物理学是一门以观察和实验为基础的学科.初中阶段是学生学习物理知识的启蒙阶段,学好初中物理知识,掌握初中物理学习的基本方法和技能,对学生今后的工作和学习尤为重要.实验,在物理教学中有利于传授物理知识、激发学生学习兴趣、培养学生动手动脑的能力,有助于学生树立辩证唯物主义的世界观,是研究物理问题、进行物理教学的直观的教学手段,是对学生进行素质教育,培养、拓展学生综合能力的切实有效的好方法.但是.实验教学的方法和目的又决定了实验教与学的效果.在目前以考试分数高低来衡量教学效果优劣的情况 Physics is a discipline based on observation and experimentation. The junior high school stage is an enlightenment stage for students to learn physics knowledge. It is important for students to work and learn in the future by learning basic physics knowledge and mastering the basic methods and skills of junior high school physics learning. Experiments, in physics teaching, are conducive to imparting physical knowledge, stimulate students’ interest in learning, and develop students’ ability to use hands-on brains. They help students establish a dialectical materialist world view. They are intuitive teaching methods for studying physics problems and teaching physics. It is an effective and effective method for students to carry out quality education and to develop and expand students’ comprehensive abilities. However, the method and purpose of experimental teaching determine the effectiveness of experimental teaching and learning. At present, the level of test scores is used to measure the quality of teaching effectiveness. Happening
