Virtual experiment method for MOOC to solve teaching practice skills and difficult points

Massive open online courses (MOOCs) bring us a new teaching method. Virtual experiment has the advantages of low costs and high using efficiency. The combination of virtual experiment and MOOCs can realize the open sharing concept, integrating quality theory, and experimental teaching resources. This paper presents software-based virtual experiment which not only could support the MOOC's operation simulation but also could realize the proper expression of the difficult problems in the MOOCs by visualizing the abstract problem with virtual reality technology. The design and realization of the virtual experiments platform for MOOCs is presented. The application cases used in the “College Computer Curriculum MOOC shows that the virtual experiment can be used for both virtual experiment support for large-scale online courses and show the teaching content of the important points and difficult problems in a more intuitive way, which can strengthen the combine with the theory of teaching closely.
