Subclaims¶

q2 i? Overall argument quality differed significantly across conditions, with the PS-GenAI PF group highest. → Chang 2026 q2 i? Elaboration was significantly higher in the GenAI-PF group than in the PF group. → Chang 2026 (2)

Evidence¶

Chang 2026¶

Chang, Y., Liu, Q., Lu, Y. & Miao, E. (2026). Leveraging generative AI to facilitate peer feedback in collaborative argumentation learning. International Journal of Educational Technology in Higher Education. https://doi.org/10.1186/s41239-026-00586-w

q2 · i? · causal · r1

Kruskal-Wallis H test of relative argument-quality gains (seven 5-point rubric dimensions) across the three conditions. The omnibus test was significant ("H = 9.69, p = 0.008"), with pairwise PS-GenAI PF > PF, p = 0.007; no standardised effect size is printed in the pairwise sentence.

"For argument quality, there was a significant difference between the three groups (H = 9.69, p = 0.008 < 0.05, ε2 = 0.17), with the PS-GenAI PF group scored the highest for argument quality (Mean = 0.16, SD = 0.10)"

q2 · i? · causal · r2

Pairwise comparison within the same Kruskal-Wallis analysis of argument-quality dimension gains. Elaboration favored the GenAI-PF group over the PF group; the PS-GenAI PF group did not significantly exceed the PF group on this dimension, and no effect size is printed for the pairwise contrast.

"Pairwise comparisons showed that elaboration was significantly higher in the GenAI-PF group (Mean = 0.32, SD = 0.32) than in the PF group (Mean = 0.08, SD = 0.18), p = 0.026 < 0.05."

Discussion¶

Related Claims¶

• GenAI-supported peer feedback groups achieved higher structural complexity of argumentation artifacts than peer-feedback-only groups — related
• The PS-GenAI-PF group outperformed the PF group on rebuttal data and warrant and on addressing the opposing view — a narrower finding that bears on this claim
• Most individual argument structure and quality dimensions showed no significant differences across the three peer feedback conditions — related
• GenAI-supported peer feedback groups produced more suggestions and explanations and less positive affective feedback than the PF group — related
• Direct GenAI-supported feedback improves immediate argument-quality gain over peer feedback, while reflective and hybrid designs outperform direct GenAI feedback — related
