一、教材分析本节内容与生活联系较紧密,可以联系生活实际,使学生的认识更具体。本节内容在氧化还原反应学习之后,可以让学生用氧化还原反应的理论来指导元素化合物知识的学习,并且用元素化合物的知识来更深层次地理解氧化还原反应,为以后元素化合物知识的学习打下基础。教学难点:实验设计,Fe2+与Fe3+的性质和相互转化。教学重点:通过实验探究认识Fe2+与Fe3+的性质和转化。二、学情分析1.知识储备学生已经掌握了氧化还原反应和离子反应的理论知识,初步 First, textbook analysis This section content and life more closely, you can contact the actual life, so that students know more specific. In this section, after the study of redox reaction, students can use the theory of redox reaction to guide the study of the knowledge of elemental compounds, and further understand the redox reaction with the knowledge of elemental compounds, so that they can learn the knowledge of later elemental compounds basis. Teaching Difficulties: Experimental Design, Fe2 + and Fe3 + Properties and Mutual Conversion. Teaching focus: to understand the nature and transformation of Fe2 + and Fe3 + through experimental exploration. Second, the academic analysis 1. Knowledge Reserve Students have mastered the theoretical knowledge of the oxidation-reduction reaction and ion reaction, preliminary
