经典测试理论的改进策略及其实证研究

Study on the Improvement Strategy for Classical Test Theory

分析了经典测试理论作教学评价领域使用较为广泛的一种测试理论,具有易被人理解和接受、概念直观、计算简便、适用性广的优点的同时也存在着不足,主要是其评价严重依赖于测试样本。在分析经典测试理论优缺点的基础上,提出了一种改进的策略,并通过相关具体实例和计算机系统演绎的方式验证了改进策略的正确性、有效性,以期为考试制度的改革提供有意义的借鉴。

Classical test theory is widely used in the teaching evaluation field because of its advantages, such as easily understanding, intuitive concepts, simple calculating, wide range of applications. But it also has some disadvantages, and most of these is that evaluation relies heavily on the test samples. Based on the advantages and disadvantages of the classical test theory, it put forward an improved strategyin this pa- per, and its correctness and validity were verified by related specific example and deductive way of the computer system, so as to expect it can play a role in the reform of the examination system.
