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? When states were fully randomized and ITAP run 20 times with a cleared solution space between iterations, 99.3% (5840/5880) of states generated complete paths to solution. → Kelly Rivers & Kenneth R. Koedinger 2015

Advanced robustness test using the same 15-student dataset with states fully randomized in order and student traces split into individual states. The article reports "99.3 % (5840/5880)" complete paths, with almost all broken paths again from onlyTwoTrue (93.5% success there).
"We ran ITAP 20 times with randomized-order data sets, clearing the solution space in between each iteration. 99.3 % (5840/5880) of the states were able to generate complete paths to solution."
Discussion¶
Related Claims¶
- ITAP generated a full token-edit hint chain to a correct solution for 98.3% of semantically incorrect student states in submission order — related
- ITAP's average hint chain length (5.62 token edits) is shorter than the token length of the teacher solution (8.27), suggesting personalized paths — related
- ITAP's hint generation improves as solution data accumulates over time, supporting its self-improving design — related
- Smaller local LLMs show a minor position bias toward option ordering and partially guessing-like error variation, but accuracy remains relatively stable across permutations and repeated sampling runs — related
- Canonical states shorten hint chains on average (6.00 vs 7.61 edits), though abstract chains were longer for some problems — related
