升入高中后,面对新的课程,新的知识,新的学习方法,很多学生多会感到无所适从,尤其是在高中立体几何方面颇感头疼.初中阶段我们接触的是一些简单的平面几何内容,学生在这一阶段并没有建立起比较强的空间感,所以学起立体几何来比较吃力.然而立体几何在历年的高考中有两到三道小题,必有一道大题.虽然分值比重不是特别大,但是起着举足轻重的作用.下面就如何学好立体几何谈几点建议.一、建立数学模型
Ascended to high school, the face of new courses, new knowledge, new learning methods, many students feel more at a loss, especially in high school three-dimensional geometry quite a headache.Middle school phase we are exposed to some simple plane geometry , Students at this stage did not establish a strong sense of space, so learn three-dimensional geometry to more difficult.However, three-dimensional geometry in the calendar year college entrance examination has two or three problems, there must be a big problem .Although the score The proportion is not particularly large, but plays a decisive role in the following on how to learn a few solid geometry talk a few suggestions First, the establishment of mathematical models
