Extract
The Rasch measurement principles espoused in the Bond & Fox (2001) volume reviewed elsewhere in this journal are routinely adopted by Australia's major educational measurement projects (e.g., by Australian Council for Educational Research, Educational Testing Centre). Yet those ideas are yet to have their full impact in smaller research projects in educational and developmental psychology. A number of quantitative analytical techniques used in our disciplines are able to help us to draw conclusions like “Betty is better than or more developed than Bob”, but Rasch measurement is uniquely placed to help us conclude that “Betty is this much better than or more developed than Bob.” In educational and psychological statistics, we regularly presume the “interval” nature of our research data, but only the Rasch model sets about to ensure that the units of measurement maintain their unit value across the whole achievement or development scale.
