先看结论

该不该做、置信度多高、最关键的证据边界在哪。

建议决策 全面采用 置信度 · 高

延迟保持与迁移这两个主要结果上都有直接且一致的证据（多项随机对照与元分析，直接性记为 2），实施成本低、风险可控，因此支持在课程内采用。最佳间隔安排与程序设计课程现场证据的厚度仍是记录在案的不确定性，纳入采用后的持续监测，而不是阻止采用的理由。

最强支持结论

间隔检索练习在延迟保持上稳定优于集中复习，多项随机对照与元分析结论一致。

关键不确定性 / 反例

程序设计课程内的直接现场证据少于心理学实验室证据，最佳间隔设计尚未确定。

主要风险

练习设计不当可能增加认知负荷，且收益幅度受材料难度与反馈方式调节。

下一步

在入门编程课内采用每周固定短时闭卷检索练习，并以统一延迟后测持续验收：若延迟后测低于基线或练习完成率持续低于 60%，回退到试点状态复核。

结果分离 · 任务表现 ≠ 学习效果

将不同结果类型分开裁决，避免把训练时更快、更高分直接等同于真正学会。

Expand full explanation

Delayed retention and transfer — the two primary outcomes — carry direct and consistent evidence (randomised trials and meta-analyses at directness 2), with low implementation cost and little risk, so course-level adoption is supported. The optimal spacing schedule and the thin classroom evidence from programming courses remain recorded uncertainties to monitor after adoption rather than reasons to withhold it.

Strongest supported conclusion

Spaced retrieval practice consistently beats concentrated review on delayed retention across randomised trials and meta-analyses.

Key uncertainty / contradiction

Direct classroom evidence from programming courses is thinner than the psychology-lab evidence, and the optimal spacing schedule is unresolved.

Main risk

Poorly designed practice can add cognitive load, and the size of the benefit depends on material difficulty and feedback design.

Next action

Adopt weekly short closed-book retrieval practice inside the introductory programming course, verified by a common delayed post-test;…

Expand full explanation

Adopt weekly short closed-book retrieval practice inside the introductory programming course, verified by a common delayed post-test; fall back to pilot status for review if delayed retention drops below baseline or practice completion stays under 60%.

Evidence / sources · 6 / 7

Task performance ≠ learning

Only informative outcome separation; positive, negative and null effects use effect_direction.

Outcome Separation · Task performance ≠ learning

Outcomes are adjudicated separately so faster training performance is not silently treated as evidence of learning.

Effect direction comes from evidence.effect_direction; supporting a claim does not imply a positive outcome.

Learning / retention / transfer

  • RetentionPositive effect 4Null effect 1
  • TransferPositive effect 1

Evidence tribunal

Supported, uncertain, contradicted and missing evidence stay separated instead of flattened into long prose.

Decision: Adopt · Confidence: High

Can claim

3

  • Spaced retrieval practice reliably outperforms concentrated review on delayed retention.

  • Covert and overt retrieval produce comparable benefits, so the format is flexible.

  • Practising more retrieval routes improves transfer, so the value is not limited to memorisation.

Cannot yet claim

2

  • Direct classroom evidence from programming courses is thinner than the lab evidence [no direct evidence].

  • Benefit size depends on material difficulty and feedback design; the optimal spacing is unsettled.

Contradicted claims

0
  • No data.

Missing evidence

2

  • Randomised field studies inside programming courses

  • Direct comparisons of different spacing schedules

Evidence to action

Applicability, guardrails, stop conditions and evaluation form one executable path.

Evidence

Spaced retrieval practice reliably outperforms concentrated review on delayed retention.

Applicability

Introductory programming courses with fixed contact hours where weekly short practice can be scheduled reliably

Decision

Adopt

Guardrails

No AI tools in this pilot; practice is closed-book retrieval

Stop conditions

delayed post-test below baseline; completion stays under 60%
