Putting evidence-based claims to the test: A multi-site classroom study of retrieval practice and spaced practice
Abstract
Summary Retrieval practice and spacing out studying help increase learning. Introductory Psychology students at nine colleges/universities took quizzes with more (RP+) or less (RP−) retrieval practice and more (SP+) or less (SP−) spacing between quizzes. We compared (N = 351) scores on class exams and on a standardized test. We also measured key student variables (e.g., depth of processing). GPA predicted a significant portion of variance in exam scores, R2 = 0.05, F(1, 204) = 10.84, p = 0.001. We found a main effect for retrieval practice and a significant retrieval by spacing practice interaction, R2 = 0.28, F(3, 201) = 27.38, p < 0.001. Students using SP+, as well as those with SP− and RP−, scored higher than students using SP− and RP+. In practice, closer attention needs to be paid to quiz and exam content overlap and the duration within which repetition is used.

Too many exposures can lead to fatigue that negatively impacts learning.
“too many exposures can lead to fatigue that negatively impacts learning (Gurung & Burns, 2019).”

The negative impact of these factors fits with evidence that scheduling too many exposures to content can negatively impact learning through increasing students' fatigue from constantly reviewing the content.
“The negative impact of these factors fits with evidence that, in scheduling too many exposures to content, learning can be negatively impacted through increasing students’ fatigue from constantly reviewing the content (Gurung & Burns, 2019).”

The combination of spaced practice and spaced testing can influence learning.
“Given that the combination of these two related approaches to repeated exposure can influence learning (Gurung & Burns, 2019), clearly distinguishing between the effects of these two strategies is key to the success of their respective implementations in classrooms.”

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.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
