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 i3 The experimental group reported significantly lower cognitive load than the control group on all six dimensions, with d ranging from 1.12 to 1.80; learning clarity showed the largest difference (d = 1.80). → Feng Z and Huang K 2026
Evidence¶
Feng Z and Huang K 2026¶
Feng Z and Huang K (2026) Bayesian cognitive diagnosis optimizes personalized learning paths via mediation of cognitive load and Hidden Markov Model state transitions. Front. Psychol. 17:1879982. https://doi.org/10.3389/fpsyg.2026.1879982
q3 · i3 · causal · r2
Between-group comparison on an adapted six-dimension NASA-TLX (mental demand, time pressure, effort, frustration, attention, learning clarity; higher scores indicate greater load) in the 120-participant randomized experiment, with "d ranging from 1.12 to 1.80".
"The experimental group exhibited significantly lower cognitive load on all six dimensions, with effect sizes all at a large level (d ranging from 1.12 to 1.80). Among them, the learning clarity dimension showed the largest between-group difference (d = 1.80)"

- AI multimodal feedback is rated higher than educator feedback on specificity, clarity, simplicity, motivation, satisfaction, and lower mental effort, with comparable correctness, trust, and acceptance — related
- Teacher perceived workload did not differ significantly across conditions on any NASA-TLX subscale, though the experimental condition was descriptively lower on most subscales — reports the opposite
