1、五年级数学期末测试试卷分析一、典型问题分析1、分析问题、解决问题的能力欠缺。第6题此题第一个空，学生能直接利用公式计算出来。但是第二个空，需要学生仔细读题，分析题意，如果遇到困难可以借助图来理解，但是有近45%的学生没有很好的理解好题意，计算方法不当，出现错误。在教学中，教师要注意发现学生学习困难所在，针对不同题型教给学生解决问题的方法。第13题此题得分率为仅为4.3%。这道题一是考察学生是否能灵活运用三角形的面积公式来解决问题，二是考察学生对梯形面积的理解是否到位。要判断阴影的面积是否相等，关键是看这两个梯形的下底是否相等。题中只说了面积和高相等，我们只能推断出梯形的上下底之和相等，不能确定

2、下底是否相等，因此阴影面积无法比较。学生在完成此题时不能综合运用所学的问题，来解决新的问题，不排除有部分学生根本就没有分析好题目要求，更别说解题方法了。因此，在平时教学中，要引导学生讲解题思路分析清楚，多说，必要时多写。第22题（2）的得分率只有25%左右。大多数学生没有看出来鼻子是由两个三角形组成的。一方面说明学生的观察能力较弱，学生没有从直角符号入手，发现给出的是两个三角形的高，还在在头脑中也缺乏一定的想象能力，没有把组合图形转化为简单图形。另一方面可看出学生没有分析解决问题的方法，遇到新问题，他们不能开动脑筋，灵活运用所学知识去解决。2、观察、推理能力有待提高第10题此题的得分率仅为55

3、%。此题看起来是比较简单的，但是学生缺乏耐心，没有仔细观察每个矩阵变化规律，没有认真分析，从而没有发现正确规律。只要学生先发现每个矩阵的共同点，“都多余一个圈”，再观察剩下矩阵个数的特点，就很快能发现规律。这也暴露出学生平时的发现矩阵规律时，没有养成冷静观察、思考的好习惯，不排除有部分学生根本不知道如何入手。第16题此题的得分率为65.2%。出错原因是学生没有认真观察图形变化的规律，无法抓住规律来确定图像。以后引导学生这样观察：先看按什么方向运动，再看每次运动了几个小格，就能找到规律，得到答案了。第21题此题（3）学生观察不认真，没有分析好何为“增加最快”是这道题出错的主要原因。以后教学中，一

4、定要追问学生“你是怎么知道的”。（4）得分率为0%，此题在平时练习中没有出现过，几乎所有学生都不具备解决此题的能力。这道题不但需要读懂题，理解题的意思，更要注意单位名称的统一，就这道题而言，对学生来说，解决起来的确是很困难的。另外，学生数形结合能力有待提高。3、计算能力有待提高第18题得分率为77%。学生在计算时由于通分不准确，所以出错。有个别同学计算能力和准确性太差，有待加强训练。另外，在应用题中，也有学生计算出错，如“5050=250”等。4、灵活解决实际问题能力不足第25题得分率为61.4%。此题在平时复习时出现过。考试时，学生不能灵活运用梯形的面积公式，先计算出上下底之和来计算，只会死

5、搬公式，找不到上底和下底，没有解答此题。第28题此题需要学生综合运用所学知识来解决，得分率仅为33.2%。原因一是学生没有读懂题意，没有分析好数量关系就盲目计算；二是单位间的换算不正确；三是没有结合实际生活来理解，缺少与生活的联系。三、今后工作中需要改进的措施1、加强基础知识的落实。教师要对本册内容中的知识点有一个明确的了解，并在平时的教学中逐一落实。改革课堂教学，提高课堂教学质量。老师要努力从学生的实际情况出发，要备情境以激发兴趣，要重视迁移规律的运用以形成方法。老师要提高课堂教学效率，过程教学要到位，给学生探索知识、解决问题的时间和空间。要注意不同阶段的练习作用，让学生练有目的，练得有趣，

6、练有所得。通过不同的有针对性的练习，帮学生理解知识、运用知识，形成技能，形成良好的习惯。2、重视解题方法的指导。教师要了解各种解题方法，如假设、推理、转换、解方程等，在平时解决问题中指导学生进行运用。3、鼓励学生用数学眼光去观察生活，研究问题。利用教材，又要走出教材，重视对教材例题、习题资源的开发；同时，又要结合学生身边的生活实际，丰富数学教学，以体现数学的价值，培养学生应用数学的意识。4、培养学生收集和处理信息的能力。能从复杂的信息中提出有关数学的信息和相关的有用信息。5、让学生养成静静的思考问题和做数学的习惯。6、提高学生检查的有效性，教会学生一些检查的有效方法。7、加强后进生的辅导，重点

7、放在50分-60分之间学生的辅导。重要的是帮助他们建立学习数学的自信心。要分析差生的原因，确保每单元每阶段基本过关。采用多种形式、方法帮助学困生，要提倡学生之间的互相帮助，让每个学习好的学生都成为老师的助手。8、继续做好优生的辅优工作，增加他们学习数学的兴趣，从而自觉的学习。9、提高学生解题速度。QcWA3PtGZ7R4I30kA1DkaGhn3XtKknBYCUDxqA7FHYi2CHhI92tgKQcWA3PtGshLs50cLmTWN60eo8Wgqv7XAv2OHUm32WGeaUwYDIAWGMeR4I30kA1DkaGhn3XtKknBYCUDxqA7FHYi2CHhI92tgKQ
