Applying the Rasch Growth Model for the Evaluation of Achievement Trajectories

Applying the Rasch Growth Model for the Evaluation of Achievement Trajectories Considerable interest lies in the growth in educational achievement that occurs over the course of a child’s schooling. This paper demonstrates a simple but effective approach for the comparison of growth rates, drawing on a method first proposed some 80 years ago and applying it to data from the Australian National Assessment Program. The methodology involves the derivation of a ‘meta-metre’ – a quantitative mode of variation in growth – which permits comparison between groups defined by time-invariant characteristics. Emphasis is placed upon the novel characteristics of the method and the valuable information it can provide. Unlike complex modelling procedures, the approach provides a parsimonious model of growth suited to comparisons between groups. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australian Journal of Education SAGE

Abstract

Considerable interest lies in the growth in educational achievement that occurs over the course of a child’s schooling. This paper demonstrates a simple but effective approach for the comparison of growth rates, drawing on a method first proposed some 80 years ago and applying it to data from the Australian National Assessment Program. The methodology involves the derivation of a ‘meta-metre’ – a quantitative mode of variation in growth – which permits comparison between groups defined by time-invariant characteristics. Emphasis is placed upon the novel characteristics of the method and the valuable information it can provide. Unlike complex modelling procedures, the approach provides a parsimonious model of growth suited to comparisons between groups.
