“同课异构”是一种有效的教研方式,尤其是同课异构中的实验创新,为课堂教学奠定了扎实的基础.本文通过比较同课异构中实验创新的共性与个性,即实验的变通性,实验的求异性,实验的针对性,实验的改进性,实验的廉价性等,旨在探究创新实验的思路与方法,学习借鉴创新实验的策略与技巧,凸显中学物理课堂教学的灵魂. “Lesson heterogeneous ” is an effective way of teaching and research, especially experimental innovation in the same class heterogeneous, laying a solid foundation for classroom teaching.By comparing the commonality and individuality of experimental innovation in the same class heterogeneous , That is, the experimental adaptability, the experiment’s anisotropy, the experiment’s pertinence, the experiment’s improvement, the experiment’s cheapness and so on aims to explore the ideas and methods of innovative experiments, learn from the innovative experiment’s strategies and techniques, highlights the high school physics The soul of classroom teaching.
