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? Compared with the mean pre-course score baseline, the Concept and Scales methods achieved lower prediction error across all dimensions and both metrics, e.g., motivation RMSE 9.31 (Concept) and 17.41 (Scales) versus baseline 11.18. → Jianxiao Jiang 2025

q2 · i? · design · r2
A case study simulated 42 stratified-sampled student agents on the first module of an MAIC course, comparing predicted post-module questionnaire scores to real students' using RMSE and MAE. The article reports Concept was best on all dimensions except Technology Acceptance, best predicted by Scales; no effect sizes are printed.
"Compared to the Mean baseline method, our approaches outperformed across all dimensions and both error estimation metrics."
