化学是在原子、分子水平上研究物质的组成、结构、性质、变化及其应用的一门基础自然科学,是从微观的角度认识物质及其变化的科学。微粒观是指微观知识或信息在大脑中记载和呈现的方式,主要是指微粒,如原子、分子、离子等的运动和相互作用。微粒观的构建既是高中化学教学的重要任务,也是提高学生化学学科素养的有效手段。氧化还原反应和离子反应是高中化学教学内容的两个重要的基本概念,笔者在教学中发现,学生对于这两 Chemistry is a basic science that studies the composition, structure, property, change and application of matter at the atomic and molecular levels. It is a science that recognizes matter and its changes from a micro perspective. Particle concept refers to the micro-knowledge or information recorded and presented in the brain, mainly refers to the movement of particles, such as atoms, molecules, ions and interactions. The construction of particle concept is not only the important task of high school chemistry teaching, but also an effective way to improve students’ chemistry discipline quality. Redox reaction and ion reaction of high school chemistry teaching content is two important basic concepts, the author found in teaching, students for these two
