提出3种变长CD-CAT终止规则,在DINA模型、4种属性层级结构下,采用ED选题策略,讨论提出的3种方法与常用CD-CAT终止规则在7个评价指标上的优劣.研究结果显示:新的3种方法较常用终止规则有其自身优势.
Three new variable-length termination rules in cognitive diagnosis computerized adaptive testing is proposed. Results of the new methods with pre-existing methods were compared under seven evaluation indexes,using the deterministic inputs,noisy "and"gate( DINA) model,four kinds of attribute hierarchies and the expected discrimination method( ED). Date showed that the new three variable-length termination rules have their own advantages.
