该文通过对CAT测验信息量计算公式分析,给出了CAT较好的分层终止规则。实验数据表明,该分层终止规则能大大地提高考试的保密性和测验效率。
Based on test information formula analysis, a series of better Hierarchical Termination Rules of CAT with stratified strategy is proposed in the paper. The results of Monte Carlo study show that the proposed hierarchical termination rules can greatly improve elficiency and confidentiality of examination.
