Figure 2.

Average time in minutes (+/− SE) that students were engaged with course material under two different course grading scenarios. Students working under a tiered grading scheme spent significantly more time viewing a 15-minute video than students working under a more traditional grading scheme (traditional refers to a lecture course where exam scores made up 75% of each student’s final grade (n=21); tiered refers to a course that used the tiered grading scheme shown in Figure 1 (n=24); t-test p<0.05). The course material shown here was a single 15-minute video clip on the action potential). Total student time spent engaged with the material was recorded across sessions by the course management software where the videos were hosted. Similar results were obtained for all course material analyzed.
