认知诊断模型的属性作用机制： R_RUM、NIDA与DINA比较

he Monte Carlo simulation method was used here. Three experiments conditions were considered. The first one was the uncontrolled the mechanism of cognitive attributes of the R_RUM, NIDA and DINA model; the second one was the controlled mechanism of compensated cognitive attributes; and the third one was the controlled mechanism of both compensated and equal weighted cognitive attributes. The findings reflected: （1）The difference in attribute operation routine was the key difference among the three models, and was also the critical factor resulting in different cognitive diagnosis consequences among the models.（2）There was some kind of relationship among the models. When the compensated operation was controlled, the effect was in equal between the R_RUM and DINA model.（3）When the attribute weights were further controlled, the effects of the models were equivalent.（4）If there is no controlling on attribute operation routines, the corrected match ratios of R_RUM and NIDA models were similar.
