小时候,看父亲挖圆坑,先将一根绳钉在地面上,然后拉直转一圈,一个圆就出现了,当时觉得很神奇.上学后,才知道这是圆的定义:平面上动点到定点的距离等于定长的点的轨迹.原来,生活中蕴藏着数学,而数学能服务于生活.长大后,作为一名数学老师,经常想如果数学课也能设计一些实验,改变数学教学仅仅依赖一支粉笔、一块黑板和教师单向传输知识的模式,或许学生学习数学的兴趣会更高.好的数学实验加深了学生在教学过程中的参与 When I was a child, I watched my father dig a round pit and first nailed a rope to the ground. Then he straightened and turned a circle. A circle appeared. It was amazing at that time. After school, he learned that this was a circle definition: moving on a plane The distance from the fixed point to the fixed point is equal to the trajectory of the fixed point. Originally, life contained mathematics, and mathematics was able to serve life. When I grew up, as a math teacher, I often thought that if the math class can also design some experiments, change The mathematics teaching only depends on a chalk, a blackboard and the teacher’s mode of one-way transmission of knowledge. Perhaps students’ interest in learning mathematics will be higher. A good mathematics experiment deepens students’ participation in the teaching process.
