(Dis)Organization and Success in an Economics MOOC
研究发现，在经济学慕课中，晚注册一天的学生获得证书的概率低17个百分点，这种差异与人口特征、动机或能力无关，表明课程组织性不足是导致低完成率的原因之一。
Massive Online Open Courses (MOOCs) present the potential to deliver high quality education to a large number of students. But they suffer from low completion rates. This paper identifies disorganization as a factor behind failure to complete a MOOC. Students who enroll one day late are 17 percentage points less likely to earn a certificate than students who enroll exactly on time. This reflects selection, but it does seem to be related to demographic characteristics, motivation to complete the course, or ability. This suggests that building in even more structure in the MOOC could be a factor in improving performance.
