【摘要】：化学作为一门实验学科,以实验为基础既是化学学科的特征,也是化学教学的特征。化学实验教学对学生动手能力、科学思维、创新意识的培养起着重要的作用。在传统的化学实验教学中因实验条件限制或者课时不够,学生思考时间太短,尤其农村学校由于缺乏资金和设备数量少,并不能让每个学生动手操作实验。要想保证实验教学的质量,必须改进传统的教学模式,采用新的教学手段,利用先进的教学设备进行教学。利用计算机仿真化学实验辅助教学,能够体现交互性,可以帮助学生更好的理解和掌握实验知识,培养学生的观察力、注意力和思维力。实践证明,计算机辅助教学将成为化学实验教学的一个重要途径。因此,设计和开发虚拟实验成为当前一个及其重要的研究议题,也是解决中学理化实验教学问题的当务之急。本论文结合人民教育出版社九年级(上册)化学,对氧气的制备、水的电解、氢气还原氧化铜等五个化学实验,进行虚拟实验软件的开发,力求实现虚拟性、实践性、灵活性、开放性和交互性的特性。并且整合了虚拟实验和真实实验,发挥各自的优势,取长补短,形成多功能的教学体系,从而吸引学生积极快乐地学习,这也是本论文设计的意义之所在。全文主要包括以下几部分内容：一、对计算机技术在实验教学中的应用进行了总结；阐述了计算机仿真实验对实验教学的辅助作用,介绍了Macromedia Flash作为开发平台的优势,操作界面和一些重要的概念。对初中化学实验类型进行了分类,讨论了虚拟环境下教学模式的选择,以及混合学习理论与虚拟实验教学的结合。二、利用Macromedia Flash完成了仿真化学实验系统的设计。对仿真化学实验开发的内容、设计思路及实验过程动画的制作、实验素材元件的制作、界面结构和风格等流程进行了详细介绍。三、通过利用“实验室制取氧气”、“水的电解”和“氢气还原氧化铜”几个虚拟实验的例子,对仿真化学实验与真实实验相结合的教学模式进行了举例性的设计。
[Abstract]:Chemistry, as an experimental subject, is not only the characteristic of chemistry, but also the characteristic of chemistry teaching. Chemistry experiment teaching plays an important role in the cultivation of students' practical ability, scientific thinking and innovative consciousness. In the traditional chemistry experiment teaching, because of the limitation of experiment condition or insufficient class time, the time of students thinking is too short, especially because of the lack of funds and equipment in rural schools, it is not possible for every student to operate the experiment. In order to ensure the quality of experimental teaching, we must improve the traditional teaching mode, adopt new teaching means and use advanced teaching equipment to carry out teaching. The computer simulation chemistry experiment can be used to help students to understand and master the experimental knowledge, and to cultivate the students' observation, attention and thinking ability. It has been proved by practice that computer-aided teaching will become an important way in chemistry experiment teaching. Therefore, the design and development of virtual experiments has become an important research topic at present, and it is also an urgent task to solve the problem of physical and chemical experiment teaching in middle schools. This paper combines five chemical experiments, such as the preparation of oxygen, the electrolysis of water and the reduction of copper oxide by hydrogen, to develop the virtual experiment software, in order to realize the virtual, practical, flexible, and so on, according to the chemistry of the ninth grade (first book) of the people's Education Publishing House. Openness and interactivity. And the virtual experiment and the real experiment are integrated to give play to their respective advantages, learn from each other, form a multi-functional teaching system, so as to attract students to actively and happily learn, which is also the significance of the design of this paper. The full text includes the following parts: The main contents are as follows: 1. The application of computer technology in experimental teaching is summarized, the auxiliary function of computer simulation experiment to experimental teaching is expounded, the advantages of Macromedia Flash as a development platform, the operation interface and some important concepts are introduced. This paper classifies the types of chemistry experiments in junior high school, discusses the choice of teaching mode in virtual environment and the combination of mixed learning theory and virtual experiment teaching. Secondly, the simulation chemistry experiment system is designed by using Macromedia Flash. In this paper, the contents, design ideas and animation of the experiment process, the fabrication of the experimental material, the interface structure and the style of the simulation chemistry experiment are introduced in detail. Thirdly, by using the examples of "making oxygen in laboratory", "electrolysis of water" and "reduction of copper oxide by hydrogen", the teaching model combining simulation chemistry experiment with real experiment is designed with examples.
