摘要
结构化学分子对称性章节中群的表示和应用部分的相关知识点抽象,晦涩难懂,学生学习困难,而这部分知识又是联系后续章节以及其他专业课相关知识的重要基础。针对这种情况,提出以学生为主体,教师引导学生经历知识的形成过程。通过一系列教学策略,包括:数学推导图形化,经历抽象知识的形成过程,绘制概念图,抽象知识的具象应用等,充分发挥学生的主观能动性让教与学的难点不再是难点,而是变成课堂主动学习的亮点。
The representation and application of molecular point groups in structural chemistry are abstract and difficult to understand,making it difficult for students to learn.However,this knowledge is an important foundation for subsequent chapters.In response to this situation,we propose a student-centered approach with teachers guiding students through the process of knowledge formation.Through a series of teaching strategies,including visualizing mathematical deduction,deducing the evolution process of knowledge,drawing concept maps,and applying abstract knowledge concretely,teaching and learning difficulties are no longer difficult,but become bright spots for active classroom learning by fully unleashing students’subjective initiative.
