New Item Selection Criteria of Computerized Adaptive Testing with Exposure-Control Factor: New Item Selection Criteria of Computerized Adaptive Testing with Exposure-Control Factor
摘要: 在计算机化自适应测验(CAT)的研究中, 制定既高效又安全的选题策略是一个追求目标。用极大项目信息量准则(MIC)选题使得测验效率高、能力估计准确, 缺点是项目调用很不均匀, 影响考试的安全; 按a分层法通过控制试题曝光率以提高考试的安全性, 但该方法可能会使测验效率略有下降, 且该方法在各层内部无法实现对区分度的调整。本文针对上述两种选题策略的优缺点, 对0-1评分下的CAT, 通过引入曝光因子、分阶段自动调整区分度的影响以及提高选题准确性等手段, 对MIC和a-STR进行改进, 引入了两类新的选题策略。计算机模拟实验显示, 新的选题方法效果比较理想
