《数学课程标准》指出:“学生的数学学习内容应当是现实的,有意义的,富有挑战性的,这些内容要有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动.”在初中数学教学中恰当地引入数学实验有助于学生既长知识,又长能力.一、数学实验有助于学生加深对概念的理解在平时的教学中,我们经常会发现一些学生对数学概念的本质属性认识不够,似懂非懂,有时是知其然而不知其所以然.这种情况的出 The Mathematics Curriculum Standard states: “The mathematics content of students should be realistic, meaningful and challenging, and should be conducive to students’ initiative in mathematics such as observation, experiment, speculation, verification, reasoning and communication Activities. ”The appropriate introduction of mathematical experiments in junior high school mathematics teaching helps students have both long-term knowledge and long-term ability." Mathematical experiments help students to deepen their understanding of concepts In normal teaching, we often find some Students do not have enough understanding of the essential properties of mathematical concepts, understand it or not, sometimes know it but do not know why.
