Use of Restricted Item Response Models for Examining Item Difficulty Ordering and Slope Uniformity.

Lane, Suzanne

Journal of Educational Measurement, v28 n4 p295-309 Win 1991

The use of restricted item response models to test hypotheses regarding item difficulty ordering and slope uniformity was demonstrated in a study in which 597 algebra students were asked to solve word problems reflecting various types of cognitive processing. Benefits and limitations of the procedures are discussed. (SLD)
