俗话说:“几何学叉叉角角,学生难学老师难教”.从目前的教学来看,这种现象越演越烈.很多学生对几何证明题,不知从哪下手,甚至部分学生知道了大致过程和结果,但叙述不清楚,理由不明了.对逻辑推理的过程几乎不会写,这样使大部分学生失去了学习数学的信心.因此,这是每个一线的数学教师急需解决的问题,要解决问题先要找到问题的症结所在,才能寻求有效的教学策略.
As the saying goes: “geometry fork angle, students difficult to learn the teacher difficult to teach.” From the current teaching point of view, this phenomenon becomes more and more intense. Many students on the geometric proof questions, I do not know where to start, or even part Students know the general process and results, but the narrative is not clear, the reason is unknown, the process of logical reasoning is almost not written, so that most students lose the confidence to learn mathematics.Therefore, this is every first-line math teacher in urgent need To solve the problem, to solve the problem first find the crux of the problem, in order to seek effective teaching strategies.
