实现小学数学课堂教学的策略和形式是多种多样的,下面以《平行线》一课为例,谈谈有效教学的一些感悟。一、创设有效的教学情景情景之一:播放北京奥运会火炬点燃的时刻。师:你知道火种是怎么来的?(播放在奥林匹亚山上采集火种的场景)师:这火炬怎么就点燃了?(抽象出平行光线反射后相交的情形)师:这两条光线的位置关系是不一样的,指着相交的图形问:“这种位置关系叫什么呢?”生1:像叉子。生2:交叉线。
The strategies and forms to realize the elementary mathematics classroom teaching are various and varied. Take the lesson of “parallel lines” as an example to talk about some insights of effective teaching. First, create an effective teaching scenario One of the scenes: Beijing Olympic Games torch lit moment. Teacher: Do you know how the fire came from? (Playing the scene of the fire collection on Mount Olympia) Teacher: How did the torch ignite? (The abstract is the case where the parallel rays are reflected.) Teacher: The relationship between the two rays is Not the same, pointing to the intersection of the graphics Q: “What is the relationship between this place? ” Health 1: like a fork. Health 2: cross line.
