摘 要:在配合物教学中,以“组成结构决定性质,性质决定用途”的化学观念为统领,将配合物的组成和结构特点、性质、用途等相关知识与认识物质的一般思路有机整合,实现了单元知识的整体架构。选取学生熟悉的关联性素材,创设启发性问题链,为学生的认知发展搭建台阶,利用“宏观-微观-符号”三重表征开展学生活动,引导学生从宏微结合的视角分析物质的性质和变化,打通了知识间的纵横联系,促进知识结构化、认识思路结构化,培养学生的结构化思维及学科核心素养。In the teaching of complexes,guided by the big ideas of“composition and structure determine properties,properties determine purposes”,the relevant knowledge of the composition,structural characteristics,properties,and uses of complexes is organically integrated with the general idea of understanding matter,and the overall structure of unit knowledge is realized.Select related materials familiar to students,create a chain of enlightening questions,build a step for students'cognitive development,use the“macro-micro-symbol”triple representation to carry out student activities,guide students to analyze the properties and changes of matter from the perspective of macro and micro combination,open up the vertical and horizontal connections between knowledge,promote the structuring of knowledge and cognitive ideas,and cultivate students'structured thinking and discipline core literacy.
