高中英语命题技巧及试题考点分析方法(课堂)课件.ppt

1、12/13/20221兰 春 寿12/13/20222一、英语测试的质量评估n评估英语测试的质量，首先要研究测试的有效性问题，即效度（validity）；n质量评估要考虑的第二个问题，是测试结果的可信（可靠）程度，即信度（reliability）；n还要考虑施测的可行性问题（practicality）；n以及区分力（discriminating power）。12/13/20223试卷结构试卷结构是否考了所要考的？是否保证考试分数的公平性？准确性准确性一致性一致性12/13/20224考试内容考试内容考试内容是否是大纲的重点？考试内容是否涵盖大纲的主要内容？数量数量质量质量12/13/2022

2、51.效度n简单地说，是指某一种/某一次测试能在多大的程度测出预定要测量的东西，或者能在多大的程度完成预期的测量任务。n我们希望通过测试所测量的是我们想要测量的东西，而且仅仅是想要测量的东西，绝对不是不想测量的东西。n例如测“写作能力”，不要牵扯进“阅读能力”的测试或其他能力的测试。n实际上，由于种种原因，常常不能完全如愿。12/13/20226n因此，效度是程度的问题，可以分成若干等级，如高、较高、中等、较低和低。n效度只有高低之分，没有有无之别。n谈效度，不能离开具体的测试以及具体的目标。12/13/20227影响效度的因素n1）测试的目标不当。测试目标的确定要在测试能够到达的范围之内。英

3、语测试能揭示的，不是受测者在英语学习中的全部情况，而只是那些可测的，可计数的现象。n2）测试的内容不妥。必须使测试的内容尽可能准确地反映测试的目标。命题实际上是一个抽样的过程，要使抽样合理，每一次测试的题项必须有代表性，侧重点要明确 例如：某一大题以考语法为测试目标，如何合理抽样？12/13/20228n以考语法为测试目标的大题，每小题就要尽可能合理地覆盖想测的那些语法点，每小题应该有特定任务，重点考某个语法点。n命题时要尽量避免别的内容来干扰主要内容。由于重点考语法，不是考词汇，不是考文化背景知识，涉及的词语就不宜太难，太偏，而且要用所谓的culture-free items，以避免考生仅因

4、为不认识某些词语或不了解某种文化而做不好题。n又如，考词汇的试题，如何回避无关内容？12/13/20229n同样，测试的内容 太少、太多、太易、太难 样本太少样本太少 不足反映整体不足反映整体题量太大题量太大 变成速度测试变成速度测试测不出考生测不出考生的实际水平的实际水平测不出考生测不出考生的实际水平的实际水平12/13/202210n3）测试方法不对。测试的方法要与测试的内容相适宜。如：考口试要用口试法。n4）测试组织不好。测试需要严密、科学的组织工作，组织得好将有利于提高测试的效度和信度。n5）没有合理使用分数。要正确有效地使用通过测试获得的包括分数在内的各种数据。n6）考生方面的一些主

5、观因素。如：考生的积极性，情绪等等。12/13/2022112.信度n信度是指考试结果的可信程度，实际上是指考试的一致性，所要了解的是考试在多大程度上具有一致性。n信度的研究必须有比较，通常从三个方面来研究：12/13/202212n1）测试的稳定性（）测试的稳定性（stability）。）。常用的方法是测试常用的方法是测试-再测再测试法（试法（the test-retest method)，就是用同一套试卷在，就是用同一套试卷在尽可能相似的环境中对同一批考生测试两次。即第一次测尽可能相似的环境中对同一批考生测试两次。即第一次测后隔一段时间再测，间隔的长短按需要而定。比较两次测后隔一段时间再测

6、，间隔的长短按需要而定。比较两次测试的成绩，求出相关系数，判定测试的稳定程度。试的成绩，求出相关系数，判定测试的稳定程度。n求相关系数，有求相关系数，有pearson的积矩相关系数和的积矩相关系数和spearman排排列次序相关系数。列次序相关系数。n用前一种方法只要知道总人数，两次的分数就可以算出来。用前一种方法只要知道总人数，两次的分数就可以算出来。n用后一种方法，是研究两次测试的次序相关（用后一种方法，是研究两次测试的次序相关（rank correlation),根据成绩把考生两次测试的名次排出来，根据成绩把考生两次测试的名次排出来，比较两次名次上的差异。比较两次名次上的差异。n相关系数

7、最好高于相关系数最好高于0.9，至少不低于，至少不低于0.8。系数高，测试稳。系数高，测试稳定性就高。定性就高。12/13/202213n2）测试的等值性（equivalence）。常用等值（卷）法（the equivalent-forms method)。用同一测试的两份等值试卷对同一批人进行测试，比较两次的成绩，算出相关系数，判断两次测试的等值性。12/13/202214n3）测试的内部一致性（internal consistency）。测内部一致性用得比较多的方法是分半法（split-half method）。用一份试卷施测，然后把试卷分成题数相等的两个部分，求这两部分分数的相关系数。（

8、奇数题与偶数题、前一半题与后一半题）n只计算客观题，用Kuder Richardson的 KR21公式，如果是主观题，则用Cronbach的公式。12/13/20221512/13/20221612/13/202217提高信度的主要方法提高信度的主要方法n1）适当增加题量。）适当增加题量。题量增加，试题的覆盖面大，题目的代表性题量增加，试题的覆盖面大，题目的代表性好，测量误差就在一定程度上减少。好，测量误差就在一定程度上减少。n2）注意各题的同质性。）注意各题的同质性。即题目的一致程度，如：题型一样、题即题目的一致程度，如：题型一样、题量一样、覆盖面一样、指导语一样，编排一样。量一样、覆盖面一

9、样、指导语一样，编排一样。n3）控制好题目的难易程度，提高区分度。）控制好题目的难易程度，提高区分度。题目难易程度适当，题目难易程度适当，区分度高，对两次或多次测试考生按照成绩高低排列次序就比较区分度高，对两次或多次测试考生按照成绩高低排列次序就比较任意一致，测试的相关性就可能提高，信度也就提高了。任意一致，测试的相关性就可能提高，信度也就提高了。n4）尽可能消除各种干扰因素。）尽可能消除各种干扰因素。使全体考生在十分相似的考试环使全体考生在十分相似的考试环境中考试。境中考试。n5）改进评分方法，提高评分的客观性和准确性。）改进评分方法，提高评分的客观性和准确性。标准化测试在以上标准化测试在以

10、上5个方面都有切实可行的办法，因此信度高。个方面都有切实可行的办法，因此信度高。12/13/2022183.可行性n测试无论规模大小，其过程分为三个阶段：准备阶段、施测阶段和评分阶段，每个阶段都有可行性问题。n对于大规模的考试，命题人员尽可能考虑周到，为后续工作提供方便。n例如：试卷的版面设计要规范、方便考生、阅卷教师和工作人员；为阅卷教师提供的答案要明确、全面，评分标准要详尽，答题卡的设计要方便计算机阅卷。编排12/13/2022194.区分性n测试应该要起到能够区分考生能力高低的作用。n测试要具有多大的区分度，视具体情况具体分析。n一般的“过关”考试，希望大部分甚至全部的人都通过考试，这时

11、区分度就不宜太高。n高考是选拔类的考试，区分度应该怎样？对于具有选拔性功能的高考对于具有选拔性功能的高考来说，考试目的是为了择优，这就需来说，考试目的是为了择优，这就需要有很强的区分力。要有很强的区分力。12/13/202220难易度与区分度n测试评分结束后，应依据测试的结果进行题项分析（item analysis），计算每小题的难易度（facility value）和区分度（discrimination index）n难度值：该数值与难度呈反比，范围在01，数值越高，越容易。n把试卷中每道题的难度值加起来除以题数，所得的值为整卷的难度值。12/13/20222112/13/202222n区分

12、度：反映的是试题区分力的强弱程度。区分指数为-1-+1.n在计算区分指数时，把考生按照所得的总分的高低分成人数相等的高低两个组。当高分组答对某题的人数比低分组答对此题当高分组答对某题的人数比低分组答对此题的人多时，区分指数为正数；的人多时，区分指数为正数；当两组人数一样时，区分指数为当两组人数一样时，区分指数为0；当前者人数反比后者少时，区分指数为负数。当前者人数反比后者少时，区分指数为负数。12/13/202223高分组答对该题的人数区分指数区分指数低高分组答对该题的人数每组人数（高分组和低分组人数应一样）区分度区分度12/13/202224n为了提高试题的区分度，通常在试测之后要修改或删除

13、区分度低的题目，特别是区分度0的。n把所有题目的区分度加起来除以题数就获得整份试卷的区分指数。12/13/20222512/13/202226n67.The purpose of the passage is to show you how to _.nA.play your cards right nB.use your cards abroad nC.draw cash with your cards nD.pay for goods with your cards12/13/202227n一道试题至少由以下三个部分组成：题干（文本、图片、音频、视频等）（辨析、理解、分析、推理、概括、产出
