初中物理教学是一项科学,更是一项艺术,尤其是存在多种不可控因素的实验过程中,面对不时出现的失误,教师是推倒重来,还是采用教学机智巧妙化解,这实际上是对教师生成能力的一种考验。本文结合教学实践中的具体案例指出,实验中的失误不可怕,只要教师能够因势利导、随机应变,就能将错就错、妙笔生花。 Junior high school physics teaching is a science, it is an art, especially in the existence of a variety of uncontrollable factors in the experimental process, in the face of the mistakes that occur from time to time, teachers are reinventing themselves, or clever use of teaching clever solution, which in fact It is a test of teacher’s ability to generate. In this paper, teaching practice in the specific case that the mistakes in the experiment is not terrible, as long as the teachers can make the best use of circumstances, to adapt to circumstances, we can make the mistake, wonderful flower.
