摘要
以问题情境导入课堂,在解决具体问题中尝试归纳出物质含量测定的基本方法。让学生以小组合作的形式自主选择实验原理和实验试剂,搭建相应的实验装置,引导学生对自己的实验设计进行误差分析和改进。开放性的实验设计是提升学生化学核心素养的有效途径。
This paper introducd the problem situation into the classroom,and summarized the basic methods of substance content determination in solving specific problems,let the students choose the experimental principle and reagents independently in the form of group cooperation,built the corresponding experimental device,and guided the students to make error analysis and improvement on their own experimental designs.Open experimental design was an effective way to improve students’chemical core literacy.
