Metacognitive awareness of the pretesting effect improves with self-regulation support

The pretesting or prequestion effect refers to the counterintuitive finding that taking tests on information that one has yet to learn, during which many erroneous responses typically occur, can benefit learning relative to nontesting methods (e.g., reading) if the correct answers are studied afterwards. Using a knowledge updating approach that entailed two or three cycles of pretesting versus reading followed by a criterial test, we investigated (a) the extent to which learners develop metacognitive awareness of the pretesting effect through experience (as evidenced by predictions of criterial test performance) and (b) three forms of external support—namely, performance feedback (displaying criterial test performance for pretested versus read items), prediction reminders (displaying learners’ predictions alongside performance feedback), and recall prompts (asking learners to remember criterial test performance during the first cycle prior to making predictions for the second cycle)—that might improve, or provide insights into, such awareness. Across five experiments, we found that learners generally lack awareness of the memorial benefits of pretesting, are predisposed to believing that reading is more effective even after repeatedly experiencing both techniques, and need support before they recognize that pretesting is more beneficial. Overall, these results underscore the challenge of, and highlight several means of dislodging, learners’ inaccurate beliefs about the efficacy of pretesting.
