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 i? Robust one-way ANOVAs on the six raw NASA-TLX subscales revealed no statistically significant difference across conditions after p-value adjustment. → Luiz Rodrigues 2026

q3 · i? · causal · r2

Teachers' perceived workload was measured with the raw NASA-TLX (0–10 per subscale) at the end of the intervention; the article reports that "Table 5 reveals no statistically significant difference based on adjusted p-values" across the three conditions.

"Descriptively, the Experimental condition yielded the lowest ratings for Mental Demand, Physical Demand, Performance, and Effort. Its Temporal Demand rating was comparable to that of the Training condition, and both were lower than the Control one. Only for Frustration did the Experimental condition rate higher than the Training one, although still lower than the Control one. However, Table 5 reveals no statistically significant difference based on adjusted p-values."
