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? The study's quantitative patterns support characterizing teacher feedback as an expert dynamic scaffold and AI-assisted peer feedback as a technology-mediated, socially collaborative scaffold, neither of which alone addresses the multidimensional ZPD. → Tang J 2026
Evidence¶
Tang J 2026¶
Tang J, Li P, Luo R (2026) Teacher feedback VS AI-assisted peer feedback in L2 writing: A quasi-experimental study in a Chinese University. PLoS One 21(6): e0345976. https://doi.org/10.1371/journal.pone.0345976
q2 · i? · causal · r1
The authors' sociocultural-theoretical interpretation of their quasi-experimental findings, framing teacher feedback as expert-provided dynamic scaffolding and AI-assisted peer feedback as "technology-mediated collaborative scaffolding" within Vygotsky's ZPD framework.
"this study confirms that teacher feedback and AI-assisted peer feedback are “heterogeneous scaffolds” with different natures and complementary advantages. No single mode can comprehensively address the multidimensional challenges of L2 writing ability development."
