摘　　要：结合结构化学课程中分子对称性知识点的教学,自主设计和开发了分子点群虚拟仿真实验(PGVL)平台,帮助学生深入认识理解分子对称性知识的重点和难点。该仿真实验采用Web技术构建,支持分子模型的显示和互动,使学生可以完成分子的各种对称操作、指出分子结构中的对称元素、推导分子点群及认识分子结构和性质之间的关系。PGVL在分子对称性教学中的应用,不仅完善了结构化学分子模型实践教学体系,而且提升了学生对结构化学课程的学习兴趣,丰富了结构化学实践教学内容,取得了良好的教学效果。Herein the construction and practice of molecular point group virtual laboratory(PGVL)is reported in molecule symmetry part of structural chemistry course,which is used to help students deeply understand and master the research methods and basic knowledge of molecular symmetry.The PGVL simulation experiment is constructed by web technology and supports the display and interaction of molecular models.Students could complete various symmetrical operations of molecules,point out symmetrical elements in molecular structure,deduce molecular point groups,and understand the relationship between molecular structure and properties.The application of PGVL platform in molecular symmetry could not only improve the practical teaching of molecular symmetry of structural chemistry,but also encourage students’interests in this field.PGVL enriches the teaching system in molecular symmetry of structural chemistry and achieves good teaching effect.
