在计算机科学（CS）教育中，教师利用办公时间进行一对一的求助。先前的研究表明，传统的面对面办公时间可能没有得到充分利用。作为回应，许多教师正在增加或过渡到虚拟办公时间。我们的研究重点是比较面对面和在线办公时间，以调查使用面对面和虚拟办公时间的学生的表现、互动时间和特征之间的差异。我们分析了一个丰富的数据集，涵盖了CS2课程的两个学期，该课程在2019年秋季使用了面对面的办公时间，在2020年秋季使用了虚拟办公时间。我们的数据包括学生对办公时间的使用、问题的性质、接受帮助的时间以及人口统计和态度数据。我们的研究结果显示，学生在办公时间的出勤与课堂表现没有关系。然而，我们发现女学生更频繁地参加办公时间，在计算机方面思维固定的学生和理论应用能力较弱的学生也是如此。我们还发现，对计算机科学不自信或不喜欢计算机科学的学生在虚拟办公时间更活跃。最后，我们观察到参加虚拟办公时间的学生与CS学习兴趣的增加之间存在显著的相关性；而参加面对面办公时间的学生往往表现出成长心态的增加。
In Computer Science (CS) education, instructors use office hours for one-on-one help-seeking. Prior work has shown that traditional in-person office hours may be underutilized. In response many instructors are adding or transitioning to virtual office hours. Our research focuses on comparing in-person and online office hours to investigate differences between performance, interaction time, and the characteristics of the students who utilize in-person and virtual office hours. We analyze a rich dataset covering two semesters of a CS2 course which used in-person office hours in Fall 2019 and virtual office hours in Fall 2020. Our data covers students' use of office hours, the nature of their questions, and the time spent receiving help as well as demographic and attitude data. Our results show no relationship between student's attendance in office hours and class performance. However we found that female students attended office hours more frequently, as did students with a fixed mindset in computing, and those with weaker skills in transferring theory to practice. We also found that students with low confidence in or low enjoyment toward CS were more active in virtual office hours. Finally, we observed a significant correlation between students attending virtual office hours and an increased interest in CS study; while students attending in-person office hours tend to show an increase in their growth mindset.
