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.
q3 i2 Subgroup analysis shows VR interventions lasting at least 1 day had moderately-to-large effects on scores (SMD = 0.71) versus a small effect for interventions under 1 day (SMD = 0.35). → Zhao Jingjie 2020

q3 · i2 · quant-synthesis · r2
Subgroup analysis by intervention duration across the 15 trials, reported in Table 2. The review reports "SMD = 0.71; 95% CI 0.42–1.10" for at least 1 day versus "SMD = 0.35; 95% CI 0.18–0.52" for under 1 day.
"VR interventions for at least 1 day had moderately-to-large effects on scores (SMD = 0.71; 95% CI 0.42–1.10, p < 0.001), whereas those which were < 1 day had only a small effect (SMD = 0.35; 95% CI 0.18–0.52, p < 0.001)"
Discussion¶
Related Claims¶
- TBL effects on theoretical knowledge and practical skills are larger in interventions lasting more than 4 weeks — related
- Short-duration (<24 weeks) interventions positively impact reading comprehension (SMD = 0.24) — related
- Program intensity is a significant moderator: high-duration gloss interventions yield larger effects (ES = 1.48) than low-duration ones (ES = 0.57) — related
- Interventions lasting ≥24 weeks show larger effects on mathematics and overall academic achievement than shorter interventions — related
- Intervention duration significantly moderates Gen-AI's effect on HOT, with the strongest effects at 8–16 weeks (ES = 0.759) and weaker effects for shorter (0.494) and longer (0.372) interventions — related
- Meta-regression finds no significant moderators of VR's effect on anatomy examination scores — related
