聚焦核心素养 凸显推理能力——《交换律》教学实践与思考

Focus on Core Literacy and Highlight Reasoning Ability——Teaching Practice and Thinking of《Exchange law》

在小学数学课堂教学中,学生推理能力的培养与核心素养的提升息息相关。借助《交换律》教学的主题实践,学生透过"不完全归纳法"的体验,经历了科学推理验证的全过程,使核心素养得到有效的落实,也提升了推理能力。教师应鼓励学生大胆猜想,引导学生认真观察、严谨思考,反复验证,发散求异,有效激发其探索欲望,为合情推理能力培养打下基础,提升学生核心素养。

in primary school mathematics classroom teaching,the cultivation of students’reasoning ability is closely related to the promotion of core literacy.With the help of the theme practice of the exchange law teaching,students have experienced the whole process of scientific reasoning verification through the experience of"incomplete induction",which effectively implemented the core literacy and improved the reasoning ability.Teachers should encourage students to guess boldly,guide them to observe carefully,think carefully,verify repeatedly,seek differences,effectively stimulate their desire for exploration,lay the foundation for the cultivation of reasoning ability,and improve the core quality.
