초록

본 논문에서는 온라인평생교육원에서 제공하는 STEP의 온라인 서비스 수강생 15.7만여 명 및 51만여 건의 수강 데이터를 대상으로 기술 통계적 분석을 수행했다. STEP의 교육과정 유형인 기업맞춤, 상시제, 기수제에 따라서 각 유형별 수강생의 성적 분포를 분석하여, 그 성적의 분포가 10점 미만과 90점 이상이 다수인 극단적인 분포임을 확인하였다. 추가적으로, 미수료 수강생의 데이터를 대상으로 한K-평균 군집화를 수행하여 미수료 수강생들의 특성을 분석하였다. 그 결과, 30-40대, 여름에 수강한 수강생들의 미수료율이 높다고 확인하였다. 또한, 전체 수강생들의 수료 여부 정보에 대하여 의사결정나무 기법을 적용하여 분석한 결과 다수의 강좌를 수강하는 남성, 전문대졸 수강생들의 미수료율이 높다는 것을 알 수 있었다. 따라서, STEP 수강생들의 수료율을 높이기 위해 이러한 수강생들을 대상으로 학습을 더 독려할 필요가 있다.

In this paper, we conducted a descriptive statistical analysis on the data of about 157 thousands of students and 510,000 enroll data of the STEP online service provided by the Online Lifelong Education Institute. According to the classification such as company adaptation, regular and cardinal, we analyzed the distributions of students' grades for each classifications. As the result of analyzation, it was shown that the distribution of grades is extreme skewed such that there are large numbers of less than 10 points or more than 90 points. In addition, K-means clustering was performed on the data of uncompleted students to analyze the characteristics of them. As a result, it was confirmed that the non-completion rate of students in 30 s and 40 s ages who took the course in the summer, was high. Furthermore, as a result of applying the decision tree technique to the completion status information of all students, we found that the uncompleted rate of male and vocational college graduates taking a large number of courses was high. Consequently, we have to encourage learning to such STEP students in order to increase the completion rate.
