物理教学中的演示实验和科学实验不尽相同,演示实验是在特定的环境与条件下,由教师做给学生看的示范实验。演示实验是最直观的教学手段,在物理教学中具有重要的意义。它对于传授物理基础知识,培养学生的思维能力和锤炼学生的科学素养都有不可忽视的作用。然而,要使其在教学中发挥好这些作用并非易事,教师必须精心设计和不断地改进演示实验,这是一项创造性的劳动,它对于改进教学方法,提高教学质量,都是一项十分有意义的工作。实践证明,学生喜欢上有演示实验的物理课。演示是展现物理教学魅力的有效手段,它有化枯燥为生动、化抽象为具体、化平淡为神奇的功能。在激发兴趣、建立概念、验证规律、培养科学的思维方法等方面起着十分重要的引导作用。这就要求教师在做演示实验时,既要准确直观、现象明显,以求最佳效果,又要注意充分调动学生的多种感官 The demonstration experiment and the scientific experiment in the physics teaching are not the same. The demonstration experiment is a demonstration experiment to be seen by the teachers under the specific environment and conditions. Demonstration experiment is the most intuitive teaching method, which is of great significance in physics teaching. It can impart the basic knowledge of physics, cultivate the thinking ability of students and improve students’ scientific literacy. However, to make these roles play a role in teaching is not easy. Teachers must carefully design and continuously improve the demonstration experiments. This is a creative work which is very important to improve teaching methods and improve teaching quality Meaningful work. Practice has proved that students like to have a demonstration of physics experiments. Demonstration is an effective means to show the charm of physics teaching. It has the function of turning the dullness into vividness, the abstracting into the concreteness and the plainness into the magical function. It plays a very important guiding role in stimulating the interest, establishing the concept, verifying the law and cultivating the scientific thinking method. This requires teachers to do demonstration experiments, it is necessary to accurately and intuitively, the phenomenon was obvious, in order to achieve the best results, but also pay attention to fully mobilize the students a variety of senses
