What role do practice tests play in the learning process according to educational research?

Practice tests serve a significant role in the learning process, primarily by enhancing retention of information and boosting confidence in content mastery. Research demonstrates that engaging in retrieval practice—such as taking practice tests—helps to solidify knowledge in long-term memory. This retrieval process not only reinforces what has been learned but also helps to identify areas that need improvement, promoting a deeper understanding of the subject matter.

Additionally, the experience of successfully completing practice tests contributes to a student’s self-efficacy, which is their belief in their ability to succeed in specific situations. As students see their progress over time, their confidence grows, making them more likely to perform better in actual assessment situations. This dual effect of retention and confidence building underscores the value of incorporating practice tests into the learning process.
