近几年各地中考试题中动点是考试的热点,如何在动点问题中探究出解题规律,形成学生的个人数学素养,需要一线教师不断的钻研和探究,在“动”、“静”中巧妙地转换,即抓住问题的本质是:不动,从而抓住了题目中的数量关系构造相对应的方程解决问题.在平时教学汇总不断塑造学生的视图能力,模型意识,充分把握动点问题的规律,就会在中考中披荆斩棘,从学生的长远发展来看,也会形成独特的数学思维能力.本文重点探究动态几何中的第一种基本类型——动点问题.
In recent years, the moving points in various middle school examination questions are the hot spots of examinations. How to solve the problem-solving rules in the moving point question and form the students’ personal mathematics literacy requires the continuous study and exploration of the front line teachers in the “movement” and the The “quiet” ingeniously shifts, that is to grasp the essence of the problem is: not moving, thus seizing the number of problems in the subject to construct the corresponding equations to solve the problem. In the usual teaching summary continuously shaping the students’ view ability, model awareness In order to fully grasp the laws of the dynamic point problem, we will be overwhelmed by the difficulties in the midterm exam. From the perspective of students’ long-term development, we will also develop unique mathematical thinking skills. This article focuses on the first basic type in dynamic geometry - the dynamic point problem. .
