动点问题在中考中出现频率很高,占分比例大,同时难度也不小,不少学生感觉综合性太强,难以把握。通过多年的教学实践,总结出了研究图形明确条件,构建含t代入式、列出等量关系式,以及利用方程、函数式解决问题的四步法,效果十分不错。 Moving point problem in the examination frequency is high, accounting for a large proportion of the same time, difficulty is not small, many students feel too comprehensive, difficult to grasp. Through many years of teaching practice, it is concluded that the explicit conditions for the study of graphs, the construction of the four-step method of solving the problem involving the generation of t with the same amount of relations, and the use of equations and functions are quite good.
