我在一堂常识课上是这样引导大班幼儿初步形成弹性概念的: 我首先从幼儿常接触的松紧带入手。上课时,我双手扯起一条松紧带,边拉边问:“这是什么?”幼儿齐答:“这是松紧带。”为了让幼儿观察得更清楚些,我把白色的松紧带挂在黑板上,然后用力往下拉,问幼儿:“老师用力拉它,它就怎样了?”幼儿纷纷举手回答,有的说松紧带变长了,有的说松紧带变细了, In a common sense class, I guided the children in primary schools to initially form the concept of flexibility: I first started with the elastic bands that my child often touched. When I was in class, I pulled an elastic with my hands and asked for a pull. “What’s this?” Toddlers answered: “This is an elastic band.” To make the child’s observation clearer, I hung the white elastic band on the blackboard, Then pull hard and asked young children: “The teacher hard to pull it, what is it?” Young children have raised their hands to answer, and some said the elastic belt longer, and some said the elastic thinning,
