摘要 配合物、配位键是高中化学选择性必修课程"物质结构与性质"模块的重要知识。本节课采用"项目式教学"的方式,巩固配位键和配合物形成的结构基础,学生们在检验补铁药片中铁元素化合价的系列化学实验过程中,初步建立配位平衡及其影响因素的概念,体会配合物的使用价值,从而提升学生对配位键和配合物的认识。 Coordination compounds and coordination bonds are important knowledge of the high school chemical selectivity compulsory course "Material Structure and Properties". This lesson adopted the "project-based teaching" method. In the process of a series of chemical experiments of inspection of iron element valence in iron tablets, the students reviewed the formation of coordination bonds and coordination compounds. It helped establishing the concept and affecting factors of coordination equilibrium. Then students realized the use value of coordination compounds. The students improved the understanding of coordination bonds and coordination compounds.
