校园3D互动教学系统的构建与分析

Development and analysis of 3D interactive teaching system on campus

3D互动教学系统就是利用虚拟技术模拟难以讲解的教学场景,对于在现实生活中无法观察到的自然现象或事物的变化过程,以及一些不可能出现的场景(如金字塔是如何建成的,晶体内部结构,天体形成等),在3D教室呈现,为学生创设一个情景化的学习环境,多维度呈现学习内容,调动学生视觉、听觉、动觉等多感官参与,让学生们感受到极强的逼真感,使抽象的概念和理论更加直观化、形象。并且在3D教室中学生可以放心地进行各种实验(物理、化学)练习(如爆炸、化学反应、青蛙解剖等),不必担心由于操作失误带来各种危险。

3D interactive teaching system is to present the natural phenomena or the changing process of things that can＇ t be observed in real life and other impossible scenarios （such as how Pyramid is built, the internal structure of crystals, the formation of celestial bodies, etc. in 3D classrooms. A situation-based learning environment can be created for students and the learning contents can be presented in multi-dimentional way to arouse students＇ visional, auditory, kinesthetic and other sensory participation in learning and make the abstract concepts and theories more direct and concrete. In addition, students can practice various physical and chemical experiments （such as explosion, chemical reaction, frog anatomy, etc. ）without having to worry about various dangers caused by operational mistakes.
