【摘要】：文章以PETS-5为例,在设计并实现机考形式后,选取出国培训班学生共404人参加了该机考测试。测试结束后,通过在线问卷调查的形式调查了被试对该机考形式的感受与意见,并收集了考生参加PETS-5纸笔考试的考试成绩。研究结果表明:(1)该机考总体的Alpha信度为0.82,各部分为0.63~0.65,具有较好的内部一致性信度;(2)该机考各部分的相关系数为0.34~0.43,与纸笔考试各部分相关的结果基本相近,具有较好的结构效度;(3)该机考成绩与纸笔考试成绩的相关系数为0.709,具有较好的效标关联效度;(4)该机考模式对于男生和女生是公平的,试题在性别上不存在项目功能差异;(5)关于测验总分及各部分性别差异t检验结果显示,男女考生仅在阅读理解成绩上存在性别差异,男生的平均成绩高于女生。
[Abstract]:Taking PETS-5 as an example, after designing and implementing the machine test, 404 students from overseas training courses were selected to take part in the test. At the end of the test, the online questionnaire was used to investigate the participants' feelings and opinions about the form of the test, and the test scores of the examinee to take the PETS-5 paper and pen test were collected. The results show that the overall Alpha reliability of the machine is 0.82and that of each part is 0.630.65.The reliability of each part of the test is 0.340.43, which is similar to the result of each part of the paper and pen test, and the correlation coefficient of each part of the test is 0.34 ~ 0.43, which is similar to that of each part of the paper and pen test, and the correlation coefficient of each part of the test is 0.34 ~ 0.43. The correlation coefficient between the test scores and the test scores of paper and pen is 0.709, and the correlation validity of the test is better than that of the standard. (4) the test model is fair to boys and girls. There is no item function difference in the test question (5) about the total score of the test and the gender difference of each part, the result shows that there is only gender difference in the reading comprehension achievement of male and female examinee, and the average scores of male and female students are higher than that of female student.
