在物理课堂教学中，如何精心做好不同类型的演示实验，是物理课堂教学设计面临的主要问题。笔者根据多年的教学实践，浅谈几点做法和体会。1过渡性实验的设计有些演示实验所说明的现象和传授的知识与学生原有的认识水平有一个较大的台阶，不能被大多数学生所理解和接受。因此， In physics classroom teaching, how to do a good job of different types of demonstration experiments is a major problem facing physics classroom instructional design. Based on many years of teaching practice, the author discusses several practices and experiences. 1 Design of Transitional Experiments Some demonstration experiments demonstrate that the phenomena and the imparted knowledge have a greater level with the students’ original understanding level and cannot be understood and accepted by most students. therefore,
