  2. 一、英语测试的质量评估 • 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); • 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); • 还要考虑施测的可行性问题(practicality); • 以及区分力(discriminating power)。 高中英语命题与考点分析

  3. 考试设计与命题:基本原理 试卷结构 信度 效度 是否保证考试分数的公平性? 是否考了所要考的? 一致性 准确性 分数 高中英语命题与考点分析

  4. 考试设计与命题:基本原理 考试内容 代表性 覆盖面 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 质量 抽样 高中英语命题与考点分析

  5. 1. 效度 • 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。 • 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。 • 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。 • 实际上,由于种种原因,常常不能完全如愿。 高中英语命题与考点分析

  6. 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。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。 • 效度只有高低之分,没有有无之别。 • 谈效度,不能离开具体的测试以及具体的目标。 高中英语命题与考点分析

  7. 影响效度的因素 • 1)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。 • 2)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? 高中英语命题与考点分析

  8. 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。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。 • 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,以避免考生仅因为不认识某些词语或不了解某种文化而做不好题。 • 又如,考词汇的试题, 如何回避无关内容? 高中英语命题与考点分析

  9. 同样,测试的内容 太少、 太多、 太易、 太难 样本太少‘ 不足反映整体 题量太大’ 变成速度测试 测不出考生 的实际水平 测不出考生 的实际水平 高中英语命题与考点分析

  10. 3)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。3)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。 • 4)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。 • 5)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。 • 6)考生方面的一些主观因素。如:考生的积极性,情绪等等。 高中英语命题与考点分析

  11. 2. 信度 • 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。 • 信度的研究必须有比较,通常从三个方面来研究: 高中英语命题与考点分析

  12. 1)测试的稳定性(stability)。常用的方法是测试-再测试法(the test-retest method),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。即第一次测后隔一段时间再测,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。 • 求相关系数,有pearson的积矩相关系数和spearman排列次序相关系数。 • 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,比较两次名次上的差异。 • 相关系数最好高于0.9,至少不低于0.8。系数高,测试稳定性就高。 高中英语命题与考点分析

  13. 2)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。 高中英语命题与考点分析

  14. 3)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。(奇数题与偶数题、前一半题与后一半题) • 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。 高中英语命题与考点分析

  16. 高中英语命题与考点分析

  17. 提高信度的主要方法 • 1)适当增加题量。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。 • 2)注意各题的同质性。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。 • 3)控制好题目的难易程度,提高区分度。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任意一致,测试的相关性就可能提高,信度也就提高了。 • 4)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境中考试。 • 5)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5个方面都有切实可行的办法,因此信度高。 高中英语命题与考点分析

  18. 3. 可行性 • 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。 • 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。 • 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 高中英语命题与考点分析

  19. 4. 区分性 • 测试应该要起到能够区分考生能力高低的作用。 • 测试要具有多大的区分度,视具体情况具体分析。 • 一般的“过关”考试,希望大部分甚至全部的人都通过考试,这时区分度就不宜太高。 • 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 来说,考试目的是为了择优,这就需 要有很强的区分力。 高中英语命题与考点分析

  20. 难易度与区分度 • 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) • 难度值:该数值与难度呈反比,范围在0—1,数值越高,越容易。 • 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。 高中英语命题与考点分析

  21. 高中英语命题与考点分析

  22. 区分度:反映的是试题区分力的强弱程度。区分指数为-1 -- +1. • 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的人多时,区分指数为正数; 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。 高中英语命题与考点分析

  23. 区分指数 高分组答对该题的人数 低高分组答对该题的人数 区分度 每组人数(高分组和 低分组人数应一样) 高中英语命题与考点分析

  24. 为了提高试题的区分度,通常在试测之后要修改或删除区分度低的题目,特别是区分度≤0的。为了提高试题的区分度,通常在试测之后要修改或删除区分度低的题目,特别是区分度≤0的。 • 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。 高中英语命题与考点分析

  29. 1. 单项填空 • 本大题的命制要着重考查语法和词汇知识在特定语境中的应用,要特别注意语境的设置,并保证主干知识的覆盖面。 高中英语命题与考点分析

  30. 1. 单项填空 • [题干] • 由一个句子或一组短对话构成。题干至少包含一个可作为考点的语法结构或意义关系。 • [答案] • 答案选项通常是一个词、短语、结构或交际用语。它是正确理解题干中的语法结构或意义关系的必然结果,也就是,正确答案的选择必须基于对题干结构或意义的正确理解。 • [干扰项] • 单项填空中的干扰方式主要包括(1)词形干扰、(2)词义干扰、(3)用法干扰以及(4)结构干扰。 高中英语命题与考点分析
