对于学生的发展来说,仅有基础知识与基本技能是不够的,学生还要掌握基本的数学方法,有数学思想,还要经历、体验数学活动,获得基本的数学活动经验。以《梯形的面积》的教学实践为例,文章探讨如何在小学数学教学中落实“四基”教学:第一,知识引入,激活学生已有的知识经验;第二,知识探究,引导学生数学化思考;第三,回顾反思,让学生通过提炼方法积累活动经验;第四,知识运用,让学生领会思想方法的应用价值。
For the development of students, only basic knowledge and basic skills are not enough. Students also need to master the basic mathematical methods, have mathematical thinking, experience, experience mathematical activities, and acquire basic mathematical experience. Taking “trapezoid area” teaching practice as an example, this article discusses how to implement “four bases” teaching in elementary mathematics teaching: first, knowledge introduction, activation of students’ existing knowledge experience; secondly, knowledge exploration and guidance Students think mathematically; thirdly, retrospecting and reflections, allowing students to accumulate activity experience through refining methods; fourthly, applying knowledge so that students can understand the value of applying thought and methods.
