“两角差的余弦公式”是普通高中数学教学的一个经典课例,本文结合学校的同课异构活动,提出了三点建议:一是公式教学要重视过程;二是公式教学要顺其自然;三是公式教学更要关注后半段.并结合自身教学经验给出了相应的实施办法.一、公式教学要重视过程新课标的一大特点是提出了“过程与方法”的目标.经过几年的实践,一线教师基本都已形成了共识,那就是公式教学一定要关注知识发生、发展和形成的过程.可迫于应试的压力,对教材理解不够深刻等多种原因,很
“The cosine formula of difference of two angles ” is a classical lesson in ordinary high school mathematics teaching. This text has put forward three suggestions in the light of the same course heterogeneous activity of the school: One is the teaching of formula should pay attention to the course; The other is the teaching of formula Let it be natural; Third, the formula teaching should pay more attention to the second half, combined with their own teaching experience to give the corresponding implementation methods. First, the formula teaching should pay attention to the process of a new curriculum standard is characterized by the “process and methods ”After several years of practice, front-line teachers have basically reached a consensus that formula teaching must pay attention to the occurrence, development and formation of knowledge process can be forced by the pressure of the examination, the teaching material is not deep enough and many other Reason, it is
