玻尔原子模型理论创造性地结合了普朗克的量子学说和卢瑟福的原子核概念,成功地解释了氢原子和类氢原子的结构和性质.但由于该理论模型背景知识的复杂性,一直以来都是高中原子物理部分的教学难点.本文对人教版“玻尔的原子模型”进行教学设计,以该模型提出的时代背景为出发点和主要线索,重点讲授玻尔模型所解决的关键科学问题和采用的开创性方法;引导学生深入理解和掌握该模型的提出过程和科学内涵,领悟科学探究方法.
Bohr’s atom model theory creatively combines Planck’s theory of quantum and Rutherford’s concept of nuclei. It successfully explained the structure and properties of hydrogen atoms and hydrogen-like atoms. However, due to the complexity of the background knowledge of the theoretical model, It has been the teaching difficulty of the atomic physics part of the high school. This article is teaching the teaching model of human “Bohr’s atom model ”. The background of the model put forward as the starting point and the main clue, focusing on teaching the Bohr model to solve Key scientific issues and groundbreaking methods adopted; guide students to understand and master the model’s proposed process and scientific connotation, and to understand the methods of scientific inquiry.
