基于计算机自适应的大学生社会责任感测验

The College Students′Social Responsibility Testing Based on Computerized Adaptation

构建基于计算机自适应的大学生社会责任感测验的题库,并基于真实数据模拟CAT过程,检测CAT的测验效率并探讨用CAT测量社会责任感的可行性.使用探索性因素分析对测验进行单维性检验,根据项目反应理论选择高质量的项目,构建基于计算机自适应的大学生社会责任感测验(CAT-SRS).然后,基于纸笔测验的实测数据进行CAT模拟,验证CAT-SRS的有效性.研究结果表明:CAT-SRS符合项目反应理论等级反应模型的假设,各个参数比较理想,测量结果与5个原量表纸笔测验结果的相关性较高.CAT-SRS可在测验长度较短时实现对大学生社会责任感的准确测量.

Using exploratory factor analysis,a single-dimensional test is carried out in this paper.The high-quality project is selected according to the item response theory(IRT),and the college students′social responsibility test(CAT-SRS)is built based on computerized adaptation.Then,based on the measured data of the paper and pencil test,the cat simulation is carried out to verify the effectiveness of CAT-SRS.The results show that CAT-SRS meets the assumption of the graded response model of IRT,and parameters of items are ideal,and the correlations between the results of CAT-SRS and the five original paper and pencil tests are relatively high.CAT-SRS can exactly measure social responsibility of college students when the test length is relatively short.
