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? Among 250 error-positive episodes, 128 included a change to the targeted relationship or participation constraint, and 91 of those changes fully or partially incorporated the hidden diagnostic target (71.1% of observed changes, 36.4% of all error-positive episodes). → Sara Riazi and Pedram Rooshenas 2026

q2 · i? · design · r2
Trajectory analysis of 383 feedback episodes from 48 students in a mixed-level Database Systems course, comparing the ERD at feedback time with the first subsequently stored ERD. The article reports "128 (51.2%) included a change" and 91 full or partial incorporations, a behavioral alignment measure, not correctness.
"Among the 250 episodes with an identified error, 128 (51.2%) included a change to the targeted relationship or participation constraint. Ninety-one of these changes fully or partially incorporated the hidden diagnostic target."
Discussion¶
Related Claims¶
- 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
- The third ERD environment showed fewer later saved ERDs, more episodes without target-level revision, and lower early-stage incorporation than the other two environments — related
- Qualitative analysis found staged disclosure sometimes withheld inaccurate diagnostic details, but some errors still shaped student revisions — related
