第三篇:初三英语期中考试试卷分析及总结

鹅公中学 叶月平 期中测试阅卷结束后我对英语试卷做了统计分析和调查结果表明英语成绩不够理想。在本次期中测试中我教初三1和4班英语共有2个班三1班共57人参加考试及格38人优秀7人最高分113最低分38三4共63人参加考试及格3人优秀0最高分86最低分17。

一、试卷特点 试卷紧扣教学大纲的要求着重考察了学生的基础知识以及在掌握知识的同时对基础知识的运用。试卷总体感觉不难但是从学生角度反应出试题具有较大的迷惑性要求学生能够排除干扰因素并且注意知识细节。

二、本试卷在命题上的特点 听力部分三大题考查了学生的理解日常英语的能力相当部分题目难以直接从录音对话中找到答案学生必须通过思考从词语释义、句意理解或段意理解等不同方式悟出正确的选择内容难度不大而且语速不快但部分学生本来基础知识欠熟练而且没有掌握好答题技巧也就是说没能按老师平时的要求在听录音前做到反复看透听力的题目所以答题反应慢而失分说明学生的听力理解能力还待提高。如 单项选择题。试卷要求所有的考点都不是孤立地考语法知识而是将他们放在特定的语境中学生必须看懂题干的全部内容以后经过思考方能选出正确答案。一些中下层生失分多集中在语法方面。 完型填空。大部分学生比平常测试的成绩要好一些上层生得分较高其中原因一是短文所描述的内容较容

易理解学生对这方面了解较多。 阅读理解。第

一、二篇短文内容较为简单所选的答题大体都能一目了然但7选5这题错的较多学生不能把握短文意思而且学生很多审题不清。 书面表达。明显检查学生运用语言能力这是学生成绩差距最大的一题15分的题目差的只能得23分普通的一般是56分左右好的约910分关键是学生很多以汉语的思路来写作以至不能正确表达意思从中反映了学生句子结构还不熟练语言表达能力弱语法错误多的缺点。

三、学情分析 总的来说这次考试成绩不理想优秀率偏低尖子生还没有发挥水平低分较多两极分化的距离还没有缩少。通过整体的分析反映了学生在复习中基本上能领会课堂的要点要求一些知识点在堂上反复出现的掌握得较牢固但是运用这些知识去解决实际问题的能力较差这与课后的练习有关说明了部分学生对课后的练习作业不够重视、缺乏主动性而且解题的依赖性强缺乏独立的思考能力另外对于一些相关的语法知识和句子的构成学生的遗忘率也很高。

四、今后的教学措施 针对目前学生状况要提高成绩首先要端正学生思想态度在保证课堂质量的同时一定要确保课后的“自我消化”环节尤其是中上层学生只有通过练才能达到知识的巩固、才能学会灵活运用、才能发现问题查漏补缺、才能培养独立的解题能力。结合实际我们的具体计划 第

一、加强听力方面的练习在有可能的情况下多给学生开展听力训练。认真用好《初三英语听说训

练》平时组织学生定期训练真正提高学生的听力水平。 第

二、强化单词的记忆并结合目前的情况对优生及中上等的注意培养他们对一些多义词、兼类词的实际运用能力提高他们基础题的解题水平。 第

三、抓好语法的分类复习在此过程中就当前所暴露出来的弱点开展进行通过分析试题教会学生学会归纳知识并如何把识记的内容用于实践中 第

四、完形填空及阅读理解部分平时应加强训练同学们的答题速度及答题质量。有针对性地组织学生组织阅读训练期中考试后组织学生用好《初三英语读写训练》确保每周训练12次。 第

五、争取改变学生凭感觉做动词填空的方式。通过时态语态固定用法等培养学生动词填空的能力。 第

六、指导学生做好短文填词这一中考题型首字母填空是一项综合能力考查题要求学生能读懂短文然后选用恰当的词进行填空我们需要对学生进行方法指导并多做这类题目才能真正提高学生的能力。 第

七、书面表达是一个薄弱环节主要是学生组句的能力差语法漏洞多不会审题的原因所以在以后要重视对作文的评讲及优秀范文的分析。
