Abstract:

Before then, no validity index can be used for evaluating the item ordering structure for cognition diagnosis. In this study, based on the Q-matrix theory, an ideal item ordering structure without slip and guess for an efficient test is proposed by using the set containing relation operation. It can be viewed as a criterion of the item ordering structure for a given test. Furthermore, a novel criterion-related validity index for evaluating the item ordering structure of any item ordering algorithm is proposed, it is more useful for cognition diagnosis.
