探究氧化还原反应的有效教学向来是高中教师教学研究的重点,也是一个在教学中教师倍感困惑和棘手的实践问题。作为化学模块必修Ⅰ中的教学重点和难点,以往过分的知识本位和海量的题型训练的教学方式,给学生带来巨大的心理困惑和种种不适。氧化还原反应概念及其规律是人类在认识许许多多化学反应及反应途径、过程中逐渐提炼出来的对化学反应的本质认识,是人类认识化学变化的重要视角和重要手段。高中学生从得氧失氧观点建
To explore the effective teaching of redox reaction has always been the focus of high school teachers teaching and research, but also a teacher in the teaching of perplexity and thorny practical problems. As a key and difficult teaching point in Chemical Module Compulsory Ⅰ, past excessive knowledge-based and massive teaching methods of the subject type training bring great psychological confusion and discomfort to the students. The concept of redox reaction and its regulation are the essences of chemical reactions gradually extracted by human beings in understanding many chemical reactions and reaction ways. They are important perspectives and important means for human understanding of chemical changes. High school students from Oxygen and oxygen point of view
