初中科学是一门以实验为基础的学科,其实践性和理论性都很强,很多知识需要在实验背景下自然生成。尤其是现在倡导的新课改中,实验教学在课程教学中有其独特的地位和作用。所以,教师应深入研究如何优化课堂实验教学,提高教学成效,打造高效课堂。就有关实验改进课例《熔化和凝固》的一次课前实验准备和三次借班磨课来谈谈实验改进对实验教学的重要性。
Junior high school science is an experiment-based discipline, its practicality and theoretical are very strong, a lot of knowledge needs to be naturally generated in the experimental context. Especially in the new curriculum reform now advocated, experimental teaching has its unique position and function in the course teaching. Therefore, teachers should study in depth how to optimize classroom teaching, improve teaching effectiveness and create efficient classroom. We will talk about the importance of experimental improvement to experimental teaching on the basis of one pre-experiment preparation and three borrowing lessons about the experimental improvement lesson “Melting and Solidification.”
