In the research, the author combined the current practice teaching with information-based learning to build an intelligent practice teaching system in which the virtual simulation and practice integrated with each other by using the teaching platform of high-quality. The system and methods constructed are applied to the professional practice and experimental teaching. At last, the significance of using virtual simulation to promote the improvement of practice teaching is shown through the introduction of reform and innovation of teaching content, teaching methods, operation mechanisms, management system, assessment objectives and so on.
