AI 中文总结
该研究针对CS1课程截止日期附近办公时间拥堵问题，实施分段截止日期政策，证实其可提升办公时间效率且学生认可度高，为同类政策实施提供参考。
AI 中文摘要
计算机科学课程的办公时间利用率会在截止日期附近激增，导致等待时间过长、学生不满以及工作人员过度劳累。为解决该问题，一门大型CS1课程实施了分段截止日期政策：学生被随机分为两组，作业的发布和截止日期错开，两组完成作业的时间相同，但每个截止日期对应的学生数量减少了一半。本研究评估该政策的有效性，测量截止日期附近的办公时间利用率和工作人员效率，考察其对学生成绩的影响，并调查学生对该政策公平性和有效性的看法。总体发现，分段截止日期政策提升了办公时间效率，两组学生成绩无显著差异，多数学生认为该政策公平且有效。本经验报告还包含相关反思和学生反馈，指出了实施及进一步改进类似政策的方法。
英文摘要
Office hour utilization in computer science courses can spike near deadlines, producing long wait times, frustrated students, and overworked staff. To address this problem, a large CS1 course implemented a split deadlines policy. Students were randomly divided into two groups with staggered release and due dates. Each group had the same amount of time to complete assignments, but the number of students with each due date was reduced by half. Our study evaluates the effectiveness of this policy. We measure office hour utilization and staff efficiency near deadlines, examine the policy's impact on student performance, and investigate student perception of the policy's fairness and effectiveness. Overall we found that the split deadline policy increased office hour efficiency, resulted in no significant difference in performance between groups, and was considered fair and effective by most students. Our experience report includes reflections and student feedback indicating how to implement and further improve similar policies.
