摘要
采用板书与多媒体技术、课堂讲授与学生讨论相结合的教学方法,从氧化还原反应的实质角度介绍了原电池的工作原理,使学生学会书写电极反应式和电池总反应,对原电池的形成条件有更完整的认识。指导学生了解生活中电池使用原理、金属腐蚀和防护,能根据反应设计简单的原电池,研究探索发明新电池有重要意义。
The teaching method of the writing on the blackboard and multimedia technology, moreover, and the combination of teaching and students＇ in the classroom were discussed. The working principle of primary batteries from the redox reactions was introduced, making students enable to learn the electrode reaction and writing the electrochemical reaction. A complete understanding of the formation conditions of the original battery. The students were guided to understanding the life of the battery principle and metal corrosion and protection. According to the reaction of primary battery simple design, the important significance of invention a new battery research has.
