Cognitive perspectives on maintaining physicians’ medical expertise: IV. Best practices and open questions in using testing to enhance learning and retention

Abstract

Although tests and assessments—such as those used to maintain a physician’s Board certification—are often viewed merely as tools for decision-making about one’s performance level, strong evidence now indicates that the experience of being tested is a powerful learning experience in its own right: The act of retrieving targeted information from memory strengthens the ability to use it again in the future, known as the testing effect. We review meta-analytic evidence for the learning benefits of testing, including in the domain of medicine, and discuss theoretical accounts of its mechanism(s). We also review key moderators—including the timing, frequency, order, and format of testing and the content of feedback—and what they indicate about how to most effectively use testing for learning. We also identify open questions for the optimal use of testing, such as the timing of feedback and the sequencing of complex knowledge domains. Lastly, we consider how to facilitate adoption of this powerful study strategy by physicians and other learners.
