A Feasibility Study on Development of A Computerized Adaptive Testing System for Students with Disabilities to Take the Tests of National Center for University Entrance Examinations

这是开发一种计算机化自适应考试（CAT）系统的可行性研究，该系统可以用比普通纸笔考试短1/2或2/3的时间来评估残疾学生的成绩，并在全国大学入学考试中心考试中采用。虽然根据我的实验研究结果，残疾人考生在国家中心的考试中需要比现在更长时间的限制，但很难再延长。因为，如果延长考试时限，将成为残疾学生和国家考试中心管理部门难以承受的负担。因此，本研究针对残疾学生的不同类型和程度，对CAT的用户界面设计进行了优化研究，以开发一款适合残疾学生的CAT。利用国家高考中心储存了二十多年的大量题库，建立了计算机辅助考试题库。为了彻底改善残疾学生的测试方法，我想在下一个项目中完成这个CAT并对其进行评估。

This is a feasibility study to develop a computerized adaptive testing (CAT) system by which the achievement of students with disabilities can be assessed with time limit 1/2 or 2/3 as short as that of ordinary paper and pencil tests, and to adopt it in the Test of National Center for University Entrance Examinations. It is difficult to extend the time limit for test-takers with disabilities in the Tests of National Center still longer, although they needed longer time limit than that in present according to the results of my experimental studies. Because it would become an intolerable burden on students with disabilities as well as administrations of the Tests of National Center if the time limit was extended longer than that in present.In this study, therefore, designs on user interfaces of CAT were studied optimal to each kind and extent of disabilities to develop a CAT for students with disabilities. An item pool of CAT was also developed by using a large amount of test items stored in the National Center for University Entrance Examinations for over twenty years.To improve testing methods for students with disabilities drastically, I would like to complete this CAT and made its assessment in a next project.
