- 摘要:
- 根据PETS考试的特点，结合计算机自适应序列测试（CAST）的优势，该研究提出并设计了PETS-CAST测试。为了检验PETS-CAST测试系统的性能，该研究利用PETS试题的真实难度参数和模拟的考生能力参数生成相应的原始得分矩阵，并根据路径规则实现适应性的模块选择。研究结果表明，PETS-CAST所设计的路径能够满足不同能力水平考生的要求，且各条路径的测量精度均能够达到CAST考试的要求。曝光率方面的研究则说明，PETS-CAST应该在设计题池时充分考虑试题模块在数量方面的配置。该模拟研究为PETS-CAST的具体实施在理论和实践层面做了一些有益的尝试。
- Abstract:
- Based on consideration of the PETS characteristics and its future development，the researchers start with design of PETS-CAST.This simulation study is conducted to validate the performance of the PETS-CAST system.Real difficulty parameters of PETS items and the simulated ability parameters of the candidates are used to generate the original score matrix and the item modules are delivered to the candidates following the adaptive procedures set according to the path rules.Results show that the suggested paths are suitable for PETS candidates and the measurement accuracy for each of the paths is high enough to meet the requirements of the CAST.The exposure rate of each item module tells us the number of modules that should be ready for the candidates to choose from.This simulation study provides a sound basis for the implementation of PETS-CAST.
