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 Students in the LLM condition reported significantly lower germane cognitive load than students in the web search condition, adjusted for prior knowledge (η² = 0.27), the strongest difference among the three load facets. → Matthias Stadler 2024

Matthias Stadler, Maria Bannert, Michael Sailer. (2024). Cognitive ease at a cost: LLMs reduce mental effort but compromise depth in student scientific inquiry. Computers in Human Behavior. https://doi.org/10.1016/j.chb.2024.108386
q3 · i3 · causal · r2
ANCOVA in the randomized experiment (n=91) controlling for prior knowledge. LLM group mean GCL was 3.14 (SD 1.53) versus 4.79 (SD 1.18) for web search, with "33.06 <0.001 0.27", i.e., η² = 0.27, a large effect. The text notes "The strongest difference was found for GCL, the smallestforECL."
"H1.3-GCL 4.79(1.18) 3.14(1.53) 33.06 <0.001 0.27"
