“…Teachers often give students tests before they have even been taught the information being tested. A common motivation for doing so is to see what students might already know, but this practice of pretesting has also been shown to enhance learning (e.g., Grimaldi & Karpicke, 2012;Hartley, 1973;Hays, Kornell, & Bjork, 2013;Kornell, Hays, & Bjork, 2009;Richland, Kornell, & Kao, 2009;Simkins & Allen, 2000). Learners who receive a pretest before encoding to-be-learned information tend to remember that information better on a subsequent test than learners who are not given a pretest, an effect that is observed even if participants are unsuccessful at generating the correct information at the time of the pretest.…”
