初中数学易错题的分析及对策一、初中数学易错题的成因1. 概念理解不透彻。
数学概念是学习数学的基础，如果学生对数学概念理解不透彻，就难以正确解答数学题目。
例如，在代数式中，学生可能会将同类项的概念混淆，导致解题错误。
2. 运算错误。
初中数学涉及到大量的运算，如果学生没有掌握好运算规则，就容易在运算过程中出现错误。
例如，在解一元二次方程时，如果学生没有掌握好平方根的概念，就容易在运算中出现错误。
3. 审题不认真。
学生在解答数学题目时，往往存在审题不认真的情况，导致无法正确理解题意，从而出现解题错误。
例如，在求解函数的增减性时，学生可能会忽略自变量的取值范围，导致答案错误。
4. 缺乏解题技巧。
初中数学题目越来越灵活，如果学生缺乏解题技巧，就难以正确解答一些较难的题目。
例如，在求解最值问题时，如果学生没有掌握好函数的思想和数形结合的解题技巧，就难以正确解答题目。
二、初中数学易错题的对策1. 强化概念理解。
学生应该加强对数学概念的理解，可以通过多阅读教材、多做练习题等方式来加深对数学概念的理解。
同时，学生还应该学会将数学概念进行分类和归纳，从而更好地掌握和理解数学概念。
2. 掌握运算规则。
学生应该掌握好运算规则，可以通过多做练习题和总结归纳等方式来加深对运算规则的理解和记忆。
同时，学生还应该注意在运算过程中细心认真，避免因粗心大意而导致的错误。
3. 认真审题。
学生应该认真审题，仔细分析题目中的条件和问题，确保正确理解题意后再进行解答。
同时，学生还应该养成良好的解题习惯，例如先分析题目的条件和问题，再根据条件进行推理和计算。
4. 培养解题技巧。
学生应该通过多做练习题和总结归纳等方式来培养解题技巧。
同时，学生还可以通过参加数学竞赛等活动来提高自己的解题能力和思维水平。

- 196 -校园英语 /“错综”复杂——初中英语易错题成因分析及对策苏州市平江中学校/张璐【摘要】考试是检查、评定学生学习效果的一种方法。
在考试中，有部分题目的错误率明显高于其他题目。
分析这些易错题的成因，找到有效的对策，对于提高教学效果和学习成绩有积极作用。
【关键词】夯实基础 审题习惯 检查 错题集一、易错题成因分析1.基础知识不扎实导致易错。
易错题，并不是在考试中产生的，考试只是一种体现，其根本原因在于基础知识不扎实，也就是说，根源在平时的学习上。
以单词拼写为例：有同学经常会把一些单词写错。
如：first 写成frist ，attack 和attract 不分。
这类易错题反映的是语音基础知识不扎实和学生音形结合的能力的缺失，会严重影响到以后的英语学习。
再如，以语法易错题为例： My father ____live in the city ，but he ____living in such a place.” 当教师讲解“used to ”和“be used to ”时，有些学生满足于当时听懂，以为自己会了。
其实在此知识点的理解、运用还有很大的缺陷。
以上两例看出，易错的根本原因是基本功不扎实，未掌握知识点.2.缺乏良好的解题习惯和科学的思考过程导致易错。
在考试中学生因为缺乏良好的解题习惯和科学的思考过程也会导致易错题。
3.信息提取缺失。
解题的第一步就是通过审题来获取有用信息，而信息提取缺失就是常见的问题之一。
以选择题为例：在答案的选项中，总有一些干扰项。
例如：There are trees on ____ side of the street.A.all B.both C.each D.either 。
若学生未能从题目中提取到side 是单数这个信息，那么看到前两个选项，就立刻想到街道有两条边，而both 是指两者，就选了B ，甚至不看C 、D 答案导致错误。
又如词形变化，也是易错题型。
学生的错误原因主要还是信息提取缺失。
西医临床执业医师易错100题1、第二孔未闭型房间隔缺损血液动力学改变，不应出现的是（）。
A.左房.左室增大B.右房.右室增大C.肺循环血流量增多D.体循环血流量减少E.以上均不是【答案】A2、关于外伤性下视丘损伤，下列哪样是错误的A.早期意识障碍B.早期锥体束征C.高热或低温D.消化道出血或穿孔E.尿崩症【答案】B3、脊髓灰质炎病人应自起病日起至少隔离A.5天B.10天C.20天D.30天E.40天【答案】E4、当放射性同位素14C、15N同时标记的天冬氨酸进入动物体内时，有部分化合物将存在标记原子。
