伴随着新课标改革的大趋势,氧化还原反应称为等级考试的必考知识点,并且,其命题趋势更加注重实践,以考查社会问题或者生活中的典型例题为原型.因此,教师必须掌握一套科学的教学方法,使得学生不仅能够理解理论知识,还能够熟练运用原理解决有关氧化还原反应的题目.对此,笔者有以下几点教学体会:1夯实基础建立体系1)明确概念在化学学习的初始阶段,由于氧化还原反应被限
With the general trend of the new curriculum reform, the redox reaction is called the necessary examination point for the graded exam, and its proposition trend is more focused on practice. It is based on examining social issues or typical examples in life. Therefore, teachers must master A set of scientific teaching methods enables students not only to understand theoretical knowledge, but also to skillfully apply principles to solve problems relating to redox reactions. In this regard, the author has the following teaching experience: 1 to lay a solid foundation to establish a system 1) to define concepts in chemistry In the initial stage of learning, the oxidation-reduction reaction is limited
