Validation of Cognitive Sensitivity for Item Response Curves.

Tatsuoka, Kikumi K.

Journal of Educational Measurement, v24 n3 p233-45 Fall 1987

This study examined whether the item response curves from a two-parameter model reflected characteristics of the mathematics items, each of which required unique cognitive tasks. A computer program performed error analysis of test performance. Cognitive subtasks appeared to influence the slopes and difficulties of item response curves. (GDC)
