“不积跬步,无以至千里;不积小流,无以成江海。”任何事物的发展变化都是从微小的积累开始。微小的改进可以带来意想不到的收获,微小的疏忽也会造成无法弥补的缺失。在全国苏教版小学数学教材第五届优秀课评比暨课堂教学观摩活动中,我看到了执教教师通过细节的改进闪现出的智慧火花,也有因为细节的失误而带来教学的遗憾。 “Accumulate without steps, without a trace; not plot a small stream, into Jianghai. ” The development of any change is from the beginning of a small accumulation. Slight improvements can bring unexpected results, minor negligence can also cause irreparable loss. In the national Jiangsu Education Primary School mathematics textbooks fifth excellent class evaluation and classroom teaching activities, I saw the wisdom of teachers through the improvement of the details of the flash of wisdom, but also because of the details of mistakes and bring the teaching of regret.
