영역 성적에 미치는 영향 분석

Abstract

This paper investigates the effects of online private lectures and EBS lectures on the Scores of the Social Studies Inquiry Subject of the College Scholastic Ability Test (CSAT) using the 4th and 5th year Korea Education and Employment Panel that conveys some questionnaires regarding the CSAT. We used a method of two-stage least squares considering the endogeneity problem among variables and derived the following implications. First, the scores of the Social Studies Inquiry Subject are higher among the students who have an experience of private education. However, we could not find such results when we excluded students who did not study the subject after school. This result implies that private education is not necessarily superior to after-school studies in terms of public education when attempting to raise CSAT scores. Second, online private lectures do not yield statistically significant effects on CSAT scores compared to EBS lectures when we look into the group of students who took either online private lectures or EBS lectures. This result implies that the government policy that intends to relate the CSAT with EBS lectures might be effective in reducing households' economic burden for private lessons at least in the Social Studies Inquiry Subject.
