Problems with Publishing
-
The static pool
-
Restricts content
-
Restricts psychometrics
-
Restricts corrections
-
Structures item exposure
-
The publication process
-
Creates logistic problems
-
Slows response to new content
-
Item filtration – An alternative to test publishing
-
Realtime test creation
-
Begins with entire item pool
-
Removes items until one item is chosen to administer
Research Questions
-
Since filtering adds constraints, what is the psychometric impact?
-
Can we use filtering to control item drift?
-
How does filtering interact with item selection?
