Carpenter reviews evidence that retrieval practice can improve not only retention of previously tested information but also transfer to new situations. The studies considered vary the delay between learning and application, the format of practice and final tests, and the knowledge domain or context.
Across this emerging literature, retrieving information often produces advantages over additional study even when the later task is not identical to practice. Proposed explanations include strengthening accessible memory representations and encouraging organisation or elaboration that supports flexible use. The review is cautious because the transfer literature was still small and transfer can take many forms. For educators, the findings support asking learners to retrieve and apply ideas through varied questions, formats, examples, and delays rather than repeating one test type.
Retrieval should be designed around meaningful knowledge and followed by feedback when errors could otherwise persist.
A transparent research trail
Each entry identifies the volume, edition, chapter or appendix in which the work appears.
Evidence summaries explain the central idea and why the source matters to educators.
Entries link to lawful full text where available, or to a publisher, library or purchase page.
References are checked against publisher records, scholarly indexes, DOI or ISBN metadata, repositories and author records where available. An entry marked [Citation not verified] preserves the wording found in the relevant volume without attributing findings to an unconfirmed work.
