虚拟演示实验中知识情境的构建研究

Study on Knowledge Situation Construction of Virtual Demonstration Experiment

完整地再现知识生成、存在或应用的情境能够改善虚拟演示实验中的”浅学习”现象，从而促进学习者对知识的理解和迁移。虚拟演示实验的知识情境构建主要从情节、环境和指导三个方面进行，结合 “核裂变链式反应”实验的开发，分析了其具体的设计流程和实现方法。

The “surface─level learning” phenomenon can be improved in Virtual Demonstration Experiment by reproducing the situation of the generation， existence and utilization of knowledge， thus promoting the learner’s comprehension and transplant of knowledge. The knowledge situation construction of Virtual Demonstration Experiment can start with three aspects：Plus， Environment and Guidance. This paper analyzes the design processes and implementation methods with the development of Nuclear Fission Chain Reaction experiment.
