q3 · i? · causal · r2

Between-group comparison of writing quality gain in the 2×2 experiment (120 undergraduates, four conditions, T1–T3). Descriptive means show the ordering; the article reports the combined group's "strongest descriptive advantage in improving writing quality". No effect size value is printed for this contrast.

"Across the three rounds, the combined group gained approximately 8 points, the FRAC group approximately 6 points, the APCA group approximately 4.5 to 5 points, and the regular AI group approximately 3 points."

Discussion¶

Learner Variables¶

• Writing Skills — outcome: instruction changes it

Related Claims¶

• FRAC and the combined intervention shifted revision toward deeper levels, with deep revision (L3+L4) rising from 25% in the regular AI group to 55% in the combined group — related
• FRAC and combined intervention advantages transferred to a new writing task and were retained after AI support was withdrawn — possibly the same claim (merge candidate)
• All three intervention groups converted AI feedback into effective revisions more successfully than regular AI use, with the combined group highest in effective adoption rate — related
• In one 2×2 experiment with 120 undergraduates, an Assessment-Performance Calibration Activity (APCA) gave the most accurate self-assessment and least overconfidence, and adding a feedback-literacy script did not improve calibration further — related
• The decisive empirical test of AI-augmented instruction frameworks is whether students retain representational competence when AI support is withdrawn — a broader claim this one bears on
