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? Differences in average content-description scores between erroneous and non-erroneous student images persist after standardized digital redrawing, across four representative VLMs. → Li Lucy 2026

Li Lucy, Albert Zhang, Nathan Anderson, Ryan Knight, Kyle Lo. (2026). The Aftermath of DrawEduMath: Vision Language Models Underperform with Struggling Students and Misdiagnose Errors. https://arxiv.org/abs/2603.00925 doi:10.48550/arxiv.2603.00925

q2 · i? · causal · r1

Experiment in which the lead author digitally redrew one erroneous and one correct response per problem, yielding 336 images; Table 2 prints per-model score differences on original versus redrawn images, e.g. Gemini 2.5 Pro -0.089*** to -0.096***, with significance markers but no standardized effect size.

"Differences in average scores on content description QA between erroneous and non-erroneous student images persist after redrawing. ** p <0.01 , ***p<0.001."
