Quantitative Correlation between Student Use of Office Hours and Course Performance University courses with a significant computing component typically provide support forstudent learning in the form of open lab hours attended by instructional staff. Students visit theopen lab to work on computer-based assignments, and staff address questions as they arise,thereby providing just-in-time instruction and removing barriers to student progress. We havedeveloped an online queuing system that we use to schedule student assistance in many of ourcore computing courses. While electronic queuing systems have been used in computing labs fordecades, our web tool is instrumented to record a complete historical log of interaction timesbetween students and staff. The analysis presented in this paper is our attempt to understandwho uses the open labs, and what benefit, if any, they receive by doing so. Though we have recorded data over five consecutive semesters in three large classes, ourpreliminary analysis addresses a single semester (Spring, 2014) in a 500-student CS2 course. Inthis paper we examine queue use patterns in the context of regular assignment due dates, and wecorrelate staff-student interactions with student scores on exams and on programming projects.Most notably, we find: (1) student use of the lab resources accelerates near due dates (surprise!),(2) student use of staffed lab hours follows the 80-20 rule where 80% of the staff time is spentanswering questions from 20% of the students, (3) the 10% of students who use office hoursmost frequently perform significantly better on programming assignments (82.5 to 89.5 points,p=0.005) and generally better on exams (72.1 to 74.7 points, p=0.104) than the other students inthe course, and (4) students making only limited use of office hours (five or fewer questions persemester) see no statistically significant improvement in their course assessments. The full paper presents a multi-semester, cross-course quantitative analysis of student useof open lab assistance in programming-based CS courses, including correlation with courseperformance. We continue to use the online queue system in our courses and we are using theresults of the analysis to deploy staff resources more effectively and to adapt course policy to thereality of student study behaviors.
