Dr. Sarah Chen teaches Biology 101, an introductory course required for all life science majors. Her lectures are held three times per week in a 250-seat auditorium, with 180 enrolled students. State regulations require attendance tracking for funding compliance, but manual methods were consuming too much time.
Before DataScan, Dr. Chen passed around paper sign-in sheets. Students in the back rows often didn't receive the sheet until 15 minutes into the lecture. Buddy signing was rampant - she suspected at least 20-30 signatures per class were fraudulent. Collecting and filing the sheets, then manually entering attendance data took her graduate assistant 3-4 hours every week.
Now, her teaching assistant Meera arrives 10 minutes early and sets up an iPad at the auditorium entrance. As students flow in for the 9:00 AM lecture, they scan their IDs in 2-3 seconds each. By 9:00 AM, 174 students have checked in. Six late arrivals scan between 9:05-9:15, automatically marked as late by their timestamps.
After the 9:50 AM lecture ends, Meera exports the attendance file. It takes 10 seconds. The file shows 180 unique student IDs with exact arrival times. During her office hours, Meera imports the file into Banner - the university's student management system - which automatically updates all attendance records and emails absent students a reminder about the attendance policy.
Results have been transformative. No lecture time is wasted on roll call. Buddy sign-ins have been completely eliminated - you can't scan someone else's physical ID card from across the room. Students who are struggling with attendance are identified immediately, allowing early intervention. And Dr. Chen's teaching assistant saves 3 hours every week that can now be spent helping students understand course material.
The Numbers: Before and After
Before DataScan: 15 minutes per class wasted on attendance, 3-4 hours/week for data entry, estimated 20% fraudulent signatures. After DataScan: 6-8 minutes pre-class check-in (no lecture time lost), 10 minutes/week for exports and imports, 0% fraudulent attendance. Time saved: 6+ hours per week.
