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? On the untouched held-out split, Baseline + Reflective increased final-success Macro-F1 from 0.725 to 0.743 and changed the Brier score from 0.177 to 0.175; the article states these differences are small and not educationally important. → Wang S and Zhao J 2026 q2 i? Across repeated and calendar-window sensitivity analyses the reflective-feature Macro-F1 difference was negligible (mean difference 0.006 in the repeated analysis; between –0.001 and 0.002 across 30%–50% windows). → Wang S and Zhao J 2026 (2)

Wang S and Zhao J (2026) Reflective AI use and student engagement in AI-supported programming: technology acceptance, programming self-efficacy, and behavioral trace evidence. Front. Psychol. 17:1929887. https://doi.org/10.3389/fpsyg.2026.1929887

q2 · i? · associational · r2

Held-out comparison on the DTA programming-log dataset (N = 1,423; early-window N = 1,122) using a locked pipeline with a stratified 70%/30% split. The article reports "For final_success_all_11, Baseline + Reflective increased Macro-F1 from 0.725 to 0.743"; the Full Model reached the highest ROC-AUC (0.808) but did not outperform all configurations across all metrics.

"For final_success_all_11, Baseline + Reflective increased Macro-F1 from 0.725 to 0.743 and changed the Brier score from 0.177 to 0.175. These absolute differences are small and are not evidence of educationally important improvement."

q2 · i? · associational · r2

Repeated five-fold cross-validation and 30%–50% calendar-window sensitivity analyses with locked learner specifications. The article reports "The original repeated analysis showed a mean difference of 0.006" and that the reflective-feature Macro-F1 difference remains between –0.001 and 0.002 as the window expands, so the held-out 0.018 difference should not be generalized as a stable practical gain.
