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.
q2 i? Simulation quality (average Con2 score) shows a clear positive correlation with student cognitive ability scores. → Tao Wu 2025
Evidence¶
Tao Wu 2025¶
Tao Wu, Jingyuan Chen, Wang Lin, Mengze Li, Yumeng Zhu, Ang Li, Kun Kuang, Fei Wu. (2025). Embracing Imperfection: Simulating Students with Diverse Cognitive Levels Using LLM-based Agents. https://arxiv.org/abs/2505.19997 doi:10.48550/arxiv.2505.19997
q2 · i? · design · r2
Correlational analysis in Section 5.3 relating average Con2 score to student cognitive ability scores (Figure 5); no correlation coefficient is printed. The article notes generating a fully correct solution is easier than simulating a specific student's realistic mistakes.
"The figure reveals a clear positive correlation between simulation quality and cognitive ability, indicating that simulating students with higher cognitive abilities is relatively easier."
