精准定位 顺理助学:提升第一学段学生运算能力

Accurate Positioning and Assisting in Learning in Accordance With the Law:Improving the Computational Ability of First Learning Stage Students

在数学学习过程中,掌握运算规则并能准确计算是小学生的关键能力之一。文章基于实际教学经验,对小学生常见的计算错误进行解构,以精确定位问题所在,并顺应学理,提出有效提升小学低年级学生计算思维深度的策略:调动经验,帮助儿童找感觉;借助模型,引导学生寻方法;必要训练,引导学生成能力。并在此基础上进一步探讨提升路径:结构化组织,促成学习序列的融合;多途径合力,丰富学习资源的开发。旨在拓展学生运算思维的广度,助力第一学段学生计算能力的全面发展。

In the process of learning mathematics,mastering the rules of operation and being able to accurately calculate is one of the key abilities for students.Based on practical teaching experience,this paper deconstructs common calculation errors among students,to accurately locate the problems,and explore effective strategies to enhance the depth of calculation thinking among lower grade primary school students in accordance with academic principles:helping children find approaches by mobilizing experience;guiding students to find methods by using models;guiding students to develop their abilities with necessary training.Based on this the improvement path is further explored:structured organization promotes the integration of learning sequences;Multi channel collaboration enriches the development of learning resources,which expands the breadth of students’computational thinking and assisting in their comprehensive development of computational abilities in the first learning stage in primary schools.
