Abstract: This paper analyzes the issues in the digital information construction of experimental teaching demonstration center in colleges and universities, highlighting the significance of education digitalization in the reform and teaching of chemistry experiments. Based on the characteristics of the chemical experimental center in Heilongjiang university, the paper summarizes the digital construction and exploration of the center in three levels: digital information platform, digital teaching resources and digital teaching mode. The center has developed digital teaching resources including chemical experiment safety with clear guidance and three-dimensional structure, virtual simulation with advanced system and comprehensive innovation, and basic chemical experiment with rich content and various forms. The blended teaching modes combining online merge-offline hybrid chemistry experiment safety, theory class, offline experiments, virtual simulations, and MOOCs have been established. The results achieved provide valuable insights for the digital construction of similar university laboratories.
