基于项目反应理论自适应考试系统的设计与应用

在个性化教育中,传统的考试形式正面临着越来越多的问题,统一的试题内容并不适用于各个层次的学生,考试成绩无法准确衡量学生的能力.个性化学习系统中的自适应考试系统(PLCAT),部分地解决了传统考试形式所面临的问题.PLCAT考试系统是基于项目反应理论的Web自适应考试系统,学生可以随时随地使用PLCAT系统进行测试,系统能够根据学生的能力自动选择适合学生的试题,并在考试结束时给出个性化的评价.实践证明,PLCAT系统可以提高考试效率和提高对学生评价的精度,更重要的是,它为个性化教育提供了一种更加有效的测验途径,也为贯彻现代化教育理念,提高学生自主学习能力、创新能力提供了一种新思路.

Design and Application of Computerized Adaptive Testing System Based on Item Response Theory

In personalized education,the traditional examination forms are facing increasing problems,a unified examing paper do not suitable for all students with different levels,therefore,testing score can not measure students abilities accurately.Personalized Learning of Computerized Adaptive Testing System（PLCAT）,partially solve some problems of traditional examination.PLCAT testing system is a Web CAT system based on Item Response Theory（IRT）.Students can be tested anytime and anywhere by PLCAT.PLCAT system can select questions automatically for students according to their ability and conclude a personalized evaluation for them when examination finish.Practise shows that PLCAT system may improve testing efficiency and students evaluating accuracy.What＇s more important is it provides a more effective testing way for personalized education.Meanwhile provides a new thought for implementing modern education concepts,increasing self-learning ability,and innovation ability.
