1.引言1911年,盖革和马斯登在卢瑟福的指导下完成了著名的口粒子散射实验,卢瑟福从实验结果中提出了原子核式结构模型,由此开创了原子核物理学的新领域.α粒子散射作为一个近代物理的经典实验,是高中物理教材重点介绍的内容.在教学中,引导学生运用科学的思维去正确分析实验现象,认识原子的核式结构模型,学习物理学研究问题的科学方法,同时获得积极的情感体验是我们教学的重要目标.然而,由于中学没有条件开展此类实验,教师常常采用挂图和板书相结合的方式呈现实验现象,向学生灌输静态的物理事实,这恰恰导
1. Introduction In 1911, Geiger and Marsden completed the famous oral particle scattering experiment under the guidance of Rutherford, and Rutherford proposed a model of atomic nucleus structure from the experimental results, thus opening up the nucleus of nuclear physics. New area.α particle scattering as a classic experiment of modern physics, is the focus of high school physics teaching material. In teaching, guide students to use scientific thinking to correctly analyze experimental phenomena, to understand the nuclear structure model of atoms, learning physics Studying the scientific method of the problem and obtaining a positive emotional experience at the same time is an important goal of our teaching. However, because middle schools do not have the conditions to carry out such experiments, teachers often use wall charts and board books to present experimental phenomena and instill static physics in students. In fact, this leads
