初中化学课程标准明确指出,化学计算包括利用相对原子质量、相对分子质量进行物质组成的简单计算;能正确书写简单的化学反应方程式,并进行简单的计算;能进行溶质质量分数的简单计算。怎样的教学策略才能提高学生的化学计算能力呢?一、注重化学概念的教学,加强化学用语的训练,为化学计算夯实基础首先涉及初中化学计算的一些重要概念,在形成时应尽可能通过实验或其他具体事物分析、概括导出;其次,注 Junior high school chemistry curriculum standards clearly pointed out that chemical calculations include the use of relative atomic mass, relative molecular mass of the simple composition of matter; can write a simple chemical reaction equations and simple calculations; solute mass fraction can be simply calculated. First, pay attention to the teaching of chemistry, to strengthen the training of chemical terms, to lay a solid foundation for chemical calculation First of all, involving some of the important concepts of junior high school chemistry calculation, as far as possible in the formation of the experiment Or other specific analysis, general derivation; Second, note
