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? Between-agent variation was largest on knowledge-point coverage (CV=27.3%) and medical knowledge accuracy (CV=18.5%), smallest on role-play quality (CV=5.7%), and difficulty calibration was low across nearly all agents. → Zhang Hui 2026

Zhang Hui, Qu Lihui, Zheng Jianmin, Xiong Yi, Bai Hongbo, Ji Ruiying, Liu Guohui, Chen Wanling, Cheng Zirui, Chen Youbang, Yang Chun-tao. (2026). What Platform Scores Miss: Multidimensional Evaluation of AI Teaching Agents in Medical Education. JMIR Medical Education. https://doi.org/10.2196/96819

q2 · i? · design · r2

Rubric scoring of 167 dialogues by Claude Opus 4.8 across 8 agents; agent totals ranged 60.6-91.6. The article reports coefficients of variation per dimension, with "role-play quality was the most uniform dimension (CV=5.7%)".

"It was largest on the 2 knowledge-related dimensions, namely knowledge-point coverage (CV=27.3%) and medical knowledge accuracy (CV=18.5%), indicating that agents differed most in what and how accurately they taught. In contrast, role-play quality was the most uniform dimension (CV=5.7%)"
