Subclaims¶

q2 i? Across three rounds of iterative design, original plan means rose from 58.2 to 67.6 to 76.6, and by the final round all five products were rated good or above. → Ren 2025 q2 i? Neither original nor revised lesson plans received any excellent grades (above 90) in any round. → Ren 2025 (2)

q2 · i? · causal · r1

Analysis of lesson plans from five groups across three iterative design cycles, scored with the Lesson Plan Scoring Rubric (Table 5): original means 58.2, 67.6, 76.6; revised means 74.6, 75.6, 79.4. In the first round no original design reached a good grade; "all 5 products were rated as good or above" by the last round.

"By the last round of design practice, all 5 products were rated as good or above."

q2 · i? · causal · r1

Descriptive analysis of the same five groups' scored plans across all rounds: despite steady improvement, "both the original and the revised manuscripts received no excellent grades", and the authors conclude high scores remain elusive, needing continued professional learning and long-term practice.

"However, both the original and the revised manuscripts received no excellent grades."
