1、英语中考命题的基本英语中考命题的基本理论与实践理论与实践第一部分第一部分 英语测试的基本理论英语测试的基本理论一、英语测试的类型1、常模参照考试将某个学生的成绩与其他学生的成绩进行比较；(不不适适合合用用于于平平时时课课堂堂测测验验，因因为为课课堂堂测测验验的的目的不是把学生分为三六九等。目的不是把学生分为三六九等。)2、标准参照考试将考生的成绩与事先制定的标准进行对比，不受其他考生成绩的影响。即用一个既定标准/尺度来衡量学生的学习结果。二、试题命制应注意的“四度”n n1 1、难度、难度n n题目难度是题目的难易程度，它是题目对被题目难度是题目的难易程度，它是题目对被试者知识和能力水平的适合

2、程度的指标。测试者知识和能力水平的适合程度的指标。测验难度水平的适当与否取决于考试的目的、验难度水平的适当与否取决于考试的目的、性质和题目的形成。对于一般的常模参照考性质和题目的形成。对于一般的常模参照考试而言其目的是测量个体差异，其题目的平试而言其目的是测量个体差异，其题目的平均难度最好为均难度最好为0.500.50，各题难度可在，各题难度可在0.500.50+0.200.20之间。当考试用于选拔时，题目的难度值应之间。当考试用于选拔时，题目的难度值应更多地接近录取率。更多地接近录取率。n n试题的难度通常分为A、B、C、D四个层次：n nA类试题为容易题，相当于70%以上的考生能够正确回答

3、，难度值处于0.7-1之间。n nB类试题为中等偏易题，相当于50%-70%的考生能够正确回答，难度值处于之间。n nC类试题为中等偏难题，相当于30%-50%的考生能够正确回答，难度值处于之间。n nD类试题为难题，相当于30%以下的考生能够正确回答，难度值处于0-0.3之间。2、区分度、区分度 n n区分度是指考试题目对学业水平不同的考生的区分程度的指标。具有良好区分度的题目，对考生有较强的鉴别能力，水平高的考生得分高，反之则得分低。在常模参照考试中，题目的区分度是一个非常重要的指标，一般依据选拔的目的和选拔率来确定。对于标准参照考试，只有及格线附近的考生对题目的区分度要求较高。3、信度、

4、信度n n信度是指测试的结果是否稳定、可靠。如果让一个考生把同一份试卷做两次，如果两次结果相近，那么测试具有较高的信度。n n主观题的信度尤其重要。由于评分者的信度难以保证，主观题的信度也往往难以保证。4、效度、效度效度是指测试是否有效地考查了希望考效度是指测试是否有效地考查了希望考查的内容。查的内容。就语言水平测试而言，效度直接关系到就语言水平测试而言，效度直接关系到测试结果能否准确反映考生的语言能力。测试结果能否准确反映考生的语言能力。考试内容、考试形式与命题技术都直接考试内容、考试形式与命题技术都直接关系到测试的效度。关系到测试的效度。如果通过让学生写单词的音标来考查学生的语音能力，那么

5、测试就缺乏效度。能写音标不等于能正确发音。现在中考中经常使用的间接口语考试的效度也不高。如果不讲究命题技术，试题也会缺乏效度：Which of the following does paper burn in?A.CO2 B.N2 C.O2 D.H2三、命题原则三、命题原则1.基础性原则n n考试内容考试内容：基础知识 基本技能 综合运用语言的能力 交际能力 用英语做事2.客观性原则n n测试理论测试理论测试理论测试理论n n分离测试：分离测试：分离测试：分离测试：一般以词、句形式呈现，缺乏语用一般以词、句形式呈现，缺乏语用情景，孤立测试某一知识或能力，信度高，效情景，孤立测试某一知识或能力，

6、信度高，效度相对较低。度相对较低。n n综合测试：综合测试：综合测试：综合测试：一般以语篇形式呈现，具有一定的一般以语篇形式呈现，具有一定的语境，测试某一知识或能力，信度，效度相对语境，测试某一知识或能力，信度，效度相对平衡。平衡。n n交际语言测试：交际语言测试：交际语言测试：交际语言测试：以语篇形式呈现，具有较为真以语篇形式呈现，具有较为真实的情景，强调以互动的形式，测试综合运用实的情景，强调以互动的形式，测试综合运用语言的能力，信度较低，效度高语言的能力，信度较低，效度高3.科学性原则科学性原则n n行文准则行文准则行文准则行文准则 无知识性错误无知识性错误 无文字表达错误无文字表达错误

16、book store.B.In a library.B.C.In a laboratory.2、单项选择题、单项选择题n n侧重考查学生在一定的语境中灵活运用语法、词汇等语言知识的能力。单项填空题要注意加大考点的覆盖面，力求题干语境真实、语义丰富、表达地道。n n 由于近年来单选题数量有逐步减少的趋势，因此该题型考查范围尽可能局限于语法项目。n n（实例略）3、完形填空题、完形填空题a)所选短文应该主旨明确，大意清楚，有较好的连贯性；b)语言难度适当，题材是学生比较熟悉的内容；c)所选短文的长度要适当。太短的材料不利于挖空，可能使删词过于密集；太长的材料则会增加学生的阅读负担和考试时间；d)不

17、宜在短文的首句和末句中挖空；e)空白之间的间距要适当。一般间距为7至9个单词为宜。间距过小会增加试题的难度；间距太大则会降低难度，同时增加材料的篇幅和阅读的时间；f)要注意所删词语在文段中确实有上下文线索，使学生能够依据这些线索进行推断。g)不宜把语言知识以外的其他知识作为考查的重点，如一般不把专有名词等挖空。h)完形填空属于阅读理解的范畴，不要考纯语法的项目。One day,a young man called Tom came 1 see the great artist,Da Vinci（达 芬奇）.He wanted 2 drawing.Da Vinci gave him 3 egg
