随着网络教育的蓬勃发展,虚拟实验的概念应运而生,并推动虚拟实验逐
步从理论研究走向实际应用。本研究针对传统化学实验教学中存在的问题,提
出虚拟化学实验教学的设计思路,并进行了设计与开发的实践尝试。
虚拟实验是依托“虚拟现实”技术而产生和发展的一种实验模式。目前
由于虚拟现实硬件设备过于昂贵,在化学实验教学中应用的虚拟现实形式大多
是桌面虚拟现实。桌面式虚拟现实主要依靠虚拟现实软件,虽然教学效果相对
沉浸式虚拟现实较差,但对传统化学实验教学仍然是一个很大的创新和提高。
本论文将桌面虚拟现实技术与多媒体技术、网络技术相结合,提出了一种基于
EON技术的虚拟化学实验的体系结构,并进行研究和设计。
本文在详细分析虚拟实验的理论基础、发展脉络、相关技术的基础上,着
重介绍虚拟化学实验的开发环境,并开发相关虚拟化学实验的教学设计实例。
在虚拟实验的概述部分,首先介绍了虚拟实验在国内外发展的现状和虚拟实验
的内涵和特点。其次在化学实验教学的理论部分,着重介绍了传统化学实验教
学的相关情況,分析在建构主义理论指导下的化学实验教学设计和传统化学实
验教学的不足,提出了对化学实验教学新形式的探索。在虚拟实验的相关技术
及开发环境部分,重点介绍3D技术和BON技术,最后在虚拟实验开发工具
EON STUDIO的环境下,完成一个铜与硫酸反应的化学实验的设计实例

Abstract
The Research and Design of Middle School Virtual Chemistry
Experiment Based on 3D and EON
Major: Education Technology
Graduate student: Liao ting Supervisor: Zhang song
Along with the rapid development of on-line education, the virtual experiment
experienced from academic research to practical application. The research put
forward the design method on the basis of the actuality of virtual chemistry
experiment and the problem of tradition chemistry experiment, at the same time
do some work on the design and research
Virtual experiment is a kind of experiment mode that produce and develop
relying on "virtual reality"technology. Presently, the form of VR mostly used in
chemistry experiment teaching is desktop VR. The desktop VR mainly depend on
VR software to be carried out with a little requirement to VR hardware which are too
costly to be used in experiment teaching. There is some difference desktop VR and
other more advanced forms of VR. But the traditional teaching chemistry
experiment is a great innovation and improvement. This paper will be desktop VR
and multimedia technology, network technology, presents a virtual chemistry
experiments based on the platforms of EON Technology Architecture, and the
conduct of research and design
After analyzing the theoretic basis, development clew, correlative technology
in detail, The research introduce the development environment, and give a desigr
example of virtual chemistry experiment instruction.In the part of
summarization Firstly, Virtual experiments in the development of the situation at
home and abroad and the contents and characteristics of VR
experiment. Secondly, In the part of the theory of chemistry experiment
Highlights outlined in the traditional teaching of chemistry experiment, Under the
