Categorization of Parts of Intelligent Virtual Experiment Development of Parts Database

在本研究中，我们开发了虚拟实验环境组件的本体、组件数据库和一个设计虚拟实验环境的创作工具。在本体的开发过程中，我们考察了已开发的几个虚拟实验，并分析了组成虚拟实验环境的功能和组件。在元件库中，用户可以使用开发虚拟实验环境所需的功能来检索元器件。创作工具帮助用户查找和组合组件。我们还开发了一个具体的虚拟实验环境作为例子，以验证本体的有效性和分析。思维实验环境是一个在计算机上模拟思维实验的框架，它为学习者提供了反映错误的有用信息，它是在分析的基础上设计的。提出了一种实现健壮性仿真的方法“PAC：Partial Constraint Analysis”，并进行了实现。这种方法对于生成基于学习者错误的行为模拟是必不可少的。通过计算基于学习者错误的数值行为，使用PAC生成基于错误的仿真来可视化错误。常规模拟与EBS的不同使误差变得明显。通过这些研究，我们对虚拟实验环境的组成部分进行了分类和排列。目前，这项研究只涉及机械问题。在整个物理学和其他科学领域拓展这一领域是我们未来的工作。

In this research, we have developed ontology for components of virtual experiment environment, database of the components and an authoring tool to design virtual experiment environment. In the developing the ontology, we examine several virtual experiments that are already developed, and analyze functions and components of that the virtual experiment environments are composed. In the database of the components, a user can retrieve components by using function the user needs to develop a virtual experiment environment. The authoring tool helps the user to find and combine the components. We have also developed a concrete virtual experiment environment as an example to the effectiveness of the ontology and the analysis. Thought experiment environment is a framework to simulate, thought experiment on computer, and provides useful information with learners for reflecting their errors, that is designed based on the analysis. We also have also proposed a method to realize robust simulation "PAC : Partial Constraint Analysis", and implemented. This method is indispensable to generate behavior simulation based on the learner's errors. By calculating the numerical behavior based on learner's error, with PAC, Error-Based Simulation is generated to visualize the error. The difference between normal simulation and the EBS makes obvious the error. Through these researches, we categorize and lines up components of virtual experiment environment. Currently, this research only deals with mechanical problems. To expand the domain in the whole physics and the other scientific domain is our future work.
