《普通高中数学课程标准(实验)》中明确概念教学应该返璞归真,努力揭示数学概念、法则、结论的发展过程和本质。目前,概念形成过程的教学中出现了很多弊端,如以解题教学代替概念教学,导致概念教学根基的缺失。本文就问题链搭建平台,几何画板微整合促成概念动态生成进行实例研究,打造数学概念形成过程的教学模式,成为高中数学概念教学的有益补充。
The clear concept teaching in “Ordinary High School Mathematics Curriculum Standard” should be back to basics, trying hard to reveal the development process and essence of mathematical concepts, rules and conclusions. At present, there are many drawbacks in the teaching of the concept formation process, such as replacing the concept teaching with problem-solving teaching, which leads to the lack of the foundation of concept teaching. This paper builds a platform for the problem chain, micro-geometry sketchpad to promote the concept of dynamic generation of case studies to create a mathematical concept of the process of teaching the formation of the concept of high school mathematics teaching as a beneficial supplement.
