| 摘 要： | 教育评估中的信度问题一直是人们所关注的焦点,它直接影响到评估的准确性及评估的公平性.传统信度分析方法(如经典测量理论)不能探查和分解各种误差来源,更难考察测量情景变化所引起的误差的相对变化,且对多变量的信度分析没有一个综合统一的评价指标,这给实际工作带来诸多不便.该文采用一种全新的信度分析方法──多元概化理论(MGT),对某次实际教育评估的资料进行信度分析.研究结果表明,采用多元概化理论的方法与技术对教育中的评估作信度分析有强大功能,它能深入分析各种评估误差对评估信度的影响,并能为改善和提高评估的信度及评估的准确性提供指导,值得推广.

| Abstract: | The reliability in education assessment,on which people always focus,influents the accuracy and the fair of assessment.Traditional methods such as CTT could not research the relative change of error with the change of measurement situation.This paper applied a new method called MGT to analyze the reliability of education assessment.It displayed that MGT had a great power on reliability analysis,such as distinguishing various error effection on reliability,instructing the improvement of reliability and it's accuracy. |
