离子方程式的教学一直是高中化学阶段的教学重要内容之一,也是学生学习的难点之一.离子方程式应该如何去教,课本上给老师和学生提供了一种方法,也就是离子方程式的基本书写步骤,“写(写化学方程式)、拆(将反应物、产物拆成离子)、删(将方程式两边都有的离子、分子删除)、查(检查方程式两边的原子守恒、离子所带电荷数守恒)”的步骤去进行教学,然后通过学生的反复练习来达成教学目标.例如:教师以 The teaching of ion equation has always been one of the most important teaching topics in high school chemistry and also one of the most difficult points for students to learn.Individual equations should be taught in such a way that teachers and students can provide a basic textbook (Check the equations for the conservation of the atoms on both sides of the equation, the charges carried by the ions Number of conservation) "steps to teaching, and then through the practice of students to achieve teaching goals.For example: teachers to
