q4 i? In subset 2, the number of exposures of an item during retrieval practice explains inconsistencies between studies: the more learners are tested, the more beneficial the expanding schedule is compared with the uniform one. → Latimier 2021

q4 · i? · quant-synthesis · r2

Moderator meta-regression on subset 2 (54 effect sizes comparing expanding and uniform schedules). The review reports that "the number of exposures of an item during retrieval practice explains inconsistencies between studies", with more testing favouring the expanding schedule.

"Moderator analyses on this subset showed that the number of exposures of an item during retrieval practice explains inconsistencies between studies: the more learners are tested, the more beneficial the expanding schedule is compared with the uniform one."

Discussion¶

Related Claims¶

• Total retrieval spacing improved one-week vocabulary recall while relative schedules were not distinguished — the general claim this finding bears on, with the studies behind it
• Expanding and uniform spacing schedules of retrieval practice do not differ significantly in final retention (g = 0.034) — related
• Spaced Retrieval Improves Retention — related
• Uniform two-week spacing between distillations yielded the greatest benefit among the tested schedules, ranking Standard, Mixed, Frontloaded, then Baseline — related
• Expanding retrieval schedules have not shown consistent advantages over equally spaced or contracting schedules matched on total spacing — related
