Abstract: Addressing the significant imbalance in national virtual simulation experimental teaching resource distribution, particularly in Western regions where quality virtual resources are scarce, this study demonstrated the research and outcomes of a collaboration between Nanjing Agricultural University and Xizang Agricultural and Animal Husbandry University in the cross-regional co-construction and sharing of biological virtual simulation teaching resources, as well as the collaborative innovation of teaching models from 2017. By integrating existing virtual simulation teaching resources, the universities co-developed virtual simulation teaching resources with regional characteristics. Through establishing virtual teaching and research rooms, two universities explored and practiced collaborative innovation in teaching modes of virtual simulation experiment. The related work vigorously enhanced the information technology level of Western universities, assisted in curriculum construction and teaching reform, and provided a feasible path for the co-construction and sharing of virtual simulation experimental teaching resources for universities in Eastern and Western China.
