Subclaims¶

q2 i? During supported assignments, observed writing means were highest in the open collaboration condition and increased across assignments in all conditions. → Chen X 2026 q2 i? At the Week 8 independent no-AI assessment, the bounded-support condition had the highest observed means on all four outcomes. → Chen X 2026

q2 · i? · causal · r2

Class-clustered quasi-experimental comparison of three conditions across three intervention assignments in six intact classes (168 students). The article reports that supported-writing means "were highest in open collaboration" on aggregated supported writing quality (open M = 4.02, bounded 3.83, no-AI 3.57).

"Observed supported-writing means increased across assignments in all conditions and were highest in open collaboration (Table5)."
