Test-enhanced learning in medical education

Abstract

Context In education, tests are primarily used for assessment, thus permitting teachers to assess the efficacy of their curriculum and to assign grades. However, research in cognitive psychology has shown that tests can also directly affect learning by promoting better retention of information, a phenomenon known as the testing effect. Cognitive psychology research Cognitive psychology laboratory studies show that repeated testing of information produces superior retention relative to repeated study, especially when testing is spaced out over time. Tests that require effortful retrieval of information, such as short‐answer tests, promote better retention than tests that require recognition, such as multiple‐choice tests. The mnemonic benefits of testing are further enhanced by feedback, which helps students to correct errors and confirm correct answers. Application to medical education Medical educational research has focused extensively on assessment issues. Such assessment research permits the conclusion that clinical expertise is founded on a broad fund of knowledge and effective memory networks that allow easy access to that knowledge. Test‐enhanced learning can potentially strengthen clinical knowledge that will lead to improved expertise. Conclusions Tests should be given often and spaced out in time to promote better retention of information. Questions that require effortful recall produce the greatest gains in memory. Feedback is crucial to learning from tests. Test‐enhanced learning may be an effective tool for medical educators to use in promoting retention of clinical knowledge.

TL;DR

This narrative review argues that tests are not merely assessment devices but active memory modifiers, and that "test-enhanced learning" — frequent, spaced, effortful retrieval with feedback — could strengthen the clinical knowledge base underlying medical expertise. It synthesizes cognitive psychology laboratory evidence and maps it onto the history and priorities of medical education assessment.

Key findings

  • Repeated testing produces better long-term retention than repeated study. In Karpicke and Roediger's flashcard experiment with 40 Swahili–English word pairs, students in the standard and repeated-testing groups recalled approximately 80% of pairs on a test 1 week later, versus 36% (repeated study) and 33% (drop) — indicating that repeated retrieval, not continued study, drives retention.
  • More tests are better than fewer: students who took three tests on picture names recalled more 1 week later than those who took one test, who in turn recalled more than those not tested at all (Wheeler & Roediger).
  • Production tests (short-answer, fill-in-the-blank, essay) yield better retention than recognition tests (MCQ, true/false). In Butler and Roediger's art-history video lecture study, an initial short-answer test produced better retention on a final test 1 month later than an initial MCQ test or studying a lecture summary.
  • Feedback enhances the testing benefit by correcting errors and confirming correct answers; feedback containing the correct answer is critical, and delayed feedback sometimes produces superior retention relative to immediate feedback.

Methods

  • Design: narrative/conceptual review, not an empirical study; the authors state no new data were collected ("Ethical approval: not applicable").
  • Evidence base: cognitive psychology laboratory experiments on the testing effect, spacing effect, test format, and feedback, plus a review of the medical education assessment literature (MCQ vs OEQ, key features problems, script-concordance questionnaires, progress tests, in-training assessment).
  • Analysis: qualitative synthesis organized into three sections — testing research in cognitive psychology, the evolution of testing in medical education, and application of test-enhanced learning to medical education — concluding with recommendations for practice.

Limitations

  • Stated: most evidence for the direct effects of testing comes from laboratory experiments, and many applied studies occurred in simulated classrooms; testing benefits have not been fully studied in lectures, problem-based sessions, or clinical activities.
  • Stated: most "long-term" testing studies used retention intervals of less than 1 week, with a few up to 6 weeks, whereas medical trainees need to retain information for months to years, so efficacy over long periods is unestablished.
  • Stated: it is unknown whether improved test recall translates into retrieval during patient encounters or better patient care; the authors call for real patient outcome and care metrics as the strongest validation. Evident from the text: the paper offers no primary data, effect sizes, or meta-analytic synthesis of its own, so its recommendations rest on the cited studies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
