结晶学与矿物学虚拟仿真实验教学探索

Crystallography and Mineralogy Experimental Teaching Based on Virtual Simulation

针对北京大学主干基础课——结晶学与矿物学的实验教学进行改革,为满足实验教学中的对微观晶体结构的仿真。建设了结晶矿物学的实验课程信息化系统,将教学资源在线共享。根据课程要求构建晶体的三维模型并展示。采用桌面型3D打印机进行实体成型;利用激光切割机雕刻切割晶体资料链接页面的二维码,并镶嵌在对应晶体模型中。将虚拟仿真和3D打印,信息化技术与实验教学课堂紧密结合,使传统教学向信息化、虚拟化教学转变,建立了不受空间和时间限制的开放式课程资源共享的实验教学平台,拓宽了师生沟通的方法和渠道。

In order to meet the requirements of microcosmic crystal-structure simulation, experiment teaching of crystallography and mineralogy,which is a main basic course in Peking University,has been reformed. First,the experiment teaching information system of microcosmic crystal-structure is established by sharing the teaching resource online. Second,a 3D-model of mineral crystal is built. Last,using 3D-Printing technology,3D solid crystal is printed;using the laser cutting machine,the two-dimensional code is carved to link the page of the crystal data,and inlaid in the corresponding crystal model. This teaching reform tightly integrates virtual simulation and 3D printing,information technology and experiment teaching,and makes the transformation from traditional teaching method to information and virtualization,establishes the opening course resource sharing platform of experiment teaching which is not restricted by space and time. These broaden the methods and channels of communication between teachers and students.
