电化学知识的教与学重在概念清晰,了解原理.弄清电极反应中电子和离子的流向,注意不同装置的联系和区别,不断提高运用和创新电化学知识的学习能力.如何突破难点而提高学习效果,是教师不断探究的课题,也是学生需努力思考的问题,在电化学知识的教学过程中,对于易混淆的一些慨念,笔者作了化解问题的实践,现就电化学反应原理和电子的流向问题说说自己的教学体会. Electrochemical knowledge of teaching and learning in a clear concept, understand the principle. Electrons and ions to clarify the flow of ions in the reaction, pay attention to the connection between different devices and differences, and constantly improve the use and innovation of electrochemical knowledge learning. How to break through the difficulties Improve the learning effect, the teacher is constantly exploring the issue, but also students need to think hard questions, in the electrochemical knowledge teaching process, confused for some of the ideas, the author made to resolve the problem of practice, is the electrochemical reaction principle And electronic flow to talk about their own teaching experience.
