Educational Measurement: Issues and Practice, v20 n2 p15-25 Sum 2001
Compared four mapping item methods using data from the physical science test of the National Assessment of Educational Progress and studied the opinions of science content area experts about the difficulty of the items through a survey completed by 148 science teachers or scientists. Results of model-based mapping methods were more concordant with experts' opinions about difficulty than those from empirical mapping methods. (SLD)
