《数学新课程标准》要求培养学生在运动变化中的观察能力,建模能力,以及几何直观能力.于是在中考题型中,动态问题成了热点考题.动态问题主要包括动点,动线,动面三种运动类型,它主要以几何图形为载体,运动变化为主线,集多个知识点为一体,多种解题思想和方法为一体.这类题综合性强,能力要求高,它能全面考查学生的实践操作能力,空间想象能力以及分析问题和解决问题的能力.大多学生往往处理不到位,得分率较低,究其原
The new mathematics curriculum standards require students to observe the changes in the movement ability, modeling ability, as well as the ability of geometric intuition .Therefore in the test questions type, the dynamic problem has become a hot test questions.Dynamic problems include moving point, moving line, Dynamic surface of the three types of sports, which mainly geometry as the carrier, the main movement changes, set a number of knowledge points as a whole, a variety of ideas and methods for solving the problem of one of these questions comprehensive, demanding ability, it A comprehensive examination of students’ practical ability to operate, space imagination and ability to analyze and solve problems.Most students often do not handle, scoring rate is low, the original
