质量监测诊断与分析报告

1、2014年试验区初三下学期模拟测试二质量监测诊断与分析报告（语文）技术支持：杭州导领科技有限公司联系电话国教育测评网（）第一章 学科成绩报告  学科水平与差异评价帮助我们从不同角度，了解和发现某科考试中整体样本、学校、 班级之间的差异及各学科之间的差异，力求评价更加客观公正；也有利于各学科 教师发现各自的优势和存在的不足，帮助师生总结成功经验，找出问题根源。一、目标水平的差异分析  目标水平，即达到目标要求的指标，包括满分人数、优秀人数、及格人数、 低分人数、满分率、优秀率、及格率和低分率。单位总人数平均分优秀人数良好人数及

4、6%、5%来确定六条线的分数位置）。  上线指标评价的优点：克服了优秀、良好、及格、低分等目标参照评价指标会受试卷难度影响的不足， 不管试卷难度如何都能进行比例合理的评价。上线指标包括各学科和总分上线与上线率的统计图表。名称a线人数b线人数c线人数d线人数e线人数f线人数实验区458417473337559503龙川中学1378691586440莲花中学41118203845福田中学465882558087西培中学7920256073慧明中学262939355241公民中学81321234029第一中学8831276654石岩中学797667426453第二中学102926

18、; 线性标准分是将原始分数与其平均数之差除以标准差所得的商数。它是以 标准差为单位度量原始分数离开平均数的量数，可以表示一个原始分数在团体中所处的位置。常用的线性标 准分包括线性标准分z和线性标准分t。  正态化标准分和线性标准分计算方法不一样，不是有公式计算而来，需要 利用线性转换的技术。非线性转换的结果是把偏态分布强制扭转成为标准正态分布形态。转换生成的正态化 标准分消除了分布形态的影响，才具有真正意义上的“可比性”和“可加性”，为科学、准确地对不同测验的分 数进行比较和分析奠定了基础。以学校的正态化标准分确定定位学校在全市的位置，横向了解学校、班级各 科之间

22、图第二章 试卷试题分析一、试题汇总指标  汇总指标包括满分值、平均分难度指数p，难度指数z'、难度指数 和区分度。 测题的难度是指测题的难易程度。表示测题难易程度的数量，称为测题的难度指数，一般用p来表示。  由于p难度指数是正确回答试题人数的比例（客观题），或全体被试在该题上的 平均数与试题满分的比例（主观题）。这种比例位于“顺序量表”上，它们之间是不能进行语文运算的。不同难度只 能表示出试题的难易程度之间的大小、位次关系，但不能表示出试题的难易程度之间差异的数量关系。为了对测题 之间的难易程度做进一步统计分析，教育测量学中将难度指数表示在位于

23、“等距量表”上，转化为“正态化的等距的 难度指数”，即难度指数z'和难度指数。题目满分平均分难度指数p难度指数z难度指数区分度一25.017.550.70184.4710.880.30一.110.08.800.88033.838.300.25一.22.01.370.68584.5211.060.35一.32.01.100.54794.8812.520.49一.43.02.700.89993.727.870.24一.53.01.170.39115.2814.110.37一.62.00.920.45875.1013.410.17一.73.01.480.49505.0113.050.40二4
