【摘要】：计算机自适应测验因其便利以及有效减少题目的曝光率而受到广大研究者和应用者的欢迎,CAT测验主要包括四大组成部分:题库建设、题目筛选,能力估计和终止条件。使用CADATS软件可实施基于CTT、IRT的计算机测验以及基于IRT的计算机自适应测验。但由于计算机自适应测验必须采取一定技术将纸质测验转换成计算机呈现的测验形式,需要测验操作专业人员具备一定的计算机编程能力。CADATS系统要求将纸质测验的jpg或swf图片形式在计算机上呈现,需要通过Flash软件对纸质测验进行再编制,并运用Action Script语言实现测验与CADATS的通讯联系,具备一定的复杂性。本研究运用Flash软件对纸质测验进行再编制,并采用项目反应理论当中的Rasch模型来进行计算机自适应测验,这是运用CADATS系统进行的一次中学英语学科的计算机自适应测验的实践研究,该研究可以有效促进我国基础教育领域计算机自适应测验的运用。计算机自适应测验要求先完成项目参数估计,本研究通过Bilog软件对某市高三英语模拟考试的题目做了难度的分析,剔除不合适的题目,将剩余题目放入CADATS中进行计算机自适应测验设计。从某大学选取60名被试做该CAT测验,对测验结果进行分析,研究结果表明,CADATS软件在题库管理、计算机自适应测验的实施、数据后期处理以及管理维护均具有较强的实用功能。
[Abstract]:Because of its convenience and effective reduction of topic exposure, computer adaptive testing has been welcomed by many researchers and applications. The cat test consists of four main components: construction of question bank, topic screening. Ability estimation and termination condition. Using CADATS software, we can implement computer test based on CTT / IRT and computer adaptive test based on IRT. But because computer adaptive test must adopt certain technique to convert paper test into calculation. The form of the test presented by the computer, It is necessary for the test operator to have certain computer programming ability. The CADATS system requires that the jpg or swf pictures of the paper test be presented on the computer, and that the paper test be recompiled through the Flash software. Using Action Script language to realize the communication between the test and CADATS, this study uses the Flash software to recompile the paper test, and adopts the Rasch model in the item response theory to carry on the computer adaptive test. This is a practical study of a computer adaptive test for English subjects in middle schools using the CADATS system. This research can effectively promote the application of computer adaptive testing in the field of basic education in China. In this study, the Bilog software was used to analyze the difficulty of the English simulation test of Senior three in a certain city, and the unsuitable questions were eliminated, and the remaining questions were put into the CADATS to design the computer adaptive test. 60 subjects were selected from a university to do the CAT test. The analysis of test results shows that CADATS software has strong practical functions in item bank management, computer adaptive test implementation, data post-processing and management and maintenance.
