Abstract

One important element in designing experimental tests is the selection of appropriate and adequate items. One way to calibrate items in a simple and elegant manner is to adopt the Rasch model. In our research project on modelling components of reading, the Rasch model is implemented as a sample-free item analysis procedure on the microcomputer. In this paper, the algorithmic implementation of the procedure is reported. In addition, a graphical approach to item analysis based on the Rasch model is presented.
