通过两个例题分析示范如何挖掘,发现有关移动的点,移动的线段,甚至移动的图形的一类数学问题中隐藏的“静”态的数量关系,尝试引导学生学会和善于发现挖掘隐藏在移动背后的“静”态的条件,以便建立“动”和“静”的联系.从而达到解决在移动状态中的相关数学问题。 Through two examples to analyze how to mine and find the relationship between the number of “static” states hidden in a class of mathematical problems such as moving points, moving segments, and even moving figures, we try to guide students to learn and be good at discovering and mining hidden The condition of “static” state behind the move, so as to establish the connection between “move” and “static”, so as to solve the related math problem in moving state.
