Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q4 i0 The overall long-term (pre-to-retention) gain is not significantly greater following high CI (24.56 ± 4.4%) than low CI (21.9 ± 9.8%) practice (ES = −0.13, p = 0.18). → Achraf Ammar 2024

q4 · i0 · quant-synthesis · r3
Pooled Δ pre-retention comparison in the multilevel meta-analysis of 36 studies: high CI gained 24.56 ± 4.4% versus low CI 21.9 ± 9.8%, a non-significant difference (ES = −0.13, p = 0.18) with a negligible printed effect size.
"However, this difference was not large enough (ES = − 0.35) to produce an overall greater long-term gain following high (24.56 ± 4.4%), compared to low (21.9 ± 9.8%) CI (ES = − 0.13, p = 0.18)."
Discussion¶
Learner Variables¶
- Long-Term Memory — outcome: instruction changes it
Related Claims¶
- Low (blocked) and high (random/serial) contextual interference practice do not differ significantly in acute skill gains (Δ pre-post) in PE and sports contexts — related
- High CI practice shows a statistically significant but small advantage in Δ post-retention change favoring high CI — related
- Age moderates both CI effects and female proportion moderates the acute CI effect, while other tested variables do not — related
- Only 20% of pooled performance outcomes agree with the paradoxical contextual interference effects — related
