Looking back to the practical teaching in higher education in recent years, practical teaching has gradually shifted from purchasing specialized software and increasing university-enterprise cooperation projects to establish virtual stimulation teaching platform in order to improve the effect of practical teaching. However, the cost of the development of virtual simulation platform is high and the sharing degree between colleges and universities is low. Moreover, the sharing mechanisms advocated by colleges and universities are incomplete. In this paper, the sharing of practical teaching platform of virtual simulation is taken as a starting point, and it illustrates key technology, platform architecture and sharing strategies for practical teaching cloud platform. This platform integrates the exclusive resources centered on courses, virtual classroom, practical projects from colleges and universities into massive social education resources in the fields of discipline, major group. Taking the practical teaching sharing platform of virtual simulation of Fuzhou university as an example, the virtual teaching cooperative environment is constructed, which shows that the platform is feasible and effective and sharing within and outside the school as well as across regions has had a good teaching effect.
