我们在初中平面几何的教学中,常常遇到解题难的问题。所谓难不外乎是分析难、定理的运用难、解题步骤及条件说明难。这些问题的解决是我们教师长期努力追求的目标,下面我就自己多年的教学经验来谈一下几何中常用的一种教学方法——大目标法。一、大目标法产生于几何学无论做任何事都要有目的,即所谓目标的追求,特别是几何问题 In the teaching of plane geometry in junior middle school, we often encounter the problem of difficult problem solving. The so-called difficulty is nothing more than the analysis difficult, the use of theorems difficult to explain the steps and conditions difficult to explain. The solution to these problems is the long-term goal that our teacher pursues. Here I will talk about my teaching experience of many years to talk about a kind of teaching method commonly used in geometry-big target method. First, the large target method produced in geometry, whether to do anything must have a purpose, the so-called pursuit of the goal, especially the geometric problems
