摘要: 针对结构化学课程中晶体结构微观构型抽象、三维空间认知困难,以及传统教学资源展示形式受限、专业晶体可视化软件难以满足本科教学需求等问题,设计并开发了一款面向结构化学教学的典型晶体结构三维可视化微信小程序“晶典在线”。小程序收录金属、离子、共价、分子、混合键型五大典型晶体结构,集成三维模型展示、图层调控、模型切换、触控交互和晶体学信息查询等功能,可直观展示晶胞构型及其结构特征。依托微信平台,小程序具有免安装、跨终端运行和便捷访问等特点,可满足课前预习、课堂演示、课后巩固和实验教学等多场景应用需求。教学实践表明,该小程序能够有效增强晶体结构教学的直观性和交互性,有助于学生建立三维空间认知,为结构化学课程的数字化教学提供了一种轻量化、可推广的实践方案。

Abstract: To address the challenges in structural chemistry education, including the abstract nature of microscopic crystal configurations, difficulties in developing three-dimensional (3D) spatial cognition, the limited presentation formats of traditional teaching resources, and the inability of professional crystal visualization software to meet the needs of undergraduate teaching, a WeChat mini program named “Crystal Online” was designed and developed for the 3D visualization of typical crystal structures in structural chemistry instruction. The mini program includes five representative categories of crystal structures—metallic, ionic, covalent, molecular, and mixed-bond crystals—and integrates functions such as 3D model display, layer control, model switching, touch-based interaction, and crystallographic information retrieval, enabling intuitive visualization of unit-cell configurations and their structural characteristics. Built on the WeChat platform, the mini program is installation-free, cross-platform, and easily accessible, making it suitable for multiple teaching scenarios, including pre-class preparation, classroom demonstration, post-class review, and laboratory instruction. Teaching practice has demonstrated that the mini program effectively enhances the intuitiveness and interactivity of crystal structure instruction, helps students develop 3D spatial cognition, and provides a lightweight and scalable practical solution for the digital teaching of structural chemistry.
