초록

본 논문에서는 학업성취도가 낮은 학생이 학업성취도가 보통 이상 학생의 학업성취도에 미치는 친구효과를 추정하였다. 친구효과 추정을 위해 2009년에 시행되었던 학력향상중점학교 정책이 수반하는 회귀불연속설계를 이용하였다. 중학교를 대상으로 한 국가수준 학업성취도 평가 전수 자료를 이용하여 분석한 결과, 이러한 친구효과는 존재하였음을 확인하였다. 구체적으로는 학력향상중점학교 정책으로 학업성취도 미달학생 비중이 1%p 감소할 때, 보통 이상 학생의 비중이 5%p 이상 증가하였다. 더 나아가서 이러한 친구효과는 다양한 강건성 검정 하에서도 여전히 존재함을 보였다.

This paper estimates the peer effect of how improving the under-performing students can affect the academic performance of other students, focusing on the ratio of students more than proficient. We take advantage of the regression discontinuity design of the policy assignment rule of School-for-Improvement (SFI), which targeted the under-performing schools as an identification strategy. The estimation results from the 2009-2010 NAEA (National Assessment of Educational Achievement) reveal that the decrease of the ratio of under-performing students tends to increase the ratio of excellent or proficient students at around the policy cutoff. The finding turns out to be robust to various falsification tests.
