Retrieval Practice
3 studies
Retrieval practice means attempting to recall information rather than only viewing it again. Flashcards and practice questions can support retrieval when the learner attempts an answer before seeing it. Feedback and the comparison activity matter: retrieving with corrective feedback is not the same intervention as unsupported recall, and ordinary rereading is not the same as rereading targeted key statements.
This page connects controlled passage and vocabulary experiments with a medical-school flashcard cohort. It distinguishes recall, transfer and exam scores, and keeps experimental benefits separate from app-use associations.
How does retrieval practice compare with rereading?
Start with the findings and their cited studies, then compare the boundaries below.
The advantage depends partly on what the rereading comparison receives.
Attempted recall and useful feedback need to be considered together.
Before applying these findings
Check whether an answer was attempted before feedback, what the comparison group saw, and whether the outcome measures recall, transfer or examination scores. Keep self-selected app use distinct from an experiment.
A tension to inspect
Laboratory transfer questions, delayed word translations, and medical-school examinations are different outcomes. These studies do not isolate a single retrieval mechanism or establish transfer to clinical work.

Does retrieval practice beat rereading when key information is matched?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Who participated and how large was the analysed sample?
Fifty-six people participated in the study and were rewarded with course credits.
What is the main limit on applying this result?
That is, it becomes clear that the effect of retrieval practice might be partly attributed to the focused exposure to key information (i.e., the feedback).

Do spaced sessions and feedback improve vocabulary recall?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
What was the main finding?
In support of H1, participants in which learning was distributed the most (four sessions) had the highest recall performance (M = 77.2, SD = 29).
What is the main limit on applying this result?
The levels of the variable Spacing (one, two, or four sessions) were equally distributed among the experimenters, but the participant allocation to the levels was not done entirely at random: the rigid scheduling of several sessions would have made it impossible for some to participate.

- Attempted recall and useful feedback need to be considered together.
- Higher scores among users are evidence of association, not an app treatment effect.
Largest unresolved question
Laboratory transfer questions, delayed word translations, and medical-school examinations are different outcomes. These studies do not isolate a single retrieval mechanism or establish transfer to clinical work.
Common misconceptions
Rereading is useless.
In the transfer experiment, rereading targeted key statements performed better than plain rereading and reduced the retrieval advantage.
More retrieval trials always improve recall.
The vocabulary study found no overall retrieval-proportion effect; corrective feedback changed the result.
The evidence validates PaperFren or NoteFren flashcards.
None of these studies evaluated either product. A format-level rationale is not a product efficacy trial.

What the evidence shows
Drawn from 3 studies in this library. Mix labels say which citation roles are present; they are not a strength score. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope.
The advantage depends partly on what the rereading comparison receives.
Retrieval practice with feedback outperformed plain rereading on transfer questions after one week. In a second experiment, rereading plus key statements narrowed the difference, although retrieval still performed better.
Attempted recall and useful feedback need to be considered together.
In the vocabulary web experiment, a higher proportion of retrieval trials had no overall main effect. Corrective feedback interacted with retrieval frequency; more testing by itself was not reliably better.
Higher scores among users are evidence of association, not an app treatment effect.
Anki flashcard users had higher course-end and year-end exam scores than never-users after MCAT adjustment. Self-selection, other resources and small later subgroups prevent a causal claim about flashcards improving exam performance.

Papers
3 studies in this library bear on Retrieval Practice, ordered by citations.
- Are Anki flashcards associated with higher medical-school exam scores?
Anki users had higher examination scores in one medical-school cohort after adjustment for MCAT scores, but self-selection prevents a causal conclusion.
- Does retrieval practice beat rereading when key information is matched?
Retrieval practice with feedback improved transfer over rereading, but much of the advantage shrank when rereading also highlighted the information needed for the final test.
- Do spaced sessions and feedback improve vocabulary recall?
German-speaking learners recalled more Finnish vocabulary after distributed sessions, while retrieval trials benefited from corrective feedback; spacing groups were not fully randomised.

How does retrieval practice compare with rereading?
Retrieval with feedback performed better than plain rereading on the selected one-week transfer test. The advantage became smaller when rereading included the key information supplied as feedback. Compare feedback, information exposure and time on task before attributing the entire result to retrieval.
Do flashcards improve exam performance?
The selected Anki cohort found higher scores among users after MCAT adjustment, but did not randomly assign flashcard use. It supports an association rather than proof of causation, and cannot establish an optimal daily card count or validate PaperFren or NoteFren.
