为什么很多学生反映数学难学?笔者认为,很大一部分原因是我们的教学步入了误区,尤其是在解析几何教学中。解析几何在整个高中阶段起到一个衔接的作用,从这部分知识的特点来看,数形结合的思想贯穿整个内容,侧重点是研究用代数的方法解决几何的问题,但是很多时候却因为教师在教学过程中过于依赖数学方法,导致教学进入误区。本文就以解析几何教学为例,谈一谈高中数学教学中的几个常见误区,旨在帮助学生规避学习困境。1误区1:脱离定义定义是一类数学事件的抽象,反映了其最为本质
Why do many students reflect the math difficult? I believe that a large part of the reason is that our teaching has entered a misunderstanding, especially in analytic geometry teaching. Analytic geometry plays an important role in the whole high school. According to the characteristics of this part of knowledge, the idea of combination of numbers and shapes runs through the whole content. The emphasis is on solving the problem of geometry by means of algebra. But in many cases, Over-reliance on mathematical methods in the teaching process has led to the misunderstanding of teaching. This article takes analytic geometry teaching as an example to talk about several common errors in high school mathematics teaching so as to help students to avoid learning difficulties. 1 Mistake 1: Definition of definition of deviation from the definition of a class of mathematical abstraction, reflecting the most essential
