LED植物荧光粉制备虚拟仿真实验设计

Design of virtual simulation experiment for LED plant phosphor preparation

提出了LED植物荧光粉制备虚拟仿真实验的“一三X”设计思路,以Unity 3D为开发平台,软件的主菜单由“项目由来、实验原理、实验仪器、实验操作、应用提高”等9个菜单项组成;将“基于问题的探究式教学方法”融入到“原料选择、配比、称重、高温灼烧、XRD谱测试”等虚拟情景中;制订的“评分点多样—操作留迹—成绩反馈”实验评价体系,实现了对学生虚拟实验过程的科学测评,在应用物理专业实验的教学实践,学生反馈情况良好。

Put forward a train of thought of virtual simulation experiment of LED plant phosphor preparation which can be summarized as“one-three-X”.The main menu of this software includes the origin of the project,the experiment of the project,the instrument,the operation,the application and the improvement.Mix the problem-based inquiry teaching method and the virtual scene of raw material selection,proportion,weighing,high temperature burning and XRD spectrum testing together.Formulating an evaluation system of the diversity of scoring points-operation traces-performance feedback,which could make the scientific assessment for student virtual experiment process come true.During the process of the teaching practice for the experiments in applied physics,the project get a good feedback from the students.
