教师面临的挑战是鼓励学生提交经过良好测试的高质量代码，同时与autograder的双刃剑作斗争。虽然自动评分器可以快速向学生提供反馈，但学生可能会依赖自动评分器作为确定代码正确性的主要手段。本着类似的精神，教师也经常提倡尽早提交，不要等到最后一秒。为了鼓励学生提交更少的错误提交和完成编程作业，我们研究了两个实验室提交政策，时间限制提交和点限制提交，在连续学期的大型计算机体系结构课程。我们调查学生对这两种政策的看法，并分析实验数据，并在两个学期之间进行比较。我们的初步结果表明，虽然学生喜欢的时间限制政策，点限制政策是积极影响学生的正确提交的百分比，以及学生提交正确的意见书更早。
Instructors face the challenge of encouraging well-tested, quality code submissions from students while battling the double-edged sword of the autograder. While autograders can provide feedback to students quickly, students can become reliant on the autograder as the primary means for determining correctness of their code. In a similar spirit, instructors also frequently promote submitting early and not waiting until the last second. To encourage students to submit fewer erroneous submissions and completing programming assignments earlier, we examine two lab submission policies, time-restricted submissions and point-restricted submissions, implemented in consecutive semesters of a large Computer Architecture course. We survey students on their perception of these two policies and analyze the lab data and compare between the two semesters. Our initial results show that while students preferred the time-restricted policy, the point-restricted policy is positively affecting students' correct submission percentage, as well as students submitting correct submissions earlier.
