Subclaims¶

q2 i? The third environment differed from the first two, with fewer later saved ERDs (44, 32.8%), more episodes without a target-level revision, and lower early-stage incorporation; the environments were not designed as comparison conditions. → Sara Riazi and Pedram Rooshenas 2026

q2 · i? · design · r2

Observational deployment analysis across three ERD environments (Table 1 reports 44 later ERDs, 32.8%, in Environment 3 versus 58.0% and 56.4% elsewhere). The article attributes the pattern possibly to "several closely related relationships" requiring distinctions among direction, cardinality, and participation.

"The third environment showed a different pattern, with fewer later saved ERDs, more episodes without a target-level revision, and lower early-stage incorporation than the other two environments."

• Students mostly used the workflow as an early-stage scaffold, and 73.4% of target-level changes after early-stage exits incorporated the hidden target without explicit correction being disclosed — related
• In a classroom deployment, 71.1% of observed target-level ERD changes fully or partially incorporated the hidden diagnostic target, conditional on students making a relevant revision — related
