“…A loftier goal for teachers is that students completing cumulative exams will retain course-related information for a long period of time beyond the end of the semester. Unfortunately, some researchers suggest that students do not retain much content knowledge after completing their introductory courses (Rickard, Rogers, Ellis, & Beidleman, 1988; Spitzer, 1939; VanderStoep, Fagerlin, & Feenstra, 2000; however, see Scepansky & Carkenord, 2004, for dissenting conclusions) and that students experience this decay of knowledge relatively quickly after the semester ends (e.g., in less than 17 days; Bunce, VandenPlas, & Soulis, 2011). However, in the short term, Bunce, VandenPlas, and Soulis (2011) found that cumulative exams were one of several pedagogical techniques that may prevent the decay of student knowledge over the short term (i.e., 17 days).…”
