论文部分内容阅读
《平面向量》是新编高中数学教材中新增的一章内容,对我们教师来说大多数是几年、十几年甚至是几十年前学过的内容,现在要教这部分知识就有一个再学习、再理解的过程,从而达到能驾驭的程度,现将自己对这章学习的体会和思考介绍给大家。1.搞好概念教学本章的内容是以向量的概念为理论基础,向量的运算为工具,向量的应用为目的编排的,平面向量这章概念多,只有在正确理解了概念基础上,才能真正学好这章知识,概念教学既是本章重点,又是本章难点。(1)注意从生活、生产实例中抽象出概念
“Plane vector” is a new chapter in the new high school mathematics textbook content for most of our teachers is a few years, a dozen years or even decades ago learned content, to teach this part of knowledge There is a process of re-learning and understanding, so as to achieve a level of mastery. Now we introduce ourselves to this chapter’s experiences and thoughts. 1. Improve the concept of teaching The content of this chapter is based on the concept of vector as the theoretical basis for the operation of vector computing tools, vector for the purpose of the layout, the concept of plane vector and more, only correctly understood the concept, based on the real Learn this chapter knowledge, concept teaching is not only the focus of this chapter, but also the difficulty of this chapter. (1) pay attention to abstract concepts from life and production examples
