基于AR技术的初中化学实验设计与实现

Design and Implementation of Junior High School Chemistry Experiment Based on AR Technology

为了改善传统化学实验教学形式单一,提高学生学习兴趣,改善学生实验操作能力,避免反复试验造成的实验试剂的浪费,本文将化学学科与增强现实技术相结合,运用三维建模等相关软件,设计出可以进行虚实交互的初中化学中的铜与浓硫酸和铝热反应实验。学生可以通过桌面式实验平台进行虚实结合的实验并观察实验结果,而虚拟的实验环境也能够弥补传统化学实验教学上的弊端,排除潜在危险,提高了化学实验的安全性。同时,可视化的化学反应过程和人机交互式的学习过程,提升了学生学习化学的参与度和主动性。实践表明,增强现实技术在化学实验教学中的应用体现了学生在教学中的主体地位。

In order to improve the traditional teaching form of chemical experiments,enhance students'interest in learning,improve their experimental operation ability,and avoid the waste of experimental reagents caused by repeated experiments,the paper combines the discipline of chemistry with augmented reality technology,and uses relevant software such as 3D modeling to design a reaction experiment of copper with concentrated sulfuric acid and aluminothermal reaction in junior high school chemistry that can interact with reality.Students can conduct virtual and real experiments through a desktop experimental platform and observe the experimental results.The virtual experimental environment can make up for the shortcomings of traditional chemical experiment teaching,eliminate potential dangers,and improve the safety of chemical experiments.At the same time,visualized chemical reaction process and human-machine interactive learning process enhance students'participation and initiative in learning chemistry.Practice has shown that the application of augmented reality technology in chemical experimental teaching reflects the dominant position of students in teaching.
