学过物理的人都知道物理是实验科学,而实验又是培养学生各种能力的重要途径,并且物理教学中的实验教学能通过实验和观察使学生获得感性知识,并经过思维加工帮助学生形成物理概念。所以实验教学不仅是帮助学生建立物理概念、理解和掌握物理规律与原理的重要途径,还是培养学生观察能力、思维能力,形成学生良好科学探究精神和科学的实验方法的重要手段。更何况科学规范的实验教学可以激发学生浓厚的学习兴趣和科学探究的愿望,把物理课堂变成学习、求知和实践以及学生勇于探索的乐园。在我长达三十多年的初中物理教学生涯中,发现各种类型的物理实验,具体形象地展示了物理知识的形 People who have studied physics know that physics is experimental science, and experiments are important ways to cultivate students’ various abilities. Experiment teaching in physics teaching can make students acquire perceptual knowledge through experiments and observations, and help students to form through thought processing Physical concept. Therefore, experimental teaching is not only an important way to help students to establish the concept of physics, understand and master the laws and principles of physics, but also train students’ abilities of observation and thinking to form a good scientific exploration spirit and scientific experimental methods for students. Not to mention the scientific and standardized experimental teaching can stimulate students interest in learning and the desire for scientific inquiry, the physical classroom into learning, knowledge and practice, and students brave to explore paradise. In my thirty-year junior high school physics teaching career, I found various types of physical experiments that concretely demonstrated the shape of physical knowledge
