When using item response theory (IRT) models in |
|
educational and psychological measurement, it is standard |
|
practice to estimate the operating characteristics of |
|
test items from examinees' item responses alone. This is |
|
the final report of a project that employed Bayesian and |
|
empirical Bayesian methods to exploit additional |
|
information that is often available about test items |
|
(e.g., format, content, or cognitive processing |
|
requirements) or about examinees (e.g., educational |
|
background or demographic status). Although collateral |
|
information about examinees and items is rarely employed |
|
in IRT, it is straightforward to incorporate it using |
|
Bayesian and empirical Bayesian methods. Employing |
|
collateral information is mandatory to obtain correct |
|
Bayesian and empirical Bayesian inferences if it was used |
|
to assign items to examinees. Practical and theoretical |
|
results obtained in a series of six research reports are |
|
summarized. (Contains 3 tables and 12 references.) |
