초록
본 연구는 대구시에 위치한 중학교 1개교에 재학 중인 266명의 중학생을 대상으로 인공지능 기반 적응형 학습 프로그램을 제공하는 온라인학습기기가 학생들의 학업성취도에 미친 영향을 무작위통제실험 방식으로 분석하였다. 기초 및 기말 진단고사 성적 변화를 분석한 결과, 통계적으로 유의미한 온라인학습기기의 평균처치효과는 관찰되지 않았다. 하지만 분위회귀분석을 통해 하위 10% 학생들의 학업성과가 0.358 표준편차만큼 통계적으로 유의미하게 증가함을 확인하였다. 처치집단 학생들의 저조한 프로그램 출석률과 수행률을 고려할 때, 인공지능 기반 적응형 학습 프로그램의 수용성을 높이기 위한 다양한 방법을 탐색하는 연구가 선행될 필요가 있다.
Abstract
We investigate the impact of artificial intelligence-based adaptive learning program provided to 266 students in one middle school in Daegu city, South Korea. While examining the difference between the baseline and endline academic performance, we do not find the average treatment effect of the adaptive learning program. However, the quantile regression analysis by deciles shows that there is 0.358 standard deviation improvement for the first decile group. Given the very low attendance and task completion rates of the adaptive learning program, how to increase the adoption for this type of education technology is a prerequisite for the future research
