自适应英语测试系统的效率分析与进度验证

Efficiency analysis and schedule verification of adaptive english testing system

针对计算机自适应语言测试系统(CALT)应用在语言测试领域效果并不理想的现状,在英语题库的基础上研究了一个计算机自适应英语测试系统,并采用“评估使用论证”(Assessment Use Argument,简称AUA)对该测试系统进行效率分析。该方法用于评估CALT的程序,并在AUA框架内检验了CALT的有效性问题。针对CALT运行效度验证问题,采用了数据分析方法SPSS对系统进行配对T检验,并进行验证性因素分析,展开多群组SEM模型的分析,对CALT进行了较为系统的效度验证。该方法在计算机语言测试领域,对相关理论和实践均具有重要意义。

Based on the fact that the application of computer adaptive language testing system(CALT)in the language testing is not ideal,this paper studies a computer adaptive English Testing System based on the English question bank,and analyzes the efficiency of the testing system by using“assessment use argument”(AUA).This method is used to evaluate the procedure of CALT,and the effectiveness of CALT is tested in the framework of AUA.In order to verify the operational validity of CALT,SPSS is used to conduct paired t test,confirmatory factor analysis and multi group SEM model analysis.In the field of computer language testing,this method is of great significance to related theory and practice.
