数学课堂教学需要教师的精心设计,不仅仅是数学概念教学,还包括复习课教学或专题教学.高中数学有很多的碎片化重点知识,这与泛在数学学习知识完全不一样,诸如高中数学难点恒成立问题教学的解决策略、立体几何中的轨迹问题、向量解决策略问题等,都是数学教学的突破口.本文以恒成立教学解决策略为本,进行了课堂教学的设计,与大家交流.一、设计背景函数是整个高中数学知识体系的核心内容之一,而函数中的绝大多数问题最终归结为函数的性质以及函数思想在具体
Mathematics classroom teaching requires the careful design of teachers, not only the teaching of mathematics concepts, including the review of teaching or special teaching.School mathematics has a lot of focus on the fragmentation of knowledge, which is utterly different from ubiquitous mathematics learning knowledge, such as high school mathematics difficulties Constantly set up the problem of teaching strategies to solve the problem of trajectory in the three-dimensional geometry, vector to solve the problem of strategy, are the breakthrough of mathematics teaching.This article is based on the teaching strategy of constant established teaching solution, the classroom teaching design, to communicate with you. , The design background function is one of the core contents of the entire high school mathematics knowledge system, and the vast majority of the problems in the function are ultimately attributed to the nature of the function and the idea of the function in the concrete
