q2 i? The three peer feedback conditions differed significantly in structural complexity, with the PS-GenAI PF group highest and the PF group lowest. → Chang 2026

q2 · i? · causal · r2

Kruskal-Wallis H test over 12 groups (four per condition) in a 16-week teacher education course, comparing relative gains in argument structure across PF, GenAI-PF, and PS-GenAI-PF conditions. The test was significant ("H = 9.66, p = 0.008"), with PS-GenAI PF highest (Mean = 0.20); no standardised effect size is printed for this finding beyond the reported ε2.

"for the structural complexity, the results showed a significant difference between the three groups (H = 9.66, p = 0.008 < 0.05, ε2 = 0.17). The PS-GenAI PF group had the highest score on the structural complexity (Mean = 0.20, SD = 0.16)"
