Subclaims¶

q3 i2 Rowland's (2014) meta-analysis, as reported in the chapter, found g = 0.69 at retention intervals greater than 1 day. → Karpicke 2017 q3 i2 The same meta-analysis found a smaller but still positive effect, g = 0.41, at retention intervals less than 1 day. → Karpicke 2017 (2)

Evidence¶

Karpicke 2017¶

Karpicke, J. D. (2017). Retrieval-Based Learning: A Decade of Progress. Learning and Memory: A Comprehensive Reference, 2nd edition, Volume 2. https://doi.org/10.1016/B978-0-12-809324-5.21055-9

q3 · i2 · medium effect, g = 0.69 · review · r3

The chapter reports Rowland's (2014) meta-analysis of 159 effect sizes: effects "were larger at retention intervals greater than 1 day ( g ¼ 0.69)" than at shorter intervals.

"In Rowland’s (2014) meta-analysis, based on data from 159 effect sizes, retrieval practice effects were larger at retention intervals greater than 1 day ( g ¼ 0.69) relative to reten- tion intervals less than 1 day ( g ¼ 0.41)."

q3 · i2 · medium effect, g = 0.41 · review · r3

In the same meta-analysis reported by the chapter, the effect at "tion intervals less than 1 day ( g ¼ 0.41)" was smaller than at intervals greater than 1 day.

"In Rowland’s (2014) meta-analysis, based on data from 159 effect sizes, retrieval practice effects were larger at retention intervals greater than 1 day ( g ¼ 0.69) relative to reten- tion intervals less than 1 day ( g ¼ 0.41)."

Discussion¶

Related Claims¶

• Retrieval Practice Enhances Long Term Retention
• Retrieval practice produces reliable positive effects at short delays, although some forgetting must set in so that the final test is not at ceiling — related
• Retention interval moderates the testing effect: effects are larger after a day or more than at shorter intervals, where individual studies vary from reliable to null or reversed — related
• The testing effect is largest at a retention interval of 1–6 days (g = 0.82) and robust across all intervals — related
• Retrieval interval length may moderate the testing effect in mathematics: restricting to intervals over one day raises the effect to g = 0.378 (exploratory). — related
