#TIL Nature Human Behaviour: 早八影响睡眠并降低绩点

Attending classes and sleeping well are important for students’ academic success. Here, we tested whether early morning classes are associated with lower attendance, shorter sleep and poorer academic achievement by analysing university students’ digital traces. Wi-Fi connection logs in 23,391 students revealed that lecture attendance was about ten percentage points lower for classes at 08:00 compared with later start times. Diurnal patterns of Learning Management System logins in 39,458 students and actigraphy data in 181 students demonstrated that nocturnal sleep was an hour shorter for early classes because students woke up earlier than usual. Analyses of grades in 33,818 students showed that the number of days per week they had morning classes was negatively correlated with grade point average. These findings suggest concerning associations between early morning classes and learning outcomes.
上课和良好的睡眠对学生的学业成功非常重要。我们通过分析大学生的数字痕迹测试了早晨早课是否与低出勤率、较短的睡眠时间和较差的学业成就相关联。对23,391名学生的Wi-Fi连接日志分析结果显示,8:00的课程出勤率比较晚开始的课程低约十个百分点。对39,458名学生的学习管理系统登录日志和181名学生的动作记录数据的日节律模式分析显示,早课导致夜间睡眠时间短了一小时,因为学生比平时早起。对33,818名学生成绩的分析显示,每周上早课的天数与平均成绩点数(GPA)呈负相关。这些研究结果表明,早晨早课与学习成果之间存在令人担忧的关联。
