“…Through the analysis of data on utilizing office hours and course grades, this study found: (1): Students who attended office hours typically earned higher scores on graded assignments, but not on proctored exams, (2): Students who sought help on assignments closer to the due date earned slightly lower final grades than those who got help earlier, and (3): Student use of staffed office hours follows the Pareto 80-20 rule where 80% of the staff time is spent answering questions from 20% of the students. [1,2] This paper provides background about the queue system and data sources used (Section 2), reviews related work about this topic (Section 3), analyzes the results (Section 4), and finally, discusses future work using the data in this paper combined with other sources of data (Section 5).…”
