一、引言上个世纪初,卢瑟福从α粒子的散射实验中提出了原子的核式结构模型,并由此开辟了原子核物理的新领域,其中α粒子散射实验也成为了后人学习原子结构的“入门”.高中物理教材中,α粒子散射实验是重点介绍的内容,但由于中学一般较难开展此类实验,教师常采用看图讲“实验”的方式,向学生灌输“静态”的物理事实.但实际情况是这种呆板的教学方式往往导致学生被动地接受结论,机械地记忆. I. INTRODUCTION At the beginning of last century, Rutherford proposed the nuclear structure model of atomic from the scattering experiment of alpha particle, and thus opened up a new field of nuclear physics, in which the experiment of alpha particle scattering also became the later learned atom Structure “entry.” High school physics textbooks, alpha particle scattering experiment is focused on the content, but as secondary schools are generally more difficult to carry out such experiments, teachers often use to see the picture to say “experiment ” approach to students Inculcating the “static” physical facts, but the reality is that this inflexible approach to teaching often leads students to passively accept conclusions and memorize mechanically.
