Retrieval Practice

A Knowledge of retrieval practice accumulated unevenly across lessons, revision and professional training. A striking report could establish that a pattern existed, yet it could not show whether retrieval route operated elsewhere. Researchers examining retrieval practice therefore moved toward shared definitions and planned comparisons based on practice testing rather than discarding the earlier record. B For the present account of retrieval practice, trying to recall information can strengthen later memory more than simply reading the same material again. In cognitive psychology, the term testing effect refers to the learning benefit produced by actively retrieving information. The definition gives researchers a common starting point for discussing retrieval practice, but it does not identify a cause by itself. Two observations of retrieval practice can share the label testing effect while differing in scale, timing or origin. C The evidence about retrieval practice is informative but conditional. One point relevant to retrieval practice is that retrieval practice benefits retention and sometimes transfer, especially when feedback corrects errors. Researchers test retrieval route as an explanation. Evidence reviewed for retrieval practice shows that successful recall reinforces the cues and pathways used to reach stored knowledge. Confidence in retrieval route rises when independent measures of retrieval practice agree and rival explanations fail, rather than when a single comparison happens to be statistically precise. D Researchers rely chiefly on practice testing to investigate retrieval practice. Research on retrieval practice has found that learners complete low-stakes recall or restudy, receive controlled feedback and take a delayed final test. They decide their comparison, exclusions and outcome measures for retrieval practice in advance. A result about retrieval practice is treated as stronger when it survives more than one source of evidence, not simply when one instrument measuring retrieval practice reports many decimal places. E Practical programmes translate evidence about retrieval practice into action. The discussion of retrieval practice notes that teachers use brief quizzes, flashcards and explanation prompts as learning activities rather than only as grading. Their stated focus is knowledge retention. Teams working on retrieval practice compare later outcomes with conditions before implementation and record unintended effects. This evaluation of retrieval practice determines whether the original explanation involving retrieval route remains useful outside the research setting. F Interpretation of retrieval practice must stop short of a universal claim. For the present account of retrieval practice, poorly designed tests may reward isolated facts, and repeated confident errors can persist when feedback is missing. Future work on retrieval practice is organised around transfer-focused tasks. For future research on retrieval practice, transfer-focused tasks will test whether learners can apply retrieved knowledge in unfamiliar problems. This use of transfer-focused tasks targets a specific uncertainty about retrieval practice rather than merely increasing the volume of data.
