- Summary:
-
The project was focused on large scale assessments which involve comparisons of the performance of students across time. For many reasons, identical items cannot be administered to every student on every occasion. Nevertheless, the items must operate invariantly across groups. The Rasch models, which are used in Australia for scaling items, provide a powerful means for checking for such invariance. This project brought together the basic research of Professor Andrich and his colleagues to study, apply and document ways in which violations of Rasch models and different data collection formats are reflected as changes of scale. The research was relevant in the assessment of all areas of assessment including writing. The reason that the topic is significant for national assessment is that differences in scale can make the percentage of students reported as achieving the benchmark misleading. The project focused on how differences in scale might be controlled both statistically and empirically. In the case of writing, the research indicates that marking keys and formats need to be modified in order to control the effects on the scale rather simply statistically.
