Mean number of core concepts (CC) at the pre-test, final exam, and post-test for the plant item (A) and animal item (B) in both the regular and extra credit participation incentive conditions. The students in these plots reflect those who completed the assessments at all three time points. In the interest of space, please note that the x-axis of the graphs is not to scale and thus, does not represent the chronological time distance between each test administration time point. The pre-test and final exam were 13–14 weeks apart and the final exam and post test were less than two weeks apart
