CRAS (Complexity-Resources-Abstractness and Strategy) is a qualitative framework developed in the 1990s by researchers at UCLES (now Cambridge Assessment) to measure the demand of individual exam questions. The original intentions of the framework were to give an insight into the dimensions that contribute to 'item' (exam question) demand. It is, however, less clear about how these individual item characteristics interact if CRAS is used to try to measure the level of demand in a whole question paper or qualification.
In this seminar, researchers from Cambridge Assessment reported on an evaluation of the CRAS framework which has been used to gauge and compare the demands that are implicit to assessment items. After outlining the CRAS framework and describing its origins, they then reviewed the way that the framework has been applied in a variety of published studies before suggesting a set of recommendations and good practice for researchers who use the CRAS framework.
Our researchers also explained the KRG technique, and reviewed some published studies which have employed the technique to evaluate assessment demands, again suggesting recommendations and good practice for researchers who use this technique.
