论文部分内容阅读
拜读完《小学教学》(数学版)2013年第11期石永红老师的《对利用天平平衡的道理解方程的思考》一文后,禁不住掩卷反思。其实,在课堂教学中自己也经历过这样的事情,但是,没有从实质上去思考、去把握。相信正是由于石老师对问题的深入思考,抓住了问题的本质,才催生了文章末尾的精彩感悟。
After reading the article “Primary School Teaching” (Mathematics Edition) 2013, No. 11 Shi Yonghong’s “Reflections on Equations That Balance the Balance of Roads by Using Balances,” we can not help but conceal them. In fact, in the classroom teaching themselves have experienced such a thing, however, did not think in essence, to grasp. I believe it is precisely because of Shi teachers in-depth thinking on the issue, to seize the essence of the problem, it gave birth to the wonderful insights at the end of the article.
