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? Because the Winter 2026 deployment bundled LaTA autograding, a corrections workflow, and expanded TA office hours relative to Winter 2025, any exam-score gain should be attributed to the composite intervention. → Jesse A. Rodríguez 2026

q2 · i? · causal · r1
Methods statement for the quasi-experimental between-cohort comparison (Winter 2026 vs. Winter 2025, same instructor and exam structure, about two-thirds of items held identical). The article deliberately reports no inferential statistics on this comparison.
"Any exam-score gain should therefore be attributed to thecompositeintervention: autograding plus corrections plus expanded office hours."
