Table 4.
Item Exposure and Item Bank Use for the DINA Model (Variable Length).
| Stopping criteria | Item selection | Test overlap | Overused (>0.2) | Underused (<0.02) |
|---|---|---|---|---|
| 0.7 | PWKL | 0.671 | 10 | 412 |
| SHTVOR | 0.033 | 0 | 73 | |
| DBS | 0.029 | 0 | 0 | |
| 0.8 | PWKL | 0.622 | 13 | 395 |
| SHTVOR | 0.037 | 0 | 54 | |
| DBS | 0.035 | 0 | 0 | |
| 0.9 | PWKL | 0.593 | 15 | 390 |
| SHTVOR | 0.045 | 0 | 25 | |
| DBS | 0.042 | 0 | 0 |
Note. DINA = deterministic input, noisy, and gate; PWKL = posterior-weighted Kullback–Leibler method; SHTVOR = Sympson–Hetter method, which comprises test overlap control, variable length, online update, and restricted maximum information; DBS = dynamic binary searching.
