基于“做学教合一”理念的中职数学活力课堂案例研究——以“直线与圆的位置关系”为例

On the Dynamic Mathematics Class in Secondary Vocational Schools Based on the Concept of the "Integration of Practice, Learning and Teaching" : A case study

熟练掌握并运用数形结合思想解题是数学基础薄弱、思维能力不强的中职学生感到比较困难的内容之一。本文以“直线与圆的位置关系”为例,通过学生在自主做实验的过程中探究性地“学”,与教师的引导性地“教”产生合力,实现知识能力与核心素养的有机内化,凸显出“做学教合一”理念下课堂的效益,为构建中职数学活力课堂提供有益的参考。

It is difficult for secondary vocational school students who have weak mathematical foundation and weak thinking ability to master and use the idea of combination of numbers and shapes to solve problems.This paper takes"The position relationship between the straight line and the circle"as an example to realize the organic internalization of knowledge ability and core literacy through the students'inquiry"learning"in the process of independent experiment and the teachers'guidance"teaching"to produce a joint force.It highlights the classroom efficiency under the concept of"the integration of practice,learning and teaching",and provides a useful reference for the construction of the dynamic Mathematics class in secondary vocational schools.
