Subclaims¶

q2 i? The PS-GenAI PF group scored significantly higher than the PF group on rebuttal data and warrant. → Chang 2026 q2 i? The PS-GenAI PF group scored significantly higher than both the PF group and the GenAI-PF group on addressing the opposing view. → 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 · r2

Kruskal-Wallis H test of structural-complexity gains across the three conditions in the same 12-group study. The rebuttal data and warrant element differed significantly ("H = 8.41, p = 0.015"), with pairwise PS-GenAI PF > PF, p = 0.016; no standardised effect size is printed in the pairwise sentence.

"there was a significant difference between the scores of the three groups on the rebuttal data and warrant (H = 8.41, p = 0.015 < 0.05, ε2 = 0.14), with the PS-GenAI PF group (Mean = 0.49, SD = 0.80) and the GenAI-PF group (Mean = 0.49, SD = 1.38) scored higher than the PF group"

q2 · i? · causal · r2

Pairwise comparison within the Kruskal-Wallis analysis of argument-quality gains. The PS-GenAI PF group exceeded both the GenAI-PF group (this quote) and the PF group (p = 0.038); no effect size is printed in this pairwise sentence.

"The PS-GenAI PF group (Mean = 0.25, SD = 0.25) had a significantly higher score of addressing the opposing view than the GenAI-PF group (Mean = 0.09, SD = 0.27), p = 0.015 < 0.05."

Discussion¶

Related Claims¶

• Argument quality gains favored the PS-GenAI-PF group over the PF group, while elaboration gains favored the GenAI-PF group — a broader claim this one bears on
• GenAI-supported peer feedback groups achieved higher structural complexity of argumentation artifacts than peer-feedback-only groups — related
• GenAI-supported peer feedback groups produced more suggestions and explanations and less positive affective feedback than the PF group — related
• Most individual argument structure and quality dimensions showed no significant differences across the three peer feedback conditions — reports the opposite
• Direct GenAI-supported feedback improves immediate argument-quality gain over peer feedback, while reflective and hybrid designs outperform direct GenAI feedback — related
• Instructors and LLMs distribute feedback similarly across the five argumentative goals, with Claim receiving the most feedback from both — related
• Epistemic network analysis linked the PS-GenAI-PF group to negative emotions and higher-order feedback content associations — related
