摘 要:在小学数学教学中,教师不仅要教授学生相应的解题方法和学习技巧,更要引导学生根据自己的错题和错题思维,来将错就错。将错误进行转换,化错为宝,进一步优化学习方式和解题方式,促进小学中高年级的学生的深度学习,为以后的数学学习奠定良好的基础。因此本文主要探究了在小学中高年级教学中,合理利用生成资源,促进中高年级深度学习的策略途径。

Turning mistakes into gold and turning mistakes into treasure
——Rational use of generative resources to promote deep learning in middle and senior grades

【Abstract】In primary school mathematics teaching,teachers should not only teach students the corresponding problem-solving methods and learning skills,but also guide students to make mistakes according to their own mistakes and wrong thinking. We should transform the mistakes into treasure,further optimize the learning methods and problem-solving methods,promote the deep learning of middle and senior grade students in primary school,and lay a good foundation for future mathematics learning. Therefore,this paper mainly explores the strategies and ways to make rational use of generative resources and promote in-depth learning in primary school.

小学阶段的学生由于年龄较小,理解能力、邏辑思维能力还处于成长阶段,在理解和解答数学问题时会不可避免的出现错误。这就要求教师给予合理处理,一方面,要充分发挥自身引导作用让学生正视错误,另一方面,也要将其转换成再生的教学资源,化错为宝,让学生在分析、解决的过程中逐步养成良好的学习习惯,避免因处理不当而导致学生学习积极性降低等情况。
1.利用学生学习错误,激发学生的数学探究意识
由于小学生对于数学知识还没有系统性的认识,在学习了一个新的数学理论知识或者数学公式概念之后,很容易在此过程中出现一些错误,这就要求教师将错误还给学生,让学生围绕错误进行深入探究,打开自己的思路,然后找到解答问题的正确方法。
例如,数学题中:将下列括号内写出正确的小数:5元3分=( )分。许多学生在看到这样的题目时,就会马上给出答案:5元3分=(53)分或者是5元3分=(530)分。……
