摘要

对称是自然界中常见的现象,在化学教育领域具有重要意义。然而,使用传统教科书,学生往往难以直观地理解三维分子的对称元素并识别点群。为了解决这一难题,我们将 SYVA 集成到 VMD 中,以准确确定分子点群。此外,我们还整理了分子点群材料,作为教育资源。该资源目前包括数百个独特的分子,并在不断扩展,以有效展示分子中的各种对称元素,帮助确定点群。在此资源的基础上,我们设计了一个以分子对称性为重点的教育活动。根据学生的反馈,利用 VMD 展示分子点群文件并直观地表示分子对称元素,有利于学生理解相关概念。该资源可作为对称性教学的重要工具,具有互动性、视觉吸引力和离线可访问性,可在不同时间和地点灵活使用。

Visualizing Symmetry: A Resource for Chemical Education with VMD and SYVA Programs

Visualizing Symmetry: A Resource for Chemical Education with VMD and SYVA Programs
Symmetry, a common occurrence in nature, holds significant importance in the realm of chemistry education. However, students often struggle to visualize the symmetry elements of three-dimensional molecules and identify point groups using traditional textbooks. In order to address this challenge, we integrated SYVA into VMD for accurate determination of molecular point groups. Additionally, we have organized molecular point group materials to serve as an educational resource. The resource currently includes hundreds of unique molecules, with continuous expansion, to effectively demonstrate various symmetry elements within molecules and aid in determining point groups. Expanding on this resource, we have designed an educational activity focused on molecular symmetry. According to student feedback, utilizing VMD to showcase molecular point group files and visually represent molecular symmetry elements is beneficial for students in comprehending related concepts. This resource can serve as a valuable tool for teaching symmetry, offering interactivity, visual appeal, and offline accessibility, allowing for flexible use across different times and locations.

期刊介绍: The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
