小学数学问题链构建的策略探究--以人教版小学数学“两位数乘两位数”为例

Research on the Strategy of Constructing the Chain of Elementary School Mathematics Problems--Taking"Two-Digit Multiplication by Two-Digit Number"as an Example in PEP Primary School Mathematics

问题是数学的心脏,数学是思维的体操。在数学课堂,引导学生对问题进行深入探究,能够有效促进学生思维的发展,实现深度学习、发展核心素养。问题的深入探究,离不开问题链的构建。文章在厘清数学问题链内涵和意义的基础上,归纳出问题链具有关联性、整合性、开放性、逻辑性、梯度性、聚合性、探究性等特点,并从问题链的切入口、主干、形式等方面提出构建小学数学问题链策略,以供大家借鉴和思考。

The problem is the heart of mathematics,mathematics is the gymnastics of thinking.In mathematics class,guiding students to conduct in depth exploration of problems can effectively promote the development of students'thinking,realize deep learning and develop core literacy.The exploration of the problem is inseparable from the construction of the problem chain.Articles in the chain of specified mathematical problems based on the connotation and significance,concludes the problems chain is relevant,integrated,open,logicality,polymerized and exploratory,and from the chain of the introduction,the trunk,form the elementary school mathematics problem chain strategy is proposed,to provide reference for the people and thinking.
