电化学知识是中学化学重要基础理论之一,也是近年来高考中的热点问题,涉及电化学知识的考题屡见不鲜.从历年高考情况来看,学生解答电化学类考题时得分率并不理想,通过对学生答题情况的调查统计发现,不能正确写出“电极反应方程式”是制约学生顺利求解电化学类问题的主要瓶颈.因此针对学生“电极反应方程式”书写中存在的典型问题,结合课堂教学实践,提出高中化学“电极反应方程式”的教学策略与思考.一、回归基本原理,理解反应实质 Electrochemical knowledge is one of the important basic theory of chemistry in high school, but also hot topics in college entrance examination in recent years, electrochemical knowledge test questions are common.From the calendar year college entrance examination situation, students answer the electrochemical test questions when the score is not satisfactory, through According to the investigation and statistics of students ’answers, we can not write “Electrode Reaction Equation” correctly, which is the main bottleneck that restricts the students to solve electrochemical problems smoothly.Therefore, according to the typical problems in students’ writing of “Electrode Reaction Equation” Combined with classroom teaching practice, proposed high school chemistry “Electrode reaction equation ” teaching strategies and thinking.A, return to the basic principles, to understand the nature of the reaction
