一、问题的提出化学计算是学生要掌握的基本技能之一,它可以使学生从量的角度来理解物质及其变化规律。学生在学习中易解错题是教学过程中普遍存在的问题,原因除了学生对化学基本知识缺乏深刻理解外,主要是没有掌握解题的策略与技巧,不能适应试题的迁移和变化。如何在化学计算题的复习中帮助学生弄清化学概念,掌握解题的策略与技巧,是化学计算题复习的关键。二、实施的办法和途径1.弄清概念,灵活运用
First, the issue put forward Chemical calculation is one of the basic skills students need to grasp, it allows students to understand the material and its changing rules from a quantitative point of view. Students easily solve the problem of learning problems in the teaching process is a common problem, in addition to the students lack of basic knowledge of chemistry, a deep understanding of the main problem-solving strategies and techniques are not master, can not adapt to the migration and change of questions. How to help students to understand the chemical concepts and master the strategies and techniques of solving problems in the review of chemical calculation is the key to the review of chemical calculation problems. Second, the implementation of ways and means 1. To clarify the concept of flexible use
