教育测量中难度与区分度的计算方法 - 2 ) the result of item analysis shows that most of the index of item discrimination is above 0 . 2 and the coefficiences are above significant level
2 、项目分析结果表明，各项目的相关系数均达到差异显著，区分度一般达到0 . 20左右。 - In the previous study on value - directon of schooling , there exist several deficiencies : statements about the conceptual precondition , such as “ times ” , “ schooling ” , “ value of schooling ” and “ humans ” , are vacant ; the thinking mode of dualism is commonly employed ; discrimination , standpoint and dimension are not consciously arrived at
在已有的学校教育价值取向的理论研究中，依然突出的问题是缺乏对“时代” 、 “学校教育” 、 “学校教育价值” 、 “人”等观念性前提的研究，二元对立的思维方式依然比较普遍，研究中的区分度、立场、视角等问题尚未获得自觉。 - The research work presented a large quantity of debris characteristics parameters , and especially made a thorough study on the characteristic description of sediment chain graph ; meanwhile , the sensibility , differentiation and information redundance analyses of the characteristic parameters also supplies the quantitative indexes for the filtration and optimization of the debris characteristic parameters ; in addition , the debris fusion decision recognition method based on the proof fusion theory and the comprehensive debris recognition flow provide reliable recognition arithmetic for debris recognition ; and lastly , the fault fusion diagnosis judging method based on ferro - graph and spectral analysis provides the basic diagnosis method in theory for multi - fault premonitory diagnosis system of aero - engine
本文研究工作提出了大量磨粒特征参数，尤其深入研究了沉积链谱片的特征描述问题；同时，特征参数的敏感性、区分度与冗余度分析为磨粒特征参数的筛选优化提供了量化指标；另外，基于证据融合理论的磨粒统计融合决策识别方法以及磨粒综合识别流程为磨粒识别提供了可靠的识别算法；最后，基于光谱和铁谱信息的磨损故障融合诊断决策方法为发动机多故障征兆综合诊断系统提供了基本的诊断理论手段。 - The second chapter discusses the methods for statistics and analysis of test results from the point of view of educational statistics and measurement . it includes the application of mathematical statistics methods and the summarization of education measurement targets of test quality analysis , and also the concepts , features , methods and correlation of difficulty , discrimination , reliability and validity are discussed . at the end of this chapter , some typical theories are introduced in brief
第二章从教育统计和教育测量的角度出发，从理论上探讨了考试结果统计分析的方法，包括常用的数理统计方法的应用，归纳总结考试质量分析的教育测量学指标：难度、区分度、信度、效度，论述了四度分析的概念、特点、方法和相互关系，并对目前常用的测量理论进行了简要介绍。
