氧化还原反应的概念和理论是贯穿无机化学的一条主线,对于学习元素及其化合物的知识具有非常重要的指导作用,也是化学教学的重点和难点。能否正确书写氧化还原反应方程式,充分体现了学生综合能力的高低,因此氧化还原反应成为各类考试的热点。而学生的答题情况往往又不尽如人意,在教学实践中,我们仔细分析了学生出现的错误,并与学生进行了交流,将其错误的原因和应对策略归纳如下。 The concept and theory of redox reaction is a mainstay that runs through inorganic chemistry. It plays a very important guiding role in learning the knowledge of elements and their compounds, and is also a key and difficult point in chemistry teaching. Can correctly write the redox reaction equation, fully reflects the level of comprehensive ability of students, so the redox reaction has become a hot spot for all kinds of exams. In the teaching practice, we carefully analyzed the students’ mistakes and communicated with the students. The causes and strategies of their mistakes are summarized as follows.
