演示实验是物理教学的重要组成部分,许多物理概念、规律的教学都是通过演示实验来完成.在新课标准中,学生学习兴趣的激发、观察能力的形成、实验能力的培养,都离不开教师成功地演示实验.学生探究能力形成、实验方法领悟和对实验现象的分析能力形成都与演示实验取得的效应有关.因此,成功地做好演示实 Demonstration experiment is an important part of physics teaching, many of the physical concepts and laws of teaching are completed through demonstration experiments.In the new class standards, students' interest in learning, the formation of observation ability, the cultivation of experimental ability, all from the Open teachers successfully demonstrated the experiment.The formation of students' ability of inquiry, the comprehension of experimental methods and the formation of analytical ability of experimental phenomena are all related to the effects of demonstration experiments.Therefore,
