计算机化自适应测试：实施问题
Computerized adaptive testing: implementation issues
摘要：
学生性能评估是教学研究中发展最快的领域之一。基于计算机的测试系统越来越多地被大学采用。然而，这样一个系统及其底层题库的实现和维护对于一个没有经验的教师来说是一个挑战。因此，本文讨论了计算机自适应测试（CAT）系统相比，基于计算机的测试系统的优点和缺点。此外，几个项目选择策略进行了比较，以克服项目曝光的缺点，这样的系统。本文还介绍了我们的CAT系统沿其发展步骤。此外，本文还提出了一种基于自评系统数据的题目难度估计方法。
英文摘要：
One of the fastest evolving field among teaching and learning research is students' performance evaluation. Computer based testing systems are increasingly adopted by universities. However, the implementation and maintenance of such a system and its underlying item bank is a challenge for an inexperienced tutor. Therefore, this paper discusses the advantages and disadvantages of Computer Adaptive Test (CAT) systems compared to Computer Based Test systems. Furthermore, a few item selection strategies are compared in order to overcome the item exposure drawback of such systems. The paper also presents our CAT system along its development steps. Besides, an item difficulty estimation technique is presented based on data taken from our self-assessment system.
