2019/062020/02让作业错误绽放异彩——小学数学作业中的错题重生价值及策略探微江苏灌南县长江路小学教育集团硕项湖校区谢一奇专题研究说说解题思路。

学生在各自的展示过程中，交换意见碰撞思想，纠正自己错误的认识，借鉴他人解题经验，优化解题策略，提高各自的解题能力，形成良好的解题习惯。

金无足赤，人无完人。

小学生在数学学习过程中出现误解是一种正常的现象，面对学生在数学解题中的误解，我们要认真审视、弄清缘由、对症下药、化解误解。

为了增强学生理解能力，减少学生认知偏差，消除数学解题错误，我们要立足基础教学，奠定理解根基，遵循个性差异，开展因材施教，关注思考过程，提升解题素养。

但金无足赤，人无完人，小学生在作业中出现错误是正常现象，我们无须自责，也不必责怪学生，我们应正视和善待学生的错误。

作业错误是一种隐藏的教学资源，具有一定的教学价值，我们应关注学生的作业错误，采取有效的策略，利用学生的作业错误，让学生作业中的错题重生，使作业错误绽放异彩。

【关键词】作业错误错题重生价值策略作业是为完成学习任务的一种活动，是消化巩固知识的一种途径。

无论是课堂作业还是课外作业，教师都要进行认真批改，以了解教和学的效果。

几乎所有教师都希望学生的作业正确无误，不希望看到学生作业出现错误。

作业错误是学生学习问题的反映，同时也暴露出教师的教学问题。

但金无足赤，人无完人，学生在作业中出现错误是正常现象，我们无须自责，也不必责怪学生，我们应正视和善待学生的错误。

一般教师处理学生作业错误的方法都比较简单，那就是直接纠正了之，或学生个别订正，或集体评讲，只要把错题订正好就完事了，不大关注学生是否弄清错因，能否有效改正，今后是否不再重犯。

小学数学“错题资源”有效利用的实践与研究开题报告浙江省台州市路桥区金清镇中心小学课题组一、研究的背景（一）现状分析在我们的教学中，学生在课堂上、作业中出现的错误经常是类同的，有些错误学生是一犯再犯，甚至有的学生一道题目需要订正好几次才能订正好。

对于这些错误，如果我们能进一步分析学生犯错误的原因，并能透过错误发现有关问题，在错误上面做些文章，就可变“废”为“宝”，利用这些错误资源为教学服务。

但长期以来，我们的学生往往简单地把自己的错误归结为粗心、马虎、不认真，我们的老师在对待学生学习上的错误，缺乏一种“主动应对”的新理念和策略，导致在教学实践中经常可以看到有相当一部分学生对于相同的错误屡犯不止，学生学习时间的无效流失，影响教学质量。

此时的教师不仅要让学生经历纠错的过程，形成正确的观念与做法，更重要的是让学生反思自身的错误，进而升华为“错误观”的教育。

数学学习中学生出现错误是美丽的，是他们最朴实的思想最真实的暴露，教师一定要平和、理智地看待，并辅之以策略处理，充分利用再生资源，让“错误”美丽起来。

基于以上认识，决定开展《小学数学“错题资源”有效利用的实践与研究》这一课题的研究。

（二）研究的理论依据1．反思性教学的基本理论。

熊川武教授采撷众说之长提出了反思性教学的定义：教学主体借助行动研究不断研究与解决自身和教学目的，以及教学工具等方面的问题，将“学会教学”与“学会学习”统一起来，努力提升教学实践的合理性，而使自己成为学者型教师的过程。

美国当代教育家、哲学家“反思性教学”思想的重要倡导人唐纳德·舍恩在他广为引用的著作《反思性实践者》中，提出了“反思性实践”以及“反思性实践者”的思想，他的“行动中对行动的反思”包含了两层意思，一是“对行动的反思”，二是“在行动中反思”。

所有这些都是指导我们进行“错误资源”再利用要不断反思不断改进。

2．建构主义学习观。

建构主义学习观认为,错误是学生利用已有的知识经验,主动构建新的认知结构时常会产生的一种结果。

错题的常见错误类型和改正方法错题的常见错误类型和改正方法（一）不会的题这类题，主要表现在智力因素培养方面，一般出自知识结构性错误，重做几遍错题是十分必要的，至于具体是几遍这要视你自己对错题的把握的熟练程度而定。

知识结构性错误是我们在初步学习时，没有建立起自身知识结构体系，或者在建立自身知识结构体系时存在了一些漏洞与错误认识。

只有通过重做错题，并认真分析错误原因，归纳总结方法才能把这个漏洞补上，这个纠错总结反思的过程一般一道题用15分钟左右的时间，就可取得后来错误重复出现要花上几个小时的才能取得的收益，就可以补全我们的知识结构体系，锻炼我们的思维能力。

如果不及时纠错与总结反思，有些知识结构性错误会一直存在并且成为以后学习的障碍。

这类知识结构性错误主要有以下三类：1、概念不清这类问题包括知识点凌乱，知识结构散漫，记忆理解不深刻，题目容易混淆，压得学生思想包袱沉重。

处于不同学习层次的同学要根据自己的实际情况，加强训练和记忆，培养自己的宏观思维方式，因人而异地确定自己的学习目标、步骤和解决问题的方案，并且有效地进行目标时间管理和知识结构体系的建立。

2、不能迁移这类问题的产生的原因是因为学生仅仅是依葫芦画瓢而没有真正掌握每一种题型的解题思路或技巧；或处理问题的方式过于死板，虽然知道该题涉及到的知识点，但是却不知从哪里开始无从下手，缺乏解题思路完整的探索过程。

其实无论是哪一类题型，都有解题的一般思路和普遍方法，只要读题仔细抓住某一题型的个体特点，就能顺利将题解出。

加强训练，假以时日便能培养自己举一反三能力，增进解题的灵活性与变通力，并且随时都能够有所感悟，学习就是一种感悟，通过思考有所“悟”使自己的思维能力得到提高。

3、不会应用这类问题往往是因为学生对知识点的理解较为浅薄单一，知其然不知其所以然，也不知道该知识点和其它知识点的联系。

当使用障眼法，把曾经解答过的题变换某些条件，移植一种情景时，就会产生似曾相识的感觉，不再细辨其中的异同，自然会被条件搞昏头。

高考复习中的错题重做与分析高考是每个学生都期待的重要考试，它不仅考察了学生多年来的学习成果，更是对学生逻辑思维和解决问题能力的综合考验。

在备战高考的过程中，错题重做与分析是一项重要的复习策略。

本文将探讨高考复习中的错题重做与分析的意义、方法以及注意事项。

一、错题重做的意义错题重做是一个重要的学习策略，它能够帮助学生巩固知识，消除错误，进一步提高答题准确率。

具体而言，错题重做有以下几个重要的意义：1. 回顾知识点：复习过程中，我们难免会遗忘一些知识点。

错题重做能够让我们重新回顾并理解这些知识点，从而更好地掌握。

2. 探究问题：在重做错题的过程中，我们可以反思自己解题时的思路和方法，进一步探究问题。

这有助于我们加深对知识点的理解，提高解决问题的能力。

3. 弥补薄弱环节：错题重做有助于我们找出自己理解不足或薄弱的环节，并及时加以弥补。

这样可以提高学习效率，避免在考试中再次出现相同的错误。

二、错题重做的方法1. 审题准确：在重做错题之前，我们首先要仔细审题，确保理解题目的意思。

如果对问题有任何疑惑，可以与同学或老师进行讨论。

2. 独立思考：在重做错题时，我们应该避免查看教材或答案，而是要尽力独立思考解题思路和方法。

通过自己的思考，不仅可以巩固知识，还可以培养解决问题的能力。

3. 分析解题过程：在解答完题目后，我们应该对解题过程进行全面的分析。

可以思考自己的思路是否正确，哪些环节容易出错，以及如何避免类似错误。

4. 学会总结：每次重做错题后，我们应该总结经验教训，记录下容易出错的知识点和解题方法。

这样可以形成一个错题集，方便我们复习和回顾。

三、错题分析的注意事项1. 多角度思考：在分析错题时，我们应该从多个角度进行思考，包括知识点的理解、解题思路的合理性以及解题过程中出现的错误。

这样可以更全面地了解自己的问题。

2. 注意常见错误：在错题分析中，我们应该特别关注常见错误，例如计算错误、漏题、概念混淆等。

通过有针对性地重点关注这些错误，我们可以提高解题准确率。
